"After years of decline, a spike in air pollution may have taken the lives of almost 10,000 additional Americans over two years," reports Eric Roston.

"Following a 24% drop between 2009 and 2016, particulate matter air pollution in the U.S. increased 5.5% in 2017 and 2018, according to a new analysis of Environmental Protection Agency data by two Carnegie Mellon economists."

Researchers "found evidence for three potential sources of the pollution rebound: increased economic activity, virulent wildfires and a smaller number of EPA enforcement actions."

The National Bureau of Economic Research published the working paper this week.
