Swiss glaciers lose over 5 % of ice volume in 2026 as heat waves , low winter snow accelerate thaw

Swiss glaciers experienced a 5.5% reduction in ice volume during 2026, marking the second-largest annual decline on record. Experts attribute this accelerated thaw to a combination of persistent heat waves and insufficient winter snowfall across the Alpine region.

Switzerland hosts the highest concentration of glaciers in the Alps, making these findings a significant indicator of regional environmental shifts. The data highlights the ongoing impact of climate conditions on glacial stability, with experts noting that the current trajectory poses a severe challenge to the long-term survival of these ice formations.
