Pamir Glaciers Rapidly Melting Even Above 5,000 Meters, Tajik Scientists Warn
Tajik scientists have conducted the country’s first direct winter field measurements of snow dynamics on a Pamir glacier since independence, with findings showing a sharp decline in snow reserves and accelerated melting even in high-altitude zones previously considered relatively stable. The expedition took place from May 6-15 on Glacier No. 457, located in the upper basin of the Nukhchashma River, also known as Tokuzbulak, a tributary of the Gunt River. The research was carried out by specialists from the Mountain Societies Research Institute at the University of Central Asia (UCA), together with the Center for Research of Glaciers of Tajikistan’s National Academy of Sciences, as part of the United Nations initiative “Decade of Action for Cryospheric Sciences, 2025-2034.” The scientists’ primary objective was to study the glacier’s winter mass balance by analyzing snow accumulation, density, and distribution across the glacier surface. According to the organizers, these are the first direct winter field measurements of glacier winter snow dynamics conducted in Tajikistan since the country gained independence. The work comes as glacier preservation is receiving growing international attention. The United Nations says rapid glacier melt threatens billions of people, especially those who depend on glaciers for drinking water, agriculture, and energy. Tajikistan’s glaciers are particularly important for Central Asia because they feed rivers that support downstream communities, irrigation, and hydropower. Previous glacier monitoring efforts in Tajikistan were largely limited to summer expeditions and satellite observations. Denis Samyn, senior research fellow and professor of Earth and environmental sciences at UCA, said Central Asia’s glaciers had remained insufficiently studied for decades. “Now, with support from the state and international partners, the region is gradually developing its own school of cryospheric research and a new generation of specialists,” he said. Scientists expressed particular concern over the latest monitoring results. UCA researcher Hofiz Navruzshoev said Glacier No. 457 has been monitored annually since 2020, although previous studies primarily focused on summer melting. “The 2025 observations revealed a critical situation: the glacier’s thickness decreased by more than one meter, which is a very significant indicator,” he said. According to Navruzshoev, seasonal snow cover in the glacier’s accumulation zone at elevations above 5,100 meters has virtually disappeared over the past five years. This means the glacier is no longer replenishing lost ice even in its upper accumulation areas, which traditionally served as long-term snow storage zones. That trend is significant because the accumulation zone is the part of a glacier where winter snow normally survives long enough to compact into ice. If that zone stops gaining snow, the glacier can lose mass even before lower-elevation melting is taken into account. The expedition operated under difficult high-altitude conditions, with researchers working at elevations of around 5,000 meters amid rapidly changing weather, snowfall, strong winds, and near-zero visibility. During the mission, scientists dug five snow pits at elevations ranging from 4,790 to 5,012 meters, measured snow depth and density, and collected data on glacier snow reserves. The findings add to wider scientific concern about the Pamirs. The Times of...
