Glaciers in Asia’s Hindu Kush Himalaya could lose up to 75% of their volume by century’s end due to global warming, causing both dangerous flooding and water shortages for the 240 million people who live in the mountainous region, according to a new report.

A team of international scientists has found that ice loss in the region, home to the famous peaks of Everest and K2, is speeding up. During the 2010s, the glaciers shed ice as much as 65% faster than they had in the preceding decade, according to the assessment by the Kathmandu-based International Center for Integrated Mountain Development (ICIMOD), an intergovernmental scientific authority on the region.

“We’re losing the glaciers, and we’re losing them in 100 years’ time,” said Philippus Wester, an environmental scientist and ICIMOD fellow who was the lead author of the report.

The Hindu Kush Himalaya stretches 3,500 km (2,175 miles) across Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal and Pakistan.

At 1.5 degrees Celsius or 2C of warming above preindustrial temperatures, glaciers across the entire region will lose 30% to 50% of their volume by 2100, the report said.

But where glaciers will melt most depends on location. At 3C of warming — what the world is roughly on track for under current climate policies — glaciers in the Eastern Himalaya, which includes Nepal and Bhutan, will lose up to 75% of their ice. At 4C of warming, that ticks up to 80%.

The full picture

Scientists have struggled to assess how climate change is affecting the Hindu Kush Himalaya. Unlike the European Alps and North America’s Rocky Mountains, the region lacks a long historical record of field measurements that reveal whether glaciers are growing or shrinking.

“There was always some uncertainty in the Himalaya — are they really melting?”, said Wester.

In 2019, the United States declassified spy satellite images of the region’s glaciers dating back to 1970, providing a new scientific baseline.

Further advances in satellite technology in the past five years, alongside bolstered field efforts, have buoyed scientists’ understanding of the changes underway. The report draws on data running through December 2022.

“While the knowledge of the Himalayan glaciers is still not as good as the Alps, it’s now comparable to other regions like the Andes,” said Tobias Bolch, a glaciologist with Graz University of Technology in Austria unaffiliated with the report.

Compared with a 2019 ICIMOD assessment of the region, “there’s a much higher level of confidence now in these findings,” said Wester. “We have a better sense of what the loss will be through to 2100 at different levels of global warming.”

Livelihoods at risk

With this newfound understanding comes grave concern for the people living in the Hindu Kush Himalaya.

The report found water flows in the region’s 12 river basins, including the Ganges, Indus, and Mekong, are likely to peak around mid-century, with consequences for the more than 1.6 billion people who depend on this supply.

"While it may sound like we'll have more water because glaciers are melting at an increased rate ... too frequently it will arise as floods instead of a steady flow," said Wester. Past peak water, supplies will eventually dwindle.

Many high mountain communities use glacial water and snowmelt to irrigate crops. But the timing of when snow falls has become more erratic, and there’s less than there used to be.

“We’ve had ... huge numbers of yak deaths because during summer they go to higher pastures,” said report co-author Amina Maharjan, a senior specialist in livelihoods and migration at ICIMOD. If the snow falls too soon, “the entire area is covered in snow and they don’t have grass to graze”.

People are now moving away from mountain communities to earn income elsewhere, she said.

Melting glaciers also pose a danger to downstream communities. Runoff pools in shallow lakes, held back by rocks and debris. The risk comes when a lake overfills, bursting through its natural barrier and sending a torrent of water rushing down mountain valleys.

Governments are trying to prepare for these changes. China is working to shore up the country’s water supplies. And Pakistan is installing early warning systems for glacial lake outburst floods.

The integrated summer program of Jeddah Season 2025 officially launched under the theme “Jeddah is Different.”

The program combines entertainment, culture, and tourism across several main destinations that include the city’s most iconic landmarks and key facilities.

This launch aligns with the Kingdom’s efforts to realize the objectives of Saudi Vision 2030 by diversifying entertainment offerings and enhancing the quality of life for citizens, residents, and visitors alike, SPA reported.

At Jeddah Waterfront’s “Jeddah Promenade,” the opening night featured dazzling drone shows, roaming performances, and interactive entertainment characters, offering families and visitors a visually engaging experience. Meanwhile, the “Western Coast” event kicked off in the Obhur area, delivering a unique beach experience that runs until October 4.

The event offers a variety of safe, family-friendly activities including a ladies-only beach, water sports, and live artistic performances, creating a complete coastal entertainment experience catering to all age groups.

In parallel, the “Jeddah Shopping Festival,” which runs through August 31, is transforming the city into a vibrant commercial destination. It features hotel and transportation discounts, live shows, weekly giveaways, and promotional activities across major shopping centers.

Jeddah Season reflects a commitment to offering a comprehensive tourism experience that supports the goals of Vision 2030. It contributes to diversifying entertainment options, stimulating investment, enhancing Jeddah’s global standing as a premier tourism destination, and driving economic, cultural, and tourism growth.
