' Catastrophic': Swiss glaciers lose fifth of mass in five years

Switzerland's glaciers, which are disproportionately impacted by climate change, have lost nearly 20 percent of their mass in five years, experts said Thursday, with 2026 registering the second-biggest melt on record.

Swiss glaciers saw 5.5 percent of their volume melt away this year, the Glacier Monitoring in Switzerland (GLAMOS) network found in a new study, published after a record hot summer preceded by a winter with little snowfall.

"The glaciers this year have lost enormous quantities of ice," said GLAMOS chief Matthias Huss, describing 2026 as "a catastrophic year". Between 2022 and 2026, the melt rate at Switzerland's glaciers was "more than twice as high as in any previously monitored five-year period", the GLAMOS report said, noting an ice volume loss of almost 20 percent since 2021.
