Severe melting of glaciers despite heavy snowfall at high altitudes
After the extreme circumstances encountered in 2022 and 2023, no relief is in sight for Swiss glaciers. Despite exceptionally large volumes of snow during the winter, a combination of temperatures in July and August that at times reached record levels and dust from the Sahara resulted in a loss of 2.5% of the glacier volume. This was reported by the Swiss Commission for Cryosphere Observation of the Swiss Academy of Sciences on Tuesday.

Dopo due anni di nevicate scarse e di estati molto calde, il permafrost in Svizzera rimane sempre caldo anche nel corso dell’anno idrologico 2023, il suo tenore in ghiaccio continua a diminuire e i ghiacciai rocciosi continuano a muoversi velocemente. Lo dimostrano le ultime misurazioni della rete svizzera di osservazione del permafrost.

One extreme year follows another. Glaciers in Switzerland lost 6% of their volume in 2022. However, 2023 saw 4% destroyed, representing the second largest decline since measurements began. The Swiss Commission for Cryosphere Observation of the Swiss Academy of Sciences reported that a total of 10% of the ice volume disappeared in only two years.

Matthias Huss est le mesureur en chef des glaciers en Suisse. En 2022, il a vécu une année extrême. La fonte de la glace et l’intérêt des médias n’ont jamais été aussi élevés. Les mesures actuelles sont en partie réalisées avec les mêmes méthodes qu’il y a cent ans.
