    Scientists may have significantly underestimated a dangerous source of pollution in the atmosphere, new research suggests. A satellite study, published Monday in the journal Nature Geoscience, has revealed nearly 40 previously unreported major sources of sulfur dioxide emissions — a pollutant that can cause multiple harmful health and environmental impacts and even impact the climate in certain ways, typically by temporarily reducing the effects of global warming.
    In their study, researchers from Canada’s environment and climate change department and other institutions in the United States and Canada have described a new method that allows them to identify and map sulfur dioxide sources all over the world — including sources that may not have been previously identified or reported. And they’ve found that anywhere from 7 to 14 million metric tons of sulfur dioxide may be missing from global inventories each year.
    The new method combines satellite data with wind information to more accurately pinpoint pollution sources.
