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.

What's bad about that job? The US doesn't emit a relatively high per capita greenhouse gases because it hates Mother Earth, but because it is doing valuable activities which happen to emit greenhouse gases in the course of the activity.
I find it remarkable how would-be environmentalists can ignore the vast improvement in US pollution over the past half century and obsess over greenhouse gases. But then again, what would they do if these problems were actually considered fixed? Find a real problem?

Well with Trump and Pruitt removing all the hard won protections id say there is good reason to worry.
