This is a diagram entitled ‘Effects of climate change on human health’. The diagram comprises two concentric circles surrounded by eight segments. The inner circle contains four elements, the outer circle has eight elements. The inner circle has four sectors labelled: rising temperatures, more extreme weather, rising sea levels, and increasing CO2 levels, along with symbols representing sun, rain, waves and wind. The eight elements of the outer circle are: extreme heat, severe weather, air pollution, changes in vector ecology, increasing allergens, water quality impacts, water and food supply impacts, environmental degradation. The eight sectors outside the circles are, respectively: heat-related illness and death, cardiovascular failure; injuries, fatalities, mental health impacts; asthma, cardiovascular disease; malaria, dengue, encephalitis, hantavirus, rift valley fever, lyme disease, chikungunya, West Nile virus; respiratory allergies, asthma; cholera, cryptosporidiosis, campylobacter, leptospirosis, harmful algal blooms; malnutrition, diarrheal disease; forced migration, civil conflict, mental health impacts.
