At the World Health Assembly in Geneva last week, World Health Organization (WHO) member states adopted a resolution on Climate Change and Health. The Resolution clearly identifies climate change as a major threat to public health, and sets out a framework to build climate-resilient and sustainable health systems. Among various proposed measures were multi-sectoral cooperation, awareness raising on the interdependence between climate change and health, and decarbonization to tackle the root cause of climate change. The adoption demonstrates a political commitment by governments and WHO to scale up climate action as a public health priority to protect people from the growing health impacts of climate change.
