Says the FT, via DSB. Since I’ve already argued that Stern is over-bleak, Im surprised he has got more pessimistic. Whats up?
Apparently “We underestimated the risks . . . we underestimated the damage associated with the temperature increases . . . and we underestimated the probabilities of temperature increases…. Stern said data published since the report came out had led him to change his mind.
Aha! Interesting. What is this new data?
He highlighted the publication last year of the most comprehensive study yet undertaken of climate change science. Conducted by the Intergovernmental Panel on Climate Change, a body of the world’s leading climate scientists convened by the United Nations, it predicted a temperature rise of 3°C within the next 100 years.
Well, no, it didn’t; but you’re not going tooo far wrong reading it to say that. However, all that was available from the TAR. The AR4 didn’t really revise any TAR projections. So Sterns assertion that new data has caused him to revise his opinions would seem to be nonsense.
Catastrophic consequences for the planet were predicted unless greenhouse gas emissions were stabilised and then cut within the next decade.
And now we’re off in la-la land. Who appointed this man to do a serious review? Though to be fair to Stern (must I be?) those may be the FTs words rather than his, its hard to be sure.
