Abstract

Sulfate emitted from the burning of fossil fuels is thought to limit global warming by acting as a shield that reflects solar radiation back into space. But recent measurements of atmospheric particles over the U.S. east coast indicate that carbon particles, which absorb radiation, far outnumber the more reflective sulfates. Theoretically, such a particle mixture would increase global warming.
