More Evidence Identifies China as The Source of Mysterious Ozone-Destroying Emissions
For years, a mystery puzzled environmental scientists. The world had banned the use of many ozone-depleting compounds in 2010. So why were global emission levels [DOI: 10.1038/s41586-018-0106-2] [DX] still so high?
The picture started to clear up in June. That's when The New York Times published an investigation into the issue. China, the paper claimed, was to blame for these mystery emissions. Now it turns out the paper was probably right to point a finger.
In a paper [open, DOI: 10.1029/2018GL079500] [DX] published recently in the journal Geophysical Research Letters, an international team of researchers confirms that eastern China is the source of at least half of the 40,000 tonnes of carbon tetrachloride emissions currently entering the atmosphere each year. They figured this out using a combination of ground-based and airborne atmospheric concentration data from near the Korean peninsula.

Just went looking for an older reference on acid rain and found that one from The Christian Science Monitor. There are plenty more, but as noted, this paper was highly respected for straight reporting back in the '80s.
Anyway, the point was that coal burning plants in the midwest USA were causing acid rain in the North East and it was to the point that it was damaging forests and many other things. Pollution is not as localized as the earlier poster claimed.
