We’re going to be hearing more about this – see press release here for example. I’ll add to this headnotes, but, for now, I’ll post up some URLs that some of you may find handy.
The underlying article by Hansen et al is at PNAS here. They thank Ralph Cicerone for his review comments. The article itself is a bizarre and undisciplined hodgepodge in which they discuss Hansen’s congressional testimony in 1988 for a while, an ocean sediment record in the Western Equatorial Pool, then sea levels and species extinctions, musing on Dangerous Anthropogenic Intervention and the Framework Convention – which Stephen Schneider set out as an objective some time ago. (Ross twigged to the increasing mentions of Dangerous Anthropogenic Interference – the trigger phrase for the Framework Convention – to which the U.S. is a party.)
