Abstract	Climate change is reshaping hydrological systems worldwide, with river basins among the most vulnerable to its effects. The Ganga River Basin (GRB), one of the world's largest and most densely populated basins, is particularly sensitive to these changes. As a critical freshwater source for agriculture, domestic use, and ecological sustenance, the GRB plays a central role in India’s environmental and socio-economic stability. Long-term precipitation trends in the GRB show vast spatial and temporal changes. While some regions, particularly in the lower basin, show increasing rainfall, others demonstrate declining trends or greater interannual fluctuations. This study utilizes high-resolution climate data from the Climatologies at High Resolution for the Earth’s Land Surface Areas (CHELSA) version 2.1 dataset, covering the period 1979 to 2018. CHELSA provides free access to high-resolution climate data for research and application. Change in precipitation is visible after year 2000 in GRB with maximum change is visible in monsoon season in GRB where it decline in western part of the basin on the other hand there is increase in eastern part of the basin in same period, while there is slight increase in pre-monsoon precipitation in most part of the GRB. The yearly mean is not that change but there is change in seasonal mean with increasing variability during recent years. With the enhancement in the software technologies it is now become a good tool to study this type of climate change in depth and can contribute great knowing the fact how it will going to shape or impact our future generation. Artificial intelligence can do the process of analysing and predicting the extreme events due to climate change with the help of weather forecasting model very well in future as of the AI is still developing.
