How Catastrophic Floods May Have Carved Greenland’s ‘Grand Canyon’
In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.

Scientists Link Climate Change to Melting in West Antarctica
A new study shows, for the first time, evidence of a link between human-caused global warming and melting of the West Antarctic Ice Sheet.

Warm Autumn Winds Could Strain Antarctica’s Larsen C Ice Shelf
New research shows that the Larsen C ice shelf—the fourth largest ice shelf in Antarctica—experienced an unusual spike in late summer and early autumn surface melting in the years 2015 to 2017.

Deep-Sea Drillers Investigate Shedding of Antarctic Icebergs
Scientists are sailing to remote areas of the Southern Ocean to drill cores from the bottom that they hope will contain clues to past rapid changes in the Antarctic ice, and how it may react to warming climate today.
