This seminar report summarizes research on factors affecting glacier changes in the Himalayas. It discusses methods used to monitor glaciers such as geodetic, hydrological, optical remote sensing, radar, and laser scanning. Several glaciers in the Himalayan region were analyzed including Gangotri, Dokriani, Chorabari, and Pindari glaciers. Key parameters studied include temperature, precipitation, elevation change, debris cover, and snow line altitude. Observations showed most glaciers retreating due to increasing temperature and precipitation trends. Smaller glaciers showed faster percentage area loss than large glaciers. Factors like elevation, slope, aspect and debris coverage influenced glacier response. While research has
