^These guys stay on top of climate change issues and news with a focus on debunking the AstroTurf campaigns of the oil companies. It is a treasure trove of information. Jim's Manifesto is the mission statement of the site and I think it is worth a read. FTA:
Conspiracy theorists will be happy to hear that I'm not suggesting that Frank Luntz (a consultant to the republican party) or even a dubious cabal of ethics-free PR people are solely to blame for the public confusion on climate change. They have received extensive, if clumsy assistance from the media, which in a lazy and facile attempt to provide "balance" is willing to give any opinion equal time as long as it is firmly in contradiction with another.
