⛰️ In a new study in @science.org, we project that 39% of the global glacier mass is committed to be lost irrespective of future warming.

However, a lot can still be saved - see title:
“Glacier preservation doubled by limiting warming to 1.5°C versus 2.7°C”

[1/n]

⏰ New study shows ambitious mitigation (1.5°C) saves 2X as much ice globally (53% left) than our current pathway, which will destroy >75% glacier ice once it fully adjusts to a warmer climate

Every fraction of °C counts!

+0.1°C warmer = 2% more glacier mass lost

Grateful to have co-led this GlacierMIP3 study with Harry Zekollari. Shared first authorship makes paper writing much more fun! Big thanks to our core team: Fabien Maussion, Regine Hock, Ben Marzeion & David Rounce — and all other co-authors. This was only possible together with you!

Final study of my PhD is out!

Our multi-model, multi-millennial glacier study shows:
Every 0.1°C less warming preserves ~2% more mountain glacier mass; long-term impacts are much larger than 2100-only projections suggest.

🏔️🌍🌎🌏 New study warns: Even if we only temporarily exceed 1.5 °C, mountain glaciers face irreversible losses lasting centuries. Such an overshoot reduces glacier runoff, specifically in regions where some glaciers regrow.
