The Himalayas, known as the “water towers of Asia,” are under immense pressure from climate change. A new report highlights that by 2100, these glaciers could lose up to 75% of their ice. This would drastically impact water availability for over a billion people across India, Nepal, and Bangladesh. The melting glaciers are also expected to cause more frequent flooding, landslides, and changes to regional ecosystems. Immediate efforts are needed to address greenhouse gas emissions to prevent this catastrophic outcome.
