Climate Change Linked to Nepal Floods

Recent analysis by World Weather Attribution (WWA) reveals that human-induced climate change intensified the severe rainfall in Nepal from September 26 to 28, contributing to floods that resulted in over 240 fatalities. The study indicates that the rainfall was approximately 10% more intense due to climate change, with a 70% increased likelihood of such extreme events occurring in today's warmer climate. Rapid urbanization and deforestation have further exacerbated the impacts of flooding in the Kathmandu Valley, where built-up areas have increased significantly, disrupting natural water flow and drainage systems. Eyewitness accounts confirm that the flooding was unprecedented, with certain weather stations recording over 320 mm of rain—equivalent to nearly half of London's annual rainfall. The findings stress the urgent need for Nepal to restrict development in flood-prone urban areas and enhance early warning systems to mitigate future disasters. Experts warn that without a transition to renewable energy sources, the frequency and intensity of such destructive floods are likely to increase.
