What have we learned from Climategate? Part II

by Judith Curry

The previous thread is getting unwieldly, there seems to still be much interest in discussing this, and there are some new interesting articles that I’ve spotted:

Principles of Reasoning. Part I: Abstraction

By Terry Oldberg

Introduction

In building climate models, climatologists generalize. Can the means by which they generalize be improved?

Yes they can. The means can be improved by replacement of intuitive rules of thumb called “heuristics” by the principles of reasoning.

What have we learned from Climategate?

by Judith Curry

On this one year anniversary of the unauthorized release of the emails from the Climate Research Unit at the University of East Anglia, there have been a number of articles reflecting on what the impact of this has been on both science and policy, and what we might have learned.

Michael’s controversial testimony: Part II

by Judith Curry

Here is further explanation why I think Michael’s testimony is significant, and why I think the issue of the attribution since 1950 will be the battleground in U.S. CO2 policy.  Michaell’s stated purpose for conducting this analysis was:

Pat Michael’s testimony has been generating significant controversy, both in the hearing and in the blogosphere.

Open thread: 11/15/10

Several people have asked  for a new open thread.  I hope that people can bring me up to date with what is going on elsewhere in the blogosphere, since I haven’t had time to check.   I will have time starting next Friday to engage more in the comments and get back to writing some technical threads.

What we know with confidence

by Judith Curry

Of the four IPCC assessment reports, I  think the first assessment report (FAR) presents the case with the greatest clarity.

Since the FAR was published 20 years ago, it is worth taking a look to see how their conclusions and levels of confidence and uncertainty have stood up to the test of time.

Uncertainty gets a seat at the “big table.” Part II

by Judith Curry

Some breaking news.  I received an email from the House of Representatives staffer who invited me to participate:

Just an FYI – Republicans will be inviting a witness for each panel.  This is a change from the usual practice of one witness per hearing, regardless of the number of panels.

Now this makes it much more interesting.  I have no idea who else has been asked.  Place your bets, make your recommendations!

The denizens of Climate Etc.

Climate Etc. has now attracted a critical (and growing) mass of “regulars.” I would like to try what Jeff Id did over at the Air Vent on his Reader Background thread. I will eventually provide a button for this thread on the top bar (next to blog rules), so it is easy to refer to (and add to).

Uncertainty gets a seat at the “big table”

On Nov 17, the U.S. House of Representative’s Committee on Science and Technology Subcommittee on Energy and Environment is holding a hearing on “Rational Discussion of Climate Change: the Science, the Evidence, the Response.”

The Scientific Method

by Mike Zajko

This post addresses an issue that has been coming up recurrently since the start of this blog. I hope it might be a way to step back and reflect on the nature of science in general, as well as a place where we can think about the methods applied in climate science more specifically. I’ve broken the following down into sections that can be read together or individually. I’m hoping for come good discussion of these and additional approaches to the scientific method.

Why engage with skeptics?

by Judith Curry

Many climate scientists have stopped engaging with skeptics, because they think it is either pointless or they don’t want to lend legitimacy to the skepticism. Those who think it is pointless seem mostly interested in protecting their time.  Those who view this as lending legitimacy to skeptics would seem to be acting in accord with IPCC/UNFCCC ideology.

No ideologues: Part III

by Judith Curry

Some very constructive dialogue on the previous two threads.  The use of the word “heretic” in the Scientific American article just begged for the word “dogma” to be used.  Given its range of connotations, it seems that dogma or even dogmatism doesn’t really convey what I am intending to for many people.

No dogma(tism): Part II

by Judith Curry

The dogma post seems to have a struck a nerve, but both sides seem be talking past each other.  One side sees the dogma as self-evident, the other side wants evidence.

Ending the war with skeptics

by Judith Curry

As we approach the anniversary of Climategate, I am getting a lot of queries from reporters, which invariably includes the following question:

Is there any hope for ending the war between climate scientists that support the IPCC and skeptics?

My answer is “yes.”

No dogma

by Judith Curry

My posts on positive feedback loops (here and here) have engendered some interesting discussions, particularly at Collide-a-scape and Die Klimazweibel.  While many are pondering the points I raise, most of the “insiders” don’t like the idea of “IPCC dogma.”

Reversing the direction of the positive feedback loop: Part II

by Judith Curry

I can’t predict in advance when a thread will generate a lot of activity; I’m learning that anything with “climategate” in it is likely to have a lot of traffic.  Since the first thread  has almost 500 comments, I would like to address some of the questions and issues raised, and redirect the discussion.

I’m at Purdue University, preparing for a panel discussion with Andy Revkin and Roger Pielke Jr. on “Beyond Climategate.”  The following three questions have been posed:

Decision making under climate uncertainty: Part I

by Judith Curry

Based upon the precautionary principle, the United Nations Convention on Climate Change (UNFCCC) established a qualitative climate goal for the long term: stabilization of the concentrations of greenhouse gasses in the atmosphere. The view of climate change held by the UNFCCC regards both the problem and solution as irreducibly global. This view of the problem has framed the IPCC’s assessment and national funding priorities on the subject of climate science.

Extended peer community

by Judith Curry

Michael Lowe posted this comment on the Disagreement  thread:

Wouldn’t it be great if more science was like this – hundreds of interested bloggers, laypeople and scientist interracting, arguing, disagreeing, learning. Maybe this is the real postnormal science!

Uncertainty and the IPCC AR5

by  Judith Curry

I am starting to see some encouraging signs that people (including the IPCC) are paying more attention to the uncertainty issue as it relates to climate change.  Nature has an editorial on this issue that summarizes the situation as:
