Sixty percent of the world's fresh water is bound up in Antarctic ice sheets. Thirty million cubic kilometers of ice is perhaps a difficult number to grasp. But if absolutely all Antarctica's ice melted, the seas would rise ...

In West Antarctica, the 80-mile-wide stream of sliding ice at the heart of Thwaites Glacier is likely to creep outward over the next 20 years, a change that could speed up ice loss, new research finds.

Major ice streams can shut down, shifting rapid ice transport to other parts of the ice sheet, within a few thousand years. This was determined in reconstructions of two ice streams, based on ice-penetrating radar scans of ...
