Abstract: Climate change is profoundly altering regional climatic patterns, posing significant challenges to environmental management, agriculture, and resource planning. This study examines the decadal variation in key climatic variables viz. precipitation, maximum temperature, and minimum temperature over three decades (1990-2020) in South Tamil Nadu, a region with diverse geography and a climate crucial to its agriculture-driven economy. Using monthly weather data sourced from WorldClim.org and GeoAItool - Google Earth Engine, the study identifies a comprehensive geospatial analysis including spatial and temporal trends in climatic variables during the pre-monsoon (January-May) and monsoon (June-December) seasons across 11 districts in South Tamil Nadu. Results highlight significant variations in temperature and precipitation, underscoring the region's vulnerability to climate change impacts. By offering a detailed interpretation of decadal climate dynamics, this research contributes to strategies for climate adaptation and resilience building. The findings aim to inform regional policy formulation and support sustainable agricultural and environmental planning.
