OBJECTIVE: The purpose of this scoping review is to identify and describe the existing literature on the impact of the overarching awareness and concerns of climate change on children's mental health and well-being. INTRODUCTION: Children are widely acknowledged as being disproportionately at risk to the effects of climate change, yet research overlooks the impact that climate change has on their mental health. Children's overarching awareness of climate change, and its global effects, may influence their mental health and well-being. INCLUSION CRITERIA: This review will include all research that addresses school-aged children's (aged 3-19) mental-health issues stemming from an awareness of climate change. It will not include research that examines direct impacts of climate change on children's mental health, such as trauma from a specific climate-related event. METHODS: Searches will be conducted across eight research databases (Cochrane Database of Systematic Reviews, CINAHL, Embase, GreenFILE, PubMed, PsycINFO, Web of Science, and Scopus) and three unpublished/gray literature databases (ProQuest Dissertations and Theses, GreyLit.org, and OpenGrey). Data will be extracted for author(s), year of publication, country of origin, purpose, population, methodology, concepts of interest, outcomes, and key findings relating to the scoping review objectives. Findings will be presented as a narrative summary.
