Greenland's Glaciers Develop Stretch Marks As They Accelerate

New submitter dywolf writes: NASA run Operation IceBridge has been monitoring and mapping ice sheets for the past eight years. They develop these maps in 3D using laser equipped aircraft to measure ice thickness. As glaciers reach the coast, they begin to accelerate, which causes crevasses to appear, which are essentially stretchmarks in the glacial strata. While a natural part of glaciers as they travel to sea, the glaciers of Greenland have increased in speed by 30% in the past decade. Jakobshavn Isbrae os Greenland's fastest glacier, and is now moving at four times faster than it did 20 years ago.
