All of you climate-media followers have probably already seen pre-coverage of the IPCC Working Group III Summary for Policymakers (SPM) which is due out this Friday. Recall that WGIII addresses mitigation: how to actually do something about greenhouse gas emissions.
The SPM's are just summaries. The full reports are starting to come on line. Thanks to RealClimate who pointed out that the full WGI report, about the science, is now online.
