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 ...

Sea ice in the Antarctic Ocean had been growing for decades, but now, a sudden trend downward could spell serious trouble.

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

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 around the polar regions grows and melts with the seasons. In Antarctica, sea ice typically hits its minimum coverage at the end of the Southern Hemisphere’s summer around February.

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.

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 ...

Understanding the dynamics of ice mass on Antarctica is thus essential. The recent Antarctica shift makes only a small dent in the overall ice loss from 2022, but comes as a surprise nonetheless.

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 ...

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 ...
