The climate crisis is warming Antarctica fast, with potentially disastrous consequences. Now scientists have modeled the best- and worst-case scenarios for climate change in Antarctica, demonstrating just how high the stakes are—but also how much harm can still be prevented.

A new study lays out the best- and worst-case scenarios for a warming Antarctica. Which one becomes reality is entirely up to us.

Many experts had thought sharks didn’t exist in the frigid waters of Antarctica before this sleeper shark lumbered warily and briefly into the spotlight of a video camera, researcher Alan Jamieson said this week. The shark, filmed in January 2025, was a substantial specimen with an estimated length of between 3 and 4 meters (10 and 13 feet).

Antarctic Peninsula projections show accelerating ice loss, warming oceans and global sea level impacts tied to greenhouse gas emissions.

The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference for all topographical features. This particular geoid was constructed by ESA’s steady-state Ocean Circulation Explorer (GOCE) mission. Credit: ESA.

Scientists have found microplastics inside Antarctica's only native insect, the Belgica antarctica. Discover what this means for the fragile polar ecosystem and global plastic pollution.

Pink boulders led scientists to a massive granite formation buried under Antarctica’s ice, solving a decades-old geological mystery.

Early on Tuesday, Feb. 26, a rare annular solar eclipse created a “ring of fire” over Antarctica, while South Africa and Indian Ocean locations saw partial phases.
