The Pamir Mountains in Central Asia cover an area of about 120,000 km², of which about one tenth is glaciated. They lie at the junction of the Tien Shan and Karakoram ranges, and exhibit little ice mass change over the past 20 years, in contrast with most other glaciers in Asia and globally. But in the medium term, climate change also threatens this ice, which supplies water to the Amu Darya basin. This important mountain water tower has been shown to be particularly vulnerable to future climate changes.
In the SPI Flagship Initiative, more than 30 Swiss researchers will investigate the mystery of this region’s anomalous ice, for which few measurements have been available since the collapse of the Soviet Union. In a total of six sub-projects, the scientists will investigate changes to the snow, glaciers and permafrost, their consequences for river discharge and ecology, as well as natural hazards. Other research will disentangle the history of Soviet glacier investigations in the region, providing an important backdrop for contemporary questions. A high-elevation ice core will document the past climate of the region, while meteorological stations will record the current conditions.
These on-site studies over the next four years will provide crucial data for modelling the future of the ice masses and the water flowing from them. "Because of the looming end of the Pamir-Karakoram Anomaly, this represents a timely and urgent task," says WSL co-study leader Francesca Pellicciotti.
Note to the media: The official launch event of the PAMIR flagship initiative will take place in March. We will inform the media in a timely manner.
