The Greenland Ice Sheet in a Changing Climate, long version
The ice is moving all over Greenland.
The inland ice is in motion and presently more than 205 gigaton per year is lost, working its way into the sea, coursing the oceans to rise. This is a rate of loss, we has never observed before.
Enormous forces are at play here, and the movements are controlled by mechanisms we have only just begun to understand.
