“The U.S. had seen decades of falling levels of fine particulate matter #pollution, PM2.5, thanks to environmental regulations and cleaner engines, factories and power plants. But #wildfires’ contribution to #AirPollution is increasing again, resulting in flat or rising levels of air pollution in much of the country.” https://newsie.social/@TheConversationUS/111020656608431944
“#Climate models predicted this reality as global temperatures rise. Hotter, drier conditions, coupled with dry grasses and underbrush that accumulated over decades of fire suppression, have made large wildfires more common. Computer simulations of the future in a warming climate show more #smoky days, higher #smoke concentrations, larger burned areas and higher emissions – which further fuel #ClimateChange.”
