Swiss glaciers lose 5% of ice volume in 2026 amid extreme heat

Swiss glaciers glacier retreat climate change Alpine melting GLAMOS

Swiss glaciers experienced catastrophic melting in 2026, losing more than 5% of their ice volume in a single year. This follows a period of extreme heatwaves and low winter snowfall. According to reports from the Swiss Glacier Monitoring Network (GLAMOS) and the Swiss Academy of Sciences, the total volume of Swiss glaciers has decreased by nearly 20% since 2021.

Individual glaciers saw significant reductions in thickness, with averages dropping between 2.5 and 4 meters. In some areas, glacier tongues lost up to 10 meters of ice. The Aletsch Glacier, the largest in the Alps, lost six meters of ice since the start of the summer. Small glaciers, such as Bella Tola and Griessfirn, have completely disappeared.

Scientists noted that the zero-degree isotherm remained above 4,000 meters for 76 days during the summer, more than double the average. Between July and September 2026 alone, glaciers lost an estimated 2.2 trillion liters of water. Experts warn that Alpine glaciers have no long-term chance of survival under current climatic conditions.
