New Studies Say Greenland’s Ice Sheet Could Melt Far Faster Than Scientists Believed

Scientists who study climate change have warned for years that sea level rise due to the melting polar ice caps could devastate coastal cities. But the scale of the damage—and how quickly it would unfold—has remained a matter of debate. Now, two new studies published in the journal Nature undercut key assumptions about Greenland's ice sheet—a key site of melting ice—and shows just how much more scientists need to learn to understand how devastating sea level rise may be.
