Rapid Himalayan warming fuels deadly flood cascade in Nepal and Tibet

Rapid warming in the Himalayas has intensified a chain of landslides, floods and related hazards that killed over 1,300 people in Nepal and Tibet, a new study reports. The research, carried out by the World Weather Attribution team, links the disaster directly to the climate crisis. Scientists say the region is warming faster than any other major mountain range on the planet. That rapid heat increase has pushed glaciers toward faster melt and destabilised mountain slopes. When glaciers melt quickly, water builds up in lakes that can burst, sending flood waves downstream. The study calls the resulting series of events a "geohazard cascade" that now exceeds what local communities can adapt to. Researchers warn that existing flood defenses and emergency plans are no longer enough under such extreme warming. The report adds that without swift cuts to greenhouse‑gas emissions, similar or worse catastrophes are likely to repeat across the Himalaya. The findings echo warnings from earlier reports by the Guardian, CNN, BBC and Reuters that highlighted climate change as a key factor behind the Nepal‑Tibet floods.
