Medical professionals are on the front lines taking care of patients experiencing the direct impacts of air pollution and climate change. From higher ozone and particle pollution levels due to increased heat and wildfires—to threats from severe storms and the spread of vector-borne diseases—the science is clear; climate change poses one of the greatest threats to lung health.
