Why this matters

Nepal’s steep topography and heavy monsoon seasons make it highly susceptible to glacial lake outburst floods and landslides. Accelerating climate-driven glacier melt is increasing both the frequency and severity of these events, threatening downstream communities and cross-border infrastructure. The disaster underscores the urgent need for improved early warning systems and regional disaster preparedness.
