Scientists have announced the loss of almost 25% of the volume of Swiss glaciers in 10 years.

According to the Swiss Glacier Monitoring Network (GLAMOS), glaciers in the country's mountains have lost a quarter of their volume over the past 10 years. This was reported on October 1 by France24.

It is noted that the measurements were carried out at 20 reference sites, and their results were distributed to 1,400 glaciers in the Swiss mountains. The melting of ice in 2025 continues to be "colossal" and is approaching a record in 2022, GLAMOS warns. The winter was snowy, and June and August were hot, as a result of which the glaciers lost 3% of their volume. For comparison, this figure was higher in 2022, 2023 and 2003.

According to the study, glaciers decreased by 24% from 2015 to 2025, while in 1990-2000 this figure was only 10%. Since the 1970s, 1.1 thousand glaciers have disappeared in Switzerland, and over the past 25 years their volume has decreased by 30 cubic meters. km, and the area increased by 30%, to 755 square kilometers.

"For about the last 20 years, all glaciers in Switzerland have been losing ice, and the rate of this loss is increasing," said Matthias Huss, head of GLAMOS.

Scientists warn that if action is not taken, Swiss glaciers may almost disappear by the end of the century. Huss noted that it is impossible to stop the melting, but it can be slowed down, but this requires global coordination of actions.

"If carbon dioxide emissions are reduced to zero within 30 years <...> we could still save about one—third of the Swiss glaciers," he explained.

The loss of glaciers can lead not only to problems with water resources, but also to destabilize mountain systems, Huss added.

The World Meteorological Organization (WMO)— the UN's meteorological body, reported in March that record levels of high temperatures in 2024 accelerated the melting of glaciers and sea ice. This has led to rising sea levels and brought the world closer to a key warming threshold. It clarifies that other factors could have influenced the global temperature increase last year, including changes in the solar cycle, a powerful volcanic eruption and a decrease in the amount of cooling aerosols.
