Abstract: Older adults have higher mortality risk during climate change. Using data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and the China Meteorological Yearbook, this study employs the Cox proportional hazards model to test the impacts of climate factors and individual socioeconomic characteristics on older adults' mortality risk. The research results indicate that changes in climate factors lead to changes in older adults' mortality risk. Extreme high and low temperatures have a significant negative impact on the mortality risk. Its interaction terms with other climate factors, such as air pressure and humidity, are also significant. Unmarried rural older men have a higher mortality level, while economically advanced older people typically exhibit lower risk. Social security plays an interference or reinforcement interactive role in the impact of different climate factors on the mortality risk of older adults, which can effectively improve their climate adaptability.
