When sea ice melts and refreezes, it stirs vortices that pull warm deep water up, eroding Antarctica's shrinking ice shelves.

A team of researchers including oceanographer Lia Siegelman of UC San Diego’s Scripps Institution of Oceanography co-authored ...

Containing around 750,000 cubic miles of ice – enough to fill Wembley Stadium nearly 3 billion times – the West Antarctic Ice Sheet is a rich reservoir of precious frozen freshwater. Now, scientists ...

Antarctica faces abrupt and irreversible changes impacting ice sheets, oceans, and ecosystems. Scientists warn of global consequences for sea levels and climate. The West Antarctic Ice Sheet is at ...

Fast-moving ocean motions under the Antarctic ice act like storms and melt ice quickly. These forces could speed up sea-level ...

The study, published on 14 November in Science Advances, demonstrates how freshwater from the south can slow down the weakening of this crucial ocean current.

Researchers at the University of California, Irvine and NASA's Jet Propulsion Laboratory have identified stormlike ...

Collapse of the West Antarctic Ice Sheet could be triggered with very little ocean warming above present-day, leading to a devastating four metres of global sea level rise to play out over hundreds of ...

When snow falls on the ice sheet, where subzero temperatures ensure it doesn’t melt. Antarctic temperatures regularly reach ...

Scientists are increasingly concerned that the planet is headed for massive, irreversible changes due to global warming. In ...

Researchers found Antarctic melt only delays - never prevents - the AMOC’s long decline, with major impacts on weather, seas, ...
