Check out that last paragraph--journalist Andy Revkin seems to be continuing his painfully slow journey towards climate realism

Fun With CO2 in Greenland - Dot Earth Blog - NYTimes.com

Francesca Galeazzi is a self-described “nasty, evil woman” in this short video clip, shot in Greenland several days ago and aimed at pillorying so-called “carbon offsets” as a dubious justification for actions that release a lot of carbon dioxide, the main heat-trapping emission building in the atmosphere. At the edge of the retreating Jacobshavn Glacier, she opens a valve on a cylinder holding about 13 pounds of CO2 and the greenhouse gas whooshes out with a long hiss.

P.S. There was an interesting study in Nature Geoscience last Sunday showing pretty clearly that the accelerating flow of the Jacobshavn glacier in recent years was most likely driven by an influx of warm deep seawater, and that shift was likely due to changes in pressure and wind patterns over the North Atlantic Ocean. There are few straight lines in the Arctic climate puzzle, and particularly the Greenland piece of that puzzle, as I’ve been writing for a while now. More evidence that, while the basics remain clear, the details that matter most to people (rate of sea rise) are laden with complexity that must be acknowledged.
