Himalayan glaciers could lose 80% of their volume if global warming isn’t controlled

Glaciers are melting at unprecedented rates across the Hindu Kush Himalayan mountain ranges and could lose up to 80% of their volume this century if greenhouse gas emissions aren’t sharply reduced, according to a report. The report warned that flash floods and avalanches would grow more likely in coming years, and that the availability of fresh water could be curtailed for nearly 2 billion people who live downstream of 12 rivers that originate in the mountains.
