Arctic ice loss is worrying, but the giant stirring in the south could be even worse

Arctic ice loss is worrying, but the giant stirring in the south could be even worse

A record start to summer ice melt in Greenland this year has drawn attention to the northern ice sheet. We will have to wait to see if 2019 continues to break ice-melt records, but in the rapidly warming Arctic the long-term trends of ice loss are clear.

Huge Cavity in Antarctic Glacier Signals Rapid Decay

Huge Cavity in Antarctic Glacier Signals Rapid Decay

A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers' undersides in calculating how fast global sea levels will rise in response to climate change.
