Scientists say next few years vital to securing the future of the West Antarctic Ice Sheet

03.06.2025 – Collapse of the West Antarctic Ice Sheet could be triggered with very little ocean warming above present-day, leading to a devastating four metres of global sea level rise to play out over hundreds of years according to a study now published in Communications Earth & Environment, co-authored by the Potsdam Institute for Climate Impact Research (PIK). However, the authors emphasise that immediate actions to reduce emissions could still avoid a catastrophic outcome.

Incidentally, while this is happening in the US, we have been working quite hard on the @polarportal (well @MartinStendel + out @dmidk colleagues have, I've mainly tried to make helpful comments), the old website is still up giving the latest on #Arctic #seaice #Greenland #icesheet and other datasets, but there's some fancy new stuff on the pipeline.

'The ice melted beneath our feet': The huskies that revealed the rapid shrinking of Greenland's ice.

In 2019, climate scientist Steffen Olsen took a startling photo of huskies appearing to walk on water.

The photo quickly went viral as it revealed the reality of Greenland's rapidly melting ice.

#Scientists discover hidden 'plumbing' that's driving #Antarctic #icesheet into the #ocean
Maps created by combining different models of #glaciers and ice sheets reveal the way water is flowing deep beneath #Antarctica's ice. Understanding how these vary is important for accurately predicting how much ice will flow into the ocean, and how quickly it will move. Current models predict that ice melt from Antarctica could result in #sealevelrise up to 12in (30cm) by 2100.
