Rising temperatures could to lead to the loss of thousands of glaciers per year, with up to ~4,000 vanishing annually under high emissions. 1.5°C could halve this loss 🧵 @landervt.bsky.social @harryzeko.bsky.social @matthias-huss.bsky.social @davidrounce.bsky.social @lilianschuster.bsky.social

Over 45,000 glaciers in the western US and Canada will shrink by 70% by 2100 even if global temperature rise is limited to 1.5°C. Their loss rises to 90% under 2.7°C. In central Europe, about 87% of today’s 3,000 glaciers will disappear under 1.5°C, but they almost completely vanish under 2.7°C.

Globally: Glacier loss under 1.5°C is projected to peak around 2040, maxing out at ~2,000 glaciers lost per year. Peak glacier loss under 4.0°C would culminate in the mid-2050s at ~4,000 glaciers per year, equivalent to losing the entire glacier population of the European Alps in just one year.

Limiting warming to 1.5°C could more than double the number of glaciers surviving by 2100 compared with 2.7°C, and prevent the near-complete loss expected under 4.0°C warming. News coverage: www.theguardian.com/environment/... Full paper: www.nature.com/articles/s41...
