I need to read the study because this article is so full of holes. I like how it says that stricter clean air regulations “in China”. “Smaller than PM2.5”. What?…. I’ve heard similar things said by a high profile EPA director in person several years ago. He said that the worsening air in LA was causing the huge increase in childhood asthma there. I pointed out that the air quality there had vastly improved over the past three decades. “Oh.”

I love science. But it’s a lonely interest these days…
