As documented across this chapter, there is a large adaptation deficit for health and well-being, with climate change causing avoidable injuries, illnesses, disabilities, diseases and deaths . Implementation of health adaptation has been incremental because of significant constraints, primarily relating to financial and human resources and because of limited research funding on adaptation . Current global investments in health adaptation are insufficient to protect the health of populations and communities  from most climate-sensitive risks, with large variability across and within countries and regions . Climate change adaptation in health is < 1% of international climate finance despite health being a priority sector in 54% of NDCs featuring adaptation .
