A recent flash flood in Nepal, which resulted in over 1400 lives lost and 6000 missing, was triggered by the collapse of a high-altitude glacier near Langtang Lirung peak. An estimated 142 million cubic meters of ice and rocks dislodged, causing a seismic event and subsequent natural dams that failed, unleashing devastating floods.
Researchers attribute this tragedy to a combination of factors, including climate change and current development methods in the Himalayas. Global warming is weakening the mountains by melting glaciers and corroding moraine slopes. This is compounded by an increase in the frequency and intensity of extreme weather events, leading to more frequent flood and landslide catastrophes.
The article also points to the impact of human development, such as hydroelectric projects that dam rivers and extensive road construction without adequate slope management, as exacerbating these natural vulnerabilities. The author argues that a fundamental shift in mindset is needed, moving away from the belief that humans can control nature, to one that respects its limits.
