UN Scientist refuses Nobel Prize on Global Warming

Interesting. [Link]

A United Nations scientist has refused the Nobel prize that he (as part of the IPCC) is supposed to share with Al Gore, and for the most damning possible reason.

The scientist (IPCC member John R. Christy) claims that the prize was based on a misunderstanding of science:

Has the global warming alarmism movement hit its apex? Maybe so. In recent weeks, we've seen a resurgence of hard scientists who have come out strongly against the warm-mongers, the latest of which is Intergovernmental Panel on Climate Change member John R. Christy who in an editorial in today's Wall Street Journal tells the world that not only does he not believe no one's proven humans cause global warming, he's refusing his "share" of the Nobel Peace Prize that he was awarded because it was based on a misunderstanding of science.

Is it now heresy to speak out against global warming? When did skepticism in science go out of vogue?
