Overview

• Refuge de la Selle and other high-altitude shelters have installed makeshift pipelines to capture glacial meltwater as their usual reserves dwindle.
• Conditions above 3,200 meters on Mont Blanc are the driest ever recorded, intensifying concerns over late-summer water shortages.
• A dark rock patch on the Bossons Glacier has expanded into a large 'eye,' absorbing extra heat and accelerating localized melt.
• Swiss authorities warn that snow and ice on some 1,400 glaciers melted five to six weeks earlier than normal in 2025, signaling a perilous melt season.
• Alpine temperatures have risen at nearly twice the global average rate, raising fears that French glaciers could vanish almost entirely by 2100 and threaten regional water supplies.
