And (via James again, I think) I ran across Tung and Camp on climate sensitivity, and Knutti et al.. They too think its 3 oC (well 2.8 +/- 0.9; and about…
Interesting post on this over at James Empty Blog. So: Weitzmans basic thesis is: the PDF of the climate sensitivity has a long fat tail; the cost diminishes less quickly; so the "expected utility", which is the integral of the two, is divergent. This has echoes of mt's arguments, which he has been…
I find that I need to understand the "defining dangerous climate change stuff". Up to now I've rather dismissed it as someone else's problem but now I need to know more. This is not a very satisfactory post, in part because I ran out of time to finish it. Its more a request for feedback, possibly…
When I was a wee mustelid, I wrote about this; and there is an RC piece, and as far as I know, its all still valid.
But this post is aimed at those who put an "s" into poles in "What exactly is the mechanism that causes the poles to warm faster than the tropics as a result of climate change?" when…
