🚨 New preprint out🚨 now, why has Antarctica stopped (net) losing mass?
We explore how declining sea ice but mostly increasingly heavy and frequent atmospheric rivers have actually led to a small increase in the mass of #Antarctica, in spite of increased discharge from outlet glaciers.

The increase is unlikely to be sustained, and a small increase in calving or discharge over the grounding line can easily turn it upside down, but nevertheless another long-term prediction about the Antarctic appears to becoming true.

Lots of important subtleties in this one!

In review at Nature communications but I feel it's too important to wait for the review process.
