Swiss Glaciers Lose over 5% of Ice Volume in 2026 as Heat Waves, Low Winter Snow Accelerate Thaw
- On Thursday, the Swiss Glacier Monitoring Network and the Swiss Commission for Cryosphere Observation reported that Swiss glaciers lost 5.5% of their ice volume in 2026, driven by a record-breaking European heatwave.
- A combination of record summer temperatures and insufficient winter snow drove the "enormous" melting, according to GLAMOS director Matthias Huss. The loss remains slightly below the 2022 record of 6% due to more winter snow cover.
- Scientists estimate Swiss glaciers lost around 2.2 trillion liters of water between July and September alone. Switzerland's largest glacier, Aletsch Glacier, suffered its biggest-ever melt this year, while Glacier de Tsanfleuron lost more than four meters of thickness.
- Known as Europe's "water tower," Swiss glaciers feed major rivers including the Rhine and Danube, but accelerated melt threatens to disrupt hydropower production and agricultural water supplies.
- Huss warned that Alpine glaciers have no chance of long-term survival under current conditions, with warming entirely driven by human emissions. "Now we are in this new world, in this future, where glaciers are just melting away," he said.

The volume of ice in the Swiss Alps has reportedly decreased by almost 20 percent in the last five years.
The situation is critical, in 2026 the average thickness of individual glaciers decreased by 2.5–4 meters.
This is a new "catastrophic" year for Swiss glaciers, which experienced their second worst annual balance after 2022, bringing to almost 20% the loss of their volume in five years, according to a study published on Thursday. ...

According to data from the Swiss Ice Survey Network, Swiss glaciers melted at more than twice the rate observed in any other five-year period.
The glaciers in Switzerland lost about 5.5 per cent of their ice during the current year, in the second largest annual loss recorded, as a result of heat waves and falling snow during winter, according to a report by the Swiss Glacier Surveillance Service and the Swiss Academy of Sciences.
