a history of anti-consensus voice-aggregation against "global warming" and Kyoto

From Lawrence Solomon in Financial Post (hat tip: Randy Baker)...

Solomon opens with the question: "How many scientists does it take to establish that a consensus does not exist on global warming?"

He then provides a list of efforts to establish that "consensus" does not exist on this question.

-in 1992, 47 scientists signed a “Statement by Atmospheric Scientists on Greenhouse Warming” which trashed “the unsupported assumption that catastrophic global warming follows from the burning of fossil fuels and requires immediate action”

-later that year, the Heidelberg Appeal resulted in 425 scientists and other intellectual leaders signing the appeal; over the years, this number grew to 4,000 signatories, including 72 Nobel Prize winners

-the Leipzig Declaration on Global Climate Change: 150-plus signatories

-the Cornwall Declaration on Environmental Stewardship in 2000: 1,500-plus clergy, theologians, religious leaders, scientists, academics and policy experts (including me!) who were "concerned about the harm that Kyoto could inflict on the world’s poor"

-the Oregon Institute of Science and Medicine’s Petition Project in 2001: 17,800 signatures-- made...

more astounding because of the unequivocal stance that these scientists took: Not only did they dispute that there was convincing evidence of harm from carbon dioxide emissions, they asserted that Kyoto itself would harm the global environment because “increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.”

The group renewed their effort last year and now have 31,000 signatures, 9,000 of them with PhDs.
