Climate Coup — The Politics

How the regulating class is using bogus claims

about climate change to entrench and extend their

economic privileges and political control.

The Science

The sister article Climate Coup—The Science (a more mainstream version of The Skeptic’s Case) contains the science foundation for this essay. It checks the track record of the climate models against our best and latest data, from impeccable sources. It details how you can download this data yourself. It finds that the climate models got all their major predictions wrong:

Test Climate Models Air temperatures from 1988 Actual rise was less than the rise predicted for drastic cuts in CO2 Air temperatures from 1990 Over-estimated trend rise Ocean temperatures from 2003 Over-estimated trend rise greatly Atmospheric hotspot Completely missing –> water vapor feedback not amplifying Outgoing radiation Opposite to reality –> water vapor feedback not amplifying


The latter two items are especially pertinent, because they show that the crucial amplification by water vapor feedback [i] assumed by the models does not exist in reality. Modelers guessed that of the forces on [...]

Survey shows skeptics are smarter

I kid you not. Chris Mooney at Desmog has got the data that shows skeptics were more literate and numerate than believers, and he wants to share it.

Last week, an intriguing study emerged from Dan Kahan and his colleagues at Yale and elsewhere–finding that knowing more about science, and being better at mathematical reasoning, was related to more climate science skepticism and denial–rather than less.

When faced with the news that smarter more mathematical people were skeptical of man-made global warming, it’s a sure bet that as a Desmogger, he would fail to reach the obvious conclusion.  Are believers gullible fools who can’t see the flaws in the reasoning? No. Skeptics are more literate and numerate about everything else, except for climate science, when they become dangerously overconfident and seek only to use their intellect to punch holes in the theory. Its not like these bright types have anything else to do is it? Of course.

This is bad, bad news for anyone who thinks that better math and science education will help us solve our problems on climate change. But it’s also something else. To me, it provides a kind of uber-explanation for climate skeptic and denier behavior [...]
