Massive retreat of Greenland glacier happens overnight.
The north branch of Greenland’s Jakobshavn glacier retreated one mile from July 6 to July 7, new NASA photos show.
“The calving front – where the ice sheet meets the ocean – retreated nearly 1.5 kilometers (a mile) in one day and is now further inland than at any time previously observed.”
The massive retreat occurred after a 2.7 square mile area of ice broke up overnight. To put that in perspective, that is an area of ice more than twice the size of New York’s Central Park.
