Melting Glaciers on the ‘Roof of the World’: What You Need to Know

Recent research has unveiled alarming ice loss in Asia’s Pamir Mountains, raising concerns about the stability of one of the world’s last remaining glacier regions amid global warming.

Historically, glaciers worldwide have experienced retreat due to rising temperatures. However, the “roof of the world” in Central Asia has shown resilience. From the 1970s to the early 21st century, glaciers in the Western Kunlun, Karakoram, and Eastern Pamir Mountains remained stable or slightly expanded.

Fan Yu and researchers from the Chinese Academy of Sciences have closely monitored the three-kilometre-long Kangxiyan Glacier in China’s Xinjiang Uighur Autonomous Region, located at an altitude of 5,350 meters within the eastern Pamir Plateau.

Prior to 2022, the glacier exhibited minor fluctuations but maintained a stable pattern of moderate ice mass loss, sometimes even slightly increasing in volume.

However, a notable shift occurred post-2022, with researchers recording an unprecedented ice loss of 1.5 meters in 2025 alone, representing over four times the average loss from 2011 to 2024.

This record melt at Kangxiyan has been mirrored across other glaciers in the Pamir Plateau, primarily driven by extreme heat. Unlike previous years where high temperatures were limited to short periods, 2025 saw prolonged heat enduring throughout the entire snowmelt season.

The findings suggest that the glaciers in the Pamir-Karakorum region are no longer exceptions to global melting trends. Researchers predict that extreme weather events will likely exacerbate glacier melt in this crucial region.

Sean Eaves and researchers from Victoria University in Wellington, New Zealand, assert that these results correlate with predictions indicating that human-induced climate change heightens the likelihood of severe warming events that contribute to glacier melting. However, they caution against definitive conclusions about future trends at this early stage.

Since the ice mass of the Kangxihe Glacier was only first measured in 2011, the events of 2025 are not extreme when viewed within a broader historical context.
