The researchers claimed that the Siachen Glacier reduced to 5.9 km in its longitudinal extent from the time period of 1989 to 2009. This happened because of increasing temperatures. The researchers additionally also believed that presence of humans on Siachen would affect other neighbouring glaciers such as Milan, Janapa, Miyar and Gangotri which are a source to Chenab, Sutlej and Ganges river.
Hindukush, Karakoram and Himalaya actually form the largest mountain chain on this planet. They are also keepers of the third-largest ice reserves only after Polar Regions. The glaciers found in these mountains feed a population of 1.7 billion via seven huge Asian river systems which also include Brahmaputra, Mekong, Yangtze, Ganges and Indus.
Siachen is largest mountain glacier of the world, which is 70 km in length and 5-10 km in width. The satellite pictures revealed that the glacier was shrinking. It is even worse that the satellite images displayed increasing numbers as well as sizes of blue lakes in glacier.
The main cause of Siachen shrinking is construction of the helipads as well as frequent flights of helicopters which loosen packed snows leading to avalanches. Snow scooters also cause the same. Most of the experts believe the fact that saving these glaciers is actually the scientific challenge which needs attention immediately.
