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 s…

Antarctica has lost 10 times the size of Greater Los Angeles in ice over 30 years, satellite data reveal
A comprehensive 30-year study led by University of California, Irvine glaciologists has produced a circumpolar ice grounding line migration map of Antarctica. An amalgamation of three decades of satellite data compiled and analyzed by the researchers revealed that while most of Antarctica remains remarkably stable, vulnerable sectors are losing grounded ice equivalent to the size of Greater Los Angeles every three years.

Deep-ocean heat has been marching closer to Antarctica, reveals long-term study
A new decades-long study of oceanographic data provides the first evidence that deep-ocean heat has moved closer to Antarctica, threatening the fragile ice shelves that fringe the continent.

How Antarctica warmed by 28°C in the depths of winter – and what it signals for the decades ahead
A new study highlights one of the largest temperature anomalies recorded anywhere, ever.

Atmospheric rivers and winter sea ice drive recent reversal in Antarctic ice mass loss: #Antarctica

"What makes this remarkable is that the ice sheet isn't losing less ice – it's actually losing more. Ice discharge by iceberg calving has increased by nearly 100 gigatonnes per year compared to the previous two decades. The snowfall surge has simply outpaced it – for now,”

Antarctica just saw the fastest glacier collapse ever recorded #Antarctica

Antarctica just saw the fastest glacier collapse ever recorded
Antarctica’s Hektoria Glacier stunned scientists by retreating eight kilometers in just two months, with nearly half of it collapsing in record time. The rapid breakup was driven by a flat, underwater bedrock surface that allowed the glacier to suddenly float and fracture from below. Satellite and seismic data captured the dramatic chain reaction in near real time. The findings raise concerns that much larger glaciers could one day collapse just as quickly.
