[ExI] Recent Increases in Air Pollution: Evidence and Implications for Mortality

[John Clark]

To my mind fine particulate matter is a far more important air pollutant
than greenhouse gasses that you hear so much about because it is a much
more immediate problem. Fortunately fixing that problem is vastly easier
than fixing the greenhouse problem, nevertheless the news on that front has
not been encouraging. In the USA after decreasing by 24.2% from 2009 to
2016 there was a sudden increase in fine particulate matter of 5.5% from
2016 to 2018. In 2018 this increase is estimated to have caused 9,700
additional premature deaths in the USA alone. Can anybody think of a change
in the political climate around 2016 that may have caused this increase?
