If we limit warming to the Paris Climate Agreement of 1.5ºC, then we don't have to worry about dangerous levels of sea-level rise, right? Actually, no. Our research suggests that this is too warm. 🧵 1/n phys.org/news/2025-05...

Birch Glacier Landslide - AntarcticGlaciers.org
The collapse of Birch Glacier and the devastating landslide that impacted the Swiss village of Blatten occurred as a result of supraglacial landslides.

Huge effort to gather mass loss estimate outside ice sheets btw 2000 and 2023 📈
Since 2000, 5% ice volume lost globally (273 gigatonnes/yr) 🌊
Guess who 'won'? 🥇

An ice core suggests that the West Antarctic Ice Sheet lost ice 125,000 years ago, but not to the extent proposed by some scenarios.
