Researchers make first map of thawed areas under Greenland Ice Sheet

In a new study in the Journal of Geophysical Research: Earth Surface, researchers have produced the first map showing what parts of the bottom of the massive Greenland Ice Sheet are thawed - key information in better predicting how the ice sheet will react to a warming climate.

From a Glacier's Perspective
Alaska's Sater Glacier not retaining snowcover

Landsat images reveal that Alaska's Sater Glacier is not retaining snowcover, writes Mauri Pelto, indicating that the glacier cannot survive the current climate.
