Researchers measuring the salinity of the Southern Ocean did find unexpected results, but some online reports got the details ...

Antarctic sea ice began to change rapidly in 2015 and 2016. Since then it has remained well below the long-term average.

The dramatic loss of sea ice around Antarctica has occurred with the re-emergence of the Maud Rise polynya in the Weddell Sea ...

Sea ice protects Antarctica's coast from ocean waves. On average, about a third of the continent's coastline is exposed over summer. But this is changing. In 2022 and 2023, ...

Summer sea ice in the Arctic Ocean might be gone by the 2030s, no matter what we do to curb emissions of greenhouse gases, study says. Hotspots ranked Start the day smarter ☀️ Funniest cap ...

The ocean around Antarctica is rapidly getting saltier at the same time as sea ice is retreating at a record pace. Since 2015, the frozen continent has lost sea ice similar to the size of Greenland.

Sea ice in Antarctica hit a record low this year and is “on a very steep downward trend,” a sign this complex and isolated region may finally be responding to the climate crisis.

Low sea ice last summer caused several colonies to lose their offspring. Some studies show that the birds could be on the brink of extinction by 2100 if current rates of warming persist.

As sea ice disappears and grows less reflective, the Arctic has lost around a quarter of its cooling power since 1980, and the world has lost up to 15%, according to new research.

Each year, Arctic sea ice expands as the sea surface freezes during the long, dark winter. At its maximum in March, the ice covers nearly the entire Arctic Ocean, almost 6 million square miles.

Antarctica's annual maximum sea ice extent in September 2023 was the lowest on record, with approximately 1.75 million square kilometers less sea ice than normal—an area equivalent to about 6.5 ...
