In their new paper for the Geological Society of America journal Geology, Dulcinea Groff and colleagues used radiocarbon ages (kill dates) of previously ice-entombed dead black mosses to reveal that glaciers advanced during ...

Pine Island Ice Shelf in West Antarctica, which holds back enough ice to raise sea levels by 0.5 meters, could be more vulnerable to complete disintegration than previously thought. A new study led by British Antarctic Survey ...

As Antarctica's slow rivers of ice hit the sea, they float, forming ice shelves. These shelves extend the glaciers into the ocean until they calve into icebergs.

The fate of the world's biggest ice sheet still rests in our hands if global temperature increases are kept below the upper limit set by the Paris Agreement on climate change.

Mountain glaciers are essential water sources for nearly a quarter of the global population. But figuring out just how much ice they hold—and how much water will be available as glaciers shrink in a warming world—has ...

Glacier ice is usually thought of as brittle. You can drill a hole in an ice sheet, like into a rock, and glaciers crack and calve, leaving behind vertical ice cliffs.

A team of scientists is sailing to "the place in the world that's the hardest to get to" so they can better figure out how much and how fast seas will rise because of global warming eating away at Antarctica's ice.

Ice losses from Thwaites Glacier in West Antarctica are currently responsible for roughly 4 percent of the global sea-level rise. This figure could increase, since virtually no other ice stream in the Antarctic is changing ...

For decades, the ice shelf helping to hold back one of the fastest-moving glaciers in Antarctica has gradually thinned. Analysis of satellite images reveals a more dramatic process in recent years: From 2017 to 2020, large ...
