Melting on the Greenland Ice Cap: Image of the Day

Dangling below the Arctic Circle, the ice sheet on Greenland is a vestige of the last ice age. Other ice sheets at its latitude have long since dwindled away, but the Greenland Ice Sheet persists, preserved largely because of its own tremendous size. But change is creeping over the ice sheet: earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17158 glaciers on its edges are sliding into the Atlantic at an accelerating rate and earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17607 pools of water puddle on the surface of the ice as the summer melt lengthens. Piece by piece, evidence has accumulated to show that the ice sheet is shrinking.
