The disaster also damaged at least six major hydropower plants and altered river channels more than 100 km downstream.

How Is Climate Change Affecting Himalayan Flooding?

While experts caution against describing climate change as the sole trigger, they say rising temperatures and melting glaciers played a critical role . "Climate change is generating conditions that can destabilise high-mountain rock and ice," said Simon Cox, chief scientist at Earth Sciences New Zealand . The UN warned in 2023 that global warming caused Nepal's snow-capped mountains to lose close to one-third of their ice cover in just over 30 years, with glaciers melting 65% faster in the prior decade . Floods, landslides, avalanches, and droughts are increasing across the Hindu Kush mountain range.

What Is Being Done to Rescue Flood Victims in Nepal?
