Unprecedented melting of Greenland's ice sheet this month has stunned NASA scientists. In just a few days, the melting had dramatically accelerated and an estimated 97 percent of the ice sheet surface had thawed by July This last happened in
Greenland ice is melting -- even from below: Heat flow from the mantle contributes to the ice melt
The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere.

The Greenland ice sheet is poised for another record melt this year, and is approaching a "tipping point" into a new and more dangerous melt regime in which the summer melt area covers the entire land mass
A new computer model of accumulated carbon emissions predicts the likelihood of crossing several dangerous climate change thresholds. These include global temperature rise sufficient to lose the Greenland Ice Sheet and generate .
