ABSTRACT
Climate variability has increasingly become an important factor influencing human health outcomes, particularly in climatically diverse regions such as Karnataka. This study examines geographical evidence of climate variability and its impact on health using secondary quantitative data from government sources including the Indian Meteorological Department, Karnataka State Natural Disaster Monitoring Centre, and public health reports. The analysis focuses on trends in temperature and rainfall variability, agroclimatic regional differences, and selected climate-sensitive health
indicators such as vector-borne diseases and heat stress vulnerability. Findings indicate rising temperature patterns, irregular rainfall distribution, and increasing climate-related health risks across districts. The study highlights significant spatial variation where coastal and high-rainfall zones exhibit higher risks of vector-borne diseases, while dry northern regions face heat-related health challenges. The results emphasize the importance of adopting geographically differentiated health strategies and integrating climate data into public health planning. The paper contributes to
multidisciplinary discussions linking geography, environmental studies, and public health, and suggests that climate-resilient policy frameworks are essential for minimizing future health risks associated with climatic fluctuations in Karnataka.
