If you want to stay on top of the ins and outs of climate change PR hackery, you should be reading DeSmogBlog. The site, lead by the smart and insightful Kevin Grandia, stays on top of the often complex world of climate change science and politics while not being afraid to mix in a little activism. It's the force behind Coal-is-good.com and its mirror site, Coal-is-bad.com.
What pro blogger Brian Clark Howard thinks about DeSmogBlog: "DeSmogBlog is one of THE best places to go to online to find hard-hitting news and analysis on climate change, pollution and environmental policy. The site has a science and fact-based approach, but is written for the general public. They try to elucidate complex and often confusing issues while retaining an accessible and readable style. DeSmogBlog should be on the reading list of everyone who is concerned about the future of our planet."
