What’s the best climate question to debate?

by Judith Curry

Andy Revkin poses a good question . . .

Over at dotearth, in the context of the U.S. presidential debates, Andy Revkin poses the following question:

While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear. What do you see as the best mix of achievable policies to limit environmental and economic regrets?

This is  a very good question to ponder, its at the heart of the climate policy debate.  How would you answer this question? For the moment, accept that there is ‘some’ warming that is attributable to CO2 (i.e. lets not debate the fundamental science here, but uncertainty assessments are ok).   Please keep your responses on topic.

  4. What’s the best climate question to debate?

    What is the empirical estimate for the climate sensitivity?

    Knowing its true value will make me very happy.

    • Joe's World(progressive evolution)

      Girma,

      There is no answer to that question.
      Every point on the planet has a different value at the same time and averaging to guestimate is a huge error.

  5. The Precautionary Principle says we should take no action until we are sure it will do no harm. Should we spend billions of dollars now potentially mitigating a hypothetical threat – and cause real harm to the poor, the old and the sick, OR should we apply the Precautionary Principle and wait until we know enough to balance tomorrow’s risks against today’s real harm?

    • Joe's World(progressive evolution)

      Who is to say that you cause more harm when ignorance can generate a response that REALLY could damage our currently comfortable climate.

    • The Precautionary Principle says we should take no action until we are sure it will do no harm.

      This is the kind of statement that renders skepticism, about basically any subject, essentially meaningless. It sets an impossible standard, and so becomes meaningless. It makes concerns about uncertainty meaningless.

      We can’t be sure that any action, of any type, to address any problem, won’t cause harm. The only purpose for such a statement is to confirm a bias.

      Should we spend billions of dollars now potentially mitigating a hypothetical threat – and cause real harm to the poor, the old and the sick,

      A similarly problematic statement, which renders “concern” about uncertainty meaningless.

      Skeptics need to start taking out the “skeptical” garbage.

      • Joshua, the PP deserves such a response. It is a rhetorical device. Humans have mechanisms in place already to address risk. As implemented, it is the UN version of risk management (PP) that needs to be ditched. It is used for personal or societial motivated reasoning, and causes conflagation of the real issues with potential climate change. Besides, it is institutional bias in apllication and in limits.

      • The Precautionary Principle is a Paean to Ignorance.
        ======================

      • John –

        The PP is easily polemicized by people on both sides of the debate to argue in favor of per-determined conclusions. In essence, it is a statement that caution in the face of potential risks is appropriate.

        More specifically, I see nothing wrong with the following as a general principle:

        “In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation

        The statement becomes complicated when we wade into the waters of uncertainty. That is to be expected.

        Demagogues on both sides seek to apply a binary mentality to interpret the PP – they seek to exploit complications rather than to deal with them. That isn’t a fault with the basic PP concept, but with how motivated reasoning undermines rational analysis. That fault plays out in many, many aspects of the debate, the PP being just one.

      • John,

        The Precautionary Principle is something I’m interested in:

        http://neverendingaudit.tumblr.com/tagged/precautionaryprinciple

        It might soon be retagged

        http://neverendingaudit.tumblr.com/tagged/precautionarytales

        Please note Martin Perterson’s Nature article. It might very well be the best you could argue against the PP.

      • Thanks Willard. That is a good write -up by Peterson.

        Joshua, the problem is that serious and irreversible, as well as sustainability have not been defined concretely. As Peterson points out, the meaning differs as or according to the individual. In this case, that persons are using motivated reasoning, such a construct would be expected to give worse results, since each gets to argue or define as they wish. Peterson found some utility for it. However, as it was promulgated, or rather since it was promulgated, it does not pass the consistancy test and needs to be ditched, or rendered to “advisement” category. The difference is that an advisement is usable, the PP as stated is worse than useless in uncertainty. It is just wrongly inconsistant with rules of decision making and with risk management practices which Joe Plodinec illustrates by pointing to how it can be inconsistant.

      • Latimer Alder

        @joshua

        ‘Threat’ is a lovely word for alarmists. It means nothing at all. Like being ‘in danger’. Neither mean anything without qualification, so – on your PP – could be used to justify any action at all that wanted to take.

        Weasel words indeed……

      • “lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation”

        Lack of scientific knowledge is more than sufficient reason to not do something that will most likely turn out to be something really stupid.

        When you clearly don’t forecast anything correct for fifteen years, shut up and sit down and gather more data.

      • Latimer –

        ‘Threat’ is a lovely word for alarmists. It means nothing at all. Like being ‘in danger’. Neither mean anything without qualification, so – on your PP – could be used to justify any action at all that wanted to take.

        I agree that the details behind “threat” or “dangerous” are the meat of the discussion. Qualification is the nut to crack. But as a general statement, the use of PP as I quoted seems just fine. John Plodnick’s usage of the PP above is certainly less valid.

        http://judithcurry.com/2012/10/08/whats-the-best-climate-question-to-debate/#comment-250201

        Weasel words indeed……

        Reflexive demagoging any aspect of the debate, the PP included, will get us all nowhere fast.

      • John –

        Joshua, the problem is that serious and irreversible, as well as sustainability have not been defined concretely.

        I agree.

        In this case, that persons are using motivated reasoning, such a construct would be expected to give worse results, since each gets to argue or define as they wish.

        So what it boils down to is the intent of the discussant. If someone wants to demagogue the use of the PP, they will do so – just as we see with any aspect of what anyone says in the debate.

        The difference is that an advisement is usable, the PP as stated is worse than useless in uncertainty.

        I don’t think it’s particularly useful without clarification – but I don’t think that it is worse than useless until people demagogue it. I see it as a fine principle to use as a basic starting point – and from there it becomes more meaningful as qualification is added. But we can’t even start down that road when people are motivated to throw obstacles in the path by demagoging basic cautionary principles.

        It is just wrongly inconsistant with rules of decision making and with risk management practices which Joe Plodinec illustrates by pointing to how it can be inconsistant.

        I haven’t read the link – but it seems to me that as a general statement, of course it can be inconsistent. Why would anyone expect otherwise? Holding a general statement hostage to uniform consistency is pointless. The point is to burrow down to explore the concept of consistency in specific context. How do we do that if people are so focused on rejecting basic cautionary principles. Again, I will refer back to this post:

        http://judithcurry.com/2012/10/08/whats-the-best-climate-question-to-debate/#comment-250201

        Please read again my response to that post. With the attitude John Plodinec expresses, no one can get anywhere.

      • Joshua you say “but it seems to me that as a general statement, of course it can be inconsistent. Why would anyone expect otherwise? Holding a general statement hostage to uniform consistency is pointless” There appears to be a logical or procedural error here. Without concrete definitions, motivated reasons will surface and comprise most if not all the discussion. With the human tendency to engage in such reasoning, it is as I claim worse than useless. It will waste time, first fighting over what the definitions are and how the definitions are related within a mental construct, that then has to be argued as well. With the construct dependent on the underlying weak defintional relationship, the construct will soon be demolished by the participants as they use parsing to re-entrench their position. The merits of any consideration will be then subsumed by this fight to retrench. In fact this was linked by Willard, IIRC, over at Keith’s in an article discussing sustainability and how even those who wanted to support the concept had problems first communicating, then secondly coming to concrete decisions because of the lack of definition.

      • John –

        There appears to be a logical or procedural error here. Without concrete definitions, motivated reasons will surface and comprise most if not all the discussion.

        I see your point. It has merit. The article Willard linked (http://www.nature.com/embor/journal/v8/n4/full/7400947.html) is also quite interesting.

        The PP in and of itself does not create motivated reasoning, wasteful re-parsing, etc. Those phenomena are ubiquitous. Time-wasting is ubiquitous. The PP is just one arena where they surface. And so I object to anyone focusing on the PP as causal w/r/t creating problems. This is not entirely unlike previous discussions you and I have had about locating causation.

        I think that the PP can be useful as a starting point. Sure, a problem occurs if someone uses it as an end-point, as a reason to dismiss cost/benefit analysis (as described in the linked article). And on the other side, if someone seeks to use the PP as a way to dismiss earnest attempts to make caution appropriately contextualized, a problem occurs.

      • John –

        I should clarify:

        And on the other side, if someone seeks to use the PP as a way to dismiss earnest attempts to make caution appropriately contextualized, a problem occurs.

        By that I mean that if someone uses attacks on PP as a way to dismiss attempts to make caution appropriately contextualized (for which I think using the PP can be an appropriate starting point), a problem occurs.

      • JOshua, I agreee with your comments in general. In specific, I point out as Bart indicated it works unless someone games the system. My point is and has been the UN and through the IPCC are gaming the system. The UN with Rio Declaration and its version of PP that removes tools used in risk management; and the IPCC with its institutionalized biaas that precluded that climate change is real and a threat. By stating threat as they did, one cannot use conservation of capital or status quo, as a legitimate reason to avoid potential costs in an uncertain result. As stated it is either contridictory or it is biased. Neither is correct.

      • “precluded” is the wrong word substitute “predetermined.”

      • ‘pre-concluded’.
        ==========

      • Hansen said this himself in several of his Science papers. Do the things that it makes sense to do any way.

        Things like cutting down on emissions black soot from dirty coal help air pollution, reduce respiratory disease, and will not leave soot to absorb energy in the atmosphere or on snow/ice.

      • Are you kidding? That makes too much sense.

      • Didn’t dirty coal power plants in China paused the global warming?

      • Joshua, I have a house in France, actually it’s two houses, one built sometime in the 18th Century and the other earlier, but of unknown provenance. Mrs. Geronimo saw some dust that could have been wood on the kitchen table. Should I:

        1. Spend a couple of thousand Euros getting house treated for termites and woodworm immediately?
        2. Spend a couple of hundred Euros treat only the room we’ve seen the “wood” dust in?
        3. Wait to see if there are any other persistent signs of wood infestation?

        The world has warmed by approximatel 0.8C over the last 150 – 200 years, there are no signs at all that this has been detrimental, all the “signs” have transpired not to be true, like the 50 millions climate change refugees by 2010 on the UNEP site. ( Now eradicated).

        So I guess the question should be:

        “How much are you prepared to pay for mitigation of CAGW if the theory turns out to be wrong?”

      • The prevailing Alarmist Precautionary Principle is that unless we can be sure there isn’t CAGW, we should pour $billions into it and massively expand the state.

        Funny, I don’t recall Joshua, Web or any of the other alarmist crackpots on this site ever complaining about it.

      • John Plodinec is correct. From an expert on the Precautionary Principle:
        Sunstein, Cass R. “Throwing Precaution to the Wind: Why the ‘Safe’ Choice Can Be Dangerous.” Opinion. Boston.com – The Boston Globe, July 13, 2008. http://www.boston.com/bostonglobe/ideas/articles/2008/07/13/throwing_precaution_to_the_wind

      • Pooh,

        Thank you for the OP-ed.

        Sunstein only attacks what he calls the stronger version . His reductio ad absurdum are limited to the stronger versions of the PP:

        > The most limited versions of the principle suggest, quite sensibly, that a lack of decisive evidence of harm should not be grounds for refusing to respond. Controls might be justified even if we cannot establish a definite connection between, for example, low-level exposures to humanly-introduced carcinogens and adverse effects on human health. Thus the 1992 Rio Declaration, setting out principles for sustainable development, states, “Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.”

        http://www.boston.com/bostonglobe/ideas/articles/2008/07/13/throwing_precaution_to_the_wind/?page=full

        As an aside, the byline only states that Cass Sunstein is a law professor, so the article alone does not provide evidence that he’s an expert on the PP.

      Does that include not pumping gigatons of CO2 into the atmosphere until we are sure it will do no harm?

        Yes, I am. The demonstration has already occurred. You acknowledge as much in your initial claim. Gigatons of C02 and no harm.

        Andrew

      • This is a rather typical example of how demagogues exploit complications in the concept of the PP to serve a partisan goal.

        Even assuming that it can’t be “proven” that anyone has been “hurt by it” yet (which, btw, is absurd anyway – given that we all know, clearly, how ACO2 from a variety of sources has negative impact in addition to affecting the environment), the PP in the context of the climate debate refers specifically to the potential of future impact on the climate.

        Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation

        If you want to argue about whether there are threats, knock yourself out, but that is a different issue. Polemicists on one side want to use the PP to argue that climate change policy is a must, and polemicists on the other side want to use the PP to argue that climate change policy is completely unfounded. Neither group is actually arguing on the basis of the PP, but merely from their own biases.

      • BTW – Louise – just to be clear, my reference to demagogues was to BA.

        I don’t think that we ‘all know’ this at all.

      • On what basis? What evidence would you cite? What ‘negative impacts’ are there?

        Sorry, Latimer. I see no reason to answer those questions. That ACO2 has harmful impact irrespective of any potentially harmful influence on climate change (and I’ll even throw in geo-political negative externalities as an exclusion for the sake of argument),is completely obvious are obvious to anyone who is serious about this issue and is even remotely interested in a good faith discussion. (Please note, someone not stuck in a binary mentality can see that the existence of negative impacts is not mutually exclusive with the existence of positive benefits).

        That you would even ask those questions serves my purpose sufficiently to point out the difference between “skepticism” and skepticism.

      • David Springer,

        Once we establish the physical basis of what CO2 does, we could follow up by looking at its biogeochemistry, one of the chapter Latimer Adler might have glimpsed, if only because his alleged background in chemistry:

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7.html

        Online bitch-slapping does not hurt much. In fact, I see no reason for you to motivate me to drop citation after citation of documents you’re supposed to have read. Quotes will soon follow.

        Meanwhile, please don’t choke on your Thanksgiving popcorn.

      • Latimer Alder

        @willard

        Chapter 7 of IPCC WG1 discusses very few linkages between ACO2 and bad things other than climate.

        Here is the executive summary

        ‘Emissions of carbon dioxide, methane, nitrous oxide and of reactive gases such as sulphur dioxide, nitrogen oxides, carbon monoxide and hydrocarbons, which lead to the formation of secondary pollutants including aerosol particles and tropospheric ozone, have increased substantially in response to human activities. As a result, biogeochemical cycles have been perturbed significantly’

        You will note that CO2 is lumped in there with every other unpleasant gas they can think of. I think (for example) that CO2 has almost no influence on tropospheric ozone.

        So – once again – where please are the ‘obvious’ parts of Joshua’s proposition?

        ‘That ACO2 has harmful impact irrespective of any potentially harmful influence on climate change is completely obvious’

      • Latimer Adler,

        There is no hurry to try to satisfy your request, if all you have is bitch-slapping. In fact, I see no reason to believe you ever were satisfied.

        From the introduction:

        > An important aspect of climate research is to identify potential feedbacks and assess if such feedbacks could produce large and undesired responses to perturbations resulting from human activities. Studies of past climate evolution on different time scales can elucidate mechanisms that could trigger nonlinear responses to external forcing. The purpose of this chapter is to identify the major biogeochemical feedbacks of significance to the climate system, and to assess current knowledge of their magnitudes and trends. Specifically, this chapter will examine the relationships between the physical climate system and the land surface, the carbon cycle, chemically reactive atmospheric gases and aerosol particles. It also presents the current state of knowledge on budgets of important trace gases.

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-1.html

        I hope you do not find the emphasized sentence too gnomic.

      • Louise,

        The burden of proof is on those claiming some harm. Otherwise mankind would be unable to ever make any change or introduce anything new.

      • Latimer

        you asked about impacts.

        http://www.ipcc.ch/publications_and_data/ar4/wg2/en/contents.html

        So, if your question is about the citations for the scientific basis for the effect C02 has that would be WG1 ( and skip chapter 7 there isnt much of interest there) If your question is about impacts, then WG2.

      • Joshua:
        Concerning your posts: Personal denigration is not discussion.

      • Latimer Alder

        Thanks Steven

        But the actual point I was trying to establish was whether Joshua could substantiate his assertion that

        CO2 has so many bad effects – in addition to climate change – that they are obvious (paraphrase).

        It was not a discussion about climate change. It was not a discussion about radiatve physics. It was a discussion about the effects *In addition* to these things. And the *obviousness* or otherwise thereof.

        Somewhere along the way various participants seemed to have lost track of the point of the discussion and wandered off into academic wordgames, philosophy, epistemiology and insults.

        It was a very simple, straightforward and reasonable question that could have been answered in a minute or two. But it seems to have caused much angst with a number of participants.

        En passant I wonder how many other environments there are where a participant/participants is/are so discumnockerated by being asked to justify an assertion that such events ensue.

        Is this an academe only thing? A climatology only thing? A US thing? Because in my experience in commerce is that it is entirely normal practice. Most discussions/presentations/meetings I have ever attended thrived on lively debate and discussion….One would be extremely ill-advised to make such an assertion without having the facts to back it up to hand. One can almost guarantee that somebody will want to examine it in public.

        I’ve never had direct dealings in the Far East, where seniority and ‘face’ are far more important than they are in Western culture. But as far as I can tell Joshua is not from an Eastern culture.

        So it is all very very mysterious,……

        Thanks for the link anyway.

      • Compare and contrast:

        1. Latimer Adler’s paraphrase:

        > CO2 has so many bad effects – in addition to climate change – that they are obvious.

        2. Joshua’s first claim:

        > Even assuming that it can’t be “proven” that anyone has been “hurt by it” yet (which, btw, is absurd anyway – given that we all know, clearly, how ACO2 from a variety of sources has negative impact in addition to affecting the environment), the PP in the context of the climate debate refers specifically to the potential of future impact on the climate.

        To better understand the “variety of sources” Joshua had in mind he suggested this:

      • Cass Sunstein is perhaps unmatched among Harvard lawyers; he’d have you not only eagerly throwing the baby out with the bathwater, but going out to look fanatically for babies to toss without wasting that troublesome middle bath step.

        The Precautionary Principle is always a tool of last resort; otherwise you end up caught on the horns of Sunstein’s many seeming dilemmas over and over again. Have sufficient knowledge to act? Then the Precautionary Principle doesn’t apply. Have sufficient knowledge to decide acting is less risky than inaction? Then the precautionary principle leading to inaction does not apply.

        Sunstein is wise to closely examine the principle and point up inappropriate applications of it case by case. We are unwise if we draw from Sunstein’s work that the principle (over a dozen distinct precautionary principles are extant, dependent on situation) is wrong, just because it can sometimes lead to wrong outcomes in situations where there is no good way to predict what action to take.

        Absent the precautionary principle, after all, we’d have a situation where every action, however ludicrous, should not just be allowed but pursued, and not just by individuals who choose to but by government enforcing actions by command and control, regardless of the reluctance of individuals.

        Selected Principles
        Principle 1

        Human beings are at the centre of concerns for sustainable development. They are entitled to a healthy and productive life in harmony with nature.

        Principle 15

        In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities.
        Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.

        Reading the cite, check out the mentions of “sustainable development”. You might note that “Global Warming” (aka “Climate Change”) has been subsumed within “Sustainability”.

    • It seems that perhaps the only thing that the Precautionary Principle is good at is deflecting discussion from legimate topics. The exception proving the rule: the very act of deflecting topics does promote discussion of the utility and limitation of the Precautionary Principle. Well, it should anyway.

      • It seems that perhaps the only thing that the Precautionary Principle is good at is deflecting discussion from legimate topics.

        That is contingent on the intent of the discussants. It seems a failure of personal responsibility to “blame” the PP for how people choose to demagogue a rather simple and important concept.

        When people have such intent, there is nothing that can’t be demagogued. And when people fail to hold demagogues to account, nothing will change.

        Same ol same ol.

      • “That is contingent on the intent of the discussants. ”

        How about ‘That is A RESULT OF the intentS of the discussants’ ?
        It is in part because of that aspect applies to discussants of all stripes and colors that the Precautionary Principle is potentially useless. You can not remove the people from the process. To me one can not use any tools, e.g., the PP, without trying to come to grips with it limitations in decision-making.

        “When people have such intent, there is nothing that can’t be demagogued (sic). And when people fail to hold demagogues to account, nothing will change. ”

        Concur with that.

    • Could I ask, which PP are specifically referring to?

      I’m acquainted with over a dozen distinct precautionary principles.

      You seem aware only of part of one.

      Are you sure you’re familiar enough with the topic to make such sweeping statements with such simulated authority?

    • My personal opinion is that any discussion where the PP is brought into play is one of people who suffer from another form of PP – peeing in their panties.

        All variations of the Precautionary Principle.

        The Precautionary Principle is a situational mathematical construct of Game Theory, applied to circumstances where a player seeks an optimal strategy in the absence of some information.

        Nothing in this thread so far has developed the theme of what information is missing, compared to decision needs, though Latimer and Joshua danced around the topic of ignorance and whether we can call information absent just because some choose to dodge it.

        I contend we have all the information we need to make many informed decisions about climate policy, so the Precautionary Principle does not apply except in a few detailed cases.

        We understand that the carbon cycle is exhibiting scarcity, that it is rivalrous, that we can exclude lucrative uses of it from the Market; for Capitalism that is all we need know to demand its privatization, as a merely technical economic question. Once we know this, failure to privatize is theft from the many by the few condoned by an ineffective government.

        We understand that there are Risks no one sought or consented to being imposed on the many by the few; while there may be some benefits — largely overblown used-car salesmanishly — that again no one sought or defined as benefits for themselves, we can never argue the benefits against the costs as there is no consent. A farmer who dumps a load of manure in the town well so he can sell water from his own well at a steep price does not get to argue how much greener the town square may be next year for the application of all that fertilizer. A load of poisonous BS remains a load of poisonous BS.

        Where might one or more of the various Precautionary Principles apply? Certainly we’d want to apply the Precautionary Principle against overuse of Cap & Trade or of increasing government revenues through new taxes or of expanding the command and control regulatory powers of the state.

        We expect Cap & Trade systems to be more easily exploited the more general their application, the wider they cast their nets: although there are some cases where Cap & Trade might be the most effective and efficient instrument of privatizing the carbon cycle in some industries, these are certainly the minority of the entire economy: when faced with the choice of Fee & Dividend vs. Cap & Trade, the Precautionary Principle thereby indicates we ought favor Fee & Dividend as it is likely the lesser drag on the Market.

        We expect, given the finding that Retail taxes produce less of a drag on the economy than Income taxes that if a government decides it must raise new taxes (perish the thought), then it ought by the Precautionary Principle do so by reducing the Income Tax rate so low as possible and raising the Retail Tax rate to meet the needs of the state — for instance to pay off debt accumulated by fighting foreign wars.

        Likewise, since we know committees and bureaus of experts tinkering with any large and complex enough system of exchanges lack enough good information and the response time to react to changing conditions when compared to the democracy of individual exchanges in an efficient and fair Market, the Precautionary Principle tells us to beware of creating command and control committees and bureaucracies when a Market mechanism can instead achieve the same results.

        The Precautionary Principle is the heart of the Capitalist system. Honi soit qui mal y pense.

      • johnfpittman

        Bart R stated correctly for a general construct, “The Precautionary Principle is a situational mathematical construct of Game Theory, applied to circumstances where a player seeks an optimal strategy in the absence of some information.” However, the PP as promulgated by the UN, chose an optimal solution for THEIR desires. That is the PP’s, in all its forms, weakness. Different persons, organizations bring different theories as to what should be optimized, different ideas as to how much to risk, not only when information is available, but especially when information is not available. Even the ratio of known to unknown will effect others differently. The problem with PP is that it allows “players” to try to change the rules for actualization. To actualize, one needs the capabilities, and the oppurtunity to do so. The PP tries to limit the capability when the oppurtunity is avavilable. The reason it fails is that is claiming an ability it does not have wrt knowledge and uncertainty. If one has knowledge, the solution is straightforward. If one has uncertainty, risk management has been the solution in the past. Now persons want to use the PP with conditions of uncertainty to trump the capability of a possible good outcome that they consider “risky” or preclude the use of capital conservation in an uncertain situation. But note the contradiction the UN PP has Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.” How can one in the face of actual uncertainty propose cost-effective measures? There will be intrinsic and extrinsic assumptions to be made that differ to the point that they appear 180 degrees opposite of each other; and yet each can claim to meet the PP within the set of assumptions made. The assumption of whether CO2 will be a net benefit or net loss and at what point it MIGHT reverse from one to the other.

      • willard continues to impress and surprise.

        Sen and Nussbaum is certainly a step up in the discourse, and could be six or seven topics for Dr. Curry’s salon, given the number of people who persist in making assertions about development economics and the lesser developed world, generally without foundation.

        Ampliative logic, likewise, and the other non-classic systems, don’t generally get much time from me in discussion, given that most people have trouble with simple predicate logic as it is, despite the delight I take in them. Sure, so long as you preface your logic with a notation indicating your logical system (though technically, it’s a form of reasoning, not of logic, to my way of thinking), I’m all for entertaining exchanges along those line.

        In case you haven’t noticed, I’m frequently ampliative myself.

      • johnfpittman | October 9, 2012 at 9:25 am |

        “..as promulgated by the UN..” That’s just plain hooey.

        John Plodinec | October 8, 2012 at 9:03 am | isn’t the UN. It’s his application of the PP we’re discussing, not the UN’s.

        Could you show me a cite for the UN where it details its rationale for its specific application of the Precautionary Principle? It’s entirely possible the UN is as ignorant of how to apply this principle as anyone in this thread; but I think it more likely you’re makin’ stuff up.

        There is nothing in the construction of the principle that conforms to what you say about it.

        “However, the PP as promulgated by the UN, chose an optimal solution for THEIR desires.”

        If this is what the UN did, then it’s not the Precautionary Principle; reasoning from the conclusion to the premise is always an error of Logic, and the PP is a tool of Logic.

        “That is the PP’s, in all its forms, weakness. Different persons, organizations bring different theories as to what should be optimized, different ideas as to how much to risk, not only when information is available, but especially when information is not available.”

