Sometimes the Money Follows the Science, and Sometimes the Science Follows the Money . . .

The fervor favoring 'doing something' immediately about global warming has increased even as the scientific data supporting the primacy of manmade causes to that warming have decreased.

At least that's what this climatologist claims (hat tip Tim Blair).

I think this explanation/analysis says quite alot

And the political realm in turn fed money back into the scientific community. By the late 1990's, lots of jobs depended on the idea that carbon emissions caused global warming. Many of them were bureaucratic, but there were a lot of science jobs created too. I was on that gravy train, making a high wage in a science job that would not have existed if we didn't believe carbon emissions caused global warming. And so were lots of people around me; and there were international conferences full of such people. And we had political support, the ear of government, big budgets, and we felt fairly important and useful (well, I did anyway). It was great. We were working to save the planet!
