"That transition took thousands of years, not two decades." ...

A key layer of water around Antarctica is getting saltier, potentially shifting storm tracks and accelerating sea-level rise, ...

Antarctic sea ice ocean chemistry: new research in Nature Climate Change finds that sea ice collapse since 2016 has already ...

The AMOC acts as a heat pump, carrying warm salty surface seawater up from the tropics and the Gulf of Mexico. As it pushes ...

Every southern spring and summer, sea ice around Antarctica melts with the change of season. The melt injects fresh water ...

Declining Antarctic sea ice has abruptly reversed the salinity and density of the Antarctic Intermediate Water, risking ...

Antarctica’s Thwaites Glacier may be melting twice as much as previously predicted, even without additional global warming.

Declining ice has led to saltier and denser water that could influence atmospheric circulation and weather in the Southern ...

Gayen and his colleagues obtained direct observational evidence of this change. The researchers analyzed data from the global Argo program—a network of nearly 4,000 robotic floats that measure the ...

Off the coast of Antarctica, the sea ice retreated toward the southernmost continent and, like a bottle cap taken off a soda bottle, that reduced pressure slowed down a process of critical carbon ...

The Antarctic Intermediate Water (AAIW)—a vast layer of fresh water spanning much of the Southern Hemisphere's ocean—has ...

A 34,400-square-mile hole opened in Antarctic sea ice off Breid Bay, a first in 45 years of satellite records.
