A devastating flash flood in Nepal that killed more than 1,400 people and left thousands missing has sparked criticism regarding the allocation of international climate funds. While climate change may have been a contributing factor, experts argue that the disaster underscores a failure to prioritize essential life-saving infrastructure, such as early warning systems.
The incident occurred in late August when an ice-and-rock avalanche tore through northern Nepal’s Trishuli Valley. The disaster resulted in over 1,400 deaths and 5,000 missing, with recovery costs estimated at nearly $5 billion, a significant portion of Nepal's economy. UN climate chief Simon Stiell and environmentalist Bill McKibben pointed to climate change as exacerbating such tragedies.
However, the World Weather Attribution group noted that human-caused warming raised Himalayan summer temperatures by approximately 2.7°F above preindustrial averages, calling climate change a "destabilizing factor acting on a pre-existing geological predisposition, rather than the fundamental cause" of the avalanche. A comprehensive study of snow avalanches in high-mountain Asia since 1990 found no long-term trend across 85% of the region.
Critics contend that even if emissions reductions were fully realized, they would not have prevented the recent catastrophe. The primary need, according to the report, was an effective warning system to alert residents in the path of the flood. Many areas had warning times of 40 minutes or more but received no alerts, leading to significant loss of life. In Bidur, a school principal managed to save approximately 900 students through word-of-mouth communication just minutes before the flood arrived.
Nepal's own assessment of the damage highlights the need for improved monitoring, repairs to hydrological stations, and a new system of sirens and text alerts along its rivers, with an estimated initial cost of $2.3 million. Despite substantial climate aid directed to Nepal, little has been invested in immediate safety measures. From 2020 to 2024, over $3 billion in international development money committed to Nepal for climate-related projects was spread across various initiatives.
For instance, German aid allocated $6.7 million towards solar panels to reduce CO₂ emissions, an amount triple the cost of a warning system. A World Bank disaster-resilience program, initially intended to improve flood warnings, shifted its focus to droughts, wildfires, heat waves, and building codes. The Green Climate Fund approved $27.4 million in 2020 for flood and landslide resilience in the Trishuli River basin, but this funding was directed towards irrigation, farmer education, and ecotourism, with no allocation for sirens or alerts.
A $50 million project for sensors, sirens, and backup communications, which had been in the pipeline for seven years, was only approved in 2025, too late to help the victims. This project is not scheduled for completion until 2033.
Comparatively, the World Meteorological Organization estimates that an investment of $800 million in early warning systems in developing countries could prevent $3 billion to $16 billion in annual losses. Bangladesh has significantly reduced cyclone-related deaths since 2007 through improved forecasts, shelters, and drills.
Worldwide, deaths from climate-related disasters have fallen by over 97% in a century, largely attributed to increased wealth and preparedness rather than solely emission cuts. Economic growth is seen as a comprehensive adaptation strategy. While Nepal has made strides in poverty reduction, its per capita GDP remains low, hindering its ability to invest in robust infrastructure like better bridges, carefully sited roads, and functional sensor systems.
The author suggests that international climate summits should prioritize funding for critical infrastructure like warning systems that directly save lives, rather than focusing solely on emissions reductions, and allow countries like Nepal the space to pursue economic growth that enhances their overall resilience.
