Yep. Those of us who saw —and tried to breathe in— the Los Angeles basin in the late 1960’s can attest. As a kid, family went to visit friends in Whittier. We kids headed to park/playground. Usual horsing around for 20 minutes led to stinging throat, eyes, and a ripping headache for all four of us. Quite different today. Current hysteria/activism at over extremely fine particulate matter is, however, over the top, and the returns on the cost of the bureaucrats’ efforts are nil.
