Surface melt water rushed along the surface of the Greenland Ice Sheet through a supra-glacial stream channel, southwest of Ilulissat. Polar ice sheets are now melting three times faster than in the 1990s, and that's added less than half an inch to already rising global sea levels, a new giant scientific study says. The acceleration of the melting, especially in Greenland, has ice scientists worried. (Ian Joughin/Associated Press)#
