Scientists Warn of Melting Ice Sheet, Rising Sea Level – WSJ.com

Six rapidly melting glaciers in Antarctica are destabilizing one of the world’s largest ice sheets, a process which, if unchecked, could release enough water to raise sea levels world-wide significantly. NASA climatologist Drew Shindell explains the impact on the News Hub.

Six rapidly melting glaciers in Antarctica are destabilizing one of the world’s largest ice sheets, a process which, if unchecked, could release enough water to raise sea levels world-wide significantly in centuries to come, two groups of scientists said Monday.

On the basis of decades of satellite measurements and aircraft observations, researchers at the National Aeronautics and Space Administration’s Jet Propulsion Laboratory and the University of California at Irvine calculated that the glaciers’ retreat may have already “reached the point of no return.”

An ice sheet is part of a vast, continent-size ice cap—often miles thick—that is drained by flowing glaciers the way a lake is drained by streams.
