Mont Blanc, Western Europe's highest mountain, lost more than a meter of height in a single year, according to surveyors who released their findings on Wednesday. The peak now stands at 4,807.47 metres above sea level, down 1.29 metres from 2025.
The mountain's height fluctuates annually due to shifts in Alpine climate conditions. Heat, wind, and precipitation alter the thickness of snow and ice covering the summit, causing the recorded elevation to change year to year. Scientists measure the peak's actual rock height at approximately 4,792 metres, but the surveyed height includes the ice and snow layer on top.
Last month's expedition recorded a height 1.88 metres greater than 2023, when Mont Blanc reached its lowest levels in recent memory. The variation demonstrates how climate change affects Alpine geology in real time. The survey team tracks these changes through regular expeditions to document how the mountain responds to warming temperatures and shifting precipitation patterns across the region.
Mont Blanc straddles the French-Italian border and holds the title of Europe's highest peak. The mountain's shrinking ice cap reflects broader trends affecting Alpine glaciers across the continent as temperatures rise.
