Fun-fact. There were deadly smog events even before the 'liberal media' and 'climate change' were even mainstream subjects.
https://en.wikipedia.org/wiki/Great_Smog_of_London"The Great Smog of 1952, sometimes called The Big Smoke ,[1] was a severe air-pollution event that affected the British capital of London in December 1952. A period of cold weather, combined with an anticyclone and windless conditions,
collected airborne pollutants – mostly arising from the use of coal – to form a thick layer of smog over the city. It lasted from Friday, 5 December to Tuesday, 9 December 1952 and then dispersed quickly when the weather changed."
No I think it's a multitude of different polluting agents and chemical waste. I don't believe it all comes from coal.
Such as what? Which other pollutants in specific?
