Global climate change is a problem for human well-beings with immediate challenges to physical health, socioeconomic, and psychological well-being. As physical health is being threatened by rising global temperatures, frequent natural disasters, vector-borne diseases, and malnutrition, many countries continue to face socioeconomic challenges due to disruptions to food production, food security, and import revenue. These circumstances have caused damage and loss of homes and infrastructure as well as increased the prevalence of health problems. Furthermore, as global climate conditions worsen and natural disasters become more frequent, individuals experience a decline in mental health and social well-being. This causes a higher prevalence of post-traumatic stress disorder, major depression, and ecoanxiety, as well as an increase in social challenges such as interpersonal violence, environmental displacement, and intergroup conflict over resources. Recently psychologists have begun exploring the motivations for climate action and inaction to design interventions to increase community action. Additionally, there is a growing body of research on interventions targeting individuals who experience poor mental health and social well-being because of climate-related challenges. These interventions include counselling that is therapy-based, community-based, or psychoeducation on climate literacy. This chapter reviews recent and relevant research in climate and behavioural sciences on the psychosocial impacts of climate change.
