Swiss glaciers expose decades-old mountaineer remains as Alpine ice loss accelerates

Alpine glaciers have lost 39 percent of their surface area since 2000, with Italian experts warning of rapid and unprecedented changes. Vanda Bonardo, the Alpine representative of Italian environmental group Legambiente, said glaciers "appear still and immovable," yet melting has exposed bedrock and widened crevasses, making trails dangerous . The World Glacier Monitoring Service reported an average annual loss of 273 billion tons of ice globally since 2000, rising to 408 billion tons in 2025 .

In Switzerland, the retreat of glaciers has exposed the remains of two Belgian mountaineers missing since 1992 near the Weissmies mountain in the Valais region. A hiker discovered human remains near the Trift glacier south of Lucerne last month, and DNA tests confirmed the identities . Such discoveries have grown more frequent as Switzerland’s glaciers melt at an accelerating rate, with the country losing 4 percent of its glacier volume in 2023 after a 6 percent loss the prior year.

The village of Kandersteg, home to 1,300 people, lies beneath the unstable Spitze Stei rock formation, which could trigger a landslide twice the size of the one that buried parts of Blatten in May 2025. Scientists attribute the instability to rising temperatures melting glaciers and thawing permafrost, which weakens mountain slopes. Authorities monitor the formation continuously and say a collapse would provide at least 24 hours of warning. Residents like Brigitte Jüni and Rudolf Isler acknowledge the risk but remain calm, linking it to broader climate shifts .

In Brienz, a Swiss village once threatened by a potential rockfall, authorities are planning a study on future development after receiving 42 relocation requests. The local government has allocated 82.5 million Swiss francs to support residents who choose to leave, with the canton and federal government covering most costs. Two buildings have already been destroyed by landslides, and 13 more are slated for demolition. The outgoing mayor, Daniel Albertin, will commission the study with ETH Zurich before leaving office in 2027 .

Switzerland’s population reached over 9.1 million at the end of 2025, a 0.8 percent increase from the previous year, according to the Federal Statistical Office. Growth has slowed from 1.7 percent in 2023 and 1.0 percent in 2024, with 76,100 additional residents in 2025. Immigration accounted for 92 percent of the increase, while the remaining 8 percent came from a natural surplus. For the first time, the number of people aged 65 or older (1,810,600) exceeded those under 20 (1,804,500) .
