Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point. That is the conclusion by Niklas Boers from Potsdam ...

In 1966, US Army scientists drilled down through nearly a mile of ice in northwestern Greenland—and pulled up a fifteen-foot-long tube of dirt from the bottom. Then this frozen sediment was lost in a freezer for decades. ...

If human societies don't sharply curb emissions of greenhouse gases, Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.

The world's second-largest ice sheet, and the single largest contributor to global sea-level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming ...

Ice on the Greenland Ice Sheet doesn't just melt. The ice actually slides rapidly across its bed toward the ice sheet's edges. As a result, because ice motion is from sliding as opposed to ice deformation, ice is being moved ...
