In May 2025, the small Swiss village of Blatten faced a major disaster. A large section of the Birch glacier gave way. Ice, rocks, mud, and water rushed down the mountain. This buried most of the village. Around 300 people live in Blatten. They had to evacuate quickly. A search was launched for a missing 64-year-old man. Drones with thermal cameras were used. But the search continues.

The collapse of the glacier is linked to global warming. Permafrost is thawing. This makes the ground unstable. Rocks and ice move more easily. Matthias Huss, a glacier expert, noted that climate change is causing rapid shifts. Temperatures are rising. Water seeps between rocks. This weakens them and speeds up erosion.

The landslide created a natural dam. It blocked the River Lonza. A lake is forming behind it. Water levels are rising fast. Up to a million cubic meters of water could accumulate daily. Authorities declared a state of emergency. They fear the dam could break. This would cause severe flooding.

Nearby villages like Gampel and Steg were evacuated. An artificial dam downstream was emptied. This is to prepare for the backflow. But the debris makes it hard to intervene directly. The military is ready with pumps and heavy equipment. Helicopters are assessing the damage. Livestock are being airlifted to safety.

Residents are in shock. Martin Henzen, a local, said they were prepared for some disaster. But not one this big. Jonas Jeitziner, from a nearby village, described the community's profound shock. Recovery efforts have just begun.

This event highlights the growing risks of climate change. Glaciers are melting. Permafrost is thawing. These changes bring new dangers. Communities must adapt. They need better preparation and support.