        Different parties bring different considerations to the table when they construct the situation they apply the Precautionary Principle to. This is true.

        “How much to risk,” has nothing to do with the Precautionary Principle, however. The principle is invariant to amount risked.

        Also, you simply can’t apply the Precautionary Principle when information sufficient to a decision is available; it’s a contradiction in terms.

        “Even the ratio of known to unknown will effect[sic] others differently.”

        Which is why there are Precautionary Principles – general precepts to mathematically determine correct decisions for given situations of knowns and unknowns. It would be the absence of an agreed on principle that would allow some to be affected differently than others.

        “The problem with PP is that it allows “players” to try to change the rules for actualization.”

        Uh.. No. You’re describing ‘gaming the system’ or ‘metagaming’, and not the Precautionary Principle.

        One example of gaming the system is to redefine terms to weaken their use when they disadvantage your play. Like people who hate the Precautionary Principle frequently do (for example in this thread) by makin’ stuff up about it that just ain’t true.

        “To actualize, one needs the capabilities, and the oppurtunity[sic] to do so.”

        Motivational speaking 101?

        The PP tries to limit the capability when the oppurtunity[sic] is avavilable.

        About half of all Precautionary Principles apply to situations where the mathematically correct outcome given Uncertainty is to restrict attempts to take advantage where there likeliest is none until such time as the non-perishing advantages may be correctly exploited.

        Oil in the ground keeps, for instance. A hundred years from today it will be more, not less, valuable than today (by all indications). It’s not a perishing resource. So Carpe Diem does not apply, except in the sense that the lifespan of some individuals who want money in their pockets from that oil is itself perishing and they have no regard for their descendents.

        The other half of Precautionary Principles by symmetry apply to situations where failure to take advantage of an opportunity results in likely loss. And guess what? They just don’t apply very much to the situations of Climate Change avoidance; inevitably over the longest term the Risks on both sides are so unbalanced as to make it ludicrous to propose boldly continuing to change the climate in ignorance.

        “The reason it fails is that is claiming an ability it does not have wrt knowledge and uncertainty.”

        Okay, now you’ve asserted the failure of an entire branch of mathematics without presenting a single mathematical argument, a single example of correct logic, or even a single true statement.

        “If one has knowledge, the solution is straightforward.”

        If one has knowledge, then the Precautionary Principle doesn’t apply.

        “If one has uncertainty, risk management has been the solution in the past.”

        Uh.. what?! Have you ever done the least reading on Risk Management as a distinct pursuit? The Precautionary Principle is one of the mainstay tools of Risk Management. Or do you mean ‘risk management’ in lowercase, by which you mean gambling and hoping you don’t have to resort to the social safety net, leeching off your family, getting government bailouts because you’re too big to fail, or going bankrupt and leaving your creditors in the lurch? Because it sounds like what you’re saying is it’s okay to make bad decisions by ignoring precautions because you can count on someone else to pay for your mistakes.

        “Now persons want to use the PP with conditions of uncertainty to trump the capability of a possible good outcome that they consider “risky” or preclude the use of capital conservation in an uncertain situation.”

        Is this even a sentence?

        Yes, it’s true, mathematically sometimes Uncertainty does mean the good outcomes some imagine aren’t real, and the Precautionary Principle recognizes this reality.

        Don’t want to accept reality? That’s fine. Just don’t do it on someone else’s dime. That’s simply begging for the charity of others to bail you out when your fantasy falls apart.

        Once the Precautionary Principle is applied, there remains plenty of room for Risk still, and plenty of opportunity for gain by taking risks; there remains plenty of rational exploitation of resources to do, and plenty of upside to see. The Precautionary Principle merely constrains the downside of uncertainty. It doesn’t even guarantee that all downside is avoided. It just guarantees that on the whole you haven’t made the downside inevitable so far as can be known.

        “But note the contradiction the UN PP has Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.”

        Aha. You do have a quote from some UN document somewhere. Title? Page? Date published? Would be nice if you provided enough information to confirm your quote. Or even quote marks around it.

        “How can one in the face of actual uncertainty propose cost-effective measures?”

        You mean cost-effective based on cost-benefit analysis compared to the serious damage; they appear to mean compared to the threats. Simple reading comprehension mistake. Anyone could make it. Of course, confirmation bias makes it more likely to succumb to.

        “There will be intrinsic and extrinsic assumptions to be made that differ to the point that they appear 180 degrees opposite of each other; and yet each can claim to meet the PP within the set of assumptions made.”

        Because there are symmetrical Precautionary Principles, and you appear to be acquainted (though barely) with part of only one.

        “The assumption of whether CO2 will be a net benefit or net loss and at what point it MIGHT reverse from one to the other.”

        Unsought benefits of CO2 (way overblown from what I can tell) don’t count in any Precautionary Principle. An unsought benefit is like unsought procreation. The attacker is the only one having any fun.

      • Bart,

        John might be referring to the 15th principle of the Rio declaration:

        > In order to protect the environment, the precautionary approach shall be widely applied by States according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.

        http://www.unep.org/Documents.Multilingual/Default.asp?documentid=78&articleid=1163

        As formulated, it is more an anti-anti-precautionary-principle than the PP, but we’ll wait until the discussion gets more constructive (?) to note the difference.

        According to my rhetorical models, a flurry of appeals to ignorance might likely be forthcoming.

        ***

        In any case, it would be interesting to know if this 15th principle is referring to Sen’s capability approach:

      • Summarized as : Don’t let the lack of facts ruin a good excuse for meddling.

      • Nice link Willard. Your linked work is a subset of the work done by biologists in the pursuit of explaining evolution. Perhaps even partly a superset since the work goes into the legal and moral dimensions from what I read.

        Bart R, I failed to realize you would not understand my point was from the perspective of the UN, since I stated so. I note you asked JOhn Plodinec, but I did not see an answer. HIs “Should we spend billions of dollars now potentially mitigating a hypothetical threat” wrt to the thread I inferred was about climate change and the UN sponsored mitigation efforts proposed; otherwise his comment does not make much sense to me. Bart I have been engaged in different types of risk management from the informal to the formal for 26 years as an engineer. In particular I agree with “perishing” or not resources. This is where I point out that the UN has defined it such that capital conservation or risk avoidance is trumped in their declaration. Yes, and I agree it is confirmation bias and motivated reasoning on their part. Yes, I was pointing out that the UN is gaming the system. It is not that I am unaware, but I have a question that may cut to some of the misunderstanding. I note you use PP in both singular and in plural. My question are you taking about the same PP I and others are, such as outlined in the UNESCO document “The Precautionary Principle” March 2005?

      • John,

        I suppose you mean this document:

        http://unesdoc.unesco.org/images/0013/001395/139578e.pdf

        Am I correct?

        At last, something to read!

      • If that’s the document, here’s the working definition from Box 2:

        When human activities may lead to morally unacceptable harm that is scientifically plausible but uncertain, actions shall be taken to avoid or diminish that harm. Morally unacceptable harm refers to harm to humans or the environment that is

        – threatening to human life or health, or
        – serious and effectively irreversible, or
        – inequitable to present or future generations, or
        – imposed without adequate consideration of the human rights of those affected.

        The judgement of plausibility should be grounded in scientific analysis. Analysis should be ongoing so that chosen actions are subject to review. Uncertainty may apply to, but need not be limited to, causality or the bounds of the possible harm.

        Actions are interventions that are undertaken before harm occurs that seek to avoid or diminish the harm. Actions should be chosen that are proportional to the seriousness of the potential harm, with consideration of their positive and negative consequences, and with an assessment of the moral implications of both action and inaction. The choice of action should be the result of a participatory process.

        I’m not sure this is the PP as BartR is used to regard it.

      • johnfpittman

        Yes Willard. It is one to read. Did you see my question about Sen wrt Nussbaum?

      • > [R]easoning from the conclusion to the premise is always an error of Logic, and the PP is a tool of Logic.

        To be fair, we must say that what BartR says applies to logics that are not ampliative:

        > Arguments that are deductively invalid are ampliative. Their conclusions contain information that is not present in their premises, they go beyond the information given in their premises. In some cases this is obvious. When we draw a conclusions about what all voters in Quebec prefer based on premises describing the preferences of a sample of Quebec voters our conclusion goes beyond the information in our premises (here to voters that we didn’t sample).

        http://plato.stanford.edu/entries/relativism/supplement3.html

        Ampliative logics have been developed to model what we can call creative forms of reasoning. One such instance is abductive reasoning:

        > For Charles Peirce, who coined the term “abduction” a century ago, the introduction of unifying conceptions was an important part of abduction [11, 25], and it would be unfortunate if our understanding of abduction were limited to more mundane cases where hypotheses are simply assembled. Abduction does not occur in the context of a fixed language, since the formation of new hypotheses often goes hand in hand with the development of new theoretical terms such as “atom,” “electron,” “quark,” “gene,” “neuron” and “AIDS.”

        This note is mostly an excuse to cite this classic of cognitive sciences. But there is also this intuition I can share: should we model the PP in an ampliative way or not? If we determine that precaution acts like an induction principle, we could build a reasoning system like the one with which BartR might be more familiar. On the other hand, it does not appear to be faithful (at least prima facie) with the Unesco or the UN formulation.

        Something to chew on, unless of course one prefers to simply whine or bitch slap.

        >

      • The UN Precautionary precept must be the weakest precautionary principle I’ve ever seen, restricting itself strictly to when “..human activities may lead to morally unacceptable harm that is scientifically plausible but uncertain,..” which anyone would have to call, once they worked out that it means only when scientifically there is likelihood of unacceptable moral harm but doubt of exactly where the likelihood begins due to the limits of science to predict that “..actions shall be taken to avoid or diminish that harm.”

        I mean, think about what that says: strapping babies to a rocket sled and firing them toward a solid barrier is perfectly acceptable, so long as there’s no doubt about exactly how long before they run into a concrete wall. Well, okay, we can be pretty sure the UN meant to capture absolute certainties. But it’s still a mathematically weak condition, what with the “or diminish,” and with the failure to refer to justice, blame, responsibility, payment, compensation, consent, or any other ordinary term or concept related to trespass. They certainly could go much farther, without even catching up with the common law or international trade law or even other declarations of the UN.

        Morally unacceptable harm refers to harm to humans or the environment..”

        – threatening to human life or health, or
        – serious and effectively irreversible, or
        – inequitable to present or future generations, or
        – imposed without adequate consideration of the human rights of those affected.

        If that’s the precaution you’re offended by, if you think it’s your entitlement to kill, hurt or otherwise trespass on the rights of others for no compelling and equitable reason, then you fulfill every definition of a psycopath..

      • “if you think it’s your entitlement to kill, hurt or otherwise trespass on the rights of others for no compelling and equitable reason, then you fulfill every definition of a psycopath”

        This is precisely what makes the UN/IPCC a psycopathic organization. It should be immediately culled before it does any more harm.

      • Bart, if your question “If that’s the precaution you’re offended by” is directed at me or my comments, or if you don’t mind me commenting, it is with the weakness of the UN PP construct that would instruct the UN and countries to engage in indirect harm that meets the four criteria you listed in the effort to prevent climate change or environmental harm, besides precluding a good precautionary principle of conserving in the face of real uncertainty, or conserving and solving the problems such that the indirect harm does not occur. As stated, this PP, I find logical or use inconsistant, if not outright contradictory if one assumes a situation that has more than two or three complications or is complex in nature, such as we know reconstructing our main energy use would be, or the results of climate change itself.

    • John Plodinec

      Willard:-

      You’re correct – the UNESCO formulation, which I sort of bowdlerized. I am decidedly not a fan of the PP for most of the reasons cited against it. However, as far as I can tell, it is the only basis for questioning what to do – if anything – about climate change at this point in time. Frankly, I think it would be silly to even talk about it in the debates given the real problems we have to solve today.

      • John Plodinec,

        No harm, no shame.

        My personal impression is that the PP has merits. As auditors are fond to say:

        > If I had a big policy job, in my capacity as an office holder, I would be guided by the reports of institutions such as IPCC rather than any personal views (a point I’ve made on a number of occasions); and that I believed that policy decisions could be made without requiring “statistical significance” ( such decisions are made in business all the time, and, in all my years in business, I never heard the words “statistical significance” pass anyone’s lips as a preamble to a business decision.

        See also:

        Common sense and prudence guide most decisions in life. It also helps win football championships. I surmise that this also applies to ClimateBall, where one big mistake can ruin one blogger’s reputation, more so if it’s a blogger with an attitude. (Hi Tamino.)

      • Yes, but one should not tie the hands of policy makers by setting standards that preclude useful tools for success as the UN has.

        On another note. Willard: I find the “group concept” better than the consequentialism (sp?) of that author. I agree with the critics on Philosophy Bites, IIRC, Consequentialism is too prone to taking shortcuts and using it as a tool for motivated reasoing. I will have to look into Nussbaum in detail. The snippets I read support the hatchet job I read. However, the critic presented no depth of contemplation that should be inherrent to the subjects and claims Nussbaum made, so I am pretty sure it was a hatchet job. However, take animal rights, context and situation define a lot of both actions and morals. I would have concerns that Nusbaum was projecting, after all a bear is a bear, and differnt cultures are different. Criteria or argument to make them better or worse, I tend to find suspect. This was a severe problem with early anthropological studies especially with “stone-age” modern cultures.

      • John,

        Reading back the thread for all the open loops.

        I’m not sure how a very general principle evoked by the UN could “tie the hands of policy makers by setting standards that preclude useful tools for success”. As far as I can tell, it tries to construct ethical principles out of actual conventions, upon which better standards could be discussed and contractual matters settled more fairly and squarely. Unless you can show that these principles could not lead to the settlement of successful contractual matters, I believe you are going a bridge too far.

        See for instance what is being said of the PP for international agreements:

        > The PP is frequently introduced in framework conventions. Although this strategy is widely used in international environmental law, it is merely a first step in elaborating more precise rules at the international level fleshing out that principle. Furthermore, in a number of international agreements, the PP is worded in such a way that it is
        deprived of immediate and autonomous applicability. Use of terms such as ‘form a basis for’, ‘inspire’, ‘endeavour’, etc. imply that the principle is merely intended to prepare States to implement their international obligations. Only the repeated use of State practice and consistent opinio juris are likely to transform precaution into a customary norm.

        http://unesdoc.unesco.org/images/0013/001395/139578e.pdf

        This document is not there to present a principle that has decision-theoretic power. This is mainly a conceptual analysis, followed by some issues for applied ethicians. And as BartR said, the definition has no real bite anyway.

      • Yes, the loops are tiresome.

        Your point of a “bridge too far” has merit. However, my POV is from the person designing to meet and implementing regulations. In that case, the exact reading is where to start and how to consider impact when discussing the most likely. Even though it does state that States can do this or that, that requires effort. What professionals have found is what is stated by the authoring group is what you get. In some cases, this is mandatory or must have more restrictive requirements. An example 20% opacity national standard where a state/province could implement 10%, but not 21%. This is most important for definitions and the goals. People, especially politicians are not going to want to re-invent the wheel. Worse, they know each and every item that is changed is a potential landmine from one SIF (single issue fanatic) or another or worse, BOTH! In particular, never ever assume that politicains will go back to rediscuss it, even if it is really bad implementation. An example of this was a rule thought to encourage reconsideration, which basically stated if a quantity in pounds is not formulated, the quantity for reporting is 1 pound. This meant that technically every busted or leaking raditor should have been called into the US National emergency system with resulting investigations, reports, and follow-ups. The emergency system is one of the best ideaas for low probability, dangerous/damaging events, yet was burdened with such a ridiculous requirement that came about trying to make sure problems were not swept under the rug by politicians trying to avoid landmines and SIF’s.

      • John,

        Indeed, it’s important to look at the way how principles get implemented.

        To that effect, I did argue at Lucia’s that the same argument applies to Wegman’s recommendations. Agreeing with these recommendations barely makes sense without agreeing on ways to implement them. My argument was not well-received. Let’s not wonder why.

        Perhaps the same criticism could be put forward the PP. Until we have an idea how to implement it, it has mostly a PR value. I’m not sure it would be as valid as W’s recommendations, for they’re principles. But those who develop an analysis of the PP should be able to warrant the development of more principled regulations.

        Perhaps a bit like constitutional principles. Just an example from the top of my hat: I am no constitutionalist. But I believe you get the idea: the PP serving as some kind of foundation for international rights and duties.

        Another limitation I see is that even if we do get principles and regulations running, we need to have interpretations. With the constitution, you have constitutionalists. Do we have the same kind of specialists for conventions like the Rio Declaration?

      • Willard

        An uncomplicated formula:

        PP = BS

      • Manacker,

        Nice hit and run.

      • Willard if it gets down to the level of implementation it will “have the same kind of specialists for conventions like” other regulations and they will be regulators. The reason I “read” it so strictly is that is what regulators do. They do not , cannot, interpret, that is for lawyers. The regulators read and force /encourage compliance. Judges have a little more leeway, but remember they read strictly as well; they ensure it does not conflict with other law or decisions, or intent of Congress. If it does not, the ruling will be as strict. Some do not know or realize that law as implemented in the US is technical in nature, according to the lawyers who train me.

      • John,

        Thanks to Pooh, I found something that might interest you:

        http://www.bsos.umd.edu/gvpt/lpbr/subpages/reviews/sunstein805.htm

        Perhaps you already know Cass R. Sunstein. I did not. His Wiki page notes that he were a lover of Martha Nussbaum.

        I would tend to trust Martha’s judgement. He seems to be somebody worth studying. And what he says does seem to agree with your own line of thinking. I find that this chapter seems to fit perfectly well our current topic:

        > Chapter Five, “Reconstructing the Precautionary [*638] Principle—and Managing Fear,” emphasizes the importance of identifying the “full universe of relevant risks” (p.122), although, of course, this notion is in tension with his earlier argument that everyone is subject to the biases revealed by cognitive psychology. It is also fair, I believe, to note that if one is at all attracted to chaos theory and “butterfly effects,” then it becomes a combination of utopian and bizarre to suggest that we can ever hope truly to be aware of every risk attached to any particular proposal. One is almost always—the “almost” is really an academic fudge—making important decisions under conditions of uncertainty, as Sunstein well recognizes.

        I’m not sure how one can bury the PP and reconstruct the PP in the same book, but it seems that Sunstein succeeds in doing so.

        All in all, the concept of deliberative democracy is a concept that deserves due diligence.

      • Willard October 12, 2012 at 9:47pm:
        Thank you for the link to the book review (Laws Of Fear….) by Levinson and the Garwoods. I had captured the papers, but not this succinct summary of the book. :-D

      • Thanks Willard. I think I read a brief write up of some of his work but it commented on the critic’s percieved weaknesses in Chs 4 and 6, elitism and the value of life. But that may have been about another author since the assumed valuation of these two properties are often criticized in AGW and environmental arguments. These were reported as “major” issues for the commentator. However, I think you are right, the work is one that would be more along the lines of training and expierence I have had. IIRC, Sunstein was taken to task by some for Bush bashing. I am only sorry I wasn’t the one with such clever and well thought out bashing. I believe it really struck some nerves. I also seem to remember that some of his work was part of the discussion of environmental justice where some UN?/NGO lawyers were claiming that they could make a good case for it legally wrt existing treaties. I can’t remember which way they used Sunstein, but IIRC they used it for support and that is why the critic was pumpng up the percieved weakness of Chs 4 and 6. It was about the time of climategate. Though at this rate of finding good things to read, I might have to give up a hobby or two.

    • John Plodinec

      PS. I’ve been on travel since right after I posted the original comment. I’m glad I’ve provided entertainment for so many, as well as the opportunity to feel superior!

  6. Based on the last hundred years’ experience, should we sit back and observe for another hundred years, or should we sit back and observe for two hundred years before getting our shorts in a twist?

    • I’d settle for 10-15 years with no one telling us we have to act immediately or we’re all dead.

      • Hi Bill,

        I initially agreed, and would still appreciate blessed silence from the alarmist loonies. However …

        It may be that the continuing alarmist blathering, “We’re all going to die”, may cause the public to become inured to the noise, rendering these screamers neutered.

      • and then we all die

      • lolwot,

        besides the simple fact of us all eventually dying, would you care to elaborate how climate is going to kill anyone?

      • lolwot,

        What Gary Turner says makes sense to me.

        Suppose there’s a fire alarm in your building: do you start to scream like a madman and panic?

        I guess not. At least hopefully. That’s the point.

        Cf. The Hitchiker’s Guide to the Galaxy.

      • Gary doesn’t think there’s a fire and hopes that the people screaming about a fire will eventually make everyone in the building stop taking the threat of fires seriously.

      • Latimer Alder

        @lolwot

        So where is the fire? Where’s the smoke and flames?

      • Gary assumes there can’t be a fire. Ever.

        Either that or he wants everyone to die.

      • Latimer Alder

        @lolwot

        Lots and lots and lots of things ‘could’ happen.

        But one is very very dumb to assume that they all ‘will’ happen. Better to use some rational judgement than simply follow the few fantasists who have already succumbed to mindless panic.

        Otherwise, I have this lovely bridge to sell you..only one careful owner.

      • If you talk to a fire marshall, people in a building where there is fire and smoke are usually inclined to ignore the alarm. The real problem is non-alarmism. They wait too long. Then they panic. Then they trample.

        Yelling fire in a theater is unlikely to cause a problem because people will just sit there. They’re enjoying the show. They do want to be bothered, and they want to appear to have cool heads. It’s when the burning curtains fall to the stage that they finally get up and crush one another.

      • Me too, Bill.

        Max

  7. The best question(s) to discuss/debate:
    1. What is the most likely change in average temperature going to be over the next 50 years

    2. What will be the likely change in conditions (positive and negative) in specific countries as a result of the conclusion reached in #1, and what is the evidence to support this conclusion?

    3. Based on the conclusions reached in #1 and # 2, what government policies are suggested for a specific country and why do these policies make sense

    • Latimer Alder

      + LOTS!

      • Thank you. I am starting to wonder if people posting here really like to having substantive exchanges or simply like to post meaningless dribble.

      • A bit of both, the ability to skim quickly through the dross is essential.

      • Rob Starkey,

        I agree. It’s disappointing that intelligent people can spend so much time writing such drivel.

      • Latimer Alder

        It’s both…just like real life.

        The upside is that the barriers to entry into the blogosphere are pretty much zero. This is great, because it allows those who are not full-time employed on climate matters as much of a say as the supposed ‘professionals’. And, for a problem (if it is indeed a problem) that supposedly affects us all, this can only be right. You do not need a DPhil to participate, nor to be affiliated to an institution. Anybody can write about it.

        The downside (if you are a full-time professional) is that your work gets examined in a whole host of different ways by people with a whole host of experiences. A far wider going over than traditional ‘peer-review’ which was well characterised by Phil Jones

        ‘I’ve never requested data/codes to do a review and I don’t think others should either. I do many of my reviews on travel. I have a feel for whether something is wrong – call it intuition’ (CG 2486)’ (*)

        and the discussions do not tart from the assumptions of the ‘climate science community’ that ‘its all going to be far worse then we expected’
        and that ‘more research is needed’

        The price you pay (if indeed it is a price) for this magnificent new tool is that some of the arguments are not presented in the manner of conventional academic discourse. If that offends you too much, then you are of course at liberty to withdraw. But I think you’d be throwing out the baby with the bathwater if you did so. There may be a lot of waste material in the blogosphere but there are also nuggets of gold.

        (*) En passant, am I alone in thinking that the alarmists have been strangely silent on the supposed virtues of ‘peer review’ recently? A couple of years ago they could hardly restrain themselves from shouting ‘Peer Review’ on every occasion as if it was some sort of magical academic talisman. Now, however, it is hardly heard. Perhaps the awful (in very sense) of Gergis et al (hubris in living form) has persuaded them that their golden shield is instead little better than base metal. They really are running out of ideas.

    • “1. What is the most likely change in average temperature going to be over the next 50 years”

      0.5C to 1C warming.

      “2. What will be the likely change in conditions (positive and negative) in specific countries as a result of the conclusion reached in #1, and what is the evidence to support this conclusion?”

      No-one knows.

      “3. Based on the conclusions reached in #1 and # 2, what government policies are suggested for a specific country and why do these policies make sense”

      Given the significance of the warming relative to past climate change coupled with the complexity of the climate system and the possibility of tipping points that cannot be ruled out, the reduction of emissions should be given high priority.

      Countries should come to an international agreement to lock large proportions of existing oil, coal and gas fields and to lock any new discovered ones entirely. Locked resources would be prohibited from being mined until eg 2100 where there would be a reassessment. This would limit carbon emissions and reduce climate change risk.

      • It’s interesting that you only expect 1-2 C of warming during the next 100 years. That’s very little and basically meaningless. I can’t see anything bad from that small an temperature increase. For sure, the warmer climate will definitely be a good thing for Finland, where I reside. It’d boost our agriculture and reduce our heating costs.

        When it comes to policy, it’s pretty much impossible to limit the amounts of oil, gas and coal used unless one comes up with a superior way of replacing them. If the technology is not there, you’ll just make it more expensive, which leads to poverty and environmental damage in poor countries. But when the technology is there, it’ll replace coal, gas and oil without any international agreements. Better technology has a tendency to replace worse ones.

      • You might notice I asked for a 50 year forecast and I did so intentionally because over that timescale infrastructure can be build and it is easier to measure whether or not anything is actually happening.

        Actually he/she only expected .5C to 1C in 50 years, but it would not be appropriate for you to forecast that will doulbe in 100 years. Many “climate scientists” would argue that the rate might change greatly after year 40 and lead to runaway warming in years 51 through 100 that will lead to great disaster for humanity if we do not implement what they think is correct.

