"The amount of ice lost by Greenland over the last year is the equivalent of two times all the ice in the Alps, or a layer of water more than one-half mile (800 meters) deep covering Washington DC," said Konrad Steffen of the University of Colorado at Boulder.
Using data from military and weather satellites to see where the ice is melting, Steffen and his colleagues were able to monitor the rapid thinning and acceleration of ice as it moved into the ocean at the edge of the big arctic island.
The extent of the melt area was 10 percent greater than the last record year, 2005, the scientists found.

Greenland Ice Sheet Melting at Record Rate
