Switzerland\u2019s glaciers have accelerated their retreat in the most recent data from September 21, 2026, according to the latest figures from the Glacier Monitoring Switzerland network, or GLAMOS<\/a>.<\/strong> It appears that only 2022 was a worse year for ice loss. However, 2026 could surpass it, as the melting season is far from over. A late-season heat wave has continued to grip Western Europe since the figures were released and remains in place at the time of writing (September 30).<\/span><\/p>\n

Some select glaciers \u2013 probably smaller, lower-elevation ones \u2013 are showing losses nearly five standard deviations below the mean \u2013 a 1 in 3,500,000 scenario assuming historical climatic conditions apply. The largest glaciers, like the Aletsch, are 2.4 standard deviations below the mean \u2013 a 1 in 500 melt year. | Photo: GLAMOS<\/figcaption><\/figure>\n

While low winter snow drives these annual losses in part, it\u2019s summer heat that drives melt significantly below the mean line.<\/strong> This winter was slightly below average in precipitable water, but the glaciers hit \u201cmelt day\u201d around June 29 (where the red line crosses 0 on the chart above), largely due to the month-long heat wave that preceded it. That\u2019s three months earlier than scheduled in a stable glacier environment.<\/span><\/p>\n