      • lolwot,

        I have a hard time coming to the conclusion that we need to take dratic actions to deal with impacts we have no idea of. All you can offer is the concept of complex systems possibly having tipping points.

        Your being afraid of one possible future – and one with little evidence to date of being even remotely likely – is enough to justify condeming tens, if not hundreds of millions of people to death and a few billion to a harsh, difficult and likely short life? For that is exactly what will result if we follow your policy precription above. Sorry lolwot, I’m not biting.

      • Gradually locking up fossil fuel reserves isn’t drastic. It would be a calm and controlled process over decades, with plenty of time to settle in and adapt, even room to change the pace. It’s a scenario that governments can easily plan for.

        In comparison all the bad stuff you imagine from sudden cuts is actually more likely to happen in the event of a climate disaster. Aside from the direct impact, the aftermath of a climate disaster would likely see panic and very strong pressure for an international reduction in emissions.

        Lets say the population of Australia for example are slammed by some kind of climate disaster and suddenly emission reductions are the top priority of every voting Australian. When Australia comes to the international table asking for other countries to cut emissions how do you say no without that effectively being perceived as an act of war (we’ll keep doing what harms you)?

        If you want millions dead, either through war or a dash to cut emissions too quickly, the best plan is to keep blindly emitting as much CO2 as possible and risk climate disaster which will prompt those things.

      • lolwot,

        Since you are convinced that a “climate disaster” is inevitable, despite the fact that no known mechanism has been identified linking a warming climate with any singular weather event, nor even any correlating evidence showing an increase in storm numbers or intensities as we have been warming, what is the point of a rational discussion?

        You simply believe it, without any supporting evidence. That’s called faith and I’m not going to with someone about their religious beliefs, as I believe in freedom of religion.

      • Your very first founding sentence is wrong. I didn’t say a climate disaster was inevitable.

        I warned one is possible.

      • David Springer

        A vastly improved climate is also a possibility. A greater possibility IMO given we’re 10,000 years into an interglacial period where the average length of interglacial periods isn’t much more than 10,000 years. And given how poorly food crops grow in snow and ice and how many people can’t feed themselves by hunting woolly mammoths. You may hold a different opinion of couse but it would be an opinion that is ultimately misguided and harmful.

      • OK,

        I’ll stand corrected. Perhaps this is a better summary – it is inevitable unless we make dramatic (or significant, if you don’t agree with the term dramatic) changes to how we utilize current energy and natural resources.

      • “1. What is the most likely change in average temperature going to be over the next 50 years”

        0.5C to 1C warming.”

        I sort of agree with lolwot.
        I was going to say the most warming anyone could expect is 1 C.
        And mostly likely would be .5 C or less.

        ““2. What will be the likely change in conditions (positive and negative) in specific countries as a result of the conclusion reached in #1, and what is the evidence to support this conclusion?”

        No-one knows. ”
        This seems the whole point of question #1 and only thing of interest to policy makers- the entire relevance of everything and anything to do with studies of global climate [which is different than the subject of climate and/or weather].
        And once again, I sort of agree with lolwot: “No-one knows.”
        But the effect on humans to at least .5 C will be essentially continuation
        of the same effect on humans over the last century.
        And if it closely approaches 1 C in warming, the public will regard the CAGWer as having some merit to their expressed concern. The public and the pols could do something very stupid.
        To get to 1 C of warming within 50 years, will require some significant warming within the next 10 years. And so will allow most people see the possibility of 1 C in 50 year as likely. So it will not take 50 years before policy acts. Or if we continue roughlly at rate of present warming for next 10 years, then at some point towards the 50 year point we need an rate increasing which is even more severe. Or quite simply, we need to see more warming that occurred over last century within a period of 40 years.
        And if are right that we will see some cooling over next couple decade, basically temperature would need go straight up- and similar to Space Aliens showing up. Both of which are not very likely.
        So, to get to 1 C, we need significant warming in next 10 years.
        Though getting to the peak 1998 temperature within 50 year do not *require* much warming in the next 10 years, a couple decades of cooling could even result in peaking to this level in within 50 years. And that would .5 or less warming.

        The effect on the environment of 1 C rise in 50 years, will be about as unnoticeable as the warming of 20th century. No polar bears will die as a result. Though a 1 C rise in global temperature may not tell us anything about global climate- temperature is not really something which effect humans or life, whereas patterns rainfall, would be more relevant than average global temperature. But such continuation of warming should have more effect on frostline and tree lines. Trees may being to grow where once they couldn’t.

      • randomengineer

        Utter drivel. Unless there’s a plan to control global emissions (i.e. you can force the chinese and indians and such to comply) then emission control strategies are indistinguishable from penalising the western economic sphere with no gain possible.

        Even if such a plan could be implemented (it can’t) then even in the US there’s enough anti-governmental growth sentiment that such a plan would be politically impossible. Bear in mind that the purpose of the bill of rights is to protect the citizen from the government, and lots of Americans view government growth and socialist 5 year emissions plans very poorly.

        In what we like to call the real world, the one we all live in, what is likely the only reasonable solution involves harnessing solar from space (eminently do-able) to provide jobs and growth; this would be augmented with advanced nuclear technologies like thorium. Energy and wealth are the same thing. These things would happen for their own reasons and of their own accord; emissions reductions are simply a happy (for you) byproduct and not the goal.

        There is no goal of emission reduction that works or can or will work in this lifetime, and only overeducated putzes are stupid enough to think such a thing is even possible.

      • Dr. Curry, could you pass ‘randomengineer’ my home email address and ask him to contact me about this:

        “In what we like to call the real world, the one we all live in, what is likely the only reasonable solution involves harnessing solar from space (eminently do-able) to provide jobs and growth; this would be augmented with advanced nuclear technologies like thorium. Energy and wealth are the same thing. These things would happen for their own reasons and of their own accord; emissions reductions are simply a happy (for you) byproduct and not the goal.”

        and ask him if he would like to discuss it away from the Climate Change environment?

        If he is not interested, that is fine too.

        Thanks.

      • lolwot

        You have just contradicted yourself.

        You forecast 0.5C to 1.0C warming until 2050. This equals an average warming rate of between +0.123 to +0.246C per decade

        Then you write:

        Given the significance of the warming relative to past climate change coupled with the complexity of the climate system and the possibility of tipping points that cannot be ruled out, the reduction of emissions should be given high priority.

        No doubt the “climate system is complex”, but the warming you forecast is not at all unusual “relative to past climate change”. It is only sightly higher than the short-term warming rate of the 1990s.

        There is absolutely no logical indication of any anthropogenic “tipping points”, although sudden natural climate change can never be ruled out, as the Chief has reminded us (but, then again, there is nothing we can do about that).

        Therefore, there is no logical reason to “give high priority to the reduction of emissions”.

        Now let’s look at your assumed future warming rate.

        First of all, at +0.184C+/- 0.0.62C it is slightly lower on average than the IPCC forecast of +0.2C per decade (AR4), and even lower than the earlier (TAR) forecast of +0.225C+/-0.075C. So your trend appears to be in the right direction..

        The 21st century trend so far has been cooling at -0.063C per decade.

        The long-term underlying warming trend as we have emerged from the LIA has been around +0.05C per decade.

        I would guess that this long-term trend will continue and that you have exaggerated the future warming by three times on average, and that we will only see around 0.24C warming until 2050. (But that’s only my guess, which isn’t any better or worse than your guess.)

        At any rate, you have demonstrated that there is nothing that requires immediate action on emissions.

        Thanks. (I’m relieved.)

      • lolwot: “0.5C to 1C warming” over 50 years? Then there is no problem.

        Back in late September, I gave you some examples of the effect of 1C increase. The differences in average temperature are:
        – For Boston, MA vs New York City the difference is 3F, or 1.7 times the 1C heating for low CO2 doubling and 2.5 times the 1.5 C heating for high CO2 doubling.
        – For Boston, MA vs Washington, DC the difference is 6F, or 3.3 times the 1C heating for low CO2 doubling and 2.5 times the 5 C heating for high CO2 doubling.
        – For New York City vs Miami, FL the difference is 21.8F, or 11.8 times the 1C heating for low CO2 doubling and 17.7 times the 1.5 C heating for high CO2 doubling.

    • Rob Starkey,

      Excellent comment. Judith asked for a response to her question in the context of the US presidential election. I believe that is an important and relevant constrain on the question. So I interpret it as “what could the US President do to assist the world to reduce global greenhouse gas emissions? I have a suggestion, I’ll post at the end of the thread.

  8. I don’t think “some warming” has any meaning. “Some” may be unmeasurable. You can have “some” CO2 warming with a general cooling.

  9. What’s the best climate question to debate?

    IMHO:

    Is “climate change science” mature enough to get alarmed by his statements?

    • randomengineer

      I’d go with —

      “how do you force the chinese and the indians — 1/2 of the world’s population — to play the game you want them to play?”

      If you can’t get the planet on the same page it ain’t happening.

      • Random Engineer,

        You can’t force them. But you can make it to their benefit to reduce emissions. The way to do this is to give them a cost competitive alternative to fossil fuels. The USA could lead the way on that. I’ll post more in a separate comment at the end of this thread.

    Indeed Evoquing the Precautionary Principle is a good question. A beautiful example of the “boomerang effect” that even “non scientifically educated” political decision makers must understand. Another good one, addressed to manistream self procamed gourous scientists (?) could relate to the opportunity of using “spatio-temporal averaged temperature anomalies” for estimating possible slight changes in a very complex ENERGY system exhibiting a huge number of delayed negative feedbacks (Is this the right indicator to use?). Also the importance of (temperature) measurement errors on the long term predictibility of non linear time series (=temperature records and proxies) seems to be key to me for an eventual validation of any predicitve model. This last point, more mathematical, relates to the detection of a chaotic signature in time series, by calculating e;g. the corresponding Liapounov exponents or Hurst coefficients. This isa mathematical definitively strong argument, but however difficult to explain to non specialists. So, I make three propositions, according to who the audience would be.

    • David Springer

      Neutron stars are not possible with mass less than 1.38 solar masses due to insufficient gravitational force to overcome neutron repulsion. This is known as the The Chandrasekhar Limit. How would it then be possible for Sol to have a neutron star (pulsar) at its core when its mass is well below the Chandraskhar Limit?

      • David Springer

        They say silence is golden. It’s also revealing in cases like these. :-)

        http://en.wikipedia.org/wiki/Chandrasekhar_limit

        It appears in the 30 years since I took Astronomy 101 in college the limit has been raised from the original 1.38 solar masses Chandresekhar proposed in 1930 to 1.44 solar masses today. My apologies. Of course that makes OManual’s problem in explaining a pulsar with <1.0 solar masses a little bit harder.

  13. My idea for the best subjec t to debate is

    Should the world commit economic suicide by reducing our consumption of cheap fossil fuels on the basis of the hypothesis of CAGW, when we know that there is absolutely no empirical data whatsoever to support this hypothesis?

    • I second Jim Cripwell’s suggestion. It appears to be the “question of the day”.

        You know that, I know that, and about half the denizens of Climate Ete. know that. But there are a lot of very important people who DONT seem to know that. Let me list a few

        1. Our hostess. Or at least she might know it, but she wont admit it.
        2. My MP, David McGuinty. He is a potemtial candidate for the leadership of our Liberal Party in Canada, and although it is a long shot, a future Prime Minister of Canada.
        3. The people in charge of most of the scientific learned societies all over the world; headed by the Royal Society, the American Physical Society, and the American Meteorological Society.
        4. The political leaders of most of the G8 countries, whose countries have a large proportion of the world’s wealth. Though is fairness, some of them, particularly in the UK, seem to be starting to realize the truth of the matter.

        I could go on, but I hope people, particularly our hostess, see what I am getting at. So, although the answer is clearly no, as you state, the issue is still wothwhile debating, so that we can prove beyond resonable dounbt, that the answer is no, and thereby convince some VIPs that the answer is no

      Jim you forgot to mention the obvious alternative of all of us filling our cars with unicorn farts. Without a viable alternative in place there is no reason to even bother discussing climate crap. It’s moot.

    • Jim Cripwell,

      I agree. However, it is apparent that the ‘warmists’ do not appreciate the economic damage that their policies would do. The ‘warmists’ apparently do not appreciate the effect the mitigation policies would have on human well being. But I do not know how we can make contact with ‘warmists’ on this subject. They dismiss it and do not want to engage.

      Are there any warmists prepared to engage in seriously discussing the economic consequences of the carbon pricing and mandatory renewable energy policies they promote as the solution to ‘greenhouse driven global warming’?

      • Peter Lang,

        “Are there any warmists prepared to engage…” You probably would call me a warmist but ………..

        Anyway I’ll help out with a catchy name suggestion for your theory. How about:

        “A stitch in time costs nine” ?

      • “the economic consequences of the carbon pricing and mandatory renewable energy policies ”

        Forget the economic consequences. What will be the emission reductions acheived by such policies ? Nill.

    • Do some real systems analysis. Systems analysis is doing both climate science and fossil fuel projections. In simple terms, the system is the thing you draw the circle around. Some find the combination valuable ; however YMMV.

      Here are some recent analyses that shed light on the numbers being bandied about:

      • Steven, so really none of this is of any relevance then is it? Nothing from Governor Houses from around the world. HMS XXXXXX… all of that stuff and more would fit in a trunk you think?

      • Steven Mosher

        It is simply of no relevance. It’s of no relevance because

        1. The data still exists at NWS.
        2. Jones added no value to this data.
        3. You get the same answer without “his” data

      • Willis Eschenbach

        Steven Mosher | October 8, 2012 at 11:13 am

        he had nothing of relevance. basically a small number of records from NWS. As detailed in the mails he thought he could get the data again but that it would be a PITA. This is a NON issu[e].

        The big problem wasn’t that he had only a small number of records and had lost the rest … although assuredly the guardian of the records losing the records is indeed a problem.

        The larger problem was that he was (and still appears to be ) willing to lie and cheat to keep anyone from finding out that he had lost the records. Not only that, but his friends were willing to lie and cheat to cover up Jones’s sins of omission and commission.

        Finally, when it was all revealed, almost no mainstream climate scientists had the balls to comment on those transgressions. Instead they were all off pondering crucial questions like “How about those Yankees, you think they’ll win the pennant?”.

        And those, my dear Steven, are HUGE issues that have led to the deserved discrediting of an entire branch of science … a discrediting that will be extremely difficult to repair.

        In a speech at Clinton, Illinois on September 8, 1854, Abraham Lincoln said:

        If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem.

        So you might as well not bother telling us that the damage done by Jones and his actions were a NON issue, Lincoln saw that BS coming a century ago.

        w.

      • Willis, Do you know of some manifest that would show just what was received by CRU? There must be some document that would have logged the records sent to UEA/CRU. Even if the books have been burned; there should be an inventory still available. It would be a very interesting read.

      • …”although assuredly the guardian of the records losing the records is indeed a problem.”

        Willis, PJ threw the records out on purpose to ‘save space’. Even a bigger problem, to me.

      • Steven Mosher

        How do you know when Willis has no argument?
        He cites lincoln.

        1. Jones got 98% of his Monthly data from GHCN.
        2. The source data he got directly from NWS, was not kept after
        their “value added processing” but Jones thought he could
        reconstruct/re request this data if required.
        3. If you take all 36K+ temperature records and remove those that CRU uses, and compute the global average you get the same damn answer.

        He lost data that others gave him. Like So: I give you data, and you lose it. But I still have it, so the data is not “lost”. I might call you absent minded or sloppy if you lost data I gave you Willis, But I would not cite Lincoln.

        It’s Scientifically un interesting. Which explains why you must bloviate.

        Let’s put it in perspective. Lucia lost a hard drive and some mails. Nobody gives her grief. I’ve misplaced a bunch of papers and data over the last 5 years. Nobody gives me grief. Jones misplaced data or failed to preserve data that others gave to him. And you want to crucify him.

        There is a concept called proportionality. Your emotions are out of proportion to this situation so you are either grandstanding because you have no real argument and pounding your shoe on the lecturn or you are too attached to the Jones issue.

        He lost his copies of other peoples data. Nothing scientific changes. The data still exists. The same answer is derived with independent data. So, the reason why you are upset, must be you.

      • “he had nothing of relevance”

        Then, why did he lie about it?
        When asked for the data he should have replied “sorry chaps, I lost it” and that’s that.

        it might not be scientifically relevant, but it’s relevant from other aspects.

  15. “While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear.”

    Assuming that greenhouse-driven global warming is the most significant impact in the long term would require a definition of the long term.
    Over the past 300 years an area the size of the continent of South America has been converted to plowed land. In addition, twice the area of South America has been converted to “agricultural” land. “Peak” land use, which impacts the carbon cycle, occurred before the estimate “peak” oil and is a more pressing issue in the long term than peak CO2. CO2 could well be a “tracer” gas of issues instead of a cause of the issues in the long term.

    ” What do you see as the best mix of achievable policies to limit environmental and economic regrets?” Polices that deal with the largest number of potential issues in the long term.

    • Any question which states that “the long-term picture of a profoundly changed Earth is clear” is not worthy of consideration.

  16. If you can’t explain “ordinary” in climate, how can you even ask the question?

  17. I do not think the West has the moral authority to withhold the economic and societal benefits offered by plentiful and cheap carbon-based fuels to the Third World. More affluent societies have lower birth rates which go a long way in reducing pollution, greenhouse gases, and the drain on natural resources. Therefore, I would not limit the use of carbon-based fuels in any way, other than to reduce particulate pollution and elemental pollution (but not with the intent to close down “unsuitable” carbon-based energy sources like coal, as this Administration is doing).

    • I agree 100%. If the rich countries what to help the world cut greenhouse emissions, the rich countries should develop a cost effective substitute for fossil fuels that is appropriate to be used all over the world.

    • Peter Lang,

      “….the rich countries should develop a cost effective substitute for fossil fuels

      Isn’t that the point of putting a price on carbon emissions? There are cheaper solutions if the cost of emissions is properly factored in.

  18. johnfpittman

    The best question “What would it take for humanity to address a real “failure of the commons?”” Until this is resolved satisfactorily, answering “”What do you see as the best mix of achievable policies to limit environmental and economic regrets?””
    is not answerable. This is based on the assumption that BAU will not work. If one assumes BAU will work, then there will be little or no oppurtunity to do better than is already likely to happen.

      • Steven Mosher

        Nice convo you had with BBD. Looks like you had some upside down data… capsized.

    • Johnfpittman,

      “What would it take for humanity to address a real “failure of the commons?””

      No, that is a pointless question. It has an underlying premise that is not accepted by many. The premise is that climate change is catastrophic. The evidence for that is weak.

      • I did not state that CC is catastrophic, nor is it necessary for such that a failure of the commons should be addressed. CAGW does not and I did not claim it was the only failure of the commons. Your conclusion of my premise is incorrect. But I will state in terms of CC, if true, one still needs a good way to addresss this failure.

      • Communism has been tried and failed – at every attempt.

      • Peter, I am not and have not been advocating communism. That is one of the reasons that a real conversation needs to occur. Otherwise, if only a communist government can comply, the likelihood of having an agreement by the US is unlikely and, besides, historically, the worst polluters have been autocratic states and the poor. A combination of both would be both a human and an environmental diaster based on autocratic government’s track record.

  19. What’s the best climate question to debate?

    Should politicians continue spending billions of tax payer dollars to subsidize a political movement disguised as science?

    Should we :

    Defund the IPCC;

    Defund the unending stream of “research” grant applications that seek to cash in on the current apocalyptic fad;

    Defund the EPA’s attempt to decarbonize the economy by fiat.

  20. Tomas Milanovic

    I have always had difficulty with questions which stealthily already contain the answer.

    For instance asking “What minimal (no regret etc) action must be done in order to …” implies without necessarily demonstrating it that the answer can’t possibly be “No specific action at all.”
    Symmetrically asking “What minimal observation (proof etc) must be done in order to contemplate actions to ….” implies without necessarily demonstrating it that the answer can’t possibly be “We should do X anyway”.

    That’s why the answer depends on the way the question is formulated and the debates about these formulations (which are made more obscure by the evocation of an even more obscure precaution “principle”) can and will go on forever.

    My personal position has always been the same for the last 10 years.
    First I ask when is predicted the next Ice Age .
    Second I ask whether a transitory during 1-2 centuries will cause the next Ice Age to occur rather sooner or rather later and if a translation, is predicted, by how much.
    As long as I have not a well argumented answer on these 2 questions, I consider the climate dynamics just as an academical and interesting exercice with few and far between well understood domains.

    That’s why there is no specific action for limiting CO2 that would interest me, especially then not if it should have a significant cost.
    Likely obvious for me is the fact that actions leading to energy and matter savings have always been important and interesting regardless whether their byproduct is decreasing CO2 (majority of cases) or increasing CO2 (minority of cases).

    • This reinforces my earlier reply that any question which states that “the long-term picture of a profoundly changed Earth is clear” is not worthy of a response.

  21. Judith Curry

    Andy Revkin tells us:

    While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear. What do you see as the best mix of achievable policies to limit environmental and economic regrets?

    The first phrase is undoubtedly correct, i.e. ”persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming”

    You have argued this point very effectively in the past. There is too much uncertainty in climate attribution to claim, as IPCC does, that most of the past warming was with 90+% likelihood caused by increased human GHG concentrations.

    From this uncertainty in the attribution of past warming it follows that the IPCC projections of future warming and its impacts are even more “uncertain”.

    The next phrase is purely presumptive on Revkin’s part, ”the long-term picture of a profoundly changed Earth is clear”.

    While it is highly likely that our climate will continue to change, as it has over past centuries, it is NOT at all clear that there will be a “profoundly changed Earth”; it is even LESS clear how this “profoundly changed Earth” will look. So Revkin has tossed out a strawman.

    The rest of his paragraph is based on the validity of his “profoundly changed Earth” strawman.

    It makes a further (unstated) leap of faith that we humans are causing this posited “profoundly changed Earth” and an even further one that we could do something about it if we wanted to.

    There is no “best mix of achievable policies to limit environmental and economic regrets”. [Maybe the best would be to abandon the IPCC?]

    Revkin should realize that it is silly to even talk about these until the “deep uncertainty” surrounding human attribution of past climate change can be cleared up enabling scientists to reliably forecast whether or not there will be significant human-caused future changes and how these will look.

    So what’s there to debate?

    NOT how to solve the imagined future problem as Revkin proposes.

    Instead we should debate whether or not we have a future problem at all.

    Max

  22. “While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear”

    How long are we going to put up with garbage like the above? “The long term picture of a profoundly changed Earth” is a nonsense. We’ve seen it all before, and will see it all again.

  23. “What’s the best climate question to debate?”

    When will climate scientists clean up their act?

  24. Further to my earlier post, it is apparent that Revkin wants to redefine (or by-pass) the global warming decision process.

    • A gigantic baksheeshing the question. And we’re begged to come up with a question. It seems so backward, but ignorant we are.
      =============

  25. …What do you see as the best mix of achievable policies to limit environmental and economic regrets?

    Is that, speaking as an average New Yorker, American, Westerner, Hollywood personality, UN delegate, historian, George Obama and Joe the Plumber, an egalitarian communitarian or a scientific literate skilled in numeracy with respect for the teachings of the scientific method as a means of separating truth from fiction?

    • Wagathon,

      or a scientific literate skilled in numeracy with respect for the teachings of the scientific method as a means of separating truth from fiction?

      The scientists have a contribution to make. But they lack others skills that are needed for informing policy decisions. Their lack of understanding of the other essential skills has been demonstrated repeatedly by the alarmists (including the advocacy climate scientists) who post on Climate Etc.

      • Absent respect for the teachings of the scientific method all we’re left with is the casting of chicken bones and the ancient science of astrology to overcome superstition and ignorance through knowledge.

  26. I am not sure at this point how to word such a question, but some guidelines that I might work from in formulating the question include:

    1.) Clearly the ‘what’ and the ‘how’ to ask are informed by the context/forum in which the question is advanced. For example, the question may be more revealing in a setting such as the first debate and useful than in the upcoming town-meeting format which is probably going to draw out time-limited pre-canned answers.

    2.) If it is highly likely that the candidate will answer to a ‘constituency’, then the answer is worthless and there is no need for the question to begin with. (I regret that this is this is highly likely.)

    3.) Canned answers are useless. One objective I would have would be to phrase any question in a manner that reveals something about the ‘real’ state of the candidate thoughts. Can the question be devised to provoke a degree of spontaneity? (Probably not.)

    4.) I might consider something like the following: Given the current state of the climate change debate,and given that we can not jump into a time-machine machine and reset history, what are the present alternative approaches—no action, staged response alternatives, all out response, etc? What do you see as the upsides and downsides to each alternative? The preceding may be sloppy phrasing on my part, but the idea is to probe the candidates’ views and understanding of the overall problem incorporating the component political, technical, societal, and economic contexts. How well can the candidates’ define the problem without pandering to a constituency. In the question I would avoid explicit reference to the precautionary principle—it is too much of a pre-wrapped bias (as a crutch or as a club) to hand a candidate. If a response uses it fine—that may provide insight about the candidate. In asking the question I would also not explicitly ask for selection of an alternative—let the candidate reveal that if he is so inclined.

    • I can tell you right now. One candidate believes the science is settled and the policy course is clear. The other is less certain.
      =============

      • kim

        I could careless about what the candidates’ beliefs on the science are. That is only a component of what the question (if possible to formulate) would seek. I want to probe the candidates understanding of the BIG issue, to wit:

        “the idea is to probe the candidates’ views and understanding of the overall problem incorporating the component political, technical, societal, and economic contexts. “

  27. Climate question: Can we fuel economic growth and control climate?
    When mitigating anthropogenic global warming is projected to require greater than 80% lower fossil energy use, how do we provide the transport fuel and energy for rapid growth by developing countries while sustaining OECD economic growth when the Available Net Exports of crude oil – after China and India’s imports – have already declined 13% since 2005, and Saudi Arabia may need to import oil by 2030?

