Scientists have discovered ancient river valleys preserved beneath the East Antarctic ice sheet. The landscape, shaped by rivers and glaciers over millions of years, has remained untouched for at least 14 million years. The finding comes as larger volumes of warm water are bathing the undersides of West Antarctica's ice shelves, posing a threat to rising sea levels. A study by the British Antarctic Survey suggests that the melting of the West Antarctic Ice Sheet is inevitable, regardless of efforts to reduce fossil fuel use. The most comprehensive effort to predict the impact of global warming on the West Antarctic Ice Sheet has found that there is little humanity can do to stop its ice shelves from melting.

Icefin, a remotely operated ocean vehicle, has explored melting and freezing in Antarctic ice shelf basal crevasse. A new study in Science Advances details Icefin’s observations: https://t.co/clRh3shZ3F https://t.co/SxHk9PvxQN
Sea-levels are likely rising faster than scientists had feared because Antartica's glaciers are melting from beneath. https://t.co/jug2Eb1djD

The preserved terrains of Antarctica’s balmier past date back tens of millions of years, and contain clues about our future in a warming world. https://t.co/roghGorGft

No matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an “unavoidable” melt, a new study found. https://t.co/4nNkLRAuTA

Even if we introduce countermeasures, West Antarctica's ice shelves will probably fall apart in the coming decades. https://t.co/hgrbctGlFL

A paper in @NatureComms reports an ancient river-carved landscape preserved under the East Antarctic Ice Sheet. Continental-scale ice retreat has not touched this newly discovered landscape for at least 14 million years. https://t.co/v2LxXnO7ZS https://t.co/jrUqWSF8Dh

Isn't it fair to say, with some reasonable assumptions in mind, that a near-term partial/total collapse of the West Antarctic Ice Sheet is almost certain? 🧵
As the planet warms, larger volumes of warm water are bathing the undersides of West Antarctica’s ice shelves, a threat that could add to rising sea levels around the globe. https://t.co/W9U9piq2Uq
The West Antarctic ice sheet is set to melt faster even if the world rapidly cuts emissions, according to a new study. That could lead to more significant sea level rise https://t.co/J7NtKgojzk
