Hidden meltwater within Greenland’s Ice Sheet is challenging current climate models and reshaping sea-level rise predictions.

Scientists have identified more than 50 new lakes of liquid water lying under the Greenland Ice Sheet. Only four had previously been detected. Antarctica hides some 470 lakes beneath its ice but ...

The maps here show the world as it is now ... West Antarctica: Like the Greenland ice sheet, the West Antarctic one was apparently much smaller during earlier warm periods. It's vulnerable ...

This is one of thousands of giant sinkholes, or moulins, in Greenland where water is draining through the ice sheet into the ocean. Meltwater from Greenland is the largest current contributor to ...

Now, a new study claims that we may have a small window of opportunity to turn things around and save the melting ice sheet that covers Greenland. The vast ice sheet that covers most of Greenland ...
