What is the global evidence on climate-related and nature-based mental health interventions?Although psychosocial interventions are currently recommended in treatment guidelines worldwide to reduce the adverse mental health effects of climatic impact drivers, this umbrella review found the credibility of the evidence basis for this recommendation to be very low. Nature-based interventions were associated with favorable mental health outcomes generally but evidence specifically for climatic impact drivers was lacking.Guidelines and policies for mental health interventions in the context of climate change need to be largely informed by global evidence from contexts other than climate change.
