Phytoplankton across most of the Arctic Ocean are now starving for nitrogen rather than struggling for light, a shift that ...

"The changes we report suggest that the Arctic Ocean ecosystem passed a tipping point around 2009." ...

Scientists succeeded in thickening and lightening Arctic ice using seawater in an innovative climate experiment.

Using old satellite radar techniques, scientists have developed a new way of measuring the true extent of an understudied and ...

Amid all the changes in Earth's climate, sea ice in the stormy Southern Ocean surrounding Antarctica was, for a long time, an odd exception. The maximum winter sea ice cover remained steady or even ...

A new study reveals that Arctic sea ice loss is depleting a key ocean nutrient, threatening plankton, marine life, and food webs ...

Two companies are aiming to preserve Arctic ice by pumping water onto the sheet and letting it freeze, but only one of the ...

Since satellites began monitoring the poles in the late 1970s, the seasonal growth and retreat of Antarctic sea ice – frozen seawater that expands around the continent each winter – appeared ...

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 ...

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 ...

Vanishing Antarctic sea ice could lead to more storms in the Southern Ocean, new research shows. Scientists found that reduced Antarctic sea ice coverage in 2023 caused the ocean to lose extra heat to ...