    Jeffrey Brown observes:

    We define available net exports (or ANE) as GNE less China and India’s combined net oil imports.  ANE fell from 40 mbpd in 2005 to 35 mbpd in 2011 as the developing countries, led by China and India, consumed an increasing share of a declining volume of GNE. 

    See graph at: An update on global net oil exports: Is it midnight on the Titanic?

    Gail Tvedberg at Our Finte World documents a very close connection between Energy consumption, employment and recession

    Since 1982, the number of people employed in the United States has tended to move in a similar pattern to the amount of energy consumed. When one increases (or decreases), the other tends to increase (or decrease). In numerical terms, R2 = .98.

      David,
      That is an amazing question.
      What technologies do we have to control climate in the first place?

      • David Springer

        Aerosols from unfiltered coal-burning Chinese power plant smokestacks seems to be a smashingly good technology to battle global warming. At least the usual suspects think so since they’re blaming the lack of warming for the past 15 years on it as well as the lack of warming from 1940 to 1980. Unfortunately they haven’t come up with a good reason for the Little Ice Age yet since very few unfiltered coal-burning Chinese power plant smokestacks were extant circa 1650AD. :-)

        The primary issue is still how to we ensure growth and avoid economic collapse for failure to provide sufficient transport fuels.

        Re: technologies to “control climate”
        Numerous authors posit options
        First, should we mitigate or adapt?
        To date I have not seen a financially sane basis to “mitigate” global warming, only to “adapt”. cf Monckton “As they say on the London insurance market, ‘When the premium exceeds the cost of the risk, don’t insure.’”

        Is “climate control” possible?
        Chemical engineering expert Pierre R. Latour waxes eloquent
        Engineering Earth’s thermostat with CO2?
        Chemical engineer takes on global warming.
        To control a system, Latour notes it must be measurable, observable, controllable, stable and robust. He explores how conventional wisdom on controlling anthropogenic global warming does not meet any of these requirements, let alone all of them.

        Avoid glaciation
        I have seen very little discussion addressing the far greater problem of what we do to ensure that we do not descend into the next glaciation.

    • David L. Hagen

      Bigger question: Can we avoid another glaciation?
      See: Onset of the next glaciation

      • The Skeptical Warmist (aka R. Gates)

        Most optimistically we’ve simply forestalled the next glaciation.

        Most pessimistically, we put enough carbon into atmosphere to trigger a massive methane release set to begin any year now.

        The truth is somewhere between these two extremes. Finding it is what the game is all about.

      • David L. Hagen

        The Skeptical Warmist
        I am very skeptical that you are actually sufficiently skeptical!
        Your optimistic wish gives no evidence or validated models to rely on.
        Your pessimistic projection still gives no evidence that that will happen or that it will be enough.
        See Tsedakis et al. (2012) Can we predict the duration of an interglacial?
        But with published estimates of climate sensitivity varying by an order of magnitude, I don’t see how we can rely on their projections.
        We need verified and validated models backed by solid evidence, not wishful thinking.
        Advancing glaciers would very thoroughly erase Chicago while higher CO2 with warming would improve agricultural production in America’s breadbasket. That is a huge difference and we need clear valid methods to chart our way through.
        Restore the integrity of climate science as well as rhetoric!

      • The Skeptical Warmist (aka R. Gates)

        David,

        I don’t disagree. I merely pointed out that the truth lies somewhere between. The science is in determining where the most likely point is and the policy rests in responding to most likely scenarios.

  28. Judith Curry

    As you can see, there appears to be a flood of posts questioning the very basis of Revkin’s (loaded) question.

    You write:

    For the moment, accept that there is ‘some’ warming that is attributable to CO2 (i.e. lets not debate the fundamental science here, but uncertainty assessments are ok).

    Let’s follow your logic.

    “Some warming that is attributable to CO2” can be roughly estimated based on the past record (from 1850).

    We see that this gets us to somewhere between 0.35 and 0.65 deg C for a CO2 increase from 290 to 390 ppmv, depending on whose estimate we accept for the % forcing from CO2 (IPCC at 93%, several independent solar studies at 50%, both based on the IPCC assumption that all other anthropogenic forcing factors cancelled one another out).

    This translates to a 2xCO2 temperature response based on physically observed data of between 0.8C and 1.5C or let’s say 1.15C+/-0.35C.

    On this basis (and with CO2 continuing to rise at the same exponential rate as now to 600 ppmv by 2100) we might see CO2-caused global warming of 0.5 to 1.0C above today’s temperature.

    This is certainly nothing to worry about, so there should be no argument about “what to do about it?”, but rather to reduce the “uncertainty: “could it be substantially more than 1.0C?” and “if so, how much more and on what scientific basis?”.

    IMO these would be the primary arguments.

    The secondary arguments to debate are those listed by Jim Cripwell.

    Just my opinion.

  31. Climate Weenie

    “the long-term picture of a profoundly changed Earth is clear.”
    “limit environmental and economic regrets?”

    The best question to debate is – Specifically what are we worried about?

    That is to say the ‘problem’ is not identified or bounded.

    “profoundly changed Earth” and “environmental and economic regrets” are not scientific terms, not quantifiable, and just fuzzy nonsense.

    The unquestioned assumption is that beyond the probability that GHGs will increase the heat content of earth, there is a net negative impact on humans and/or other ecosystems. But that negative impact is not specified!

    We know that there are benefits to fossil fuel use. Those benefits start with the energy use itself in a useful manner with developed infrastructure which supports it. Beyond that, plant growth and crop yield increase with increased CO2. There are no carbohydrates without carbon dioxide. Plant drought tolerance increases with increased CO2 because of stomatal response. These features are ubiquitous in the literature. We know that precipitation is nature’s desalinization plant and precipitation is modeled to increase with a warmer world. We know that increased growing season and the range of agriculture might be expected to increase. We know that home heating energy use exceeds home cooling energy use, on average, so a warmer world might mean decreased energy consumption. We know that many diseases are limited by heat – including influenza and a significant number of digestive diseases ( heat breaks down virus phospho-lipid shells ). That’s probably a big reason why human mortality peaks in the cold season and troughs in the warm season. We know that human civilization, at least as measured by the ‘cradle of civilization’ occurred during the warmth ( indeed longer, hotter summers and colder winters ) of the Holocene Climatic Optimum. Earlier than that, we know that human migration out of Africa and population were set back during glacials and advanced during stadials.

    These benefits are known, it is the detriments which are weakly identified.
    What -specifically- and measurably are we worried about? Sea level which is rising at about the same rate it has for more than a century? Slowly rising temperature which, given global economic trouble, will have a hard time sustaining?

      • It’s good that climate scientists are using tax dollars to do research, as it keeps them off the streets!

        Points awarded for resigned rationalization over a negative outcome. See, even I can play that game!

        The rationalizations are endless and on the level of a 5-year-old saying that he doesn’t want to do something, just because!

        If it’s warming, that’s a good thing, because it’s good for plants!

        If it’s warming, even better, because it will protect us from an ice age!

        If the arctic sea ice is decreasing, lucky us, because now we can travel from Canada to Russia by a shortcut!

        If the arctic sea ice is decreasing, even better, because now we can start drilling for oil way up north!

        If CO2 is increasing, that’s OK because there is an upper limit to how much hydrocarbons that humans can burn! (but natural variability in temperature has no upper bound, apparently).

        OK, so fossil fuel resources are limited, but renewable energy sources such as wind turbines do not work, and will never work because the people that are interested in it are greens, but they are hypocrites, as wind turbines kill birds, make noise, shed ice, blot the landscape, and parts can fall off and land on somebody’s head!

        The climate scientists are wrong, and if they were right, it wouldn’t matter, because they write nasty emails!

        If the climate does change, that’s OK, because I will be long gone by then!

      • “If the climate does change…”

        It will change, 100% certain.

      • Climate Weenie

        So, you can’t answer specifically what the problem is either.

      • Nice rant WEB,

        You even got a couple of things right.

        Now, care to flip over the disk and play the other side? The one with the rationalizations for why we need to act now to combat climate change.

        Let me help you get started:

        As the climate changes we will be over run with refugees fleeing its impacts.

        As climate changes nations and populations will go to war.

        As the climate changes coastal cities will be swamped.

        If we don’t act now tropical dieseases will spread.

        If we don’t act now we will see extreme mega weather events.

        Climate change will turn the oceans to acid, make the birds fall from the skies, make frogs smaller, forests disappear and cause our teeth to rot and fall out.

        Care to point out one here that is not a rationalization?

    The first question worth debating is whether or not there is a climate crisis that demands trillions of dollars and radical changes in industry.
    The second question worth debating is whether or not emphasizing on mitigation has any added value over emphasizing adaptation.
    Neither of these have been settled, no matter how much AGW proponents claim otherwise.

      > This [What do you see as the best mix of achievable policies to limit environmental and economic regrets?] is a very good question to ponder, its at the heart of the climate policy debate.

        willard,
        I am not so certain that I disagree with Dr. Curry. There will likely be a mixture of solutions. That does, however, beg the question: whatis the scope of the proplem, if there is one at all.
        Right now the AGW community is demanding we spend trillions on a problem that appears to be in the billions or less.
        And could be better addressed by way of focusing on cleaning up energy sources.
        Not one mitigation strategy apepars to be either feasible, potentially successfully and not even close to economically sensible.

        Depends who is doing the considering. There appears to be a small but way too influential eco-zealot constituency for whom wasting other people’s money is an irrelevant concern, so long as they get somebody else to pay for their latest impractical, uneconomic and unworkable scheme.

        Sorry to budge in and to mistake the propre “reply” button.

      • Latimer Adler,

        It might be a bit unfair to burden WebHubTelescope with the task of meeting your demands. He simply seems to say that I might not be as gnomic as you try to portray. Or that he can get most of what I’m trying to say. Or something like that. I don’t mind much to stand corrected on this: this interpretation satisfies me enough not to bother asking him.

        You have no idea how much understanding people can get from others’ words when they put their charity into it. Some cultural background can also help. For instance, by speaking of “charity”, I am gnomically referring to the principle of charity:

        http://en.wikipedia.org/wiki/Principle_of_charity

        Speaking of charity, here’s the link to the Concluding Remarks of the chapter you’re supposed to have read:

        > This chapter has assessed how processes related to vegetation dynamics, carbon exchanges, gas-phase chemistry and aerosol microphysics could affect the climate system. These processes, however, cannot be considered in isolation because of the potential interactions that exist between them. Air quality and climate change, for example, are intimately coupled (Dentener et al., 2006). Brasseur and Roeckner (2005) estimate that the hypothetical removal from the atmosphere of the entire burden of anthropogenic sulphate aerosol particles (in an effort to improve air quality) would produce a rather immediate increase of about 0.8°C in the globally averaged temperature, with geographical patterns that bear a resemblance to the temperature changes found in greenhouse gas scenario experiments (Figure 7.24). Thus, environmental strategies aimed at maintaining ‘global warming’ below a prescribed threshold must therefore account not only for CO2 emissions but also for measures implemented to improve air quality.

        The emphasized sentence seems to run across one of the desiderata you expressed elsewhere. No, I’m not quoting it for now. I want you to ask for it. As I’m not including the quotes related to models: you will have to go fish them out all by yourself.

        I have the impression you don’t realize that when I write a comment, I am entertaining how you could respond. That helps me leave you with some options.

        How do I do it, you may ask?

        By using the charity principle.

      • The emphasized sentence should be:

        > These processes, however, cannot be considered in isolation because of the potential interactions that exist between them.

      • Willard, should I also look at Nussbaum wrt Sen?

      • John,

        I have a friend who did his thesis on Nussbaum. A sexy lady, and truth is sexy. But this is only if you like morality. And even then, I get the feeling you’d rather prefer a consequentialist like Philip Pettit:

        http://www.princeton.edu/~ppettit/

        In any case, my advice would be that if you wish to read anything, first look first at Herbert Gintis’ Amazon Reviews:

        ‘epistemology, philosophy of science, informal logic, philosophy of language, communication theory, and fallacy theory’ at the same time.

        I’ll just collect my cap from the Servant’s Hall and slink off back to my hovel while you drink the port and brandy. And I’ll tell my pals in the Dog and Duck that I’ve met some of the greatest intellectuals of the day..at least that’s what they’d like me to think.

        ‘So what were they like Lattie?’ one of my chums will ask.

        ‘Dunno – couldn’t understand a word they said. But they were ever so pleased with themselves about how clever they were in saying it’

        ‘Did they tell you why they think the world is going to end three weeks come next Michaelmas widdershins?’ says Joe Sixpack.

        ‘I don’t know….they might have, but they were so hard to follow I lost track. One of them with the silly name said something about getting oiled enough…I thought he just wanted another drink, but maybe he meant something else’

        ‘So they didn’t really tell you?’ chimes in Stirling English

        ‘Nope. You’d think that if they really had something to say they’d be able to do it clearly and simply. But they don’t. I think they just like playing intellectual games’

        ‘So what they say is all a load of old bollocks then?’ remarks Woody the Barman.

        ‘Seems like it. And I don’t think its worth wasting much more time on them. If we’re all threatened with going to die in Thermageddon, it’ll be better to talk to people who do know what they’re on about. This pair of chumps don’t’

        So, for now, we have seen the Executive Summary, the Introduction, and the Concluding Remarks of Chapter 7: Couplings Between Changes in the Climate System and Biogeochemistry.

        Here is a quote from section 7.1., entitled Ocean Ecosystems and Climate

        > The functioning of ocean ecosystems depends strongly on climatic conditions including near-surface density stratification, ocean circulation, temperature, salinity, the wind field and sea ice cover. In turn, ocean ecosystems affect the chemical composition of the atmosphere (e.g. CO2, N2O, oxygen (O2), dimethyl sulphide (DMS) and sulphate aerosol). Most of these components are expected to change with a changing climate and high atmospheric CO2 conditions. Marine biota also influence the near-surface radiation budget through changes in the marine albedo and absorption of solar radiation (bio-optical heating). Feedbacks between marine ecosystems and climate change are complex because most involve the ocean’s physical responses and feedbacks to climate change. Increased surface temperatures and stratification should lead to increased photosynthetic fixation of CO2, but associated reductions in vertical mixing and overturning circulation may decrease the return of required nutrients to the surface ocean and alter the vertical export of carbon to the deeper ocean. The sign of the cumulative feedback to climate of all these processes is still unclear. Changes in the supply of micronutrients required for photosynthesis, in particular iron, through dust deposition to the ocean surface can modify marine biological production patterns. Ocean acidification due to uptake of anthropogenic CO2 may lead to shifts in ocean ecosystem structure and dynamics, which may alter the biological production and export from the surface ocean of organic carbon and calcium carbonate (CaCO3).

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-1-1.html

        I am not sure of a preference as much as familiarity. I read one of Gintis on Sen. It was a good read. From the link on Sen you had, it seems his nomenclature could be part of the problem such as having a dual use for utility. I will read others as time permits, but I expect like trying to understand something like “Free to Choose” it will require rereading and time. I hope to get to Nussbaum. The one I read had the feel of a hatchet job, the hatchet was used to make chopped liver of the work in order to give substance to a strawman was my take on it. Kibitzing has a good and honorable past, as does philosophy and scepticism.

      • John,

        Go ahead with Nussbaum. You won’t regret it. She writes clearly and beautifully, not like some commenters at Judy’s. And this will make you discover the Ancients, which is rarely a bad thing.

        Don’t worry, I meant kibitzing affectionately, like most chessplayers would. But they’re kibitzes, and even Grandmasters’ kibitzes are just that: kibitzes.

        I could have said Gremlins’ sounds, but I don’t know which verb should be used to express what Gremlins utter.

      • Latimer Alder

        @willard

        You are clearly using a different definition of ‘obvious’ than the rest of the world. If I need to read down to Chapter 7 of the IPCC report,, to look for some sentence that might be construed to be an expectation (not an observation) that there might be some small effects, then that is not ‘obvious’ by any rational criterion that I know. ‘Clear, self-evident or apparent’ it isn’t. ‘Obscure and speculative’ covers it well.

        You guys (yes, this time I am including the singular as well as the plural use of the word ‘you’) would be a lot more convincing if you didn’t consistently overstate your case. It’s too easy to find the holes when you do. And then we watch you just wriggling and squirming and giggling among yourselves. It seems that you have learnt nothing in the last five years.

      • Latimer Adler,

        Quite frankly, I could not care less about what you find obvious or not. I can’t say I’m that interested in Joshua’s claim either. It’s just some kibitin’.

        What interests me is to post snippets after snippets from a document on which, had you spent the tenth of the time you spent at Judy’s, you would be an international authority by now.

        You don’t seem to have read it. You might have. It’s just that nothing authorizes me to infer that you did, except your own personal testimony, which I find as authoritative as Stirling’s. (Yes, I used two Is: I prefer my Stirling stirred.)

        What matters to me is that I am quoting and citing the IPCC documents.

        For instance:

        > In many areas of the Earth, large amounts of SO4 particles are produced as a result of human activities (e.g., coal burning). With an elevated atmospheric aerosol load, principally in the Northern Hemisphere (NH), it is likely that the temperature increase during the last century has been smaller than the increase that would have resulted from radiative forcing by greenhouse gases alone. Other indirect effects of aerosols on climate include the evaporation of cloud particles through absorption of solar radiation by soot, which in this case provides a positive warming effect. Aerosols (i.e., dust) also deliver nitrogen (N), phosphorus and iron to the Earth’s surface; these nutrients could increase uptake of CO2 by marine and terrestrial ecosystems.

        This comes from section 7.1.3, entitled Atmospheric Chemistry and Climate

        Sooner or later, you will have to admit that all you have is your semantic quibble over “obvious”. Unless you would prefer to go watch the grass grow.

        That’s all you have left, I’m afraid. My pieces control all the board.

        You’re almost in zugzwang.

      • Latimer Alder

        @willard

        No. I am not Scottish like Groundskeeper Willy.

      • Latimer Alder

        @willard

        Somewhere along the way you have entirely lost your thread of this discussion. Which was about the ‘obviousness’ or otherwise of the remarks that Joshua made here

        http://judithcurry.com/2012/10/08/whats-the-best-climate-question-to-debate/#comment-250301

        If you feel that you have some how ‘won’ an argument with me about a different topic, then knock yourself out. I’m cool with it, You can sleep well tonight in that belief. But whatever it is you delude yourself that you have achieved, you have failed on the substantive point.

        Perhaps your Great Intellect meant that you spent so much time on the epistemological aspects, the informal logic and the fallacy theory that you actually forgot the main point?

        And your quote mining from the IPCC as if it is holy writ is reminding me more and more about the religious zealots I mentioned before,

        FWIW a quote from the IPCC that they expect something to happen or that something could happen is hardly conclusive proof of it, however much you might like to think it is.

      • Willard, As someone who played chess in tournaments and had a provisional rating until I had to give it up for studies, I appreciate kibitzing. Gremlin sounds would not register with me.

      • Latimer Adler,

        Here is the first sentence upon which I commented:

        > I’ll take your unwillingness/inability to present any evidence beyond ‘its obvious’ as an admission that you haven’t got any, shall I?.

        I believe that you’re not asking for “obvious” evidence, but for evidence beyond “it’s obvious”.

        I believe that the quotes I provided, especially the sentences underlined, point to some lines of evidence Joshua could invoke to meet your challenge. These lines of evidence are not to be obvious to meet your challenge: they only have to be evidence.

        It is you who changed the criterium on your next comment:

        > Any particular piece of the large and dull tome you would wish to draw to my attention vis a vis the topic under discussion – the ‘obviousness’ of bad effects of ACO2 other than climate change.

        I hope you do notice that asking for evidence about the bad effects of CO2 beyond “it’s obvious” is not the same as asking for obvious evidence.

        ***

        You know, Latimer, philosophy is a tough discipline. Philosophers have to learn to read, a skill that the climate debates convinced me is quite underestimated. Playing parsing games with philosophers needs careful preparation. You do not have the stuff yet to do so. If you want to see some examples, see:

        http://neverendingaudit.tumblr.com/tagged/parsomatic

        ***

        Notwithstanding all this, we can continue to quote chapter 7. Here’s an intriguing part on methane:

        > Atmospheric CH4 originates from both non-biogenic and biogenic sources. Non-biogenic CH4 includes emissions from fossil fuel mining and burning (natural gas, petroleum and coal), biomass burning, waste treatment and geological sources (fossil CH4 from natural gas seepage in sedimentary basins and geothermal/volcanic CH4). However, emissions from biogenic sources account for more than 70% of the global total. These sources include wetlands, rice agriculture, livestock, landfills, forests, oceans and termites. Emissions of CH4 from most of these sources involve ecosystem processes that result from complex sequences of events beginning with primary fermentation of organic macromolecules to acetic acid (CH3COOH), other carboxylic acids, alcohols, CO2 and hydrogen (H2), followed by secondary fermentation of the alcohols and carboxylic acids to acetate, H2 and CO2, which are finally converted to CH4 by the so-called methanogenic Archaea: CH3COOH → CH4 + CO2 and CO2 + 4H2 → CH4 + 2H2O (Conrad, 1996). Alternatively, CH4 sources can be divided into anthropogenic and natural. The anthropogenic sources include rice agriculture, livestock, landfills and waste treatment, some biomass burning, and fossil fuel combustion. Natural CH4 is emitted from sources such as wetlands, oceans, forests, fire, termites and geological sources.

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-4-1.html

        Thus it seems that methane output has something to do with CO2.

      • Latimer Alder

        @willard

        Despite all your havering, you have completely failed to establish the proposition. Realising that you find it hard to stick to the point, you will recall that I reminded you of it in a comment addressed directly to you here

        ‘http://judithcurry.com/2012/10/08/whats-the-best-climate-question-to-debate/#comment-250864

        ‘@willard4
        ………

        So – once again – where please are the ‘obvious’ parts of Joshua’s proposition?

        ‘That ACO2 has harmful impact irrespective of any potentially harmful influence on climate change is completely obvious’

        and all the clever-clever logic-chopping philosophy you can dream of won’t make it true. It is not obvious.

        The proposition falls.

      • Latimer Adler,

        I have not failed to establish that proposition, as I have not tried to establish it. You are now trying to burden me with a commitment I never take. In fact, you are backtracking to a point in the conversation I have not commented.

        In other words, brave, brave, brave Latimer is running away.

        Besides, nobody has any idea what you would find evidence. Nor have you set forth any criteria for what you would consider as evidence. Considering your utter lack of any kind of satisfaction in our auspices, nothing warrants that you’re not playing some kind of pea and thimble game right now.

        Take for instance the very concept of CO2. I don’t find the concept that obvious. There is at least one meaning of “obvious” that renders it trivially unobvious: it is completely invisible to the naked eye. The same reasoning applies to the concept of evidence.

        And all this while you have (say) ocean acidification right up under his nose. Go ahead, please tell us that ocean acidification is not evidence, or that it’s not obvious, or both, or “whatever”. As if I care, as if I was commited to that gruesome task of providing anything that you would find an obvious piece of evidence.

        ***

        Unless we have an idea of what would count as an obvious evidence, Latimer can always refuse to consider the evidence benevolently brought to him. And the he can always proclaim that he can’t get no satisfaction. No, no, no. Eh, eh, eh. That is what he says.

        Burdening a commenter with commitments he never took is a common trick. For instance, here’s a study where this has been done at Steve’s:

        > My sense was that my audience at Climate Audit had placed me on “one side” of what they saw as a “two sided debate,” and held me responsible for everything “my side” had ever said. That kind of refusal to allow a conversation partner to define the responsibilities she is willing to undertake is unlikely to lead to a productive discussion. In this particular case, I think the demands for to defend things we hadn’t said occluded possible areas of agreement about what we did say.

        http://scientistscitizens.wordpress.com/2011/07/26/debate-in-the-blogosphere-a-small-case-study/

        Of course, now that I’ve used the word “commitment”, Stirling and Joe will return and have a ball. The word commitment might not seem quite obvious to Latimer. At the very least, his last trick shows this quite clearly: he confuses my commitment (which was in reply to a specific sentence of his) and Joshua’s.

        ***

        Come what may, here’ are two quotes from chapter 7 of WG1, this time from 7.4.1.2, entitled Effects of Climate

        The first:

        > Changes in the hydrological cycle due to this CO2 doubling cause CH4 emissions from wetlands to increase by 78%.

        The second:

        > [A]ny change in climate that alters the amount and pattern of precipitation may significantly affect the CH4 oxidation capacity of soils. A process-based model simulation indicated that CH4 oxidation strongly depends on soil gas diffusivity, which is a function of soil bulk density and soil moisture content (Bogner et al., 2000; Del Grosso et al., 2000).

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-4-1-2.html

        And thus it seems that AGW leads to a modification of the chemistry of the soil and wetlands.

        That ought to raise no concern at all. Perhaps because it is not evidence. Or perhaps because it is not obvious. Who knows?

        Latimer, of course!

      • He said the sky is blue, but she said there’s white in it.
        =================

      • Willard:

        …he confuses my commitment (which was in reply to a specific sentence of his) and Joshua’s.

        Just as a point of clarification – I feel I have no “commitment” to Latimer. If he doesn’t think that harmful effects from burning fossil fuels – outside of impact on the climate – are obvious, so be it. I think such a viewpoint is absurd – and so it is obvious to me that there is no point in responding to his “challenge.” It’s clear that no matter what I would offer as evidence, he would claim it is invalid or isn’t obvious. He “challenge” is not in earnest. I’m content to simply state that anyone who is familiar with the evidence – as I have every reason to assume is true of Latimer – and thinks the effects of which I speak of aren’t obvious, is willing to believe in the absurd.

