NASA finds what a glacier's slope reveals about Greenland ice sheet thinning

Greenbelt MD (SPX) Dec 21, 2020

As glaciers flow outward from the Greenland Ice Sheet, what lies beneath them offers clues to their role in future ice thinning and sea-level rise contribution. Outlet glaciers are rivers of ice flowing within the cracks of the bedrock and draining into the surrounding sea. They retreat and start to thin as climate warms, and this thinning works its way toward the center of the ice sheet.
