Cutting greenhouse gas emissions should improve air quality and thereby save millions of people’s lives by the end of the century, new simulations find.

Burning fossil fuels emits both climate-warming gases and other air pollutants such as particulate matter. Greenhouse gases also contribute to the formation of ground-level ozone, the main component of smog. Because particulate matter and ozone can cause heart and lung disease, researchers think that reducing greenhouse gases would improve pub...
