What happened

The summer of 2026 saw an unprecedented wave of landslides in the French Alps, especially around Mont Blanc, driven by extreme heat and thawing permafrost.

Why it matters

Long considered the safest time of year for mountaineering, summer has in recent years become a high-risk season.

Common ground

In the Alps, 2026 already holds a worrying record: 450 rockfalls in the Mont Blanc massif alone since the start of the year.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
