The people at RealClimate have saved us all a great deal of work by putting together a one-stop post for climate change information.

The article highlights key information for novices and experts alike, and also provides links for debunking the bogus arguments of skeptics. To their list, I would add the following two resources:

1. DeSmogBlog's Denier Database: offers a thorough and ongoing investigation of the 61 signatories to an anti-climate-change petition sent in April, '06 to Canada's Prime Minister. Supporters claim it is signed by "60 leading scientists." DeSmogBlog reports on their credentials and their connections (or their lack of connections) to the oil or tobacco industries.

2. SourceWatch: This is my first stop whenever a new anti-global warming claim hits the press. SourceWatch is a wiki environment documenting the PR and propaganda activities of public relations firms and public relations professionals engaged in managing and manipulating public perception, opinion and policy. It also includes profiles on think tanks, industry-funded organizations and industry-friendly experts that work to influence public opinion and public policy on behalf of corporations, governments and special interests.

As any reasoning person knows, understanding who is making a specific claim can be as important as the claim itself. DeSmogBlog and SourceWatch provide two excellent sources for the background of key deniers, and for discovering who writes their pay cheques. RealClimate is THE blog for global warming science.

Happy debating!
