Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ...

In recent years, the Southern Ocean has undergone one of the most dramatic environmental shifts observed anywhere on Earth.

A study published Monday in the Proceedings of the National Academy of Sciences found that increases in salinity in seawater near the surface could help explain some of the decrease in Antarctic sea ...

There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometers of ...

The claim: Changes in Antarctic sea ice coverage shows global warming is not happening. A Dec. 28 Facebook post (direct link, archive link) shows two maps of Antarctic sea ice dated Dec. 26, 1979 ...

A new study found that Antarctic ice shelves have shrunk by at least 30% since 1997. That's enough ice that if it melted, it would cover the continental US in 3 feet of water.

Antarctica’s huge glacial ice expanse and the surrounding sea ice cover are critical to regulating the climate, because it reflects the sun’s energy back to the atmosphere and space.

Sea ice that covers the ocean around Antarctica hit a record low surface area in the winter, a preliminary analysis of US satellite data shows, and scientists fear the impact of climate change is ...

In the last few years, Antarctic sea ice has been behaving erratically. Sea ice cover has been much more variable than it used to be, with anomalies lasting much longer than previously documented.

Sea ice at both the top and bottom of the planet continued its decline in 2024. In the waters around Antarctica, ice coverage shrank to near-historic lows for the third year in a row. The ...

Then, as Antarctic winter approaches, the ice begins to grow again. At its most expansive, the sea ice covers an area the size of Antarctica itself – essentially, the frozen continent doubles in ...

There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometres of ...
