Every glacier gets its own death date
A new map tracks not just melting ice, but the year each individual glacier on Earth disappears for good.
In brief
A new map tracks not just melting ice, but the year each individual glacier on Earth disappears for good. Regional mass-loss numbers hide the real story: thousands of named, local glaciers have a projected year they cease to exist, and warming decides which year. Originally reported by Glacierextinction.
Ice loss, one glacier at a time
Climate reporting usually counts glacier loss as regional mass and area totals. That framing erases the fate of each individual glacier, including the small ones.
“every glacier, no matter how small, can matter”
Glaciers are more than water
Beyond feeding rivers and raising sea levels, glaciers carry cultural, ecological and social weight, tied to the communities living beneath them.
“glaciers hold important cultural, ecological, and societal value”
When is a glacier dead
Two tests define extinction. Area falling under 0.01 square kilometres, or volume dropping below 1% of where it started, leaving only a scrap of ice.
Three models, four futures
GloGEM, OGGM and PyGEM each project volume and area paths, run across multiple climate models and warming scenarios of +1.5, +2.0, +2.7 and +4.0 degrees.
A median year, not a promise
All the trajectories are pooled into a median extinction year per glacier, with 25% and 75% probability bounds. The map shows a range, not a single certain date.
The peak arrives mid-century
The underlying paper, published in Nature Climate Change in 2026, puts peak glacier extinction in the middle of this century. Outlines come from the Randolph Glacier Inventory.

The one thing
Regional mass-loss numbers hide the real story: thousands of named, local glaciers have a projected year they cease to exist, and warming decides which year.
