Antarctica

Antarctica’s west coast is missing an area of winter sea ice the size of France. Temperatures have climbed up to 45 degrees Fahrenheit above normal, stopping ice from forming in the dead of Antarctic winter.

Researchers have mapped a massive fan-shaped network of basins beneath the East Antarctic Ice Sheet, linking several previously studied features into one large geological structure. The discovery, published in a 2026 study, offers new insights into the continent's tectonic past and its influence on current ice movement.

Scientists have determined that Earth's most powerful ocean current, the Antarctic Circumpolar Current, formed through shifting continents and strong winds rather than solely from opening ocean gateways. This development around 34 million years ago helped draw down atmospheric carbon dioxide, contributing to a global cooling that led to the Antarctic Ice Sheet. The findings come from climate simulations published in the Proceedings of the National Academy of Sciences.

New studies indicate that stronger winds and warming deep ocean water have triggered a sharp decline in Antarctic sea ice since 2016. Previously expanding, the ice reached a record high in 2014 before plummeting to record lows. Researchers link this shift to wind-driven upwelling of circumpolar deep water.

In 2023, Hektoria Glacier on Antarctica's Eastern Peninsula retreated eight kilometers in just two months, marking the fastest such event recorded. Nearly half of the glacier broke apart due to its position over a flat underwater bedrock. The discovery, detailed in a new study, highlights vulnerabilities in other Antarctic ice features.

Scientists have finally uncovered the cause behind the crimson liquid emerging from Antarctica's Taylor Glacier. Known as Blood Falls, this phenomenon has puzzled researchers since its discovery over a century ago. The latest findings explain the reddish water's underground journey to the surface.
