in West Antarctica's Amundsen Sea Sector are thinning twice as fast near the coast as they did in the 1990s, researchers report. According to study results detailed in the current issue of Science, aircraft and satellite surveys of the ice sheet indicate that the glaciers are losing 60 percent more ice to the sea than they gain from snowfall. Ice loss at this rate could raise sea level by more than 0.2 millimeter a year--as much as the previously estimated contribution from all of Antarctica.
