From PRINCETON UNIVERSITY and the “excessive EPA regulations caused massive exports of US industry to Asia and all I got was this lousy smog” department.

PRINCETON, N.J. — An influx of pollution from Asia in the western United States and more frequent heat waves in the eastern U.S. are responsible for the persistence of smog in these regions over the past quarter century despite laws curtailing the emission of smog-forming chemicals from tailpipes and factories.

The study, led by researchers at Princeton University and the National Oceanic and Atmospheric Administration’s Geophysical Fluid Dynamics Laboratory (GFDL), highlights the importance of maintaining domestic emission controls on motor vehicles, power plants and other industries at a time when pollution is increasingly global.
