Study shows, POK lost around  25% Glaciers.

The area covered by glacial deposits decreased from 15,110 hectares in 2000 to 13,520 hectares in 2010, representing a loss of 1,590 hectares over ten years or an average of 159 hectares per year. The increased rate persisted, with the glacier area further decreasing to 11,350 hectares by 2017. This indicates the melting of 2,170 hectares in just seven years, or an annual melting rate of 310 hectares per year, the speaker concluded.

Between 2000 and 2017, glacier were lost  by 3,760 hectares. On an average, a loss of 220 hectares of glaciers every year since 2000.

"The current pace of glacial retreat raises serious concerns, potentially leading to the disappearance of these vital water resources within the next 51 years," the environmental expert warned.

Remote Sensing and GIS technic are used to study the Glacier Cover on a Landscapes

As per United States Geological Survey, A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information. It uses data that is attached to a unique location. Most of the information we have about our world contains a location reference: Where are USGS streamgages located?

As per United States Geological Survey, Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth.
