Brief communication: 'Multi-hazard-to-health-outcome' (MH2O) pathways: the known, the unknown, and ten most urgent priorities.
Abstract. Climate-driven hazards like heat and flooding have complex impacts on human health. Most research considers the impact of individual hazards (e.g., heatwaves) on discrete health outcomes (e.g., heatstroke). However, climate-driven hazards often precipitate additional hazards with cumulative health impacts, such as the compound effect of drought and heatwaves on the physical and mental health of farming communities. Little is known about ‘multi-hazard-to-health-outcome’ (MH2O) pathways. We engaged multi-sectorial and international stakeholders through the newly established MH2O Working Group and report our co-developed ten most urgent priorities for guiding research, policy and practice towards preparing our global One Community for future uncertainty.

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.
