Climate change may play a big role in affecting the mental health of young people, according to a new report from the American Psychological Association. The report, written in collaboration with the climate advocacy organization ecoAmerica, documents how environmental events linked to climate change — including weather disasters, extreme heat, and poor air quality — can trigger or worsen mental health problems in children and adolescents. Natural disasters can lead to post-traumatic stress disorder in these groups, the report says. Longer-term problems, such as heat, drought, and poor air quality, can increase the risk of anxiety, depression, bipolar disorder, aggression, cognitive impairment, and more. (Giri Viswanathan , CNN).
