How much do you really know about global warming?

Most likely you've already read (at least) a couple of news articles and seen a few TV shows tackling the subject of climate change. Probably you've even watched Al Gore's movie. But how much do you really know about global warming?
Information tends to be buried deep in scientific papers that usually address only narrow topics, and news articles are often unreliable or imprecise. Fortunately, a valuable resource has just been made available by the IPCC (Intergovernamental Panel on Climate Change). After 6 years of work, and involving more than 2500 expert scientific reviewers, 800 contributing authors and 450 lead authors from 130+ countries, the panel is publishing its "Climate Change 2007" assessment report, which focuses on three main areas: 1) the basics, 2) the impacts and 3) the mitigation possibilities.
Here are the links for the documents available for download at this moment:

• Part I: "The Physical Science Basis" [summary] [full report]
• Part II: "Impacts, Adaptation and Vulnerability" [summary]
• Part III: "Mitigation of Climate Change" [summary]

No registration is necessary and all the documents can be downloaded completely free of charge. The final version of the IPCC Climate Change 2007 report is currently being distributed to all the member countries, who have already reviewed, agreed to and approved its content. This report is simply a must-have for anyone who would like to get all the facts about global warming!