        I have encountered this type of situation with Latimer before – notably the first time over the use of the term “ocean acidification.” I won’t be chasing down any more of Latimer’s rabbit holes (h/t Keith). He’s entitled to think that I have a commitment that I haven’t fulfilled; It doesn’t bother me in the least.

      • Joshua,

        As I see it, you’re commited to your claims, not to Latimer’s judgement of what is obvious evidence to him. But you sure have the right to refuse to debate with Latimer, if only because he never seems to get no satisfaction.

        But please consider the other participants. You can’t tell them that your claim is obvious because, well, it is obvious. While Latimer’s request is not obviously made in good faith, it could be a good idea to still answer it by providing some lines of evidence.

        So, when you made this claim, what evidence did you have in mind?

      • Declining to answer, trying to say a question is not made in good faith as Willard wants to say, whatever that means …

        These are sure signs of intellectual bankruptcy. Best avoid them. Even the slippery Willard agrees.

      • Willard:

        But please consider the other participants. You can’t tell them that your claim is obvious because, well, it is obvious.

        If anyone, in good faith, asks for clarification, I’d be happy to do so. However, the evidence is abundant. Even a cursory investigation will turn up much. As simple an attempt as Googling “pollution from fossil fuels” will work for anyone interested. I’m not telling anyone it’s obvious because I say it’s obvious. I’m saying it’s obvious. If someone with an open mind doubts that, they will find that I’m correct. Given that the folks here are climate fanatics, I don’t see how anyone in these threads would have such questions in earnest.

        When Latimer invites me to enter his rabbit hole, I decline. If he wants to actually come out and make a point, he’s entitled to do so. If he thinks that air and water pollution from fossil fuels is not obvious, or don’t qualify as negative impact, he’s entitled.

      • Joshua has now clarified his position perfectly : he has no answer for Latimer, but is loathe to admit it.

      • Willard:

        Joshua has now clarified his position perfectly : he has no answer for Latimer, but is loathe to admit it.

        Do you not see my point? There is no reason to enter these rabbit holes. Let the rabbits amuse themselves. No one is harmed in the process.

      • Willard –

        A perfect illustration of what it’s like to enter those rabbit holes:

      • Tomcat,

        You claim that Joshua has no answer for Latimer.

        As far as I can tell, it seems that Joshua’s suggestion of making one’s own cursory investigation counts as an answer:

        > As simple an attempt as Googling “pollution from fossil fuels” will work for anyone interested.

        So I am not sure you have any ground for your claim.

        Would you care tell us how you reached that conclusion?

        ***

        That does not mean that it is an answer for Latimer, since he refuses to try play rabbit holes chases with him.

        That does not mean that it is an answer that could satisfy Latimer, for I have no reason to believe that it’s possible to “fire up” Latimer’s imagination enough to do so.

        Knowing what would count as a satisfying answer to Latimer is certainly an open problem I would like to solve. And I’m sure that Latimer tries to get satisfaction.

        And he tries.

        And he tries.

        And he tries.

        And he tries.

        But it doesn’t seem he can’t get no satisfaction.

        At the very least, that is what he constantly seems to say.

        If you know how Latimer can ever get some satisfaction, please tell us.

        Many thanks!

      • Joshua,

        Thank you for your reply and your video. Your commitment has been fulfilled satisfactorily enough.

        Now, please leave me to the chase. Your presence might distract the rabbits.

      • Joshua & Willard

        It’s really very simple. Either
        – you know what you’re talking about, and so can answer your questioner; or
        – you can’t answer, and make up all sorts of pathetic evasive excuses like the question lacks good faith, you don’t like rabbit holes, asking the person to go and find the evidence you claim, etc etc….. all of which indicate that you have no answer, but refuse to face up to that.

      • Tomcat,

        The claim that Latimer is underlining is this one:

        > Given that we all know, clearly, how ACO2 from a variety of sources has negative impact in addition to affecting the environment.

        I don’t think this is the same as the two-pronged claim you’re now underlining:

        > Either you can answer your questioner; or you can’t answer.

        which is trivially true, but only if we presume that the act of answering behaves like an on/off light switch with no dimmer.

        I believe that Joshua has just provided an answer: some keywords for a web search, keywords I admit finding quite obvious. Not that this means in any way that Latimer finds the expression “pollution from fossil fuels” obvious, mind you. As I said in an earlier request, a request you have yet to acknowledge, I have no idea what Latimer would find obvious.

        Would you like me to report what this web search gives me?

        ***

        Furthermore, I believe that Joshua’s answer contradicts this claim:

        > I’ll take your unwillingness/inability to present any evidence beyond ‘its obvious’ as an admission that you haven’t got any, shall I?

        Joshua has provided a justification for his refusal to go down Latimer’s hole. He also provided an answer. As far as I can tell, your alternative is been answered.

        If I can be frank with you, Tomcat, I believe that you’re using Joshua’s answer as a bait to switch the topic on Joshua’s person, which was not the topic of Joshua’s claim, nor Latimer’s.

        That does not look very slick, Tomcat.

        ***

        As promised to David Springer, who’s silence we can all hear after he tried to bully me yesterday, here’s a quote from section 7.1.5 of the WG1, entitled Coupling the Biogeochemical Cycles with the Climate System

        > It is well established that the level of atmospheric CO2, which directly influences the Earth’s temperature, depends critically on the rates of carbon uptake by the ocean and the land, which are also dependent on climate.

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-1-5.html

        Now, the emphasized expression is quite interesting. Would you say it is an expression that is similar to “it is obviously the case”?

        Many thanks!

      • Willard

        I hope you are finding amusement, intellectual nourishment even, in the rabbit hole. I might observe that a stoat would be more often seen in such a place, the creatures being partial to rabbits, but I don’t believe you to be ermine, and I fear the Stoat has, perhaps wisely, decided not to enagage in this particular warren chez Judy. But I digress.

        As promised to David Springer, who’s silence we can all hear after he tried to bully me yesterday

        A point of order. I have the unpleasant task of drawing your attention to an error in the above.

        It may or may not be obvious that Dave Springer engages in bullying. Some might even say that it is well established that he does, and could cite comments herein to provide evidence. However is not my point here to highlight the unpleasantness or otherwise of Dave’s interactions.

        Rather it is a more serious sin I have observed.

        As promised to David Springer, whose silence we can all hear after he tried to bully me yesterday

        The apostrophe is a cruel mistress.

        That is all.

        Carry on.

      • VeryTall,

        Thank you for your comment. I stand corrected. I will confide that I am quite ambivalent with all this.

        On the one hand, there is the feeling to do Philosophy the Old Skool way. This does not give me the impression to chase rabbits, but to play on the third or the fourth line of an hockey team:

        http://en.wikipedia.org/wiki/Line_(ice_hockey)

        When it’s technical, I feel like I’m on the checking line. When it’s not, I feel like I’m on the energy line. I’d rather remain on the third line and to follow the path of Bob Gainey:

        http://en.wikipedia.org/wiki/Bob_Gainey

        But there is a need to stand in front ofl punks like Latimer Adler or thugs like David Springer when they jump on the ice. And there are lots of players like that. We might even rename Judy’s Denizens the Syracuse Bulldogs (sorry BBD):

        http://en.wikipedia.org/wiki/Slap_Shot_(film)

        So one needs to learn to stand his ground. And so I have learned.

        On the other hand, this just feels empty. The Syracuse Bulldogs behave as if nothing ever happened. Where is the warrior way in a world void of honor?

        Thank you for the kind words,

        @willard, @joshua

        I’m flattered that while I was getting on with life in the real world (not ‘running away’, just busy elsewhere) untroubled by the KlimatAngst that seems to have so gripped you, you have found so much harmless amusement in analysing my question.

        And after all the to-ing and fro-ing and logic chopping and deep philosophical treatises it comes down to the conclusion that what is obvious to Joshua…is necessarily obvious to anyone else (me included). Very little evidence presented of such an effect and notably Joshua was not the one to provide it. It was left to Willard to spend three gos to eventually find an obscure sentence in an obscure part of the IPCC report to come up with something that even remotely supported the proposition. ‘Obvious’ it was not.

        Still, I guess ‘Care in the Community’ was always going to have teething problems :-(

        You ask ‘what would satisfy Latimer?’

        Simple.

        Observational evidence that all these bad things are happening. Not unfounded ‘predictions’ or ‘possibilities’ or ‘wouldve couldve shouldve mightve’ speculation from activists and especially not unproven models.

        If you come with real evidence, real data that can be shared and challenged and pored over from hundreds of different perspectives and confirmed by other researchers, then I’ll be satisfied. As to whether the theories built on that data are proven valid is another level of inquiry after that.

        We used to call this way of investigating things ‘science’.

        But it seems that you guys are more into philosophy, epistemiology and word game-playing than worrying about any such experimental/observational stuff.

      • Joshua & Willard

        Suggestion : if someone asks you a question, and you say the answer is obvious, and they then say don’t see this, *just tell them the answer*.

        If it really is obvious, they’ll probably kick themselves. If it it isn’t, you’ll both learn something. Win-win.

        Avoiding answering by bleating about rabbit holes etc just says you’re trying to hide your own militant ignorance.

      • Latimer Adler,

        First, you say:

        > I’m flattered that while I was getting on with life in the real world (not ‘running away’, just busy elsewhere

        My reference to Brave, Brave, Brave, Brave Latimer running away was meant to point at the fact that you have been backtracking to a point in the conversation with Joshua for which I had no commitment.

        You changed the question, accused me of having changed it, and burdened me with a question I had no commitment to fulfill.

        And now you’re just ignoring all this.

        ***

        Next you say that:

        > It comes down to the conclusion that what is obvious to Joshua…is necessarily obvious to anyone else (me included).

        I thought having forestalled this trick. Joshua already gave me an answer to this trick. What you find obvious or not does not appear to be any of his concern.

        Considering your distorsions, I can understand that.

        Next you say this about the evidence presented to you:

        > ‘Obvious’ it was not.

        As if this mattered in any way.

        ***

        Finally, you come up with this idea that deserves due diligence:

        > Observational evidence that all these bad things are happening.

        Not just evidence, but observational one. Of what? Something bad.

        Now, the observational evidence of something bad happening is an interesting concept. An obvious observational evidence of something bad happening is even more intriguing.

        I’m not sure I understand what you mean by that. I’m not sure I find that obvious. Perhaps you can give me an example. When was the last time you observed something what was obviously bad, Latimer?

        Could you observe the badness of that something?

        How was that badness came to be obvious to you?

        Just curious.

        ***

        Perhaps we can follow WG1 to see what’s inside. We still have more pages of chapter 7 to read. Then we could follow Moshpit’s advice and read WG2. What a spoil sport: there was no hurry.

        Here’s from 7.5.1.2, **Sea Salt**

        There is evidence of physiological adaptation to higher temperatures that would lead to a greater response for long-term temperature changes (Guenther et al., 1999). The response of biogenic secondary organic carbon aerosol production to a temperature change, however, could be considerably lower than the response of biogenic VOC emissions since aerosol yields can decrease with increasing temperature. A potentially important feedback among forest ecosystems, greenhouse gases, aerosols and climate exists through increased photosynthesis and forest growth due to increasing temperatures and CO2 fertilization (Kulmala et al., 2004). Increased forest biomass would increase VOC emissions and thereby organic aerosol production. This couples the climate effect of CO2 with that of aerosols.

        New evidence shows that the ocean also acts as a source of organic matter from biogenic origin […] Surface-active organic matter of biogenic origin […] enriched in the oceanic surface layer and transferred to the atmosphere by bubble-bursting processes, are the most likely candidates to contribute to the observed organic fraction in marine aerosol. Insoluble heat-resistant organic sub-micrometre particles (peaking at 40 to 50 nm in diameter), mostly combined into chains or aggregated balls of ‘marine microcolloids’ linked by an amorphous electron-transparent material with properties entirely consistent with exopolymer secretions (Decho, 1990; Verdugo et al., 2004), are found in near-surface water of lower-latitude oceans (Benner et al., 1992; Wells and Goldberg, 1994), in leads between ice floes (Bigg et al., 2004), above the arctic pack ice (Leck and Bigg, 2005a) and over lower-latitude oceans (Leck and Bigg, 2005b). This aerosol formation pathway may constitute an ice (microorganisms)-ocean-aerosol-cloud feedback.

        http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch7s7-5-1-2.html

        Interestingly, we can find the word “evidence”, but not the word “obvious”, nor the word “bad”.

        You should really wonder why, Latimer. .

        I just wanted you to know that I am not ‘running away’ from it.

        I read it, tried to extract some substantive meaning from it, failed and gave up.

        So the reason you will not see a further reply is that I see no point on wasting my time on it. You can indulge your word games by yourself or with your little playmates

        But please leave the adults to get on with debating the ‘climate issue’ in peace.

      • Joshua,

        I believe that next time Latimer Adler shows up again to bug you with is ignorant pest act, you can always reply to him:

        > [T]he reason you will not see a further reply is that I see no point on wasting my time on it. You can indulge your word games by yourself or with your little playmates.

        Oh. Wait. Perhaps you already did!

        ***

        Now, what did Latimer inferred from such a refusal to respond?

      • Latimer Alder

        @Willard

        If I were ever to write such a content-free bunch of incomprehensible drivel as your post to which my remark specifically referred, then Joshua (or anybody else) would be fully entitled to make such a reply.

        But I try hard to avoid being unclear or unspecific. So I hope that that particular charge cannot often be laid at my door.

        Simple advice to any alarmist….while you may be able to get away with sweeping generalisations in your private discussions or in highly regulated cheerleader blogs, be prepared to justify them in public fora.

        And to Willard specifically….you do not gain extra brownie points for the esoteric and obscure nature of your posts. If you can’t say what you mean clearly and directly, then keep your powder dry.

  34. Folks, WE can debate these issues here, but it makes no sense whatsoever for US Presidential candidates to engage in a debate surrounding climate science or policy for a few reasons:

    – Neither candidate knows enough about the science to have come to any valid conclusions.

    – The science is NOT settled

    – There is nothing that a US President can do to change our planet’s climate

    – The issue itself is of such minor importance to US voters, that there is no use wasting time to debate it

    We are being presumptive to assume that this issue (which may be of great interest to us personally) is of any real interest to the US voters, in general, or the US presidential candidates.

    Better yet would be to debate an energy policy for the USA, including opening up exploratory oil and gas drilling including shale deposits, limiting the exponential growth of regulations currently stifling new exploration, ending the EPA regulatory war on coal, reactivating the Keystone pipeline, etc.; these issues have direct impact on American jobs and future energy independence, both of which are more important issues for US voters (and presidential candidates) than any “climate” debate.

    • I point to Manacker’s appeal to US politics, and I point to Judy’s last paragraph:

      > This is a very good question to ponder, its at the heart of the climate policy debate. How would you answer this question? For the moment, accept that there is ‘some’ warming that is attributable to CO2 (i.e. lets not debate the fundamental science here, but uncertainty assessments are ok). Please keep your responses on topic.

      That is all.

      • Apparently coming up with thoughts of your own is a bit challenging, huh willard?

      • timg56,

        You seem to presume that Manacker’s comments contain original thoughts. That presumption lacks evidence, to say the last. As far as I am concerned, Manacker rinses and repeats the same claptraps day in, day out, disregarding most of the discussions he had with the commenters, including me.

        Since you ask so gently, I could tell you that I think the most important policy should recreate the magic of washing machines:

        > And what’s the magic with them? My mother explained the magic with this machine the very, very first day. She said, “Now Hans, we have loaded the laundry. The machine will make the work. And now we can go to the library.” Because this is the magic: you load the laundry, and what do you get out of the machine? You get books out of the machines, children’s books. And mother got time to read for me. She loved this. I got the “ABC’s” — this is where I started my career as a professor, when my mother had time to read for me. And she also got books for herself. She managed to study English and learn that as a foreign language. And she read so many novels, so many different novels here. And we really, we really loved this machine.

        http://www.youtube.com/watch?v=Bw6NxCcvipQ

        Considering the quality of the debate at Judy’s, I must admit that washing machines might not be enough.

        But that would be a good start.

      • A majority of people here, including myself, tend to repeat comments and opinions. I was commenting on you repeatedly responding with a quote from Dr Curry above. A tactic in response to other posters? Ok.

        As for the washing machine story – whatever. I recall the first washing machine my mon’s mom had. It was electric, open topped, with an agitator. You had to squeeze the water and suds out by hand, drain the machine and refill with water, then repeat the process. Both our stories have the same bearing on climate discussions.

      • > As for the washing machine story – whatever.

        Thank you for your comment.

    • Max
      I tend to disagree with your stated conclusion(s).

      You concluded: Neither candidate knows enough about the science to have come to any valid conclusions.

      I do not know this to be true and do not think you have any special knowledge about the relative knowledge of each of the candidates. Romney appears to know enough to believe that restricting CO2 emissions in the US may create more national harms than benefits. Obama seems to desire that CO2 emissions be limited, but it would be enlightening if he would be able to justify the reasoning behind the position for voters.

      You concluded: There is nothing that a US President can do to change our planet’s climate.
      I respectfully disagree. Policies supported by a US president could have a long term impact, but I agree that the climate impact will not be very large.

      You concluded: The issue itself is of such minor importance to US voters, that there is no use wasting time to debate it.

      I again respectfully disagree. Because the issue of CO2 emissions is tied closely to domestic energy production in the US over the next 20 to 30 years, there is a potential large impact in the USA on the domestic economy. If Romney was elected and if his policies were enacted, there could be a substantial increase in the development of US fossil fuels and a substantial intermediate positive impact on domestic employment and the availability of domestic capital. US voters would be more likely to support the development of these resources if they were better informed of the facts on the impacts on employment and capital availability and of the lack of clear scientific conclusions regarding the negative consequences to the USA.

      • > Romney appears to know enough to believe that restricting CO2 emissions in the US may create more national harms than benefits.

        WebHubTelescope has a nice serie on Romney’s view on energy issues. For instance:

        http://judithcurry.com/2012/09/07/climate-change-and-u-s-presidential-politics/#comment-236990

        The whole serie would make an interesting G Doc.

        Wink wink.

      • Some have pointed out that this book was likely ghost-written for Mitt Romney. There is a distinct possibility that Romney probably doesn’t even realize that he has labelled himself a peak oiler.

      • WebHubTelescope,

        Unless we could prove that Willard Romney has ideas of his own, I don’t see the problem with ghost writers. I might be biased.

      • WHT

        Who’s “ghost writing” your posts for you?

        [Whoever it is, you should fire the guy.]

        Max

      • Willard and Webby

        The quote from Mitt Romney’s (allegedly “ghostwritten”) book points to the conclusion that the USA should do more oil and gas exploration (“drill, baby, drill”) including shale deposits, to get more “energy independent” (combined, of course, with supporting basic research for new energy technologies).

        All makes sense to me – and it appears that this is the course Mitt Romney will take if he becomes the new US President.

        Max

      • Manacker,

        You jest while you have homework to do:

        Many thanks!

      • Rob Starkey

        Whether Mitt Romney “knows more” about climate science than Barack Obama is possible but uncertain – that neither is an expert is fairly certain. (Both have had other things to worry about.)

        I agree with you that Romney probably has a slightly better understanding of industry than Obama, based on their backgrounds.

        But I believe that, apart from “giving a signal to the world”, there is not much either could do to change our planet’s future climate.

        Let’s say the new US President takes the bull by the horns and cuts 50% of the US CO2 emissions starting the day after he takes office (maybe not completely impossible but highly improbable).

        Wiki tells us that USA emits 5.5 GtCO2/year (2010) out of a global total of 33.5 GtCO2 (China emits 8.2 GtCO2).

        Without this drastic USA cutback, IPCC estimates that we will reach 600 ppmv CO2 by 2100 (average of cases B1 and A1T, both assuming no special “climate initiatives”, population growth rate slowing down reaching 10.5 billion by 2100, with medium and fast economic growth rate).

        The cutback will result in a cumulated CO2 reduction of 96.8 GtCO2, of which 50% will “remain” in the atmosphere.

        This will result in a calculated reduction of atmospheric CO2 of 6.2 ppmv.

        Using the logarithmic relation and IPCC’s model-derived 2xCO2 climate sensitivity of 3°C, we have a net reduction in global warming by 2100 of 0.045°C.

        If the new US President shuts down the present CO2 emissions completely today, we would have a net reduction in global warming of 0.09°C by 2100.

        Neither reduction could be measurable.

        IOW, there is not much the new US President can do to change our planet’s climate.

        And that was my point.

        Max

      • PS That “dratstically cutting back CO2” versus “drill, baby, drill” would have severe economic consequences for the USA is another matter.

        It would, at least one candidate knows this, and (if he’s elected) it won’t happen.

        It is unlikely that the incumbent (if re-elected) will enjoy having Congress on his side, so any attempt to force a CO2 reduction through the EPA will get strong opposition. But it will still be a totally unproductive nuisance and the negative job impact of not doing “drill, baby, drill” will be significant.

        My opinion, as an outsider

  35. Hi Judy –

    I feel Andy has too narrowly posed the question. What should be asked is

    What are the major threats to local and regional water, food, energy, human health, and ecosystem function resources from extreme events including climate, of which added CO2 and other greenhouse gases are a part, but also from other social and environmental issues? After these threats are identified for each resource, then the relative risks can be compared with other risks in order to adopt optimal preferred mitigation/adaptation strategies.

    To focus on “greenhouse-driven global warming” is much too narrow, as we reported on in

        In that comment thread, I found back this old thread at Judy’s:

        http://judithcurry.com/2011/12/01/the-long-slow-thaw/

        ***

        This is the 20000 feet overview. Today’s debate centers around this comment by Tom Curtis:

        Steve, I have already answered precisely this question from you from another thread […] As you responded to that comment, you are certainly aware of my opinion; so your raising the question again must be regarded as a deliberate red herring.

        Speaking of which, the issue raised by you in the OP was whether the IPCC 1990 graphic was used by climate scientists in the period 1992-1995 in a way that would rebut John Mashey’s claim that by 1992 it had been rejected as misrepresenting what really occurred. You suggest two putative counter-examples, and as I have clearly demonstrated, they are not actually counter-examples. Both were ammended significantly in ways that reduced the presumed MWP warmth, and the later (the only actually relevant one, as being post 1991) clearly only treats it as a regional proxy, not a global proxy (however qualified). As such you have no counter-example.

        I have noted since then that you and your friends have been piling on with points to debate, none of which are relevant to the main point. I am not here to debate all of climate science. Therefore I have no interest in being distracted by your various red herrings. Either defend your initial claim that IPCC 1990 Fig 7.1(c) was still considered an adequate estimate of global MWP warmth in the mid 1990s, or admit your error. Continued red herrings will only show me that you neither have the means to do the former, nor the integrity to do the later.

      • willard,

        after seeing many of the subsequant comments by you I take back the Dumb and Dumber crack. It was a response to the early repeated referals back to Judith’s comments. My apologies.

  36. Dr Curry. I must ask: Are you going for a CE blog recording number of comments to a posting? This may be the one!

  37. Any question based on the premise that “the long-term picture of a profoundly changed Earth is clear” is not a good question, rather it is a question that ignores the debate. The line about minimizing regrets then nullifies this premise, regrets for what we ask, that the premise is false? How can it be both clear and possibly false? Thus the question is internally inconsistent, hence meaningless. Revkin at his best. He does this all the time.

    • Any question based on the premise that “the long-term picture of a profoundly changed Earth is clear” is not a good question,

      Strictly as a matter of logic, that is an entirely subjective determination. It may not be a “good question” from your perspective, but your perspective is not the only perspective.

      rather it is a question that ignores the debate.

      Again, subjective. There is no “the” debate. It makes a presumption about the debate that you want to have (that it is out of touch with reality), but it focuses on a debate that others are interested in.

      If you object that Revkin’s assumptions are not sufficiently inclusive, then perhaps you shouldn’t make similarly exclusive assumptions.

      How can it be both clear and possibly false?

      Again, you are assuming that your perspective is the only valid perspective. “It” is not possibly false from Revkin’s point of view.

      Thus the question is internally inconsistent, hence meaningless.

      No. It is inconsistent from your (external) perspective – not from the logic internal to his perspective.

      Revkin at his best. He does this all the time.

      Hmmmm.

      • David Wojick

        All we have are our beliefs Joshua, so your points are pointless.

      • My point wasn’t that everyone has beliefs, David.

        My point is that when people confuse belief with fact – as you did in your comment – we run into problems. That would apply to discussants no matter on which side of the debate they reside.

        You are certainly entitled to believe otherwise, but my belief is that confusion between fact and opinion renders the climate debate to be of relatively little value other than possibly as an object lesson (as are other proxy debates) in how motivated reasoning affects discourse and reasoning in controversial issues that overlap with political, social, cultural, and personal identifications.

        I will note, however, that you consider speaking to your confusion between fact and opinion as “pointless.”

      • David Wojick

        No Joshua, I did not say you said all we have are beliefs, your mistake is not knowing this. There is no confusion between facts and beliefs. All humans have are beliefs. If they correspond with the facts they are true, if not they are false. Facts and beliefs are fundamentally different things. By the same token, everything everyone believes is subjective, but that is no argument against it, and it is pointless to point it out as some sort of criticism. This is basic epistemology.

      • David –

        There is no confusion between facts and beliefs.

        Except that there is widespread confusion in that regard, and more specifically, it was apparent in your first post I responded to, You confused fact and belief. You stated your (subjective) belief as a fact (apparently, and ironically, in objection to what you felt was Revkin stating opinions as fact).

