Short summary
Climate change will increase the frequency of extreme weather events like floods, droughts and storms. These hazards have impacts on human health. Some hazards, like storms, cause additional hazards like flooding. Little is known about the compound effects of multiple hazards on health, or how impacts vary between communities and areas. We present ten urgent research priorities related to the impact of multiple hazards on health to guide future decision-making towards climate resilience.
