Antarctic ice melt triggers further melting: Evidence for cascading feedbacks 9,000 years ago

A study has revealed that the substantial retreat of the East Antarctic Ice Sheet (EAIS) approximately 9,000 years ago was driven by a self-reinforcing feedback loop between ice melt and ocean circulation.

"Ground temperatures in #EastAntarctica have soared more than 50 degrees (28 Celsius) above normal in the second major #heatwave to afflict the region in the past two years. This historic warm spell could persist for another 10 days and is an ominous example of the major temperature spikes this polar climate could experience more frequently in a warming world."

Antarctic temperatures soar 50 degrees above norm in long-lasting heat wave

This historic warm spell in East Antarctica is an ominous example of the temperature spikes this polar climate could experience more of in a warming world.

"Researchers at Stanford have shown that the Wilkes Subglacial Basin in #EastAntarctica, which holds enough ice to raise global #SeaLevels by more than 10 feet, could be closer to runaway melting than anyone realized."

"This area has conditions that we could imagine changing," Schroeder said. "And if warm ocean water gets there, it's going to 'turn on' a whole sector of Antarctica we don't normally think about as a contributor to sea level rise."

Currently stable parts of East Antarctica may be closer to melting than anyone has realized

In a warming climate, meltwater from Antarctica is expected to contribute significantly to rising seas. For the most part, though, research has been focused on West Antarctica, in places like the Thwaites Glacier, which has seen significant melt in recent decades.

A heatwave in Antarctica totally blew the minds of scientists. They set out to decipher it – and here are the results

A heatwave in 2022 redefined scientific expectations of the Antarctic climate. Now the global community must prepare for what a warmer world may bring.

At sustained >2°C global warming, large subglacial basins in #EastAntarctica could also cross their TPs, and irreversible collapse of the Greenland and West Antarctic ice sheets is likely to become locked in, with far-reaching impacts for the livelihoods of millions of people. /6

Global Sea Level rise projections grossly under-estimated says major peer reviewed science #Cryosphere report, 'Two Degrees is Too High'. Report is by International Cryosphere Climate Initiative, estimates that 12 to 20 metres is likely from a 2C rise in temperature with eventual dissolution of most of Greenland, West Antarctica and parts of East Antarctica.

"We cannot negotiate with the melting point of ice."

"last year the #temperature reached an incredible 38.5°C above the mean in #EastAntarctica. Now we are seeing that the extent of #SeaIce around the continent is at an all-time low for this time of the year. This is worrying because much more winter sea ice should be forming."

Antarctica vulnerable to extreme events

According to the World Meteorological Organization, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region.

Glacial rocks reveal the geology hidden beneath the East Antarctica Ice Sheet

A trove of ancient rocks collected from glacial moraines has literally revealed the deep story of one of the most underexplored environments on the planet—the rocks and mountain belts hidden beneath the East Antarctica Ice Sheet. Before this study, scientists had only the vaguest idea of when, how and why the mountains and landscapes now buried under the world's largest ice sheet had formed.
