Shrinking glaciers have created a new normal for Greenland's ice sheet – consistent ice loss for the foreseeable future

Greenland's glaciers have retreated so far that they can no longer support the ice sheet that feeds them. The ice sheet system has reached a new normal of consistent annual ice loss.
