Arctic cyclones may be accelerating sea ice loss by breaking ice into smaller pieces and driving upwelling of warm water. A study links these storms to rapid ice depletion and suggests that tropopause ...

Arctic sea-ice is currently at its smallest recorded extent for the time of year, while Antarctic sea-ice is close to a new ...

A new study published in Communications Earth & Environment gives possible insight into the underprediction of sea ice ...

As Arctic sea ice continues to thin and shrink, an essential feature of its ecosystem—pressure ridges—is becoming ...

Giant cyclones of snow and ice are breaking up thin ice in the Arctic, leading to rapid ice loss events, and it’s happening more now than ever before. A scientist at OU described an unusually powerful ...

Earth passed the 1.5°C warming limit in 2024. The Arctic is warming four times faster than the rest of the world.

Social media posts sharing a graphic comparing sea ice levels in the Antarctic on the same date 45 years apart misrepresent ...

The sea ice in the Arctic was the second lowest on record ... in the journal Science last week found that around half of the decline in Canada's Hudson Bay polar bears from 1979 to 2021 was ...

Scientists have quantified how much climate change has driven the population decline of polar bears living in Canada's Hudson ...

At the same time, surface permafrost will decline to half of its pre-industrial ... This shift will have severe consequences ...

Researchers have developed a concept for an autonomous twin-hull research mothership to study sea ice melt with robots ...

The sea ice decline since 1979 is the sum of numerous VRILEs that individually occur in periods of 5 to 18 days. Cavallo's publication suggests that Arctic cyclones are at least partially to blame.
