Global Warming Silver Lining? Arctic Could Get Cleaner: Science in the News
Global Warming Silver Lining? Arctic Could Get Cleaner from National Geographic News There may be a bright side to global warming, at least in the Arctic—the changing climate could improve air quality in the polar region, a new study shows. The find is rare good news for the Arctic, which most studies find is warming much more rapidly than the rest of the planet. Currently, air pollutants generally travel from industrially developed regions in the south northward to the Arctic, where pollution contributes to heating up the polar climate. The reason for the potential boost in air quality is increased global rainfall, which many climate models predict will be a widespread result of global warming, said study leader Timothy Garrett, an atmospheric scientist at the University of Utah. http://ow.ly/6G3Uf
