Ice sheets are important because they are at sea level, where climate change shows up. Melting ice sheets can be an early warning sign of global warming. We need to know what's happening to the ice because it is a major component of the Earth's climate system; it affects the climate and is effected by it.
The rate at which the area's ice is melting has increased 77% since 1973, and there are several reasons, researchers said. The ice sheet there, unlike those in much of east Antarctica, is attached to a bed below sea level.That means ocean currents can deliver warm water at the glaciers' base, or grounding lines -- places where the ice attaches to the bed, NASA said.he ice sheet there, unlike those in much of east Antarctica, is attached to a bed below sea level.
