See Climate Change Reconsidered at http://www.nipccreport.org/aboutReport.html
for 880 pages of overwhelming science, evidence, and scholarship showing that the UN’s IPCC’s predictions of catastrophic AGW are utterly lacking in convincing scientific evidence.

Using the words of Al Gore, I’d say that “the debate is over”----there is no convincing scientific evidence that the human release of CO2 (and methane etc.) is causing or will cause catastrophic heating of the Earth’s climate.

Nevertheless, I suspect that it will be years b/f most of the true believers let go of their faith in AGW.
