A Swiss Academy of Sciences panel is reporting a dramatic acceleration of glacier melt in the Alpine country, which has lost 10% of its ice volume in just two years after high summer heat and low snow volumes in winter
for a possible extreme melt this year amid early warning signs about the country’s estimated 1,400 glaciers, a number that is now dwindling.“The acceleration is dramatic, with as much ice being lost in only two years as was the case between 1960 and 1990,” the academy said. “The two extreme consecutive years have led to glacier tongues collapsing and the disappearance of many smaller glaciers.”
All of Switzerland — where the Alps cut a swath through most of the southern and central parts of the country — was affected, though glaciers in the southern and eastern regions melted almost as fast as in 2022’s record thaw. The average loss of ice thickness was up to 3 meters in places such as the Gries Glacier in Valais, the Basòdino Glacier in the southern canton, or region, of Ticino, and the Vadret Pers glacier system in eastern Graubunden.
Snow depths measured in the first half of February were generally higher than in the winters of 1964, 1990 or 2007, which were also characterized by low snowfalls, the team said. But snow levels sank to a new record low in the second half of the month of February, reaching only about 30% of the long-term average.
