Increasing extreme melt in northeast Greenland linked to foehn winds and atmospheric rivers ...
The Greenland Ice Sheet has been losing mass at an increased rate in recent decades. In northeast Greenland, increasing surface melt has accompanied speed-ups in the outlet glaciers of the Northeast Greenland Ice Stream, which contain over one meter of sea level rise potential. Here we show that the...

The Greenland Ice Sheet has been losing mass at an increased rate in recent decades.
