In 2016, ACP published a paper in Annals of Internal Medicine, outlining the negative consequences of climate change on public and individual health and offering five specific recommendations to mitigate such threats. Potential health effects of climate change include higher rates of respiratory and heat-related illnesses, increased prevalence of diseases passed by insects, water-borne diseases, food and water insecurity and malnutrition and behavioral health problems, according to ACP.
