Neuroscience and climate action: intersecting pathways for brain and planetary health

The climate crisis and the human brain are intricately connected. Climate change impacts neurocognitive health, while climate actions both shape and are shaped by the brain. However, research examining these connections remains scarce. This review highlights how neuroscience can deepen the understanding of the reciprocal relationship between climate action and the brain. First, we discuss how both individual and collective climate action can, directly and indirectly, benefit our brain health, mental health and cognitive functioning and how emphasising this holds the potential of harvesting self-interest as a driving force for change. Second, we explore the role of the brain's emotional and decision-making systems in motivating climate action. We also discuss neuroscience's potential to predict population-level behaviours and aid in the systematic development of interventions. By addressing current knowledge gaps, we identify the next steps for deepening our understanding of the interwoven connections between climate action and the brain.
