Ein legendärer argentinischer Gletscher wird seit einem Jahrhundert seinen bedeutendsten Rückzugsort unterzogen. In der niedrigeren Ablationszone in der Nähe des Gletscherterminus wurde zwischen 2019 und 2024 im Vergleich zum Zeitraum von 2000 bis 2019 ein 16-facher Anstieg der Oberflächenabsenkungsraten beobachtet

An iconic Argentinian glacier, long thought one of the few on Earth to be relatively stable, is now undergoing its “most substantial retreat in the past century,” according to new research.

The Perito Moreno Glacier in the Southern Patagonian Ice Field for decades has been wedged securely in a valley. But it’s started losing contact with the bedrock below, causing it to shed more ice as it inches backwards.

It’s a change, illustrated in dramatic time-lapse photos since 2020, that highlights “the fragile balance of one of the most well-known glaciers worldwide,“ write the authors of the study in the journal Communications Earth & Environment.

They expect it to retreat several more kilometres in the next few years.
