Switzerland has misplaced 10% of its glaciers in simply two years, analysis reveals, after excessive summer time warmth and low winter snowfall.
The nation misplaced as a lot ice within the 24 months because it did within the three many years earlier than 1990, researchers mentioned, describing the ice soften as “catastrophic”.
Switzerland – residence to probably the most glaciers of any nation in Europe – has seen 4% of its whole glacier quantity disappear in 2023, the second-biggest decline in a single yr on high of a document 6% drop in 2022.
The group at Glacier Monitoring Switzerland (GLAMOS) mentioned the “massive ice loss” stemmed from a winter with very low volumes of snow – which falls on high of glaciers and protects them from publicity to direct daylight – and excessive summer time temperatures.
All of Switzerland – the place the Alps lower a swathe by a lot of the southern and central elements of the nation – was affected, although glaciers within the southern and japanese areas melted virtually as quick as in 2022’s document thaw.
In some locations, GLAMOS needed to stop monitoring as a result of soften.
Images posted on social media by Matthias Huss, who leads GLAMOS, throughout information assortment journeys in current weeks confirmed new lakes forming subsequent to glacier tongues, in addition to streams of soften water working by ice caves, and naked rock poking out from thinning ice.
“This year was very problematic for glaciers because there was really little snow in winter, and the summer was very warm,” he mentioned.
“The combination of these two factors is the worst that can happen to glaciers.”
More than half of the glaciers within the Alps are in Switzerland the place temperatures are rising by round twice the worldwide common on account of local weather change.
In some locations, our bodies misplaced way back have been recovered as ice sheets have shrunk.
“Melting of several metres was measured in southern Valais (region) and the Engadin valley at a level above 3,200 metres (10,500ft), an altitude at which glaciers had until recently preserved their equilibrium,” the GLAMOS group mentioned.

The common lack of ice thickness was as much as three metres (10ft) in locations such because the Gries Glacier in Valais, the Basodino Glacier within the southern canton, or area, of Ticino, and the Vadret Pers glacier system in japanese Graubunden.
The state of affairs in some elements of the central Bernese Oberland and the Valais was much less dramatic – resembling for the Aletsch Glacier in Valais and Plaine Morte Glacier within the canton of Bern, as a result of they loved extra winter snowfall.
But even in such areas, “a loss of over two metres of the average ice thickness is extremely high,” the group mentioned.
