So, in his last paper in the Proceedings of the National Academy of Sciences,
Mr. Hansen and Makiko Sato wrote,....

For those posters/lurkers who were smart enough to not get a degree in the physical sciences...
"Proceedings" (also known under the acronym of PNAS) is just about as good as
it gets in terms of peer-reviewed journals of science.
I've helped review/edit a number of papers for review/publication by PNAS and
the standards are STRINGENT.

(Yep, some junk does get by the reviewers now and then...but it's a low percentage deal.)

Yes, and for that reason it might do some of those reading this thread (though I am a bit late in posting this) to read the actual paper, in PDF document form: Trends of measured climate forcing agents

I recommend reading the paragraph entitled "Carbon Dioxide" on the last page, which Michaels alludes to, in which Dr. Hansen indicates that CO₂ emissions must eventually be curtailed or sequestered, "to stabilize atmospheric composition". His reasoning is that the warming which is currently occurring (with which Michaels agrees, contrary to the more vocal global-warming skeptics who claim there is no warming at all), while not likely to cause catastrophic warming, is still capable of causing significant climate change.

Hansen knows what he's doing, and I agree with what he writes. Global-warming skeptics should also, particularly now that Pat Michaels and he agree on the next-century prediction.

Note also that Hansen is predicting, if the current rate of warming continues for the entire next century, an Earth as warm as the mid-Pliocene, 2 deg C warmer than present, with sea levels 25 meters higher than today. Interesting that Michaels didn't mention those numbers in his piece, isn't it?
