Abstract : In the past ten years, climate change has gained significant attention. Global climate change does not always affect various places in the same way. One important weather factor associated with climate change is rainfall. An appropriate first step in assessing how climate change may impact food security and water availability is to examine patterns in temperature and rainfall. The temperature, precipitation, and changes at several Arunachal Pradesh districts from 2001 to 2021 are examined in this study. We examined fourteen districts using the Mann-Kendall (MK) and Sen's Slope estimator test, which may identify long-term monotonic trends as well as variations in temperature and rainfall. The maximum and lowest temperature data revealed notable upward and decrease patterns, indicating that the region had experienced a change in climate. Nonetheless, there was an increase in rainfall patterns.

Keywords : Climate Change, Temperature, Rainfall, Mann– Kendall Test, Sen’s Slope Estimator, Trend Analysis, Arunachal Pradesh.
