A 4 degree world

A recent conference in Oxford attended by the best and brightest of the climate science academy examined the prospects and impacts of 4 degrees of global warming. The prognosis is not good. New Scientist have done a good summary with a Google Earth interactive guide (download .kmz file), but if you have a spare hour listen to some of the presentations available on the conference website; Prof. Schellenhuber's and Richard Betts' from the Met Office are a must.
