Encouraging admission of lower climate sensitivity by a ‘hockey team’ scientist

WUWT
"Andrew Revkin published the email today at the NYT Dot Earth blog as a comment in that thread, so now I am free to reproduce it here where I was not last night. Below is the comment left by Andy, quoting Annan’s email, bolding added:
The climate scientist James Annan sent these thoughts by email:
Well, the press release is a bit strange, because it sounds like it is talking about the Aldrin et al paper which was published some time ago, to no great fanfare. I don’t know if they have a further update to that.
Anyway, there have now been several recent papers showing much the same – numerous factors including: the increase in positive forcing (CO2 and the recent work on black carbon), decrease in estimated negative forcing (aerosols), combined with the stubborn refusal of the planet to warm as had been predicted over the last decade, all makes a high climate sensitivity increasingly untenable. A value (slightly) under 2 is certainly looking a whole lot more plausible than anything above 4.5.


And this is what many have been saying now, that the climate sensitivity has been overestimated. Kudos to Annan for realizing the likelihood of a lower climate sensitivity.
