Destabilization of the Northeast Greenland Ice Stream
The Greenland Ice Sheet (GrIS) has been one of the largest contributors to global sea level rise over the last 20 years, accounting for c. 0.5 of a total of c. 3.2 mm yr-1. A significant portion of this contribution is associated with the speed up of glaciers in southeast and northwest Greenland. He...
