Himalayan Snow Cover Vanishing by 2100
14 Mar
Summary
- Nearly 68% of Himalayan snow cover may vanish by century's end.
- The region warms nearly twice the global average rate.
- Millions downstream face water security threats from melting glaciers.
A peer-reviewed study indicates a critical threat to the Himalaya's snow cover, projecting a potential loss of nearly 68% by the end of the century if current warming trends persist. This research highlights alarming climate-driven changes across the Hindu Kush-Himalaya region, known as Asia's "Water Tower."
The region has experienced warming at a rate of 0.2-0.3°C per decade between 1980 and 2020, significantly faster than the global average. This accelerated melting is causing glaciers to shrink and snow cover to diminish, with implications for downstream water availability.
Expanded glacial lakes and increased GLOF risks are also noted, alongside a rise in avalanche activity and thawing permafrost. These changes destabilize mountain slopes, increasing landslide hazards. The study emphasizes the urgent need for enhanced monitoring and cooperation to manage these escalating risks.
