"The Petition Project", a petition to NOT sign on to the Kyoto accords because anthropogenic global warming was far from proven, and signed by over 30,000 scientists (disproving consensus) has been scrubbed from the web, even the Wayback Machine.
Snopes says there is no proof that the scientists who signed were, in fact, scientists, but I know I had to provide my bona fides before my signature was accepted. Linus Pauling was a signatory, too. Snopes is full of sh*t.
