Swiss glaciers lose 5.5% of their ice volume in 2025/26
GLAMOS reports the second-worst year after 2022, driven by little winter snow and intense summer heat.
Swiss glaciers lost 5.5% of their ice volume in the 2025/26 monitoring year, according to Glacier Monitoring Switzerland (GLAMOS). The national result ranks second-worst after 2022. Little winter snow and intense summer heat drove the losses. Almost a fifth of the ice has disappeared since 2021. The monitoring year covers October 2025 to September 2026, rather than calendar 2026. Sources: GLAMOS annual mass-balance report and Associated Press reporting.
