Parents and grandparents face unprecedented challenges in supporting their children to survive, cope with and adapt to the impacts of climate change while simultaneously preparing them for the greater negative impacts predicted in the future. This chapter draws on multidisciplinary research in parenting science, child and youth development, and disasters to guide parents in varying contexts. We first discuss how parents and carers can help young people cope with the direct exposure to both sudden and gradual climate disasters and flow-on effects that exacerbate social inequalities. We then discuss how parents can help children manage the emotions that knowledge of climate change can engender, explore parents’ vital role in fostering children’s sense of agency and hope, and highlight ways that parents can support young people’s active engagement. We end by stressing that parents and others with responsibility for raising the next generations should take action at local to national levels to drive the urgent changes needed to prevent climate catastrophe.
