Pyrenees Glaciers Vanish: Aneto Splits, Declared Stagnant Ice
25 Dec, 2025
Summary
- Pyrenees glaciers lost over a meter in thickness during the 2024-2025 hydrological year.
- Aneto, the highest peak, has shrunk to under 30 hectares and split into three parts.
- Nearly 40 Pyrenean glaciers have disappeared in the 21st century alone.
Glaciers across the Pyrenees Mountains are vanishing at an alarming rate, signaling severe and potentially irreversible damage due to rising global temperatures.
Recent data from the 2024-2025 hydrological year reveals an average loss of over a meter in glacial thickness. Aneto, the highest peak, has shrunk to less than 30 hectares from over 135 hectares in 1981 and is now classified as stagnant ice, raising concerns about its survival.
In this new millennium alone, the Pyrenees have lost almost 40 glaciers, with only 14 remaining. This rapid fragmentation accelerates melting and exposes more ice to the sun. The implications are far-reaching, contributing to sea-level rise, coastal erosion, and extreme weather events.
