Scientists finally understand why Antarctica froze long before the Arctic - Futura-Sciences
The research shows that the creation of an escarpment, plateau, and mountain region in East Antarctica produced the high terrain needed for snow and ice to build up. The process began when Antarctica and Africa started pulling apart during the Jurassic Period, between 201 and 143 million years ago. Powerful...
Antarctica gained a record 695 billion tons of ice. Scientists found the surprising reason
East Antarctica gained an astonishing 695 billion tons of ice between 2021 and 2023, temporarily slowing Antarctica’s long-term decline. Researchers found that warming thousands of miles away in the tropical ocean altered atmospheric circulation and funneled moisture toward the continent, triggering exceptionally heavy snowfall.
Antarctica developed a continental-scale ice sheet 34 million years ago while Earth was about 5°C warmer than today — helped by slow-moving mantle waves that had spent more than 100 million years lifting its interior high enough for permanent ice to survive.
A 2026 modelling study links East Antarctica’s high plateau to mantle processes begun during Jurassic breakup, while retaining falling carbon dioxide as the main trigger for glaciation.
Forces deep inside Earth helped Antarctica freeze before the Arctic
Scientists may have solved the mystery of why Antarctica froze millions of years before the Arctic. Slow-moving waves deep inside Earth gradually lifted East Antarctica, building mountains and a high plateau where snow and ice could survive even in a much warmer world. Once glaciers took hold, their bright surfaces reflected sunlight and helped cool the region further.
Scientists discover giant fan-shaped structure beneath Antarctica's ice sheet: The hidden structure rewriting Earth's ancient history
For decades, Antarctica has been treated as a kind of frozen time capsule, a place where evidence of Earth's deep past sits preserved, undisturbed, beneath layers of ice that have built up over millions of years. As per the study published in Nature Geoscience, scientists have now uncovered something remarkable within that buried record: an enormous, fan-shaped geological structure stretching across a huge swath of East Antarctica, hidden entirely from view beneath the ice.
Scientists have detected a giant fan-shaped structure buried beneath the East Antarctic Ice Sheet, suggesting the frozen continent may be hiding the geological scars of the breakup that helped separate Antarctica from Australia
East Antarctica can look, from above, like the quiet half of the frozen continent: old, thick, cold and buried under kilometres of ice. But beneath that ice, new mapping suggests the bedrock may carry the shape of a much more violent past. In a Nature Geoscience study published in June 2026, researchers described a giant […]

A mysterious geological structure that resembles a human hand with outstretched fingers has been revealed beneath East Antarctica. The discovery shows the frozen continent still hides many geological secrets.
Scientists discover vast hidden structure beneath Antarctica’s ice
A giant fan-shaped network of hidden basins has been discovered beneath East Antarctica, revealing that several well-known subglacial features are actually part of one massive geological structure. The finding sheds new light on Antarctica’s ancient tectonic history and could help scientists better understand how the ice sheet behaves today.
Antarctica is melting from below and scientists say it’s worse than expected
Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up melting from below. Even regions of East Antarctica once considered relatively stable may be far more vulnerable than scientists realized. Researchers warn that current climate models may be missing this dangerous process entirely, meaning future sea level rise could be underestimated.
