Climate boomerangs

by Judith Curry

A boomerang effect occurs when a message is strategically constructed with a specific intent but produces a result that is the opposite of that intent.

Both sides of the political debate surrounding climate change in the U.S. seem to be feeling the boomerang effect.

Can we make good decisions under ignorance?

by Judith Curry

Does decision making require high levels of confidence? Can there be such a thing as making good decisions under deep uncertainty and even ignorance?   What decision making criteria or guidelines make sense under these circumstances? How does overconfidence hamper the decision making process?

A modest proposal for reforestation

by Judith Curry

Douglas Sheil from Uganda sent me an interesting article with the provocative title “A modest proposal for wealthy countries to reforest their land for the common good.”  Following in Swift’s footsteps, the paper uses satire to highlight some inconsistencies regarding international agreements on land cover and ecosystem conservation.

On e-salons and blogospheric argumentation

by Judith Curry

On a previous thread, I made the following statement:

I am striving for something different, sort of an e-salon where we discuss interesting topics at the knowledge frontier.

Lets take a closer look at how this might work.

Slaying the Greenhouse Dragon. Part IV

by Vaughan Pratt

While I seriously doubt whether climate skeptics will thank me for pointing it out, I don’t believe their arguments impress the swing voters in the climate debate as convincingly as they might.  With this in mind I’d like to propose a strengthening of the skeptic argument that downward longwave radiation or DLR, popularly called back radiation, cannot be held responsible for warming the surface of the Earth.

Meta-expertise

by Judith Curry

How can we cope with becoming more hyper-specialized and fragmented in our personal knowledge bases while at the same time being exposed to too much relevant formation on the internet for any of us to learn and process?

Michael Smithson provides a modest proposal for addressing this challenge: We should all become expert about experts and expertise. That is, we should develop meta-expertise.

Two (+1) new uncertainty papers

by Judith Curry

My paper “Reasoning about climate uncertainty” has now been published online at Climatic Change; it looks like mine is the first to make it online of the papers in the special issue entitled Framing and Communicating Uncertainty and Confidence Judgments by the IPCC.

Also of relevance, there is a new working paper from the LSE Grantham Research Institute entitled “Scientific uncertainty: a user’s guide” (h/t Bishop Hill).

Representative Concentration Pathways

by Judith Curry

“Representative concentration pathways” is the new phrase for what the IPCC used to refer to as “emissions scenarios.”  Lets take a look at the new RCP’s being used for the AR5.

Bardian insights

by Judith Curry

Shakespeare’s writings are infused with with weather references, and even some that are arguably relevant to climate change.  The insights, however, come from the academic debate surrounding the actual authorship of the Shakespearean opus.

Arctic Imperative

by Judith Curry

In my congressional testimony, I discussed the idea of climate change winners and losers.   In the Arctic, where climate is changing most rapidly, will there be winners or losers?

Carbon cycle questions: Part II

While I have culled considerably the previous thread, it is getting unwieldy for those of you that want to carry on extensive technical discussions.  So here is another thread for extended technical discussion.  Keep your more general comments on the previous thread.  Thank you.

Carbon cycle questions

by Judith Curry

I just finished listening to Murry Salby’s podcast on Climate Change and Carbon.  Wow.

On the attribution of flood peaks

by Judith Curry

The hypothesized link between a warming climate and increased frequency and magnitude of floods goes something like this:  a warmer climate is associated with more water vapor in the atmosphere, which means more rainfall and more floods.  Is there any observational support for this link?

Trying to put the Climategate genie back in the bottle

by Judith Curry

The viral “Climategate” has had a substantial impact on public perception of climate science and scientists.  Several strategies have been tried to put the Climategate genie back in the bottle, without much success.  An article by Peter Wood published in the Chronicle of Higher Education entitled “Climate Thuggery” describes one such strategy, which I don’t think is working too well.

Going viral

by Judith Curry

Climategate – where did this almost perfectly strategic — yet deeply unfortunate — catchphrase come from? Was the term the genius of a conservative think tank and industry-backed strategy or does evidence support an alternative explanation?

Climate pragmatism

by Judith Curry

[P]ublic support for the environment is at more than 30 year-low, cap and trade is dead, perhaps for good, and global warming has become as partisan and polarizing an issue as abortion and gun control.

Climate Pragmatism offers a framework for renewed American leadership on climate change that’s effectiveness, paradoxically, does not depend on any agreement about climate science or the risks posed by uncontrolled greenhouse gases.
