Description: This report is targeted to actuaries that are interested in identifying the adverse human health outcomes resulting from anthropogenic climate change. This is accomplished by providing a detailed framework to evaluate the impact of extreme heat on human health and identify the role that anthropogenic climate change has on extreme heat events. Although this document is designed around extreme heat, the concepts can be expanded to other climate-related events. As the primary focus of actuarial research is to promote human health and minimize the preventable economic burden, this document also provides recommendations to mitigate against excess heat related illness (HRI) due to extreme heat.
