More than 2 million deaths worldwide are linked with man-made air pollution each year, according to new findings that also show climate change has contributed only minimally to air pollution–related deaths since the preindustrial age.

Using simulation models and long-term data from the American Cancer Society, researchers found that about 470 000 people die annually of causes related to man-made increases in ozone. Another 2.1 million deaths are linked with man-made increases in fine particulate matter—tiny particles suspended in the air that can penetrate deep into the lungs, causing cancer and respiratory disease.
