The Youngest Minds in a Warming World: A Review of Climate Change and Child and Adolescent Mental Health

Climate change poses a growing threat to the mental health of children and adolescents. This narrative review synthesizes global, interdisciplinary research on the psychological impacts of climate disruption during critical developmental stages, with attention to marginalized populations. We explore three key pathways of harm: direct exposure to environmental disasters, chronic disruption of ecological and social systems, and existential distress such as eco-anxiety. Drawing on eco-social theory and developmental psychopathology, the review highlights how these impacts are shaped by age, geography, identity, and systemic inequities. It identifies both risk and protective factors, emphasizing the importance of caregiving relationships, cultural practices, education, and youth climate engagement. While activism can foster resilience and purpose, it may also incur emotional burdens that require clinical and policy attention. We argue that child and adolescent mental health must be recognized as central to climate justice and adaptation, and we offer urgent recommendations for integrated action across sectors.
