Arctic river ice deposits rapidly disappearing
18 April 2017
WASHINGTON, DC — Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.
River icings form when Arctic groundwater reaches the surface and solidifies on top of frozen rivers. They grow throughout the winter until river valleys are choked with ice. Some river icings have grown to more than 10 square kilometers (4 square miles) in area – roughly three times the size of New York's Central Park – and can be more than 10 meters (33 feet) thick.
