Climate change perception and mental health: the public health perspective

Abstract Climate change is increasingly recognized as a critical environmental stressor with significant psychological impacts. Despite consolidated evidence describing the impact of various aspects of climate change on numerous physical and mental health outcomes, a novel and burgeoning area of research is now assessing the association between climate change perception/awareness and health. In fact, the increasing awareness of climate change and its impacts on natural and human systems is not only a matter of environmental concern but also of significant psychological importance. Awareness of climate change involves understanding its causes, foreseeing its long-term global and local impacts, and recognizing the limited window available for effective mitigation and adaptation. This level of awareness, while necessary for proactive behavior, has been linked to various psychological responses, including chronic stress, anxiety, and feelings of helplessness and despair, collectively referred to as ‘eco-anxiety.’ The association between climate change awareness and mental health is complex and mediated by various individual and social factors. As the reality of climate change becomes more integrated into the public consciousness, it is imperative to address the accompanying psychological impacts. In this presentation, the main issues related to climate change perception/awareness and mental health will be discussed through the lens of public health.
