“Somebody cited Margaret Thatcher, a lady of whom I am always happy to call myself a fan. In her book “Statecraft”, in a chapter called “Hot Air and Global Warming”, she actually repudiated much of what she had written when she pointed out that people were getting quite hysterical about this. I think she was absolutely right and I urge the Secretary of State to be very cautious when she gets to Paris, and to remember that there is a difference between healthy scepticism and denial.”
Nice.

Digging in the Clay 
Impressively, Michael Crichton had also figured out the game in 2002, and he dismantled the idea of global warming alarm in his book State of Fear.
Michael Crichton had two principle concerns concerning science and society, which led to his criticism of global warming. First, he warned against governments capturing science as a tool to cow the population into funding and submitting to politicians’ policies. Second, he thought scientists in many fields were far too certain and trusting of their knowledge and tools, especially computerized systems.
Judging by what others have said on blogs, I was not the only one for whom his book (State of Fear) triggered a skeptical stance toward global warming alarm. It was a wake up call for some, and for others, like myself, it was an inoculation against the viral media onslaught to come.

Have you read R.V. Jones’s “Reflections on Intelligence”?
Seems to me that quite a few of his observations have bearing on how we got lumbered with CAGW.
In today’s Telegraph there’s an interesting article on possible changes to energy and environmental policy now that the Tories are not tied to the Lib Dems. The Matt cartoon is also well worth the effort of looking it up. http://www.telegraph.co.uk/news/matt/
