A Saltier Southern Ocean Could Cause More Melting Ice in Antarctica
Learn why a surge in the Southern Ocean’s salinity is an alarming sign for the future of Antarctic ice.

Antarctica’s slow collapse caught on camera—and it’s accelerating
Long-lost 1960s aerial photos let Copenhagen researchers watch Antarctica’s Wordie Ice Shelf crumble in slow motion. By fusing film with satellites, they discovered warm ocean water, not surface ponds, drives the destruction, and mapped “pinning points” that reveal how far a collapse has progressed. The work shows these break-ups unfold more gradually than feared, yet once the ice “brake” fails, land-based glaciers surge, setting up meters of future sea-level rise that will strike nor…

Microplastics and melting ice reveal deepening crisis in Antarctica
Glaciers melting rapidly, fields of moss expanding, water streaming off ice shelves once frozen solid: these are just a few of the impacts of climate change observed by a team of 57 researchers during a 70-day voyage around the Antarctic coast on the Russian icebreaker Akademik Tryoshnikov. The expedition also revealed the presence of microplastics […]

Antarctica’s sea ice is changing, and so is a vital part of the marine food web that lives within it
When sea ice forms later, the communities of tiny algae that live within it change too. Detecting these early signals now could help us adapt to a changing world.
