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.

A new book paints a daunting and detailed picture of earth’s natural ice under threat, and explains why what happens in the Arctic doesn’t stay in the Arctic.
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.
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.
Posing as an interplanetary flight attendant in an upcoming show, researcher Christine McCarthy will lead a geological journey through the solar system.
Citizen scientists can gather data to help uncover how snow is changing over time.
A new study shows that even minor deterioration of ice shelves can instantaneously hasten the decline of ice hundreds of miles landward.
One of the largest icebergs ever – roughly the size of Delaware – just broke off of Antarctica, according to scientists who have been observing the area for years. While it’s not unusual for ice shelves to calve, many in the climate community fear that the breaking of Larsen C may be a signal of other events to come.
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica’s ice during the brief summer. Many of the newly mapped drainages are not new, but the fact they exist at all is significant; they appear to proliferate with small upswings in temperature, so warming projected for this century could quickly magnify their influence on sea level.
