Huh? Could Cleaner Air Be Worsening Global Warming?
SAN FRANCISCO — It may seem counterintuitive, but cleaner air could actually be exacerbating global warming trends.
The soot and other particles that make up air pollution tend to scatter light back out into space. As countries around the globe have cleaned up their act, there are fewer particles to reflect light, meaning more sunlight is reaching the Earth's surface and warming it, Martin Wild, a researcher at ETH Zurich in Switzerland, said Tuesday (Dec. 15) here at the annual meeting of the American Geophysical Union.
