Edge of Pine Island Glacier's ice shelf is ripping apart, causing key Antarctic glacier to gain speed

Pine Island Glacier's ice shelf lost about one-fifth of its total area between 2017 and 2020, in three dramatic collapses. Meanwhile the glacier sped up by 12 percent. The rest of the ice shelf, the authors say, could disappear much sooner than previous studies had suggested.
