In case you missed it, there's a new paper by James Hansen and lots of other people which is generating quite a bit of interest. It's not been reviewed - it's in the "for discussion" category at EGU's inter-active open access journal Atmospheric Chemistry and Physics. That is, it's not had the final peer review. (See comment from Xavier Onassis below.) That's an interesting model for scientific publication in itself. There are not many journals that do this.
I haven't read the paper yet, and even if I had, the paper is quite long at 32 pages not including references and figures (61 pages in total). My articles are long enough as it is. Plus I'd like to wait and see what comments it attracts in the journal itself. Maybe over time I'll write about some aspects of it as shorter articles, rather than attempting to give a view of the whole. From what I've heard, it's a paper that will challenge people - scientists and policy makers and the general public, with lots of food for thought.
However don't let me stop you from commenting. It hasn't stopped Anthony Watts from posting lots and lots and lots of photos of New York and writing stuff like "it's not under water yet so it never will be - so there". (Anthony is a sea level rise denier from way back. It's a pet denial of his.)
Chris Mooney wrote something about the paper, if you want an introduction. He's got some reaction from a few scientists.
Update: here's Jim Hansen himself:
I snagged the video from Peter Sinclair at ClimateCrocks, which has a transcript too. He's a couple of other videos here and here, which are about Hilary Clinton's strong renewable targets, just announced.
