Joe Romm is a pretty credible and well informed guy, a Phd physicist himself, with more "inside the beltway" experience than Jim Hansen (whom I greatly admire).
Romm feels that Hansen is missing the strong point of the ACES package, and way too negative on the shortcomings.
Much as I am happy to devote many Climate Progress posts to publicizing Hansen’s leading edge climate science analysis (see links below), I am unhappy to have to waste any time at all debunking his bleeding edge climate policy analysis ....
Still, his arguments need debunking because he is mostly recycling myths that others are pushing — and with the country’s top climate scientist putting his name on this collection of false and misleading statements, they will no doubt be parroted by yet more people. Hansen has just written, “G-8 Failure Reflects U.S. Failure on Climate Change” for The Huffington Post.
