Steve Hayward’s post below on believer-turned-skeptic David Evans, a former climate modeler for Australian govt., is worth dwelling on.

Evans’ remarkable confession reveals how an uncertain scientific field is being manipulated by politics and government grants:

The evidence was good enough: not conclusive, but why wait until we are absolutely certain when we apparently need to act now? So the idea that carbon emissions were causing global warming passed from the scientific community into the political realm, and actions started to happen. . . . 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 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! But starting in about 2000, the evidence. . . fell away or reversed.

Damning stuff. And on such fragile science Greens want to fundamentally change western civilization?
