Human presence at Siachen may also be affecting the neighbouring glaciers of Gangotri, Miyar, Milan and Janapa which feed Ganges, Chenab and Sutlej rivers, the Dawn reported.

According to the study by Dr Ghulam Rasul of the Pakistan Meteorological Department, Himalaya, Karakoram and Hindukush together make the largest mountain chain on earth and they are the custodian of the third largest ice reserves after the Polar Regions.

The glaciers in these mountain ranges feed 1.7 billion people through seven large Asian river systems, including the Indus, Ganges, Brahmaputra, Mekong and Yangtze.