        By the same token, everything everyone believes is subjective, but that is no argument against it, and it is pointless to point it out as some sort of criticism.

        “It” has an ambiguous antecedent there – but I suspect you are mistaken. I am not criticizing subjectivity. Of course opinions are subjective. And opinions are perfectly valid.

        I am criticizing an failure to acknowledge subjectivity.

        I think my point has been rather clear. You have repeatedly misconstrued my point – It seems in a defensive way. I’ll leave it there.

  38. What’s the best climate question to debate?

    What percentage of the warming we have experienced since 1850 is due to the increase in CO2?

    • The prior question is how much warming have we experienced? This is far from clear.

      • This is far from clear.

        I thought that you have said that you are quite sure that there is no valid evidence that Earth has warmed. For that I gave you credit among “skeptics” for being internally consistent. Am I wrong or have you changed your mind?

      • I have said repeatedly that there is a step function warming in the satellite record, coincident with the big ENSO cycle. This is real warming but it looks natural. Other than that the satellite record says that the warming shown in the surface statistical models does not exist. It follows that we do not know that the post 1850 warming shown in the surface models actually exists.

      • How does one event (a big ENSO cycle) warm the Earth over time? Doesn’t it stand to reason that a “cycle” implies cyclical change, not a state change as in “the Earth has warmed?”

      • I will point at Judy’s:

        > For the moment, accept that there is ‘some’ warming that is attributable to CO2 (i.e. lets not debate the fundamental science here, but uncertainty assessments are ok).

        That is all.

      • The atmosphere is incapable of being permanently stepped up in temperature by a big ENSO. You are deceiving yourself. There is no way for it to retain it. It mostly all goes away in months. The sunlight comes every day. Every day the energy interacts with the atmosphere, which determines how much stays and how much goes. Because there is a growing enhanced GHE, GMT and OHC have gone up. As was predicted decades ago.

      • Joshua, “How does one event (a big ENSO cycle) warm the Earth over time? Doesn’t it stand to reason that a “cycle” implies cyclical change, not a state change as in “the Earth has warmed?””

        Over what time? 1976 to 1998 is 22 years, that is about 1/3 of an AMO cycle and 2/3 of a PDO cycle. There are also cyclic Bond events with ~1500 year periods that have 6 to 10 decay oscillations. That would be ~150 to 250 year pseudo cycles created by a roughly 1500 year recurrence. Those Bond Events appear to be recurrent pseudo cycles of a 4300 to 5500 year decay recurrences for a 23K year orbital cycle of perturbations. 22 years is about 0.1% of a long-term picture.

      • Cap’n –

        Near as I can tell, you’re speaking hypothetically whereas David is pointing to a specific ENSO cycle. Thus my question to him – how did “the big ENSO” in question lead to a state change?

        W/r/t your comment, should I assume that your comment means that you do not think that the “Earth has warmed?”

        Or do you think it has warmed to some extent, and to some extent of the extent due to ACO2? If that is the case, then how do you make that determination – as it would require that you distinguish that warming from the long-term cyclical patterns you describe?

      • Joshua, “W/r/t your comment, should I assume that your comment means that you do not think that the “Earth has warmed?” That would be evidence of your confirmation bias :)

        The Earth has warmed since 1976 after taking a break from warming in 1945 from warming that started in 1900. There has been a rather steady warming trend of 0.4 per decade in the tropics, 0.6 c per decade in the southern extra tropics and 0.8C per decade in the northern extratropics since 1900. CO2 may have added 30% to 50% to the warming since 1900. The 1998 Super El Nino was likely the bookend for the 1946 Super Duper La Nina :)

        http://redneckphysics.blogspot.com/2012/09/super-duper-la-nina.html

        Non-linear systems have non-linear occurrences, hence the name. Just like waves on the ocean, you can follow the oscillations back to the cause.

      • David Wojick

        Joshua, I am not claiming that the big ENSO caused the step warming, just pointing out the pattern. It seems likely the two are connected, possibly via an ocean circulation change along the lines of the standard theory of abrupt events, but that is merely a conjecture.

      • David,
        There’s probably a connection. That connection is that ENSO caused an illusion of step change while nothing like that really happened.

        When you have a gradual warming trend and add to that an exceptionally strong ENSO you get this illusion. That’s all.

      • David Wojick

        Pekka, the fact that there was no significant warming for the 20 years preceding the big ENSO is hardly an illusion. It was widely discussed at the time. Nor is the fact that there has been no warming since the ENSO (but the average temperature is a little higher than before). The pattern is too simple to be an illusion, not to mention that the term illusion has no place in data analysis. Try using mathematical language if you have an actual point to make.

      • JCH
        I have provided a fair answer for you on RC but Gavin removed it. The difference between RC and Climate etc and WUWT is more than obvous
        you can find it here:

      • ..that there was no significant warming for the 20 years preceding the big ENSO is hardly an illusion.

        But it’s not true either. The warming from 1978 to 1998 was very clear, actually exceptionally strong in comparison with any other period.

        That one satellite data set is inconclusive is irrelevant for the full picture. The interpretation that you have is not at all supportable by the data. It’s just your imagination. You have used the big ENSO as help for misleading cherry picking to create something from nothing.

        ______
        Precisely. The oceans act as a buffer and storage of energy, releasing more or less to the atmosphere, depending on ENSO cycles, but resulting in a zero-sum long-term net gain to Earth’s energy system (i.e. ENSO does not create any new energy in Earth’s overall energy system). The Longer-term rate of ocean heat storage is modulated by the total amount of greenhouse gases in the atmosphere which ultimately alter the net overall thermal gradient between ocean heat and space.

      • R GATES : The Longer-term rate of ocean heat storage is modulated by the total amount of greenhouse gases in the atmosphere which ultimately alter the net overall thermal gradient between ocean heat and space.

        So if the thermal gradient is being reduced by the greenhouse gasses which raise the air temperature, the oceans should warm ?

      • Bated,
        A warming lower troposphere results from increased greenhouse gases in the troposphere, with differing effects on other regions of the overall atmosphere (cooling in the stratosphere and mesosphere for example). But it must always be remembered that net energy flow is always from ocean to atmosphere, thus, it is not the higher temperatures of the lower troposphere themselves that are somehow (against the laws of thermodynamics) imparting energy to the oceans, for the lower troposphere is almost always cooler than the ocean on average. Rather, the warming lower troposphere acts a governor or control valve, reducing the rate of net heat flux between ocean and atmosphere. This is a fortuitous thing, for if there was not this alteration of the energy flow, with the oceans absorbing more heat being the excellent heat sink they are, we’d have a much faster warming troposphere as greenhouse gases increase.
        Despite a modest level of uncertainty, we can see that the oceans have gained roughly about 25 x 10^22 Joules of energy down to about 2000m over the past 50 years. Arriving at this number involves looking at both hard data and extrapolations to consistent paleodata. The gain in ocean heat content has been remarkably consistent over this period, closely paralleling the rise in global greenhouse gases (we must not forget the rapid rise in both Methane and N2O as well).

        Finally, the fact that both the oceans and the atmosphere are at their all time highest temperatures over the past 10 year average from instrument record and through extrapolation to near-term paleodata, we can see a remarkable consistent effect of what increasing greenhouse gases do to overall alterations in Earth’s non-tectonic energy storage.

      • RGATES

        Your answer to my question
        “So if the thermal gradient is being reduced by the greenhouse gasses which raise the air temperature, the oceans should warm ?”
        seems to be
        “the warming lower troposphere acts a governor or control valve, reducing the rate of net heat flux between ocean and atmosphere”

        IOW, “Yes”. The result of a warming lower troposphere is a warming ocean. Is that your position ?

      • Bated,
        Yes, the net result of a warmer troposphere OVER THE LONG RUN is that more heat stays in the ocean, as the thermal gradient between ocean and space is altered. But you need to be very clear NOT to infer that it is the troposphere warming the ocean, as net heat always flows from ocean to atmosphere. A warmer atmosphere simply slows down the rate of heat flux from ocean to atmosphere. In very simple terms, it is not any different than you putting on a jacket on a cold winter day. No net energy is flowing from the jacket to your body, but your body stays warmer because the heat flow is reduced because the thermal gradient from body to the space outside the jacket is made less steep by the jacket. The only difference in this analogy and the way the ocean-atmosphere heat flux works is that your body is warmed through metabolism, with the source of that energy being the food you eat. The oceans are of course warmed primarily by the sun.

      • RGATES
        Yes your idea is mostly clear : Basically the oceans warm as a result of the atmosphere warming. Not because heat from the atmosphere warns the ocean, but because heat flow from ocean to atmosphere – which is the norm – is slowed down.

        The part that isn’t clear at all, is that you stress this is in the longer term only. Why only longer term?

      • The Skeptical Warmist (aka R. Gates)

        Bated,

        Over short periods of time natural variability such as from ENSO for example, can create short term effects that run contrary to the longer term trend of increasing ocean heat content and higher tropospheric temperatures. For example, at the end of a very intense El Niño, we might see ocean heat content dip a bit while tropospheric temperatures spike. The reason is simple– a huge amount of energy, well above the long term norm, is leaving the ocean and moving into the troposphere. Related to this is the fact that many people get confused about sea surface temperatures and ocean heat content, and understanding their fundamental difference, how they are measured, and what they are measuring is important. SST’s are often, but not always, better gauges for how much heat is leaving the ocean on the way to the atmosphere rather than how much remains at depth to be measured as ocean heat content. Thus, the higher SST’s during an El Niño are an excellent predictor for seeing higher tropospheric temperatures a few months later as those higher SSTs are energy on the way out of the ocean.

      • R GATES
        Yes, I can appreciate that sometimes the oceans may not be warming in line with the general longer trend.
        But in times when they ARE warming, your idea is that this is down to a warmer atmosphere slowing down the rate at which the oceans cool into the atmosphere ?

      • The Skeptical Warmist (aka R. Gates)

        Bated,

        There are only 2 things that can increase the longer-term ocean warming– more solar reaching them and/or less energy leaving them. Solar cycles, aerosols, cloud cover and greenhouse gas concentrations each play a roll, and in general, increasing CO2, methane, and N2O in the troposphere will serve to reduce the net flow of energy from oceans to space.

      • R GATES
        Yes that much was already clear from your earlier comments thanks. But you haven’t addressed my specific question from before though :

        In times when oceans ARE warming, your idea is that this is down to a warmer atmosphere slowing down the rate at which the oceans cool into the atmosphere ?

      • The Skeptical Warmist (aka R. Gates)

        Bated asks:

        “In times when oceans ARE warming, your idea is that this is down to a warmer atmosphere slowing down the rate at which the oceans cool into the atmosphere ?”

        ____
        Sorry, thought my answer was quite clear, but to be specific:

        In times when the oceans are warming, there could be several factors that influence this, each with varying contributions based on natural and/or anthropogenic variability:
        1) Greater solar output
        2) Less aerosols in the atmosphere
        3) Less cloudiness (especially of a certain type)
        4) Increased greenhouse gases

        So, for example, if we go through a period of relative higher solar output, and less volcanic activity, relatively less cloudiness, and higher greenhouse gas levels, these would all tend to increase ocean heat content. It takes actual research (much of which is ongoing related to these specific issues) to find out the relative contributions of each of these during any specific period.

        Is this clear enough?

      • RGATES
        Yes thanks, That much was already clear from your earlier comments though, and doesn’t relate to my question – which has I fear has itself become unclear due to my attempts to rephrase it… Anyway, so we understand that there can be factors other than greenhouses gasses warming the earth, but that’s not what I’m asking about.

        What I am asking about, is your point about the greenhouse effect warming the oceans, indirectly, by warming the atmosphere, thereby reducing the ocean-atmosphere temperature gradient, thereby slowing the rate the oceans cool into the atmosphere, resulting in warmer oceans

        The point here is, that the prerequisite and tell-tale sign of this particular ocean-warming process, is warming of the atmosphere. Agreed ?

      • The Skeptical Warmist (aka R. Gates)

        Bated,

        Filtering out all other factors and natural variability, yes, for the thermal gradient between ocean and space to change and the heat flux from ocean to atmosphere to be reduced, the atmosphere would have to warm over the diurnal period. That is, you would not have to see record daytime temperatures, but you would have to then see higher night time tempertures, such that the average diurnal temperature across the whole planet, at all latitudes would have to increase.

      • RGATES

        Yes, that is what I was trying to work out – that for ocean warming to be a consequence of atmospheric warming – albeit an indirect consequence as you aver – you would still need to see atmospheric warming. (Sounds kind of obvious, now that I put is that way).

        The problem I see though, is that for over a decade we have not really had atmospheric warming, and yet the oceans have been warming. Which suggests some factor other than atmospheric warming is behind ocean warming.

      • Chief Hydrologist

        Yah think?

      • David Wojick October 8, 2012 at 12:40 pm: “I have said repeatedly that there is a step function warming in the satellite record, coincident with the big ENSO cycle. This is real warming but it looks natural. Other than that the satellite record says that the warming shown in the surface statistical models does not exist….”
        I totally agree. That is exactly what I said in my book “What Warming?” whose second edition has been out since 2010. Apparently the majority of climate scientists are too busy imagining what global warming will do to us to read that non peer-reviewed, non otherwise-reviewed, book that tells them what real climate is actually doing. The satellite model you refer to in fact tells us that actual global temperature from 1979 to 1997 showed only ENSO oscillations while global mean temperature at the same time stayed constant. The step warming itself was caused by the large amount of warm water carried across the ocean by the super El Nino of 1998. In four years it raised global temperature by a third of a degree Celsius and then stopped. This step warming and not any imaginary greenhouse effect was responsible for the record warm first decade of our century. It was also the only warming recorded in the satellite era which began with the year 1979. Various ecological changes – population movements for example – are due to this step warming and not to an imaginary “late twentieth century warming” found on many establishment temperature curves. That fake warming is found in the time slot of the eighties and nineties. It neatly blots out the absence of warming and hides the existence of the step warming. These manipulated temperature curves include Hansen’s Land-Ocean of GISS as well as Müller’s of BEST, but strangely enough not GISTEMP itself.

    • Yes, how much warming is the prior question – the 2010s may not be that much warmer than the ~1940s as the consensus global temperature indices show (~0.5 °C?). It could be less or practically zero, but even if it is, it’s not necessarily a gain in internal energy of the system.

      However, this is all somewhat irrelevant, since we’re trying to falsify the consensus (A)CO2(GHG)GW hypothesis. So, we don’t have to guess how much warming and how it is attributed. All the accepted global temperature indices and attributions are very similar so we can say that there is an official position and explanation. It can be represented by this for example:

      http://climate.uu-uno.org/files/103401_103500/103413/temp-vs-models-spm4.jpg

      Only further warming can save the warmists and I don’t see it coming, au contraire. Buy aerosols.

      • Yes, I agree that the consensus science doesn’t have a very good idea of how much warming is due to increased CO2, versus all the other potential causes versus natural variability. IMO, it’s all natural (non-anthropogenic), but I may be wrong. Some local warming (the so-called UHI etc) is for sure real and anthropogenic.

        However, there is an officially alleged AGW and it’s to falsified. It started in ~1960 and it’s about 0.7 °C. It’s more than 100% anthropogenic. It looks like this:

        _____

        Looking at the larger (and more consistent high thermal inertia) energy storage of the Earth system- the oceans- shows much more energy in the overall system than the 1940’s. The atmosphere has far less thermal inertia and is far more subject to short-term natural noise in the system.

    • It really matters to making policy how much of the warming is from CO2, and how much is from methane, land use changes, urban island (asphalt, concrete, air conditioning, etc.), carbon black, solar changes (sun activity lower and heliosphere at low level), or the catch all – natural variability.

      If CO2 caused 50% of the .8C in warming, that has a very different policy implication than if CO2 caused 80% or 20%.

      Spending trillions to solve a fraction of a 20% problem may not make sense.

      Maybe it would to solve a fraction of a 80% problem?

      Before we can act, we have to define the problem, and good solid estimates of how much warming is caused by the increased CO2 since 1850 seems to be the very first step in defining the problem, and am important step in doing a cost benefit analysis.

      I don’t think we have a very good idea of how much warming is due to increased CO2, versus all the other potential causes versus natural variability.

      • RickA | October 8, 2012 at 1:24 pm |: “If CO2 caused 50% of the .8C in warming, that has a very different policy implication than if CO2 caused 80% or 20%.”
        Quite true. And if it caused 0% of that .8C warming it would be another game entirely. I say that because there are several reasons for thinking that 0 is the correct percentage. First, take a look at global temperature. There has been no warming at all since the beginning of our century. But IPCC AR4 predicted in 2007 that greenhouse warming of the twenty-first century shall proceed at the rate of 0.2 degrees Celsius per decade. We are now in the second decade of this century and there is no sign whatsoever of this predicted warming. In science, if a theory makes a prediction that is false the theory itself is considered false and must be abandoned. The greenhouse theory used by the IPCC to predict warming has made a false prediction and therefore it must be abandoned. But that is not the only reason to doubt it. Ferenc Miskolczi used the weather balloon database going back to 1948 and discovered that the infrared transmittance of the atmosphere had been constant for 61 years. At the same time the amount of carbon dioxide in the air increased by 21.6 percent. This means that addition of all this carbon dioxide to the atmosphere had no effect at all on the absorption of IR by the atmosphere. And no absorption means no greenhouse effect, case closed. Specifically, this means that the enhanced greenhouse effect, the one we are told is warming up the world, simply does not exist. And with it all predictions of warming based on the greenhouse effect are proven to be completely wrong.

  39. Judy,

    That is certainly a good question, but I sincerely believe that the second best question is this one:

    > All of a sudden, these normally gentle creatures are becoming agitated and making noises with their mouths! What is it, guys? Is Timmy stuck in a well?

    http://www.theonion.com/video/nations-climatologists-exhibiting-strange-behavior,21009/

  40. Don’t have time to provide proper support, but I can summarize in one word: REMEDIATION!

    That is, let fossil energy development continue without restraint, while concentrating on technology to independently remove CO2 from the atmosphere/ocean, or perhaps bicarbonate from the ocean.

    Several reasons:

    – We can’t be certain that atmospheric CO2 is really going to cause any substantial harm, but we can be reasonably sure that anything that raises the price of energy (e.g. mitigation, that is reducing emissions at the source) will impact improvements in lifestyle that most of the world wants. It will thus probably be politically infeasible.

    – New technology of this sort tends to follow an exponential growth curve, so that if properly managed it could become mature within a few decades, being then able to balance existing emissions and start a drawdown process that could quickly make up for the previous century’s emissions. This means CO2 could be returned to pre-industrial levels without impacting the continuous improvement in lifestyle most of the world wants.

    – We can’t be sure that dumping of fossil carbon into the atmosphere is the primary reason for increasing pCO2. Sure, the smart money will bet that way (I sure would), but there are a variety of human interferences with natural ecosystems that could plausibly be more important contributors. These include whaling and overfishing, swamp/wetland drainage, expansion of irrigated mechanized agriculture, deforestation, and a host of others I’m too busy to think through and list.

    – We can’t be sure, now that the CO2 is in the atmosphere/ocean, that stopping mitigation will cause natural processes to remove it. Active removal (remediation) will remove it regardless of the source or other processes. It could directly balance emissions, as well as drawing down natural sinks/sources that contribute to the high pCO2.

    – A variety of possible approaches to remediation exists. If active semi-original research is undertaken on all reasonable approaches, several of them will almost certainly become technically and economically feasible.

    – Regardless of whether any specific approach works out, all that original research will pay for itself in spin-off technology, even if it turns out, by hindsight, that CO2 remediation wasn’t necessary.

    – All that money spent on research will act as an economic stimulus, while supporting a larger base of literate, educated people.

    • lurker, passing through laughing

      AK,
      Interesting post.
      Can you give some examples of technology that developed the way you described?
      No snark or gotcha’s intended.

      • I don’t know whether you’re talking about directed development or spin-off, but the former would include the space program and much of the military technology developed during the Cold War, while the latter would include, at least, the Internet, which AFAIK developed from military technology envisioned as producing a redundant communications network for battlefield use (ARPANET).

        Note that I don’t have time to create a properly referenced position paper, this just summarizes my position in response to the question posed.

      • “We can’t be sure that dumping of fossil carbon into the atmosphere is the primary reason for increasing pCO2. ”

        Wrong, its likely the most certain of the metrics we have.

        “Still don’t have time for much research,”

        Well, that about explains it.

      • Wrong, its likely the most certain of the metrics we have.

        A very popular lie, but still a lie. We don’t have any metrics beyond a rough correlation between emissions and increasing pCO2. Unfortunately, the increasing emissions also represent a rough proxy for any sort of increasing industrial development, including “whaling and overfishing, swamp/wetland drainage, expansion of irrigated mechanized agriculture, deforestation, and a host of others I’m too busy to think through and list”.

        And please don’t quote isotope studies to me, those just indicate the proportion to current CO2 that comes from fossil sources, not the reason the rest of the system didn’t respond to increased pCO2 by increasing uptake. Obviously it did to some extent, since an amount representing under half of total emitted fossil carbon remains in the atmosphere, but why it didn’t take all, or why it took any, are lost in the details of the complex ecological interactions involved in the carbon cycle.

      • Still don’t have time for much research, but a quick Google turned up NASA spin-off technologies at Wiki.

    • Remediation introduces new external forcings.

      While a system with one large and many small external forcings is unstable, one with two large external forcings tuned to one another is disastrous.

      Ask your plumber about having two working pumps running at the same time in a recirculating flow system for an explanation of why. A competent hydrologist could also explain it.

      • Remediation introduces new external forcings.

        No it doesn’t. CO2 is CO2. It’s a well-mixed gas, and differences in location between emission and uptake make no difference to any “forcing”, either via the Greenhouse effect or any other.

        This is unlike dumping sulfur oxides or aerosols to produce a cooling to offset the proposed Greenhouse warming. That would be subject to the objection you’ve raised.

      • AK | October 9, 2012 at 2:37 pm |

        We’re not in total disagreement. Clearly, dumping contaminants to offset CO2 increase is a second external forcing.

        Clearly, remediating CO2 emission prior to well-mixing (at source, before emission), reduces the initial forcing without becoming a forcing itself.

        In atmosphere, post-emission remediation? I’m a natural skeptic, so I’m uncertain I buy entirely the argument that it is not in itself an external forcing. I’d need more convincing.

      • @Bart R | October 9, 2012 at 9:46 pm |

        OK, it seems obvious to me, the sort of thing I dismiss without wasting time on, but since you ask, I’ll try to make a clear intuitive argument.

        The natural ecosystem produces enormous positive and negative CO2 fluxes, to use the correct technical terminology, differing by location in time and space (over the year). Inter-annual variation (usually attributed to ENSO) can be as great as the overall annual increase in the decade-scale average. The human contribution is a small fraction (~3% IIRC) of the total positive flux from all sources. The total negative flux almost balances this. (I don’t have time to provide references, but the requisite articles have been discussed here in the past.)

        Variations during the year, and from one location to another, make only a very small difference in localized CO2 concentrations, thus to the Greenhouse effect as well as other forcings of the ecosystem. (I’m not convinced the “climate” threat is the most important potential risk of elevated pCP2. Nor ocean acidification. Direct effects on ecosystem balances IMO have a larger probability of causing significant harm to society.) I don’t have references to hand for this statement, but I researched it at one point when the subject came up.

        Given that the effect of human emission (positive flux) and remediation (negative flux) is distributed over the entire planet and multiple years, small differences in spacial location or time within the year will make no more difference than differences in the larger natural sources and sinks.

        Of course, this is entirely different from the delay I’m proposing between emissions (now) and mature remediation technology (2-3 decades). There would be an intervening period of higher pCO2 with increased Greenhouse effect and other (IMO more important) risks. (Relative to immediate drastic mitigation.) My point is that mitigation is politically and technically unfeasible in less than this time frame, and carries the risk that it might not fix the problem for the reasons I’ve mentioned.

        We’re looking at a 3-5 decade maturity for any proposed solution. IMO the one I’m proposing is far superior than one based on mitigation for the reasons described. It also removes any concern about “centuries long” increases in pCO2, and offers the continually improving life-style most of the world demands.

        And the risk is (IMO) smaller than trying to impose political solutions to drastically cut emissions at the source, which would almost certainly lead to higher energy prices, thus to reduced lifestyle and political instability. People just won’t stand for it, and shouldn’t have to.

    While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear.

    The first clause contradicts the second. If the first is true, then the long-term picture is unclear. The future will be as variable as the past.

    • lurker, passing through laughing

      Matt,
      +1. You hit nail on head of the basic problem of the AGW community. They do not know what they are claiming as truth is in fact true, but they know for sure that it will be very bad.

      • Latimer Alder

        @lurker

        You are absolutely right to say

        ‘They do not know what they are claiming as truth is in fact true, but they know for sure that it will be very bad.’

        but you forgot the qualifier

        ‘…and far worse than we thought. More research is needed’

    • The uncertainty is anything between 1C and 5C warming per doubling of CO2. We will more than double it. Either way that’s a profoundly changed Earth.

      • Profoundly changed Earth??? LOL- if a 1C change occured over the next 100 years would earth be profoundly changed? HOW????

      • Even 1 degree C may make the planet warmer than it has been for millions of years. But of course the warming won’t be limited to 1 degree C if we burn all the carbon.

      • lolwot,

        there were Hippos in the Thames in the Eemian. Their bones are found in London today. That is a lot more than 1 degree warmer, a lot less than a million years ago.

