Why is #Antarctica temporarily gaining mass... And why it isn't necessarily good news..

"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,”

H5N1 bird flu kills more than 50 skuas in first Antarctica wildlife die off
For the first time, deadly H5N1 bird flu has been confirmed as the cause of a wildlife die-off in Antarctica, killing more than 50 skuas during the 2023–2024 summers. Researchers on an Antarctic expedition found the virus ravaging these powerful seabirds, with some suffering severe neurological symptoms—twisted necks, circling behavior, and even falling from the sky. While penguins and fur seals were examined, skuas emerged as the primary victims, especially on Beak Island, where a mass die…

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.

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.
