Antarctica’s ice, ocean, and ecosystems are approaching tipping points that could trigger irreversible global impacts.

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 collapsing sea ice around the Antarctic continent has led to a doubling in the number of icebergs calving from ice sheets and a surge in sea temperatures, and the impacts are growing more severe ...

Deep ocean water in the Antarctic is heating up and shrinking, with potentially far-reaching consequences for climate change and deep ocean ecosystems, according to a report. “Antarctic bottom water” ...

Climate models suggest that climate change could reduce the Southern Ocean's ability to absorb carbon dioxide (CO2). However, ...

Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss. The ...

S omething may be stirring in the world’s largest oceanic current. New research suggests that this vast conveyor belt of cold ...

Antarctic sea ice recently reached an all-time record wintertime low, scientists from the National Snow and Ice Data Center announced. The mark was set "by a wide margin," the center said in a release ...

The acidity of Antarctica’s coastal waters could double by the end of the century, threatening whales, penguins and hundreds of other species that inhabit the Southern Ocean, according to new CU ...
