Greenland bedrock drilling project to understand past, future ice sheet melting


UNIVERSITY PARK, Pa. — The Greenland Ice Sheet holds enough water to raise sea levels nearly 24 feet, yet it remains difficult to predict the rate of melt and possible tipping points in the stability of the ice sheet.

Climate change is now causing Greenland to shed ice rapidly, and even a few feet of sea level rise may have grim implications for coastal cities and low-lying islands.
