Nepal floods: The Himalayas are melting faster

Key Points:

• Himalayan glaciers are melting 65% faster than a decade ago, causing unstable glacial lakes and increasing risks of cascading hazards due to permafrost thaw and slope destabilization, according to new research by Systemiq and partners.
• Despite the growing threat, only about 21 of the estimated 40,000 glaciers in the Himalaya-Karakoram region are closely monitored, creating a significant gap in understanding and managing the rapidly changing landscape.
• The Himalayas supply water that supports roughly 20% of India's GDP, including agriculture, hydropower, and pilgrimage economies, yet mountain states capture only about 5% of this economic value, highlighting the region's critical but underappreciated role.
• Black carbon pollution, primarily from brick kilns in the plains, accounts for about one-third of glacier melt and represents a controllable factor that India and neighboring countries can address to slow glacier loss.
• The report recommends urgent actions including enhanced glacier monitoring, improved disaster preparedness, reduction of black carbon emissions, and a shift in tourism management towards sustainable local benefit to mitigate the mounting risks to millions of lives and livelihoods.
