Satellite Confirms Decline in U.S. Coal Pollution
There’s some rare good news on the energy pollution front, confirmed by groundbreaking new use of satellite imagery.
Emissions of sulfur dioxide, the acid rain precursor that ravages respiratory health, have fallen in half since 2005 over what has been one of the most coal-heavy areas of the eastern United States, reported scientists using the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite.
