KATHMANDU, Nepal — One-third of Himalayan glaciers will melt by the end of the century due to climate change, threatening water sources for 1.9 billion people, even if current efforts to reduce climate change succeed, an assessment warns.

If global efforts to curb climate change fail, the impact could be far worse: a loss of two-thirds of the region’s glaciers by 2100, said the Hindu Kush Himalaya Assessment released Monday by the International Centre for Integrated

Mountain Development.

“Global warming is on track to transform the frigid, glacier-covered mountain peaks of the Hindu Kush Himalayas cutting across eight countries to bare rocks in a little less than a century,” said Philippus Wester of the center, who

led the report.

The five-year study looked at the effects of climate change on a region that cuts across Asia through Afghanistan, Pakistan, India, Nepal, China, Bhutan, Bangladesh and Myanmar. The area, which includes the world’s tallest mountain peaks, has glaciers that feed into river systems including the Indus, Ganges, Yangtze, Irrawaddy and Mekong.

The assessment said that the impact of the melting could range from flooding from the increased runoff to increased air pollution from black carbon and dust deposited on the glaciers.

Saleemul Huq, director of the International Center for Climate Change and Development, an environmental research center in Dhaka, described the findings of the report as “very alarming,” especially for downstream nations such as Bangladesh.

“All the countries affected need to prioritize tackling this upcoming problem before it reaches crisis proportions,” he said in an email. Huq was one of the study’s

external reviewers.
