A crisp and crunchy show this week, as Gareth and Glenn interview Dr James Renwick about the  IPCC's cautious new report on extreme weather and the riskier future we all face. With added ruminations on the potential slowdown in international action at the Durban conference, record greenhouse gas levels reached in 2010, the prospect of "hyper warming" and the release of some lightly warmed over stolen emails. No debunking a la Cook this week, but he'll be back soon, and we have news of the world's first hybrid jet aircraft.
