Given our increasingly slim chances of avoiding more than 2˚C of global warming, it makes sense to start thinking about what a world hotter than that could be like.
The University of Oxford recently hosted a conference on the subject: 4degrees International Climate Change Conference: Implications of a Global Climate Change of 4 plus Degrees for People, Ecosystems, and Earth Systems.
32 of the short lectures are available free, via iTunes.
As an aside, posts might be thin here for the next while. Work is busy, and I am concentrating efforts on BuryCoal. If you haven’t had a look at that site yet, please do. Some good discussions on the posts people have already written would be just the thing.