      • Yes higher latitudes were warmer in the Eemian, but see

        Paleoclimate Implications for Human-Made Climate Change
        James E. Hansen and Makiko Sato
        http://www.columbia.edu/~jeh1/mailings/2011/20110118_MilankovicPaper.pdf

      • Further to Gareth’s and Lolwot’s posts: According to the British Geological Survey (BGS, a UK government agency) there were rhinos, elephants and leopards as well as hippos in the Thames basin during the Eemian period (130 to 117 thousand years ago). (BGS, Holiday Geology Guide to Trafalgar Square, 1996). There were humans in Africa at the time.

    • If the first is true, then the long-term picture is unclear.

      You left off a qualifier: “profoundly changed Earth.”

      It is possible to be uncertain about the “most important potential impacts” (say, level of sea rise) and responses (say, effectiveness of a carbon tax) and still be certain that a “profoundly changed Earth” will result – at some point in the future – from BAU w/r/t ACO2.

      If you don’t want to address his question, then don’t. If you don’t agree with his assumption that a “profoundly changed Earth,” is clear, so be it. Argue with that assumption.

      • Joshua

        It is possible to make any number of claims without any of them being factually correct. Does it matter if the claim is factually inaccurate or at a minimum not supported by observable evidence?

      • Rob –

        Does it matter if the claim is factually inaccurate or at a minimum not supported by observable evidence?

        Of course that matters. If you disagree with what he considers to be accurate, so be it – and argue that point if you want. But it is important to clearly distinguish the lines of disagreement, not base arguments on logical inconsistencies that don’t exist.

        If you don’t agree that a profoundly changed Earth is clear, then argue that point. But acknowledging uncertainties in itself does not disprove a belief that a profoundly changed Earth is inevitable. I consider making such arguments to be an invalid exploitation of legitimate expression of uncertainty. It seems invalid to me to on the one hand criticize a lack of acknowledgement of uncertainty at the same time as saying that acknowledgement of uncertainty contradicts concern about a clear profound change. This is one of the problems I have with “skeptics” (as opposed to skeptics) in their approach to “uncertainty.” That, along with a fairly ubiquitous mis-representation when climate scientists do acknowledge uncertainty (think of the bogus “they said the science is settled” meme).

      • Joshua

        Is making a claim that sea level will rise at a greater rate than it is currently, but being unable to state when or by how much a relavant claim or simply spreading unsupportable propaganda? Is writing that there will be “profound changes” but not describing exactly what these will be by when ore than spreading propaganda?

    • Steven Mosher

      “The first clause contradicts the second. If the first is true, then the long-term picture is unclear. The future will be as variable as the past.”

      Actually it doesnt.

      “While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming, the long-term picture of a profoundly changed Earth is clear.”

      The first clause.

      1. There is deep and persistent uncertainty about the most important impacts.
      2. There is deep and persistent uncertainty about responses.

      Both of these statements are about the state of human knowledge WRT
      A) Impacts
      B) Responses.

      The second clause.
      the long term picture of a changed earth is clear.

      This is a statement about a projection of the state of the earth.It involves human knowledge. basically Revkin is saying that we know there will be pervasive changes, but the IMPACTS and our responses to those IMPACTS is uncertain.

      So, long term, given the best science we have today, we can predict a world that is warmer in the future. In fact, it is very likely that if we continue to dump C02 into the air that we will see a earth that is warmer than any other human has seen, clearly warmer than any modern civilized industrialized human has seen. That will be a profound change. which means the change will be pervasive and intense.

      What are the impacts of that pervasive change? lots of uncertainty there. Where will the warming happen? where will sea level rise be worst? what will be the impact on regions that are cold? what will happen to plant growth? the oceans? lots of uncertainty in these details. And the uncertainty of response is not even related LOGICALLY to the vision of profound change.

      When somebody thinks that two sentences are in contradiction, they usually are not thinking or reading logically. Reduce the sentences to their logical form. Then show the contradiction.

      • Sorry, increased CO2 does not necessarily imply ‘profound’ changes to anything. Nonetheless, the plant kingdom seems to have profoundly responded.
        ===========

      • You care more about plants than people. I like plants, but I like people better. I should say I like most plants and most people. I don’t like weeds. Some people are like weeds.

      • Classic Max,

        You like “people better”, except of course those people you consider to be weeds.

        Love like yours I can do without.

        At least you deserve kudos for reminding us what so many people advocating for action to address climate change truely are after – a world with less people. With the caveat that they are among those who get to stay.

      • I wasn’t implying kim is a weed. He just likes plants, including weeds.

      • Max,

        I did not make any claim of you implying kim is a weed. I simply pointed out the irony, and probable hypocracy, of your statement about liking people.

      • Steven, why all the thinkin & writing, when you just wrote this…

        he had nothing of relevance. basically a small number of records from NWS

        the guru had nothing, What, me worry. Got my two shoes too.

      • Steven Mosher

        Explaining ‘why’ all the thinking and writing is a far different question from explaining the facts of the actual case. Diversions into motives and speculations about internal states are entertaining but not instructive.

        Our suspicion and ONE OF THE REASONS we asked for the data was that we supposed that Jones did nothing of value with the data.

        Skeptics, of course, thought that Jones manipulated the data. baaad evil Jones. believers thought that jones performed some great feats of science with the data. Auditors suspected that he did very little with the data.

        Now of course Jones has taken OUR position. he does nothing to the source data. he collects it. he runs his code. he outputs the answer.

      • Steven,
        Will we ever know what the actual recorded data was, before being transferred to computer files for use once the written records had been compiled? How large was the budget to transfer all of this information? It must have been in the millions. What Reason, could Jones, have possibly had to just ‘dump’ (question yet to be asked it looks like) these records? It was a BIG decision and from what I read he did it on his own… adjusted numbers. House built on sand is more like it. Science is still trying to understand the trick but the magician ain’t talking. If obvious questions such as this aren’t asked and answered; there is nothing to debate. AGW science is irrelevant.

      • Phil Jones: wanted to ‘save space’…
        How much ‘space’ (in cubic feet, or meters) did he end up saving?
        He must have had some number in mind too.)

      • No, StevenI think the reason skeptics dislike Jones, and alarmists liked him, was because he hid the tax-funded data from skeptics and gave it to alarmists, in an attempt to suffocate science with politics.

      • Moser says

        “Now of course Jones has taken OUR position. he does nothing to the source data. he collects it. he runs his code. he outputs the answer.”

        Can you answer how to adjust/justify the shrinking/changing raw data set ?

      • You write a large amount of bologna.
        There is not reliable evidence that there will be pervasive changes to the environment or that the net changes will be negative overall over the long term. There is also no evidence that a world that is slightly warmer over the next 100 years will be profoundly different for humans. You write unsupportable propaganda.

      • Steven Mosher

        1. There can be no EVIDENCE that there will be pervasive change. There is only a prediction based on the best science we have. Evidence relates to the past. evidence of the past supports the science of the present whcih makes predictions about the future.

        2. I made no claim about the net NEGATIVE changes. the impacts are uncertain.

        3. If the prediction of 2C warming holds true, and there is NO Theory or science that suggests it is wrong, then the human species will see a climate that it has not experienced before. That change will be pervasive.
        will it be good for all? bad for all? net positive ? net negative? dunno. thats much less clear than the science that predicts the warming

      • Steve

        When you used the word “pervasive” you were indicating that there would be net negative consequences.
        The definition from Oxford:
        Pervasive- adjective
        (especially of an unwelcome influence or physical effect) spreading widely throughout an area or a group of people:

        Regarding the 2C of temperature rise that you believe is inevitable- over what timeframe to you believe this change inevitably will come about? There is most certainly differences of opinion within the science community.

      • As usual, Steven Mosher is right.

        ” … people with an agricultural background point out that northern latitude areas that cannot grow certain temperature sensitive crops today, whereas in past years, such as the MWP, the same crops could be grown … ”
        ________

        I’m skeptical. What crops would those be?

      • Trees Max, and berries,grasses

      • Grapes

      • I laugh every time someone brings up the MWP being so warm grapes were grown in places grapes can’t grow now.

        Grapes aren’t very sensitive to cold. Grapes are grown in Upstate NY. Grapes are grown in Scotland. I doubt there every was a time in the past few thousand years that grapes wouldn’t grow in the NY and the UK.

        I don’t know what kinds of berries and trees you are talking about, but some trees (e.g., coconut palms) don’t grow in NY and the UK now, nor would they have in the MWP.

      • Are you saying temperatures will be higher than those experienced by people during the Roman Warm Period and the Medieval Warm Period? Not a rhetorical question. Just asking.

      • “Are you saying temperatures will be higher than those experienced by people during the Roman Warm Period and the Medieval Warm Period? Not a rhetorical question. Just asking.”

        They might already be higher.

      • lolwot – people with an agricultural background point out that northern latitude areas that cannot grow certain temperature sensitive crops today, whereas in past years, such as the MWP, the same crops could be grown in those areas disprove Mann’s hockey stick temperature reconstruction.

        Tony B has commented previously on that subject.

      • Steven Mosher

        Yes. Looking at the reconstructions i’d wager that at current temps there about a 50% chance that it was warmer in the periods you mention. Add, 2C to the temps we have today and we transgress a boundary that civilized humans have not seen. Our civilization is an adaptation to the environment. We will be changing the conditions of our existence.

        1. we should not do this without some due diligence.
        2. we should not react out of fear.

        But, admitting that we are in fact changing the conditions of our existence is the key to having a fruitful dialog

      • @Steven Mosher
        Can we “admit” that we are changing the conditions of our existence, when we don’t yet know it?

      • Steven Mosher

        When you mention human-induced future warming of 2C, you are making a leap of faith.

        Past warming has been 0.7C (since 1850), and a significant part of this has not been anthropogenic (IPCC, with an admitted “low level of scientific understanding of solar forcing, says 7%, other sources say 50%).

        From this and the CO2 levels in 1850 and today, we can calculate the CO2/temperature response for 2xCO2 at between 0.8C and 1.5C.

        It is unlikely that we will double atmospheric CO2 above today’s level (=784 ppmv) anytime before the next 150 years (figure it out), so this means we might see 0.8C to 1.5C warming over the next 150 years.

        And added CO2 concentration from human emissions is constrained by the availability of fossil fuels to an absolute maximum level of a bit over 1000 ppmv, when they are all gone.

        This means we could have an asymptotic absolute-maximum-ever AGW of 1C to 2C when all fossil fuels are gone..

        And, since this would not occur for at least 150 to 200 years, we’d have plenty of time to adapt.

        Max

      • TomCat

        You ask Mosher

        Can we “admit” that we are changing the conditions of our existence, when we don’t yet know it?

        To nitpick, we “change the conditions of our existence” simply by existing, breathing, getting older, etc. So, in a nitpicking sense, Mosher is right by definition..

        But the question is whether through the emission of GHGs (principally CO2) we are “changing the conditions of our existence” perceptibly, in a net negative or positive way and, if so, is this change likely to have dramatic results?

        Perceptibly: Probable but not validated by empirical data
        Net negative or positive (Judith’s “winners and losers”): Unknown, some general indication that higher CO2 levels and lightly higher temperatures will have a net beneficial impact on overall crop yields..
        Dramatic results: Unlikely, based on past CO2/temperature response and results

        Mosher may have an other assessment on this.

        Max

      • “When somebody thinks that two sentences are in contradiction, they usually are not thinking or reading logically.”

        It’s hard to be more wrong than that sentence, when taken as a general rule. And it’s not much better in this particular instance.

        Generally, there is a whole lot of bad writing and poor logic, and not just on this blog. It’s everywhere. Mosher himself frequently complains that comments here contain contradictory sentences. So stating it as a general rule is a non-starter.

        And in this particular case, I don’t think any of the comments, including Mosher’s, get the comparison right.

        The first clause is “While persistent and deep uncertainty surrounds the most important potential impacts from and responses to greenhouse-driven global warming….”

        The second, allegedly contradictory clause is: “…the long-term picture of a profoundly changed Earth is clear.”

        The uncertainty is to the “potential impacts and responses” to global warming, while the certainty is to the long-term picture of a profoundly changed Earth is clear.”

        Whether the two are contradictory depends on what Revkin meant in the second clause. If he meant merely that there would be profound changes in the Earth in the future, I don’t think that is contradictory, but it is also not terribly informative. Who doesn’t expect significant changes in the Earth over a long period of time, with or without CAGW.

        But his use of the word “picture” suggests some understanding of what those profound changes will be. And that they will be “profound” suggests they will be intense, ie. negative. That would contradict his first point regarding uncertainty of impacts and responses.

        On the whole, Revkin seems to be saying that we don’t really know what anthropogenic CO2 emissions will do to the Earth, or how mankind will respond, but the bet right now is that it will not turn out well. (Notice the last sentence of the quote “…to limit economic and environmental regrets.”) I just don’t think he said it very clearly.

      • Steven Mosher

        very simple gary. reduce the sentences to propositional logic and show the contradiction. You cannot. That is why you blather.

      • GaryM

        You are right and (this time) Steven Mosher is wrong.

        Revkin contradicted himself.

        No “blather” needed.

        Max

      • MattStat/MatthewRMarler

        Steven Mosher: So, long term, given the best science we have today, we can predict a world that is warmer in the future.

        I have argued that the best science we have today is full of inadequacies; we can predict a world that is warmer principally by ignoring complications, and we can not tell now that the ignored complications do not matter. The state of knowledge that we have right now does not exclude the possibility of cloud feedbacks that limit any warming that might occur. The only way you can read the sentence so that the first part does not contradict the second is to construe the first part in such a way as to ignore many of the uncertainties.

        Now that I have read the comments, I have construed that sentence in multiple ways. There is room for disagreement about what exactly the phrase ” uncertainty surrounds the most important potential impacts from and responses to” includes and excludes. However, if there is uncertainty over potential impacts, then it can’t be clear that profound change will be caused.

      • Steven Mosher

        1. the fact that the best science has problems is a near tautology.
        2. profound MEANS pervasive. Our best science tells us that if we change the atmosphere it will have PROFOUND, PERVASIVE consequences. what happens in vegas stays in vegas. what happens in the atmospher effects the entire system. GET IT. pervasive.

        Lets look at your last statement. If there is uncertainty over impacts, then it cant be clear that there will be profound change.

        lets take something simple. I tell you you are going to win 500 million in the lottery. That will be a profound change. But I have a great deal of uncertainty over the impacts. What will you do with the money? blow it all on nonsense? start a foundation? spend sme and save some. ruin your life? So I have uncertainty over the impacts, but its clear that there will be a profound change. lots of change.

        The best science is clear ( and imperfect BY DEFINITION) if we change the atmosphere the change will be profound. pervasive.
        However, we dont understand all the details and the impacts.

      • MattStat/MatthewRMarler

        Steven Mosher: lets take something simple.

        Let’s not. Let’s stick with things at least as complex as the climate, with uncertainties at least as great as climate uncertainties. Uncertainties in climate science are such that pervasive climate change may not occur; we may have a continuation of the fluctuations within the range of the last 2,000 years.

        It is not merely that there are uncertainties, as always with science, but that the uncertainties in climate science are of large enough magnitude that they can not be asserted to be too small to matter.

      • Steven Mosher

        You are falling into the logic trap of defending Revkin’s “picture of a profoundly changed Earth” by equating the GCM simulation outputs cited by IPCC with “best science”.

        Let’s go back to Feynman’s definition of “best science”.

        “Profound” means “deep” – in this case it means “having strong consequences”. And the implication is that these are “negative” (so the future US President has to consider taking actions to mitigate against them, rather than rejoice that they are happening).

        We (including you plus Revkin) have no earthly notion of whether or not human GHG emissions will result in profound negative consequences. It is pure conjecture. It is a counter-intuitive “best guess” (maybe), but not “best science”.

        I could posit that we will have an invasion by extraterrestrials, which will “profoundly” change the Earth (adding Revkin’s disclaimer clause that we really don’t know whether this is true or not) but “the long-term picture of a profoundly changed Earth is clear”, so the next US President should consider taking “no-regrets” actions to install anti-extraterrestrial invasion systems and devices (in the USA and possibly even all over the world).

        I could even say that “best science” tells me there has to be life on another planet somewhere, that statistically it is obvious that at least one planet has intelligent life that has been around longer than we humans, ergo an extraterrestrial invasion is certain and could well occur imminently.

        Just like the above argument, Revkin’s question was loaded (hence illogical) and contradictory. And the “best science” argument is weak.

        Max

        .

  43. Let me reword Revkin’s loaded presidential debate question slightly

    CNN Moderator Mr. President, Governor Romney, we don’t really know whether or not human activity has caused any substantial warming, but we do know from climate scientists that if whoever gets elected does not do something very drastic and costly about it we’ll all die a horrible death.

    So what do you two see as the best mix of achievable policies to limit environmental and economic regrets?

    Obama: I have always been in favor of an “all of the above” climate policy, including a carbon price with cap and trade, crippling EPA regulatory restrictions on the coal plus oil and gas industries, fewer incentives for exploratory drilling, no further drilling on government lands, no Keystone pipeline, more taxes on the rich, etc. The science is settled, as my science czar has advise me. Under MY administration, temperatures have, indeed, sunk, as have the rates of sea level rise; I assume full responsibility for these fortunate trends and will continue my policies, which have led to them, including MY Affordable Care Act, also known as “Obamacare”. My opponent would lower taxes on multi-millionaires, even though this could have a dramatic impact on our nation’s budget and our war against climate change.

    [The prompter shows a flat approval line among undecided voters, with women voters scoring slightly higher than men voters. The line moves up slightly when the President describes how his policies have stopped climate change.]

    Romney I believe in an “all of the above” energy policy to ensure that Americans continue to enjoy reliable and readily available energy sources in the future. I do not know enough about climate science to make any real statements regarding my administration’s policy regarding climate. I do not believe that “the science is settled”, as my opponent does. I will not, in any case, raise taxes on anyone to fight against climate change, but if I am advised that there is a real and immediate danger to the welfare of US citizens from climate change or any other internal or external threat, I will look at all possible ways to avert this threat, using the means that are at my disposal as US President.

    [The prompter shows a flat approval line among undecided voters, with men voters scoring slightly higher than women voters. The line moves up decidedly when Romney states that he will not raise taxes.]

  44. An international agreement should be forged to place extraction caps on existing oil, gas and coal fields, to limit extraction. Also to mandate that any newly discovered oil, coal and gas fields shall be automatically locked until at least 2050, by which time there can be a reassessment.

    • lolwot

      What would be the reason that the nations with these resources would agree to such a treaty? LOL- Try to be realistic.

      • That would be part of negotiations. There could be compensation of some kind for example. Locking away the fossil fuels don’t mean it will never be used, it just means it will be used more slowly over time, which from a finite resources point of view is more sensible anyway in my opinion.

      • lolwot- so who is going to pay the USA for not developing our fossil fuel resources today to the maximum extent possible???

        Answer- nobody

        Again, try to address the real world as it is in reality and not as you may wish it existed in some fantasy

      • As Ottmar Edenhofer, head of IPCC WG3 said in an interview: “Basically it’s a big mistake to discuss climate policy separately from the major themes of globalization. The climate summit in Cancun at the end of the month is not a climate conference, but one of the largest economic conferences since the Second World War. Why? Because we have 11,000 gigatons of carbon in the coal reserves in the soil under our feet – and we must emit only 400 gigatons in the atmosphere if we want to keep the 2-degree target. 11 000 to 400 – there is no getting around the fact that most of the fossil reserves must remain in the soil…..But one must say clearly that we redistribute de facto the world’s wealth by climate policy. Obviously, the owners of coal and oil will not be enthusiastic about this. One has to free oneself from the illusion that international climate policy is environmental policy. This has almost nothing to do with environmental policy anymore, with problems such as deforestation or the ozone hole.”

      • lolwot, this guy?
        http://en.wikipedia.org/wiki/Ottmar_Edenhofer

        Why would i believe what he says? The professorship of Economics of Climate Change at the Technical University of Berlin? At a technical university?

      • lolwot

        Again, you seem to be in some fantasy world. In the real world who cares what Ottmar Edenhofer wrote or said. In the real world it is a very, very small number who care about his opinion, yours or mine.

        Nations will not restrict the use or development of fossil fuels unless there is a clear cost effective alternative that can be adopted OR unless there is clear unambiguous evidence to demonstrate that the world is being harmed by the use of fossil fuel.

        There is no clear unambiguous evidence of this harm. There is fear of potential future harm, but nothing clear to demonstrate that science really understands the system. Look at the 3 questions I asked at 9:14 and try to honestly answer them. The fact that they can not by clearly answered is the problem with your position!

      • My proposal is realistic. A cap at source is the easiest and most efficient solution to reducing emissions. While negotiations would be difficult, they are by no means impossible. Nations have already in the past agreed not to extract from Antarctica and existing cap systems are already applied to resources such as fish.

        An international agreement to place caps on existing fossil fuel reserves and lock newly discovered ones is an agreement I am sure the world could largely come to, especially if done in stages. Starting off with a low cap, eg 10% and increasing it slowly in subsequent meetings.

        Even if some countries refused it would still be a useful to have widespread adoption. There could be further measures to sideline countries that disagree by placing restrictions on the purchase of fossil fuels from those countries.

      • lolwot

        Your idea in completely unrealistic because there is no source of funds to pay countries to not produce the fossil fuel resources they have and there is every motivation for those countries to exploit those same resources in order to gain a source of funds.

        It is much easier to gain an agreement to not exploit a place like the south pole where it is economically unprofitable to exploit the resources there anyway. Please lay out you case as to why Russia, the USA or even Mexico should produce less. Why do you think there was no agreement in Kyoto when people believed the information available at that time?

      • The compensation wouldn’t be “full”. It might even only be 5% of what the country would have got for not locking the resource. After-all the country still has the resource to use at a future date, eg post 2100.

        Compensation means giving certain countries something to get the negotiations to succeed. Perhaps some short-term financial incentive, or perhaps something else.

        “Please lay out you case as to why Russia, the USA or even Mexico should produce less.”

        To reduce the risk from climate change. Eventually there may happen to be an alignment of leaders of such countries who have the moral courage to reach an international agreement.

        Or more likely I expect this will all be prompted if or when a climate disaster happens. Going to be hard to do nothing about emissions if the population of somewhereistan consider foreign emissions an act of war.

      • lolwot

        Whether the compensation is partial or full, you have no source of funds to pay anyone anything. Try to be realistic and either determine where the funds will come from or give up on a failed concept. The amount of compensation required would be tremendous worldwide and there is no funds to pay for such an idea.

        You write that these countries should forego current sources of revenue so that they may “reduce the risk from climate change”. How would you suggest that they measure whether or not their sacrifices have been successful when you do not even know what the actual negative impacts of a warmer world will be?

      • Success is measured by the limitation of the CO2 rise.

        Compensation would be paid via a levy on all countries in the agreement.

      • lolwot

        Ok, so now we are taking a journey through lolwot’s Fantasyland. In Fantasyland independent countries who do not have all the resources they want for their citizens will agree to pay countries such as Russia, Iraq, the USA, etc. to not mine or pump fossil fuel reserves.

        It the real world, countries will continue to mine and pump their resources as long as someone is willing to pay more for them than it costs to get the resources to them. I would seriously prefer Fantasyland however. Life would be so much easier. We’d have unlimited money and could alway spend whatever we wanted.

      • lolwot

        RE “My proposal is realistic.”

        you peg the laugh meter with that one. Seriously, what do you do in real life? What makes you believe that anyone involved in the discovery and extraction of natural reasources is going to agree to just stop? And exactly how are you going to convince the average taxpayer in any of the developed nations to agree to a transfer of their wealth to someone else?

        I’m a taxpayer. Convince me.

      • Rob Starkey,

        “Your idea in completely unrealistic….”

        Well that’s just plain unfair. We aren’t talking about the real world here. We are talking about the world as it exists in the mind of whatever progressive in proposing whatever inane policy du jour happens to be most popular among them at the time.

        There is no difference to a progressive between the real world, and the world in their fevered brains.

        That is why “we can’t explain the warming without CAGW” is proof positive to them that CAGW is real. That is why Obama could say with a straight face that the day of his inauguration would be the day the seas began to recede. And Jerry Brown can by fiat make automobiles more fuel efficient in California by a date certain.

        Reality? We don’t need no stinkin’ reality!

      • of course none of you understand, you all blindly dismiss the threat of CAGW.

        World leaders however might think differently and therefore might come to an agreement to cap emissions.

      • lolwot and Rob Starkey

        I have been following your exchange with interest.

        Of course, the notion is hare-brained that any political leader of any nation would act against the immediate interest of its taxpaying citizens in order to do what a few egghead climatologists consider “the right thing to do to save humanity from a wholly imaginary long term threat”.

        This is especially true of countries like China and India, who have totally different priorities than worrying about a “rich white man’s” guilt-driven obsession with CO2.

        It ain’t gonna happen, lolwot, so stop dreaming.

        Fossil fuels will continue to be used to improve the overall welfare of mankind (as they have since the Industrial Revolution), until something more cost competitive comes along.

        Those nations with fossil fuel resources will extract and exploit these as long as this is the most economical thing to do.

        And, as a result of human ingenuity and the free market (which got us where we are today), new technologies will come along that will eventually replace fossil fuels for many of the lower added-value end uses, such as electrical power generation or transportation. This process will not even require lolwot’s hare-brained scheme.

        Max

        PS Politicians may try to implement taxes on fossil fuels or anything else they can think of to increase their spending ability and power, but that is another story entirely.

      • lolwot (stating the views of many CAGW alarmists says):

        of course none of you understand, you all blindly dismiss the threat of CAGW.

        Max (representing those people who understand how the real world works) says:

        Fossil fuels will continue to be used to improve the overall welfare of mankind (as they have since the Industrial Revolution), until something more cost competitive comes along.

