The Climate Wars, prequel......
An article in the Nude Scientist (Ms. Rabett buys it for the centerfold) sets the stage for the AR4 climate wars:

KEVIN TRENBERTH reckons he is a marked man. He has argued that last year's devastating Atlantic hurricane season, which spawned hurricane Katrina, was linked to global warming. For the many politicians and minority of scientists who insist there is no evidence for any such link, Trenberth's views are unacceptable and some have called for him step down from an international panel studying climate change. "The attacks on me are clearly designed to get me fired or to resign," says Trenberth.The attacks fit a familiar pattern. Sceptics have also set their sights on scientists who have spoken out about the accelerating meltdown of the ice sheets in Greenland and Antarctica and the thawing of the planet's permafrost.
An issue on which we have had a few dozen chosen words.
Another sensitive area is the concern that existing models of ice sheets on Greenland and Antarctica massively underestimate future melting and consequent sea-level rise. "Our understanding of the dynamics of ice-sheet destruction has completely changed in the last five years," says Richard Alley of Penn State University, a lead author of the chapter on ice sheets who expects to find himself in the firing line over this issue. "We used to think it would take 10,000 years for melting to penetrate to the bottom of the ice sheet. But now we know it can take just 10 seconds," he says.
The rethink has come from the discovery that when surface water from melting ice drains down though crevasses it can lubricate the join between ice and bedrock. This mechanism appears to explain the faster discharge of ice from Greenland into the Atlantic, but it has yet to be incorporated into ice-sheet models, which still assume that the limiting factor is the rate at which heat penetrates through solid ice.
