Climate Change Worsens Smog

ozone levels in the eastern half of the U.S. exceed air quality standards set by the U.S. Environmental Protection Agency (EPA), predicts a report published by the Natural Resources Defense Council (NRDC). The study,

Heat Advisory: How Global Warming Causes More Bad Air Days, was prepared by researchers at Johns Hopkins and Columbia Universities, in collaboration with Yale University, SUNY Albany, and the University of Wisconsin at Madison. The study also predicts a 20% drop in the number of summer days with “good” air quality and a doubling of “red alert” air quality days, as defined by EPA.
