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.
