Had lots of fun working on this! Atmospheric rivers can induce strong melt episodes, which tend to be underestimated in reanalyses and models. These models strongly diverge in their simulation of clouds and the surface energy balance 🌨️☼ Big thanks to @ruthmottram.bsky.social and my other co-authors!

🚨 New @oceaniceeu.bsky.social preprint🚨 why has Antarctica stopped (net) losing mass, in spite of increased discharge?
Declining sea ice is part of the answer but increasingly heavy and frequent atmospheric rivers are most important factor.

New look at the landscape beneath Antarctica 🇦🇶
Without the 27.17 million km³ of ice.
This clearly shows that much the West-Antarctic Ice Sheet is below sea level.
That's why it melts rapidly in a warmer climate, like it did ~120,000 years ago during the Eemian interglacial.
