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 the Greenland ice sheet, that a team of researchers led by the Alfred Wegener Institute have just presented in the journal Nature Geoscience.
