The American Psychological Association and ecoAmerica are pleased to offer this report, bringing forward recent and respected research on the impacts of climate change on children and youth, and guidance for response. This is a follow-on to our 2021 report, Mental Health and Our Changing Climate: Impacts, Inequities, Responses. Since that report appeared, concerns about the mental health impacts of climate change have grown among scientists, health professionals, policymakers, and the public, and the effects on children and youth are more pronounced.
