The adverse effects of air pollution and climate change on human health have already been a major global environmental issue, and the challenges in China are even more severe. In this issue, titled "Air Pollution Climate, Change and Health" , we present a series of articles that reviewed and analyzed the impact of air pollution and climate change on human health systematically, and propose recommendations for the next phase of research.
