Future temperature-related mortality in Latin American cities under climate change and population scenarios.

ABSTRACT:

Background

In Latin America, climate change, urbanization, and an aging population are intensifying health risks from extreme temperatures. To accurately assess future temperature-related mortality impacts, evidence that integrates key demographic factors-such as the dynamics of population age composition, mortality rates, and population size-is essential.

Methods

We projected the impact of nonoptimal temperatures on all-age and age-specific mortality during 2045-2054 for 326 cities in Latin America. Our analysis combined city-level daily mortality counts, gridded temperature data, downscaled and bias-corrected temperature simulations, and demographic data. We projected temperature-mortality impacts under two climate change scenarios while also considering changing populatio
