The Karakoram anomaly:
There is wealth of evidence that indicates that, in contrast to other glacier regions worldwide, the glacier mass balances in the Karakoram are partially balanced or even slightly positive. The available observations also show a larger regional extent of this anomaly, which also covers the western Kunlun Shan and the eastern Pamir. The Karakoram, in particular the central area west of Baltoro Glacier as far as the Hunza Valley and in the north as far as the Shimshal and Shaksgam Valleys, shows more positive mass balances. This different glacier behaviour, dating back at least to 1970, has been attributed to a regional decrease of summer temperatures and an increase in precipitation that persists until today. Changes in land use, which have a significant influence on evaporation, probably play an additional role in the evolution of these climatic parameters. What is also remarkable, is the strong concentration of glacier surges, especially in the Karakoram. However, no conclusive connection to climatic development has been found yet. In the future, it is assumed that the consequences of climate change will not stop at these regions between Pamir and Kunlun Shan and that the glaciers also will show negative mass balances in the medium term, although perhaps less negative than in the neighbouring areas.
