Climate change that is deviation or shift in average of long—term weather conditions is a global concern that needs to be dealt at regional level. The present study investigates the phenomenon of climate change in Himachal Pradesh which is situated in the Himalayan region that is known for its fragile ecosystem and sensitivity towards small climatic shifts. The research includes analysing long term trends and variability in temperature and precipitation patterns. It utilizes gridded data of temperature and precipitation for the period of over fifty years ranging from 1971 to 2024. The study explores decadal changes in maximum, minimum and average temperatures as well as precipitation distribution across the districts of the state. Statistical tools such as IDW interpolation using ArcGIS and Z-score method using Excel are employed to detect trend and anomalies in climate variables. The results indicate that there has been a gradual rise in temperature and rainfall extremes in the earlier decades whereas accelerated rise in both the phenomena has taken place after the year 2000. These findings highlighted that increase these irregularities have affected environment and human livelihood of the region. The findings of the study highlight the growing vulnerability of mountainous ecosystems to climate change and underscore the need for adaptive strategies and sustainable resource management in Himachal Pradesh.
