This would seem to be consistent with the presented data; the bulk of the increase is in the West and Midwest (which I believe picked up a fair amount of the smoke from the fires). The Northeast and South are mostly the same.
The article suggests increases in driving as a contributing factor; but does not explain why that would be concentrated in the West and Midwest, and not the South or Northeast. Likewise with EPA regulation changes: why would they dominate in the West and Midwest? There may be reasons, it's unfortunate the article doesn't explore them.
- huffmsa 7y agoMidwest here, we got some weird cold grey, but not cloudy weather during the 2018 California fires. It was noticable, both visually and in the air quality.
- frankharv 7y agoYes I agree and feel the whole article is skewed by averaging. West Coast and Midwest rose by ~10 percent while East Coast and the South is still falling by almost 1 percent. I wonder how much particulate matter is coming across the Pacific from Asia in addition to the fires causing a raise. I also question how we could have dropped to Zero particulate matter. That seems wrong to me.
