Arctic sea ice is refreezing quite slowly. Go figure!
When records were being set for loss of summer Arctic sea ice area (2007) and sea ice volume (2008), the deniers spent all their time talking about how quickly the ice refroze in the ensuing months. Now, they are strangely quiet on the remarkably slow refreezing we’re seeing. Why the slow refreezing this year? I’ll […]

Nature: “Dynamic thinning of Greenland and Antarctic ice-sheet"
The most detailed satellite information available shows that ice sheets in Greenland and western Antarctica are shrinking faster than scientists thought and in some places are already in runaway melt mode, a new study found…. Using 50 million laser readings from a NASA satellite, scientists for the first time calculated changes in the height of […]

(Thanks to Real Climate and Climate Progress for the shout-outs.) Send links to these videos to that irritating troll on your blog, or your nice-but-clueless-about-climate neighbor who needs some good […]

The Climate Post: Grid, for lack of a better word, is good
First Things First: Cars, trucks, planes, and other things that go add more greenhouse gas to the atmosphere than any other sector where end-users burn their own fuel. And transportation added more energy-and-climate headlines this week than any other sector, driven by an emergency congressional payout to continue the “cash-for-clunkers” program and General Motors’ promotional […]

Will we see record low Arctic ice volume this year?
“Daily sea ice extent as of July 21. The solid blue line indicates 2009 … the purple line shows 2008; and the solid gray line indicates average extent from 1979 to 2000.” The blogosphere and scientific community are all abuzz as to whether 2009 will beat 2007 in minimum Arctic sea ice area. See, for […]

New NSIDC director on “death spiral” Arctic ice
I interviewed by email Dr. Mark Serreze, recently named director of The National Snow and Ice Data Center. Partly I wanted him to explain his “death spiral” metaphor for Arctic ice (see NSIDC: Arctic melt passes the point of no return, “We hate to say we told you so, but we did”). And partly I […]
