Swiss glaciers suffer 'disastrous' year of ice loss, threatening water supplies
But scientists say long-term glacier thinning and the thawing of frozen ground likely raised the risks.The notable finding from this latest report is not so much that Swiss glaciers are shrinking - which is to be expected in our warming climate, driven primarily by fossil fuel emissions - but the sheer pace of melting. Until recently, glaciologists in the Alps considered 2% of ice lost in a single year to be "extreme". Scientists estimate that Swiss glaciers released 2.2 trillion litres of meltwater between July and September.Although that helped to ease water shortages this summer, it has rapidly diminished the frozen supply.

Swiss glaciers suffer 'disastrous' year of ice loss, threatening water suppliesImage source, L.HösliImage caption, The front of Morteratsch Glacier in south-east Switzerland, which has been attacked by warm air and waterByMark PoyntingClimate reporterPublished1 minute agoSwiss glaciers have suffered a near-record loss of ice in 2026, new data shows, as intense summer heatwaves take their toll on Alpine peaks.More than 5% of the country's remaining glacier ice has disappeared in the last 12 months, which scientists say is "extraordinary".They warn that such rapid melting is no longer a surprise given the pace of climate change, but it could threaten water supplies for farming, hydropower and transport in the decades ahead.The loss of glacier ice can also destabilise mountain slopes and…
