Abstract: Climate change is negatively impacting not only physical health but also mental health, as individuals and communities cope with climate stresses and shocks, as well as threats to their and future generations’ welfare. By 2050, climate change will place immense strain on global healthcare systems, causing 14.5 million deaths and $12.5 trillion in economic losses. Evidence and action on the intersection of climate change and health is growing rapidly but progress is hindered by several critical challenges. From a vicious to a virtuous cycle, the opportunity for action should not yet be missed. In this talk, we will discuss how climate policy and action can be an opportunity multiplier for creating the conditions that foster good health such as more connected and equal societies, clean air, and access to green spaces, while good health and psychological resilience can be an enabler of sustained climate action.
