For decades, Antarctica seemed to defy global warming. Since satellites began monitoring the poles in the late 1970s, the ...

Antarctic sea ice is shrinking faster than expected. New research shows how winds, ocean heat, and feedback loops caused this ...

The change has been so extreme that vast areas of ice equivalent to the size of Greenland have melted, experts say ...

Arctic sea ice hit its second straight record-low winter peak in 2026, driven by unusually warm conditions in key regions.

Triple threat revealed: Researchers identified three linked processes behind unprecedented Antarctic sea ice loss since 2015, including wind-driven upwelling of warm water and persistent surface heat.

Global sea ice reached a new record low in February, according to the European Union's Copernicus Climate Change Service. This data, which combines the extent of sea ice from the Arctic and Antarctic, ...

University of Utah mathematics and climate researchers are building new models for understanding the dynamics of sea ice, which is not as solid as you might think. Polar sea ice is ever-changing. It ...

Global sea levels may rise faster than previously expected, suggests a new study in Nature Communications. The reason is that ...

Photos from space show how the ice sheet in Greenland has changed as melting glaciers contribute to sea-level rise.

A Dec. 28 Facebook post (direct link, archive link) shows two maps of Antarctic sea ice dated Dec. 26, 1979, and Dec. 25, 2023. The more recent map seems to show the ice occupying a larger area.

Antarctica is the world’s great cooling unit. This vital part of Earth’s climate system is largely powered by the annual freeze and melt of millions of square kilometres of sea ice around the ...
