Six Degrees videos - Six degrees 03 February 08

Great!! I think they could have included in the 6 degree scenario the possibility of hydrogen sulfide gassing, with reference to what they think might have happened during the end-Permian. I did see that in another docu about past mass extinctions. They could have perhaps gotten some footage from that film to include in this one.

Anyway, let’s hope this inspires people to take this problem seriously and start reducing GHGs (& vote for the right candidates). The idea about tipping points came across, but mainly as an albedo issue. I can’t remember if there was anything in there about melting clathrates and permafrost (I was also cooking at the time).
