Switzerland’s glaciers lost 5.5% of their ice in 2026, a record pace that matches the fastest decline ever measured in the country. The finding comes from Switzerland’s glacier monitoring network, GLAMOS, led by Matthias Huss, who spends each summer measuring the nation’s ice fields.
The decline follows a global pattern: glaciers worldwide have been shrinking faster in recent years, and scientists link that acceleration directly to global warming. In 2022, Switzerland recorded a record 6% loss in a single year. This year’s total, 5.5%, fell just below that mark, but the difference came from winter snow rather than a slower melt.
Huss’s Summer Observations
Every summer, Huss goes up into the mountains to take measurements of the nation’s ice fields. This time around, when he came back to the same glaciers, he found that much of the ice had vanished.
“They are completely devoid of ice,” he said. “It’s a moon landscape that is dry and dead. There are some little remnants, some ice blocks still lying around and melting there on the hot rocks.”
Elsewhere, mountain vegetation is moving into regions that were once buried under glaciers many meters thick. According to the report, the ice loss in 2026 stands at 5.5%, and the figure is only slightly below 2022’s record because a little more snow sat on top of the ice during winter.
The Rhône and Aletsch Hit Record Losses
Individual glaciers lost record amounts of ice, and the report documents this, including for Switzerland’s water towers’s biggest: the Rhône and Aletsch. These glaciers are often called Europe’.
They store winter snow and release it gently as it melts over the spring and summer. That meltwater fills Europe’s key waterways, like the Rhine and the Danube. The water is key to Europe’s food supply, and much more.
“It’s the food supply, it’s the transportation chains,” says Huss.
This summer, with river levels falling, freight transport on both the Rhine and the Danube was brought to a halt. River water that normally cools nuclear power stations ran low, forcing several such plants to be shut down temporarily.
Why Drought Could Be Existential
If the melting keeps going, things will only get worse. Europe’s rivers had water this summer, but it didn’t come from seasonal snowmelt; instead, it came from the glaciers themselves melting.
The departure of the glaciers — with 1,200 smaller glaciers vanishing in the last 50 years — leaves Europe’s farmers vulnerable to drought. Without these water towers, there is no steady spring flow of meltwater; instead, there is a sudden release of stored ice.
Landslides and Floods Follow the Ice
Frozen ground and ice fields act as a binding agent that holds mountain slopes together. Should that binding agent fail, the danger of slides and flooding rises.
A glacier collapsed last year in the Swiss village of Blatten, sending the mountain’s flank crashing down with it and obliterating 300 homes. The avalanche of ice, rock and mud is believed to have covered the village to a depth of around 9 million cubic meters.
The instability was under watch, and the population of Blatten was removed from the site before the landslide struck. A full year on, they remain in temporary quarters, with no certainty whether they will ever be able to go back home.
This summer, floods swept across Nepal’s border with Tibet after a glacier collapsed, claiming at least 1,400 lives.
Climate Change as Catalyst
While Matthias Huss avoids drawing a direct line between climate change and these kinds of disasters, he notes that mountain regions have long carried danger.
“It’s a bit more complicated than just saying it’s warm and the glaciers are disappearing, so the mountains are falling apart and causing disasters like this,” he explains.
But he adds that climate change can be the catalyst for such natural disasters. “Combined with this heat, with the disappearance of the ice, with the warming of permafrost, climate change can be a triggering factor. That can just be the last bit that is missing to trigger such events.”
Warning Signs From the Ice
Huss has spent years watching the glaciers, and he no longer tolerates those who say climate change does not exist. He argues that what is happening to the glaciers should serve as a warning sign.
“Look at them, it’s not a hoax. The evidence is clear, and it’s been clear for decades. And I think many people have understood that it’s time to act now.”
The Century Ahead
If nothing changes, Europe’s cherished alpine scenery could transform into something entirely different within a few decades. The glacier monitoring unit forecasts that all the glaciers will vanish by the end of this century if planetary temperatures continue to rise at their present pace.
That 5.5% defeat in 2026 is not a one-off event. It is part of a pattern, and the pattern is headed in one specific way. The real issue is whether anyone steps forward before that course becomes fixed.
Europe’s glaciers are melting away, and with them goes the continent’s water supply, farmland, and mountain stability. The signs of trouble are visible for all to see. What remains unknown is whether anyone is paying attention.
Key Numbers
- 5.5% ice loss in 2026, a new record
- 6% loss in 2022, the previous record
- 1,200 smaller glaciers disappeared in the last 50 years
The numbers add up fast.
