Swiss glaciers suffer 'disastrous' year of ice loss, threatening water supplies

What the report says

Swiss glaciers have recorded a near-record year of ice loss, according to new data reported by BBC World News, with scientists saying more than 5% of the country’s remaining glacier ice has disappeared over the past 12 months. The report says intense summer heatwaves, combined with a winter and spring that left glaciers with less protective snow than usual, accelerated melting across the Alps. Researchers described the pace of loss as extraordinary and said some high-elevation sites ended the summer with no snow cover at all.

The BBC says the findings come from Glacier Monitoring Switzerland and reflect a wider climate trend in which Alpine glaciers are shrinking faster than many experts previously considered possible. Scientists quoted in the report said the development is alarming but no longer surprising in a warming climate, driven largely by greenhouse gas emissions. They noted that darker bare ice absorbs more heat, which can speed further melt once snow cover is gone.

The article says the loss matters well beyond the glaciers themselves. Meltwater helps support farming, hydropower generation and some transport routes during dry periods, but researchers warn that this short-term benefit comes at the cost of depleting long-term ice reserves. The report also links glacier retreat to greater risks of unstable slopes, landslides and flash flooding in some mountainous areas.

The BBC adds that although many Alpine glaciers may eventually disappear if warming continues, sharper cuts in emissions could still help preserve ice in other regions such as the Himalayas and polar areas.
