The Global Glacier Casualty List includes one of the last glaciers of the Aragonese Pyrenees in the list that are about to disappear. Lost, missing masses of ice in an irreparable state or in an accelerated process of disappearance.

According to researchers from the Pyrenean Institute of Ecology (IPE-CSIC) who collaborate with it, the loss of ice in Monte Perdido has accelerated dramatically. They also point out that this is a general trend, as the thickness of the snow mass throughout the Pyrenees has decreased by six meters in the last decade, especially in the years 2022 and 2023 that have been the warmest.

The Insitutua denounces that the rising temperatures, the lower accumulation of snow and the increase of extreme heat periods have generated defrosting. If the climate maintained its current trend, by 2035 the Perdido glacier would disappear. But even if the weather conditions were hobbies, it would be almost impossible to recover them.
