Mont Blanc, the ‘roof of Europe’, loses more than a metre of height in a year
Peak of French mountain now 4,807 metres high and fluctuates year by year due to changes in Alpine climate
TL;DR
- Mont Blanc's height is now 4,807.47 metres, a decrease of 1.29 metres from 2025.
- The summit's height constantly shifts due to weather affecting snow and ice thickness.
- Since 2001, the summit has shrunk by 3.43 metres from its 2007 high.
- Experts advise against directly linking annual height fluctuations to climate change, differentiating altitude from ice mass.
- While climate breakdown is causing rapid ice melt in the Alps, its direct impact on Mont Blanc's summit altitude above 4,000 metres is not yet clear.
