Giant trains of warm, moist air are playing havoc with Arctic sea ice during the season when it should be recovering from summer melting.

As the planet’s ice disappears, it’s exposing new surfaces, opportunities, and threats — including valuable mineral deposits, archaeological relics, novel viruses, and more.

Sea ice in the Southern Ocean retreats each year much faster than it develops. This has puzzled scientists, but the explanation turns out to be simple.

High-resolution satellite images allowed researchers to do a more comprehensive head count than ever before, and revealed patterns in the seals’ distribution.

A launch event will include clips from the film; discussion by Iñupiaq elders, scientists and the filmmaker; and audience Q&A.

A recent study provides a rough timeline, but there’s still time to save them if we cut our carbon emissions.

Seals have been a staple for the coastal village of Kotzebue for generations. Rapid changes in sea ice driven by ocean warmth are presenting a challenge for hunters.

Researchers have zeroed in on what they call the Last Ice Area, where the last year-round Arctic ice, and associated ecosystems may–or may not–survive in a warmer future.

The movement of sea ice between Arctic countries is expected to significantly increase this century, raising the risk of more widely transporting pollutants like microplastics and oil, according to new research.

Working as an Antarctic field scientist, I witnessed the destruction provoked by a rapidly warming planet. But I also found inspiration.
