Sustained mass loss of the northeast Greenland ice sheet triggered by regional warming

The Greenland ice sheet is a large contributor to sea-level rise primarily because of the increased speed of its glaciers in the southeast and northwest. This study looks at a previously stable ice stream in northeast Greenland, and finds that it is thinning due to regional warming. This region drains 16% of the ice sheet but has not figured in model projections of sea-level rise, indicating an under-estimation of Greenland contributions.
