Time to Start Walking

From Robert Lee Hotz's Jan 2 column in the Wall Street Journal, "The Warming Earth Blows Hot, Dry, and Chaotic":

Alaska's low-lying ice fields are disappearing at two to three times the rate of a decade ago, according to aerial surveys by researchers at the University of Alaska. Since 2000, Greenland alone has lost 355.4 square miles of ice -- an area 10 times the size of Manhattan -- Ohio State University researchers reported. Using data from two NASA satellites, they determined that Greenland's 32 largest glaciers lost three times as much ice last year as the year before.

"I wouldn't run for the hills," says glacier analyst Eric Rignot at NASA's Jet Propulsion Laboratory. "But it might be time to start walking."