        Max is absolutely correct. It is so obvious it shouldn’t be necessary to state it.

        If the CAGW alarmists are genuinely concerned about CAGW (as opposed to using it to push other ideological agendas), they need to enthusiastically advocate removing the barriers to cost-competitive, low-emissions energy. It is those of ‘Progressive’, Left, Green ideological persuasion that have caused the barriers to be implemented. Therefore, if they are so desperate to reduce emissions, they should be leading the charge to allow them to become cost competitive.

        Why can’t lolwot and those who share his views understand this?

    • lolwot,

      What a dumb and ignorant comment. It’s the sort of rubbish CAGW alarmist write all the time. It reveals how it would be stupid to take any notice of anything they say.

  45. antisesquipedalian

    warmer is better !! always has been, always will be (for man, that is). The earth could care less. don’t spend one dime of my money on Global Warming prevention.

  46. The cost of adaptation versus the cost of (unachievable) co2 reduction.

  47. All, the costs, that is. Not just financial but issues such as food security etc.

  48. What do you see as the best mix of achievable policies to limit environmental and economic regrets?

    The ‘best mix’ of achievable climate policies remain what they were before we began to consider climate issues, as policies flow from the general principle to the particular application of the precept.

    What are the best policies to limit enviornmental and economic regrets in general? I judge ‘best’ by what in general removes the most misery and produces the most satisfaction for the most people, an Economist’s definition; in no particular order: Democracy, Fair Market Capitalism, Education, Scientific Research valued for its own sake, Moral Leadership serving personal Freedom, Minimal Government to achieve the necessary functions of governance, Separation of Church (or other institution) and State.

    In particular but in no particular order, informed conservation of biological diversity, development of public taste for a thriving ecosystem, responsiveness of governments to the will of individual human beings not of corporate fictions, levelling the playing field by privatizing the carbon cycle, enlightened application of the principles (by which I mean from Newton’s Principia) of Science to questions of climate science, and payment for harms by those who cause them.

    When it is asserted by biologists that we may expect to see a loss of a substantial fraction of the biological diversity of the planet in the next quarter to half century, and the biologists present substantial evidence for this proposition, we ought recognize this to be a serious issue, regardless of our conclusions separately about climate. Moreso, as we must recognize that climate change for the next quarter to half century is already committed, and we can do nothing to climate to avert its influence within this event. Our concern ought be the next millennium after the next half century, and the subsequent question of stabilization of biodiversity. That is, if we care about things more than 50 years in the future. But whatever else, we can assign fault in this, and we can demand penalties be paid for the losses, under the precept of fundamental justice. Why? Because a world where the only animals living in the ocean are jellyfish is a pretty pathetic place compared to what we once had, and we’re entitled to extract a pound of flesh from those who make it so.

    When corporations or cults or foreign countries so overexploit a resource as to collapse it, invariably we know there were voices of individuals warning the world this was coming, and individuals making up the democratic majority expressing the will to avoid this collapse, and we see governments continue to listen to corporations or cults or their own inertia rather than immediately and democratically changing course. This failure of democracy, this demonstration that some governments are not so democratic as they claim, is an indictment, a finger pointing at the very incestuous relationship between institutions like churches and corporations and state. Even — and especially — religious people and businesspeople ought recognize there is no benefit ultimately in a government that has lost its democratic right to govern through serving too much a handful of religions or a handful of industries.

    When substantial subsidies (implicit, explicit, through direct expenditure or tax expenditure, infrastructure favoritism or procurement favoritism) side-by-side with failure to price a diminishing resource, the economy is running under false metrics, and will crash over and over again until it ultimately fails. The Carbon Cycle has the properties of scarcity, rivalry and excludability that demand it be privatized to profit market players and stabilize the resource, just as happened with bandwidth in mobile communications. Moreover, the revenues of this privatization must go to private individuals fairly, per capita, ideally through something like a payroll entry reducing income taxes.

    All of this can be achieved without additional command-and-control regulation; indeed, these measures would reduce the command power of the state and replace it with the democractic decisions of individuals. Would it not be best then to encourage the fullest possible information of individual players in the economy by the best possible factual and scientific education, with a sound grounding in logic and reasoning, mathematics and technology?

    I cannot help but believe that from such policies, we would see a desire for more just outcomes and better results than we see now. And even if the democratic outcome of a fully informed populace expressing its will in a well-balanced Market led to increase in CO2 levels and in AGW, and led even to catastrophe, then at least it would be by the democracy of all the people, not the greed of the few.

    • What do you mean by privatization Bart? It appears to be double speak for confiscation.

      • johnfpittman | October 9, 2012 at 11:23 am |

        I mean by privatization exactly what privatization means.

        Here’s the first two distinct Google hits for “privatization dictionary definition”:
        http://www.thefreedictionary.com/privatization
        http://www.merriam-webster.com/dictionary/privatize

        The Taoist philosophy that the strongest government is virtually invisible, that so much function of an economy as possible remains in private hands, approaches the Capitalist ideal of the fair and open Market procuring maximum efficiency in allocation of scarce, rivalrous, excludable resources. This coincides with Minarchy, the ideal of minimal government for efficient conduct of state administration.

        In the particular case of the carbon cycle, the closest and best argued proposal for privatization I’ve seen is the Fee & Dividend system as proposed by the Citizen’s Climate Lobby (http://citizensclimatelobby.org/node/398).

        I should note, I don’t fully endorse all aspects of this particular proposal. It differs from how I would do it, as does the British Columbia Revenue Neutral Carbon Tax (successful and growing in popularity for 4 years now), the Australian Pricing Mechanism, or any of the Cap & Trade schemes or various carbon taxes that return nothing to the owners of the carbon cycle. For one thing, I’d let the price of CO2 emission float to maximize returns to owners of the carbon cycle: every citizen, per capita.

        In this sense, carbon cycle privatization ends the confiscation of the carbon cycle by the few who pay nothing for it from the many who own equal, undiluted and inalienable rights to it.

        See? Simple Capitalism; the Market in action.

      • Bart, thanks. I do see wrt to US laws, you are proposing confiscation and nationalization of resources, since many of the fossil fuels are owned by individuals who have leased their mineral rights to corporations. The US does the same for fossil fuels, as well as land use for renewables. Those with leases to the mineral rights have the rights, say EXXON, and it is theirs as well as the infrastructure they installed. Citizens can and do buy these stocks and thus own these corporations. Your proposal would be seen as a communist or socialist confiscation of property (personal) rights, confiscation of rights and properties by the corporations, not as privatization, but nationalization. That they would pay for the infrastucture, etc, after the fact, would still be considered nationalization and confiscation by denying them the rights to their property and lease.

        I will read the link when I get a chance to see if there is something I think merits consideration. But trying to redefine confiscation as privatization seems more than a stretch. It defies current definitions of property and property rights, at least for the US. I could see that if the US did it for unleased, and paid for the infrastructure and development, then did what they wanted; this could be done. However, this would be local change and not a world change. Thus it would accomplish little unless all subscribed to it. The concept of owning a carbon cycle is not one that is recognized that I know of, and does appear to be a method to re-define confiscation. That said, Citizen’s Climate Lobby may have a useful mechanism.

      • The problem with the British Columbia Neutral Carbon Tax (besides its inherent dishonesty, having as it does no chance in hell of remaining neutral), is what level to set it at. Which implies proper knowledge of the costs and benefits , which climate science is obviously not even close to giving us, mired as it is in alarmist propaganda efforts at the hand of governments, the IPCC etc. (This ignorance problem bedevils all approaches to “combating” climate change, not just this one).

        It is also not the case that the carbon cycle has been “confiscated” by the few at the expense of the many. The many use carbon, hence the many would bear the fresh brunt of a carbon tax. If say only fossil fuel companies had to pay the carbon tax, this would simply push up the price of fuel to the many.

      • Memphis | October 10, 2012 at 2:56 am |

        No chance?

        It has written into it a penalty clause that claws back a large part of the salary of the elected member responsible if it isn’t proven to be neutral in any one year, by a fixed date.

        And BC has — and uses successfully — a recall that allows voters to quash changes to taxes they don’t like.

        What’s your argument for ‘no chance’? That you don’t trust democracy? Or that you like the sound of the voices in your head?

        While I agree the level of the BC Revenue Neutral Carbon Tax is too low, and should be set by the Law of Supply and Demand (see, that depends on exactly two experts: the expert who is buying, and the expert who is selling, democratically, at the level of each individual transaction), and that the dividends are mis-directed and should go to every citizen per capita 100%, it’s not like I’m saying they’re there yet. I’m just pointing out there’s more than one viable proof of concept that deflates objections of blowhards who spout opinion out the seat of their pants with zero understanding, experience, or knowledge of such things.

        Also, how can you seriously claim the few don’t benefit disproportionately on the backs of the many from the current Commons treatment of the carbon cycle? How much CO2 do you emit personally on average for commercial enterprises? 70% of us emit less than half of what the other 30% emit in total. Two percent of us make money by emitting CO2, while 98% of us bear the cost. That’s confiscation without compensation. If the fossil fuel companies passed this cost on to the rest of us, we’d find the actual most economically efficient energy resource to use, or stop wasting so much, or conserve, or otherwise express our tastes economically.

        Trying to game the economy by hiding the cost of a scarce resource will inevitably lead to economic collapse. How is that good?

      • Bart R

        Revenue neutrality having no hope of holding up:

        Seizing the salary of an elected member will never be enough to put right revenue excesses. No chance. Government has an agenda of its own, and voting acts only as a minor governor of government. Once a new tax is established, is will slowly and surely creep up due to “necessity” the politicians will say. And no, I don’t trust the voices in your head.

        While I agree the level of the BC Revenue Neutral Carbon Tax is too low
        Agreeing with yourself ?

        and should be set by the Law of Supply and Demand (see, that depends on exactly two experts: the expert who is buying, and the expert who is selling, democratically, at the level of each individual transaction),
        So you are the “two experts” now, hence the agreement mentioned above ?

        The claim that there is is disproportionate gain by the few on the backs of the many from the current Commons treatment of the carbon cycle, is pure bogus. How much CO2 a corporation emits is beside the point; the customers share the benefits too, by virtue of lower costs of the corporation’s products, due to lower costs to the corporation.

        hiding the cost of a scarce resource will inevitably lead to economic collapse. How is that good?

        It isn’t. But in this case putting it into common (not the commons) ownership is not so simple, with government inevitably gaming the system to favor itself – to the approval of those with totalitarian ideals. This though is a valid point (unlike the notion above that corporation benefit disproportionally).

      • Memphis | October 10, 2012 at 12:12 pm |

        That’s an awful lot of assertion.

        You sound like Ned Beatty trapped in Deliverance for eternity, just resigned to taking whatever the government is going to do to you.

        The government isn’t the problem here. You are.

      • Bart
        So you have no answer then. OK.

      • Memphis | October 11, 2012 at 2:19 am |

        Ned Beatty was in therapy for years after playing the role of the victim in Deliverance.

        If you believe you’re always the victim of a corrupt government violating you at every turn, that’s a level of martyr complex beyond any blog commenter’s power to answer.

        Either man up, or seek professional help.

      • Right, so still no answer from Bart, who as a cretinous stalinist thinks governments do no harm. Talk about needing professional help…

      • Memphis | October 12, 2012 at 3:53 pm |

        I’m beginning to suspect a sockpuppet. Who is Memphis sockpuppeting for?

        I’m the one proposing measures to reduce government. You’re the one who rejects measures to cut government power because he’s so afraid of government power.

        Burt Reynolds is not coming to save you.

      • Bart R | October 12, 2012 at 10:55 pm |

        I’m the one proposing measures to reduce government.

        No, you’re not. You’re just masquerading as one. You know as well as anyone that revenue-neutral will soon lapse into revenue-positive. It’s just a ruse to lull voters into trust. And even in the period before it collapses into revenue-positive, what government does this government inference “reduce” ? C’mon Bart, just be up-front about your loony-left motivation (hatred of corporations etc), stop trying to dress up as a friend of freedom.

        You’re the one who rejects measures to cut government power because he’s so afraid of government power.

        The only measures I recall rejecting here are your abovementioned attempts to expand government by phony revenue-neutral stealth tax.

      • johnfpittman | October 10, 2012 at 12:12 pm |

        So now you’re an expert on US laws? Where did you go to law school? What state bar were you called to? Because you’re sounding awfully confident in using words you appear unqualified to utter.

        Nationalization and privatization are opposites. Were I proposing nationalization, I might be proposing confiscation. However, I’m proposing privatization, so I’m advocating a reduction of confiscation.

        Pricing the carbon cycle isn’t confiscating oil. Indeed, there are many uses of oil that don’t incur carbon cycle costs: manufacture of plastics or fertilizer, pharmaceuticals and industrial chemicals are all profitable uses of petroleum resources utterly not affected by carbon cycle pricing. Further, those who own fossil fuel rights have never alienated the owners of the Commons — by definition of Commons — from shared rights in the carbon cycle. They can’t claim therefore that something’s being confiscated from them, any more than the owners of telephone lines can claim mobile bandwidth auctions confiscate their property. (Well, they can argue it, they did argue it, they went to court on it and were slapped down hard by judges at every level.)

        So you can stop displaying your ignorance in yet another field. Please.

      • I agree that I am not an expert on US laws, however, I do have training wrt to property and takings. I have read the Citizen’s Climate Lobby; it doesn’t have enough detail for me to comment except I note that even it recognizes that renewables need support because they are not economically efficient at this point.

        From a CEI write-up “The Supreme Court held in Armstrong v. United States that the Constitutional prohibition on uncompensated takings “was designed to bar government from forcing some people alone to bear public burdens which, in all fairness and justice, should be borne by the public as a whole.” Private individuals should not be forced to bear the costs of providing public goods desired by other people. Owning property should entitle the owner to the full use of that property, so long as the use of that property does not lead to the harming of other people or their properties. Ensuring compensation for regulatory takings will not only restore much-needed property protections, it also serves as the first step toward the development of a new generation of environmental protection.”

        You have stated a shared rights to the carbon cycle. Please, produce the legal decision where this was decided for the US. You appear to be treading on ground you are not an expert in.

        Otherwise, you are playing word games. You are proposing an unacknowledged right to the carbon cycle which you utilize carbon pricing that you are defining as privatization. I fail to see that a fee or tax, that is charged and then redistributed is anything other than just that a fee or tax redistributed.

        And point of fact, such use as production of fertilizers in most applications produce CO2, as do pharmaceuticals and industrial chemicals. Not all of them, but many to most depending on the process and the chemical. Many of these facilities have quite extensive treatment systems, and many are biodegradable, all of which adds to the CO2 buden. Perhaps your expertise here is questionable. Or is it that your version of pricing is neither neutralnor transparent? Politically it would be advisable to avoid making enemies of the farmers and pharmaceutical companies, so that is understandable, but not if the carbon cycle is a right. In which case, this looks a bit like Animal Farm, some animals are more equal than others.

    • One absolutely massive problem listening to the biologists etc who warn of CO2-driven misery : they are all state stooges (as are climate scientists), and the state has vested interest in promoting alarmism.

      Bart’s noble suggestion that dealing with CO2 (ignoring whether this is actually justified) will not expand the state command-and-control, is sadly just pie-in-the-sky; mainstream politicians will shoot it on sight.

      • BatedBreath | October 9, 2012 at 11:39 am |

        Pfft. Noble.

        I’m for diminishing the size and power of the state. To do that, you privatize more to take it out of government hands. With command-and-control power over access to CO2 emission out of the government hands and in the hands of its rightful owners — every citizen, per capita — the power of the government, of bureaucrats, the invitation to corrupt them, is erased. All lucrative users of CO2 emission, of the carbon cycle, must pay the going rate demanded by the Market, and not some bribe to civil servants. This is the logical outcome of the Policy implicatons of what Science has observed and conclusively proven about Climate Change.

        If you believe mainstream politicians will shoot it on sight, you may be right; but then you’d be recognizing the mainstream politicians as corporate communists, corrupt, or tyrants, and it would be time to call for the watering of the Tree of Liberty. Is that what you’re saying has come to pass in the USA?

  49. The policy is just a bureaucratic verbiage. A VERY small reduction in human CO2 emissions might be possible, but the atmospheric accumulation is obviously governed by climatic factors so it will not result in a measurable reduction in atmospheric CO2. It’s no bang for plenty of buck. Why? Profiteering?

    • pretty sure it’s governed by human activity

      • Edim | October 8, 2012 at 2:35 pm |

        You’re coming across as someone who acquired his understanding of policy, science and writing from comic book villains.

        http://www.hark.com/clips/wlvkgqdbcs-how-pathetic

        We see in you no evidence of foundation for your assertion of how much reduction in CO2 emission may be possible, and if you can construct a valid model for how climate factors determine CO2 levels then you’ve gone farther than all of science — an astounding feat worthy of a comic book supervillain indeed. How highly questionable are the ice core records, exactly? Be specific. Be precise. Demonstrate your ability to quantify your opinion.

      • Edim | October 8, 2012 at 3:41 pm |

        And how do you quantify Kernodle’s fingoist opinion?

        We’re looking for your ability, not someone else’s, as you’re the one making assertions.

        How much doubt exactly, in what terms and in what ways, applied to what scales and for what spans, do you percolate out of all Kernodle’s disparate disparagements of the ice core record?

        And how do you then propose this doubt be used in context of the fundamental principle of Science that we hold as accurate or very nearly true the proposition that by parsimony, simplicity and and universality best fits the data until new observations require amendment?

        I see nothing in Kernodle’s objections that amounts to an unsettling of ice core science.

      • Bart, I agree with that article, no need to add anything. Of course you see nothing in Kernodle’s objections that amounts to an unsettling of ice core science. That would dilute the message of the unprecedented CO2 levels, caused by humans. The doubt should be used to ask questions.

      • Edim | October 8, 2012 at 6:42 pm |

        Nothing whatsoever?

        Which demonstrates to us you have no credible ability to express any opinion on these issues.

      • No, it demonstrates my agreement with the article.

      • Edim | October 8, 2012 at 7:10 pm |

        While dodging every question that sheds some light on your own understanding or the quality of your assertions. Which makes you out to be dodgy, of the dodgy sort who makes assertions then dodges.

  50. Daniel Suggs

    I didn’t read through all the comments to see if anyone else suggested the same question, but mine is:
    What does it take to falsify AGW theory? (Is it even possible?)

    • The question is what will the consensus accept as falsified. I think they will accept nothing as long as they can claim that it’s still warming. So, it will have to be global cooling, they will have to accept that.

    • With all due respect, most would believe that the basic theory of AGW is not subject to being refuted. The question is what the impact of the human component will be in the actual system over timescales of importance to the human population.

      To make it clearer, some/many believe that the earth is in a long term cooling trend that will have short term fluctuations that will result in warming. They believe that the additional CO2 may result in a change or lessening of the long term cooling trend. Systemic trends regarding the climate are poorly understood by todays science, but that does not stop people from providing often incorrect answers

      • In proper science, everything is subject to being refuted. It may be very unlikely, but if the observations disagree, it’s refuted.

      • Not true. Observations could show that the net impact to the temperature is a slowing of the rate of temperature decline. Since we were unsure of the initial rate of decline, our observations could lead us to a wrong scientific conclusion.

      • I agree, but in time we will have more observations and sooner or later it may be completely refuted. At least the CO2-the-knob hypothesis will be refuted after some significant cooling in the next decade.

      • or confirmed?

      • The real system works on timescales inconsistant with humans desires for immediate answers.

      • Rob, I agree with that. Still, I think warmists have made their bed in such a way, it will be impossible to lay in it pretty soon.

      • Edim

        You may be right, but it is also possible that we are both wrong. Personally I keep looking at the data and the thing I like to watch pretty closely is the rate of sea level rise. If we see a sustained trend of over 7mm per year my position will change.

    • How do you falsify the theory that the Earth orbits the Sun? (is it even possible?)

      • David Springer

        That’s not a theory. It’s a fact. Or at least a fact if you change that to the earth and sun orbit their common center of gravity (which happens to be inside the sun). Theories explain facts. The acceleration of gravity on the earth is 32feet/sec/sec. That’s a fact. We have no theory of gravity. Facts are independent of theory.

        Got it? Write that down!

    • What does it take to falsify AGW theory? (Is it even possible?)

      While I agree that there is a basic scientific importance to asking that question, I will point out that I have been told many, many times that “most” “skeptics” not only don’t refute the basic physics of AGW, they also don’t doubt that ACO2 is, to some extent, warming the planet (they only question how much). Judith has stated that she doesn’t listen to anyone who doesn’t accept those basic premises of AGW theory.

      Yet I often hear “skeptics” say that a theory isn’t valid if it can’t be falsified, and that AGW as a theory is invalid in that it can’t be falsified.

      So then, the question strikes me: Why do most “skeptics” accept an invalid theory?

      • I don’t accept it.

      • Have you been assigned your under-the-bus seat yet?

        My point was to highlight the illogic of how some “skeptics.” In no particular order they:

        Say that “skeptics” aren’t monolithic.

        Treat “skeptical” viewpoints as if they are monolithic (by claiming that almost no “skeptics” believe as you do despite abundant evidence to the contrary on the very same blogs where they comment.

        Say that AGW theory (or hypothesis, whichever makes you happy) cannot be falsified.

        Say that theories or hypotheses that can’t be falfisifed aren’t valid.

        Say that they don’t doubt that AGW theory/hypothesis is valid – they only question the extent to which ACO2 is warming the Earth.

      • don’t forget some of them claim it HAS been falsified

      • don’t forget some of them claim it HAS been falsified

        Yes, of course. Those “skeptics” are also speaking from under Judith’s bus (David W. being just one of many examples), but they certainly are out there.

        They are not, however, part of the (self-proclaimed) larger group who simultaneously say that AGW can’t be falsified even as they say that valid theories/hypotheses must be falsifiable even as they say that they don’t doubt that that the basic AGW theory/hypothesis is valid (they only doubt the magnitude of the sensitivity and/or negative feedback).

      • David Springer

        There is no AGW theory. There is an AGW hypothesis.

        Got it? Write that down!

      • David,

        You might want to tell your friends at Heartland, and Roy Spencer, and The American Thinker, and Conservapedia to stop calling it a theory then…

        But no doubt they won’t listen to you as in fact it is a full-fledged theory and the bottom line is David, you are in fact the one is incorrect in this matter.

        The Theory of Anthropogenic Climate Change (which is far more robust than just “global warming”) is far beyond the hypothesis stage.
        For a well reasoned and well stated explanation as to why it has long since progressed from hypothesis to theory, those who are reasonable themselves can read it at:

        Calling something a theory doesn’t make it into one.

        If we google “Theory of Relativity” we get this for top hit:

        Farther down the list there is conservapedia, which you suddenly seem to respect since you cited it:

        http://conservapedia.com/Theory_of_relativity

        That’s a bona fide theory.

        Now google “theory of climate” and you get a hodge-podge of hits none of which are climate theories but which are in fact competing hypotheses of climate change.

        The word theory is abused enough by the unwashed masses. It’s inexcusable when those who know better do the same thing by promoting untested hypotheses like anthropogenic climate change into theories.

      • “There is an AGW hypothesis.”

        au contraire

        There is an AGW axiom.

        There, fixed it.

      • David L. Hagen

        Joshua
        Start by distinguishing between higher temperatures from higher CO2 (not as controversial – based on gas absorption/emission)
        versus the magnitude of amplification from water vapor feedback (very large range of values and highly controversial, depending on complex fluid dynamics etc.)
        The greatest uncertainty in models is with the impact of changes to clouds – where even the sign of the feedback is disputed.

        There is still a lot of physics to discover, model and validate. e.g., see:
        Counterintuitive, models wrong – rainfall more likely over drier soil

        But observations suggest otherwise: “We have analyzed data from different satellites measuring soil moisture and precipitation all over the globe, with a resolution of 50 to 100 kilometers. These data show that convective precipitation is more likely over drier soils”, says Wouter Dorigo.

        The new data contradicts established computer models. A conclusive explanation for this effect has yet to be found.

    • Hi Daniel. In the absence of changes to other climate forcings and assuming continued rise of CO2 AGW would be falsified by falling/static ocean heat content or falling/static global average temperature. Complications in assessing such are measurement issues, uncertainty re energy accumulation in the deep ocean, uncertain aerosol impact and natural variability masking the underlying trend. Currently the underlying trend is ~+0.16C/decade stable across the last three decades (Foster and Rahmstorf). Expect the same for the decade to come.

  51. If you for example show that the annual stellar parallax is not caused by the Earth’s orbit around the Sun, then it’s a start.

  52. The question should be: should government emphisis be on technological research or implementation? I’d say it should be research. I actually see evidence that there has been some success. While these two links are from Joe Romm’s propaganda site, they do help make the case:

    Suppose the IPCC of the day had actually gotten the science right and was predicting a global warming of 0.8 degrees C for the next century – a prediction that had already been supported by a number of years of physical data.

    Who here would have been agreed that this was going to be a good thing for the vast majority of future generations and who would have been forecasting doom and gloom and the end of civilization as we know it?

    Who would have invoked the “precautionary principle” in support of more government spending and advocated for deindustrialization of the West?

    • So if I sticking my hand in a pot of luke warm water won’t hurt, and sticking my hand in a pot of warm water won’t hurt, sticking my hand in a pot of boiling water won’t hurt either.

      IEEEEEE ….. OW …. OW…. DAMN… wooooo !

    • Political Junkie,

      You make an excellent point. No one would have advocated wasting money on trying the prevent that warming would give future generations and did actually give us.

      Your point makes it clear just how stupid we would be to damage the global economy when there is no persuasive evidence that the proposed policies would make a significant difference to the climate.
