Swiss Glaciers Suffer Second-Worst Ice Loss on Record
Extreme heat and reduced snowfall led to a significant decrease in glacial volume in 2026.
Swiss glaciers experienced their second-largest ice loss on record in 2026, losing 5.5% of their total volume. This dramatic reduction is attributed to persistent heat waves throughout the summer and a lack of substantial snowfall during the preceding winter.
The extent of ice loss this year ranks only behind the record losses observed in 2022, a year that saw exceptionally high temperatures and minimal snow cover. The data highlights the ongoing and severe impact of climate change on the Alps.
Scientists monitoring the glaciers have expressed concern over the accelerating rate of melting, which has far-reaching consequences for water resources, ecosystems, and the tourism industry in the region. The loss of glacial ice contributes to rising sea levels and alters regional hydrological cycles.
