Greenland is melting. NASA scientists say they are astonished at how fast its ice sheet is thawing.

Said a flabbergasted Son Nghiem of NASA's Jet Propulsion Laboratory: “This was so extraordinary that at first I questioned the result: Was this real or was it due to a data error?" Researchers say global warming is largely to blame; warmer ocean waters are eating away at the ice.
