Swiss Glaciers Facing Drastic Loss From Heatwave: Expert
Glacier researcher Matthias Huss said the date would be the second-earliest on record as an early heatwave rapidly drains winter reserves.
Swiss glaciers are expected to reach "glacier loss day" on Monday, June 29, marking the second-earliest date on record, according to GLAMOS. By then, all snow and ice accumulated during winter will have melted.
An ongoing European heatwave, combined with poor winter snowfall and Saharan dust, has accelerated the melting. GLAMOS network chief Matthias Huss described the situation as a "combination of bad circumstances" driving significant ice loss.
At the Rhone Glacier, researchers observed one metre of ice melted in just 10 days. Huss called the rapid depletion "very impressive," attributing it directly to sustained high temperatures.
Alpine glaciers face a "very bad state," threatening water supplies for major rivers including the Rhine and Rhone. The early tipping point typically occurring in August suggests long-term instability for the region's water resources.
This year's melt rate is "surprisingly similar" to 2022, which set Alpine records. If current warming trends persist, Switzerland will be left with only "some little remnants of ice" by 2100.
The European heatwave that has also hit Switzerland could see Swiss glaciers lose a huge amount of ice, with the snow and ice that accumulated during last winter expected to melt completely by Monday, the Guardian reports. This also means that this year will mark the second-earliest time ever for the turning point when the snow and ice accumulated during the winter are completely gone and the glacier begins to lose net mass. From then on, until …
