Cooling Effect of Preindustrial Fires on Climate Underestimated
Cornell UniversityA new study, “Reassessment of Pre-Industrial Fire Emissions Strongly Affects Anthropogenic Aerosol Forcing,” by a Cornell University postdoctoral researcher, published in August in Nature Communications, finds that emissions from fire activity were significantly greater in the preindustrial era, which began around 1750, than previously thought. As a result, scientists have underestimated the cooling effect the aerosol particles produced by these fires had on the past climate.
