Swiss glaciers lose more than 5% of ice volume in 2026 amid record heat

Switzerland's glaciers lost more than 5% of their ice volume in 2026, according to multiple outlets including the Associated Press, NPR, Reuters, The Straits Times and Phys.org. The Washington Times put the figure slightly higher, at 5.5%, calling it the second-biggest percentage drop on record. Outlets attributed the loss to heat waves and low winter snowfall during the year.

Reuters and The Straits Times reported that the ice loss followed a record-breaking European heatwave, with The Straits Times datelining its report from Les Diablerets, Switzerland, on October 1. Phys.org gave the most detailed physical measurements, reporting that glacier thickness decreased by an average of 2.5 to 4 meters (8 to 13 feet) this year, with some glacier tongues losing up to 10 meters (33 feet) of ice. Phys.org noted that while 2026's melt rates did not quite reach the record levels set in 2022, the loss was still substantial, and said the research was published in the journal GLAMOS—Glacier Monitoring Switzerland.

Arab News reported that Switzerland's glaciers have lost nearly 20% of their mass over the past five years due to climate change, describing 2026 as one of the largest melts on record for the country's glaciers and using the word 'catastrophic' in its headline. BBC News and BBC Sport both described the year as a 'disastrous' one for the glaciers in identical headlines, and BBC News added that scientists say such rapid melting is no longer surprising given the pace of climate change.

The Daily Mail reported that 2026 was a 'devastating year' for Switzerland's glaciers, citing scientists from ETH Zurich who warned that several glaciers have been lost forever, a specific claim not detailed by other outlets. NPR reported that the ice loss threatens water supplies, ecosystems and communities across Europe, a framing echoed by the BBC headlines, which also linked the melt to threats to water supplies.

How the coverage differed

Left-leaning outlets, represented by the Associated Press and NPR, emphasized the broader consequences of the melt, with NPR specifically stating that the loss threatens water supplies, ecosystems and communities across Europe. Center-leaning outlets produced the largest volume of coverage and varied in their framing: the BBC used the word 'disastrous' and tied the melt explicitly to water supply threats and to scientists' views that such rapid melting is now expected given climate change; Arab News focused on the five-year, nearly 20% cumulative mass loss and used the word 'catastrophic'; The Straits Times and Reuters shared an identical headline emphasizing the link to a record-breaking heatwave and included the Les Diablerets dateline; and Phys.org was alone among all outlets in providing precise thickness-loss measurements in meters and feet, comparing 2026 to the 2022 record, and naming GLAMOS as the publishing body for the research.

Right-leaning outlets diverged from the rest on the headline figure: The Washington Times reported a 5.5% loss, higher than the 'more than 5%' cited elsewhere, and was the only outlet to call it the second-biggest percentage drop on record. The Daily Mail took a distinct angle by citing ETH Zurich scientists and warning that several individual glaciers have been lost forever entirely, a detail no other outlet reported. Neither right-leaning outlet included the five-year, 20% cumulative figure reported by Arab News, nor the specific thickness measurements reported by Phys.org.

Overall, center-leaning outlets provided the greatest number and variety of reports, ranging from the BBC's water-supply framing to Phys.org's technical detail, while left-leaning coverage was comparatively brief and right-leaning coverage was split between a slightly higher statistical claim and a narrower focus on permanently lost glaciers.

What is still unclear

The sources do not specify which or how many individual glaciers the Daily Mail's cited ETH Zurich scientists say have been lost forever, nor do they reconcile why The Washington Times reported a 5.5% loss while other outlets reported a figure of 'more than 5%' without a precise number. It also remains unclear from the supplied material how the five-year nearly-20% cumulative loss figure cited by Arab News relates precisely to the single-year 2026 figures reported elsewhere.
