A global team of scientists including several from Scripps Institution of Oceanography at the University of California San Diego discovered the sudden demise of a large, deep, ice-covered […]

This was taken in the Scotia Sea during the coring campaign in 2007. Credit: Michael Weber New calculations show the rise due to warming would be 30% above forecasts. Global sea level rise associated with the possible collapse of the West Antarctic Ice Sheet has been significantly underestimated in previous […]

Credit: Pixabay/CC0 Public Domain More than a third of the Antarctic’s ice shelf area could be at risk of collapsing into the sea if global temperatures reach 4°C above pre-industrial levels, new research has shown. The University of Reading led the most detailed ever study forecasting how vulnerable the vast […]

Credit: Dr. Sebastian Rosier Researchers have confirmed for the first time that Pine Island Glacier in West Antarctica could cross tipping points, leading to a rapid and irreversible retreat which would have significant consequences for global sea level. Pine Island Glacier […]

Satellite observations have been used to show widespread increases in ice speed across the Getz sector for the first time, with some ice accelerating into the ocean by nearly 50%. Credit: Pierre Dutrieux Glaciers in West Antarctica are moving more quickly from land into the ocean, contributing to rising global […]

Scientists have discovered that glaciers in the Getz region of Antarctica are increasing in speed as they flow towards the ocean. This new research, which includes data from the Copernicus Sentinel-1 mission, will help determine if these glaciers could collapse in the next few decades and how this would affect […]

March 1, 2021 A large iceberg finally split from the Antarctic ice shelf, but another piece stubbornly hangs on. Antarctica’s Brunt Ice Shelf finally calved a large iceberg in February 2021, two years after rifts opened rapidly across the ice and raised concerns about the shelf’s stability. The break was first detected […]

TerraSAR-X pictured the new berg at 23:12 GMT on Saturday Radar satellites got their first good look at Antarctica’s new mega-iceberg over the weekend. The EU’s Sentinel-1 and Germany’s TerraSAR-X spacecraft both had passes over the 1,270-sq-km (490-sq-mile) block, informally named “A74”. Their sensors showed the berg to have moved rapidly […]
