The 2025 Blatten disaster in the Swiss Alps followed exceptional warming and highlights the vulnerability of people and heritage in glaciated landscapes

On May 28, 2025, the village of Blatten and nearby settlements in Switzerland's Lötschen valley were buried under 20 million cubic meters of rock and ice, marking a catastrophic event linked to unprecedented climate warming. This disaster occurred during the warmest decade recorded since at least 742 CE, underscoring the severe vulnerability of both people and heritage in glaciated landscapes. The study highlights the urgent need for adaptive strategies to mitigate future risks in such environments.
