Nepal disaster: Climate change and infrastructure risks blamed for 1,300 deaths

Scientific investigations into the devastating disaster in Nepal, which claimed at least 1,300 lives and left thousands missing, point to a combination of climate change and infrastructure vulnerabilities. Researchers from institutions including Imperial College London and the World Weather Attribution (WWA) found that a massive rock and ice wall covering approximately 2 square kilometers collapsed in a valley, releasing immense energy. The friction from the sliding mass likely caused rapid ice melt, creating massive volumes of water that swept through the valleys.

While climate change is a primary driver—noting that the Hindu Kush-Himalaya region is warming three times faster than the global average—experts also highlight systemic failures in land use. Critics argue that essential infrastructure, such as hydropower plants and roads, was often built in high-risk flood zones. These decisions frequently prioritized profit through concessions while failing to account for cumulative regional risks, leaving local communities to bear the brunt of the destruction when the systems failed.
