Climate change has adversely affected physical health of people globally  and mental health of people in the assessed regions . Climate change impacts on health are mediated through natural and human systems, including economic and social conditions and disruptions . In all regions extreme heat events have resulted in human mortality and morbidity . The occurrence of climate-related food-borne and water-borne diseases has increased . The incidence of vector-borne diseases has increased from range expansion and/or increased reproduction of disease vectors . Animal and human diseases, including zoonoses, are emerging in new areas . Water and food-borne disease risks have increased regionally from climate-sensitive aquatic pathogens, including Vibrio spp. , and from toxic substances from harmful freshwater cyanobacteria . Although diarrheal diseases have decreased globally, higher temperatures, increased rain and flooding have increased the occurrence of diarrheal diseases, including cholera  and other gastrointestinal infections . In assessed regions, some mental health challenges are associated with increasing temperatures , trauma from weather and climate extreme events , and loss of livelihoods and culture . Increased exposure to wildfire smoke, atmospheric dust, and aeroallergens have been associated with climate-sensitive cardiovascular and respiratory distress . Health services have been disrupted by extreme events such as floods .
