Swiss Glaciers Melting at Alarming Rate Due to Heatwaves
2 Jul
Summary
- Early heatwaves erased snow from Swiss glaciers a month sooner than normal.
- Exposed ice on glaciers could melt in extraordinary volumes in coming months.
- Glaciers supply vital water for drinking, farming, and energy across Europe.
Europe's recent heat waves have caused the snow atop Switzerland's glaciers to disappear far earlier than usual, a worrying development for the region's water security. By June 29, the snow and ice levels had receded to pre-winter levels, a month sooner than typically observed. This rapid melting exposes the glaciers' ice, which is now projected to vanish in significant volumes throughout the summer.
Glaciologists express deep concern, noting that conditions usually seen in August are present now. This accelerated melting is critical as the Alps' glaciers are a vital source of water for drinking, agriculture, and hydropower across Europe. The loss of snow cover means the underlying ice begins to melt, diminishing the glacier's overall volume and impacting future water availability. Scientists warn that water resources in Europe could become erratic within the next 10 to 20 years.
The situation is exacerbated by record-high temperatures across several European nations, attributed by climate scientists to human-caused global warming. Measurements on glaciers like the Rhône have shown thinning of ice by a meter in just 10 days during June. This trend, where glaciers lose 1-4% of their ice annually, is intensifying in hotter years.
