Glacier thinning in Himalayas threatens water security for downstream communities.
Glaciers in the Garhwal Himalaya, India are thinning and slowing down due to climate warming. A study analyzed 205 glaciers and found that they are losing ice at different rates. Gangotri Glacier thinned the most, while others with debris on top melted less. The glaciers are moving slower, especially in lower areas, which could lead to more hazards for nearby communities.
