Climate change poses risks to human health through shifting weather patterns, increases in the frequency and intensity of heat waves and other extreme weather events, rising sea levels, and ocean acidification, among other environmental effects. Robust models that project the future health risks of climate change are needed to inform adaptation efforts, reduce adverse health effects, and to help to inform national and international discussions about climate policies–but so far, the development of such models has been slow. Health risk modelers face challenges such as inherent uncertainty about the links between climate-change events and health outcomes, and the variability and complexity of human health and disease. To explore new approaches to modeling the human health risks of climate change, the Standing Committee on Emerging Science for Environmental Health Decisions held a workshop in November 2014. This report summarizes the discussions and presentations of the workshop.
