I'm hoping this is a significantly sized piece of the puzzle in the proof against the 'us puny humans can't affect something as large as the earth's atmosphere' climate denial argument. Since the lockdowns the horizon where I live has no brown haze smeared over, and it's not even a significantly sized city (population ~1.5 million), but the lack of haze is noticeable. The presence of the brown smear haze was actually one of the things that made real scale of the effect humanity has on the quality and content of the air that enters our lungs.
