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.

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.

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.

Speaking from UNEP HQ in Nairobi, ICCI’s AMI Chief Science Advisor Dr. James Kirkham will kick off with a presentation on the latest cryosphere science.

4/ Emissions cuts? Temperature limits? 🧊 As @iccinet.bsky.social says, we cannot negotiate with the melting point of ice.
