Title

The current and future impacts of climate change on human health in Indiana

Abstract

Climate change is already being felt on local levels, with historical records from the State of Indiana (USA) revealing warmer winters and more extreme precipitation events. To refine our understanding of climate change impacts on human health, we conducted a state-level assessment of future climate change impacts on human health using outputs from advanced climate model projections for this century. Future projections show a steep increase in extreme heat events, leading to greater potential vulnerability to heat disasters for Indiana communities. Additionally, a 2- to 4-fold increase in days with “uncomfortable night” conditions by the end of the century will strongly impact the cardiopulmonary health of more vulnerable populations (i.e., elderly, those with pre-existing conditions, children, and those with inadequate access to cooling). Continued trends for warmer winters and more flooding suggest a much greater risk for the expansion and virulence of a number of vector-borne diseases, such as Lyme disease, West Nile Virus, and “tropical” diseases for which the mosquito vectors will thrive. Higher temperatures will also drive more frequent and severe harmful algal blooms in lakes and reservoirs, with implications for human and animal health. Food systems will also be impacted, particularly with increased risk of contamination by bacteria and mycotoxins due to elevated heat and humidity.
