Reversing the direction of the positive feedback loop: Part II

Climate scientist Judith Curry is a brave woman. On 4 Nov Judith was at Purdue University, preparing for a panel discussion with Andy Revkin and Roger Pielke Jr. on “Beyond Climategate.” She posted a preview of her talk, focusing on “The positive feedback loop” – excerpt:

(…) I think the dynamics are much more complicated, and can only be understood by considering the ever vexatious feedback loop. There has been a particularly toxic positive feedback loop between climate science and policy and politics, whose direction has arguably been reversed as result of Climategate.

The scientists provided the initial impulse for this feedback loop back in the 1970’s and 1980’s. The enviro advocacy groups quickly saw the possibilities and ran with it, with the scientists’ blessing. The enviro advocacy groups saw the climate change issue as an opportunity to enlist scientific support for their preferred energy policy solution. Libertarian think tanks, the traditional foes of the enviro advocacy groups, began countering with doubts about the science. International efforts to deal with the climate change problem were launched in 1992 with the UNFCCC treaty.

That post generated a comment-storm, so Judith has posted a Part II with a more in depth discussion of her framing:

(…) The previous post was written for the Purdue event, I had 10-15 minutes to make a statement. I put forth an argument (the feedback loop) with premises. To many, the premises I put forth seem self evident. Others are demanding “proof” and “evidence” of my premises. My argument, and the premises that it is based on, are offered up for discussion on this blog.

Are any of you tired of the endless debate over who is hero and who is villain in the scenario unfolded in the CRU emails? Even if we were to get rid of all of the “objectionable” characters on both sides of this, would climate science be fixed? Would we have sensible energy policies? No and no. And we can’t frame/narrate/communicate our way out of this either. The problems and the issues are much bigger: geopolitics, economics, clashes of values. An extremely wicked problem for which science does not provide a solution.

(…)

So far Judith has about 500 comments on Part I, and as I write 378 comments on Part II.
