摘要:Deaths from heat waves, hospital evacuations due to floods and wildfires, asthma exacerbations from heatamplified air pollution, drought-related malnutrition emergencies, changing patterns of infectious disease— every year it becomes clearer why pollution and climate change are the greatest threats to health and health systems of our time. Many health benefits are expected if average global temperature is kept closer to 1·5°C than 2°C above preindustrial levels.1 Concerningly, in the latest Intergovernmental Panel on Climate Change (working group 1) Assessment Report only the lowest emissions scenario shows temperatures staying below 1·5°C, and this is only after a brief period of overshoot.2 Globally, plans exist to produce more than double the amount of fossil fuels in 2030 than would be consistent with limiting global surface temperature warming to 1·5°C.3
