Perito Moreno glacier in Argentina is experiencing a likely irreversible retreat, having lost 1.92 sq km of ice cover over the last seven years, along with a thickness reduction of up to 8 metres annually. For decades, it resisted global glacial retreat trends, maintaining a balance between accumulation and melting. However, since 2018, a noticeable decline in its mass has been recorded. The glacier's stability is eroding, evidenced by increasing calving events and a shift that began in 2022, raising concerns among scientists and local guides.
The Perito Moreno glacier has undergone a significant and potentially irreversible retreat, losing 1.92 sq km of ice in just seven years.
Calving events at Perito Moreno are becoming louder, more frequent, and larger, indicating an alarming change in glacier dynamics as it continues to thin.
