All those crematoriums, industrial furnaces, and huge sulfur dioxide plumes were sending a big message which most ignored. Don't forget that the steel mills were running full bore while the industries needing steel were shut down...
Also, without waste disposal services running, might some of sulfur dioxide plumes be from burning of trash?

there were no trash fires - bio-waste perhaps; even if there was one fire, it would not emit that much sulfur dioxide, day after day week after week, and be visible from space; nor would it be in the center of the city where many crematoriums (running 24/7) are (coincidentally) located.
