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.

    I took "science" and not econ, both in school and in college, so let me clear some things up.  90% of pollution produced in China would not in any way reach the US - it is simply too far.  Pollution is heavy, it does not go high up in a jetstream and traverse vast oceans.  Things that break down Ozone do go up and destroy ozone - mostly over the poles.  Again - not over the US.

    One of the things you learn in "science" is how big the earth is.  You're complaining that someone in a different state farts and it smells in your house.  No, we don't really have "1 atmosphere" when it comes to pollution.  We have many localized bodies of air, where the heavy pollution particles are generated and settle in the immediate area.  It's why you don't want a coal plant near your house, but the one in the neighboring state is fine.

    Dumping stuff into the water does travel over oceans to detectable levels.  Not to levels that actually do anything, but detectable with precision equipment.  Your body is not precision equipment.

    Global warming - that's not caused by pollution.  Another things we learned in "science" - in the 5th grade, which you should really give another try before going for your GED.  Pollution is not greenhouse gasses.  Actual pollution reduces global warming by blocking sunlight.  Literally thousands of reputable studies - one of the more prominent ones done on airplane exhaust particles on 9/11.

    To quote someone - "knowledge is power" - get some.  You seem like one of those anti-vaxxer people who read headlines on the puffington post and your facebook and youtube feed, and repeat them.  You seem to be some kind of a hipster who reads physics books that don't have any math in them and pretends he knows things.  Please stop talking - this is annoying to the adults in the room.

    As far as the politics, it would take someone really dumb to think a paid Russian troll is posting to soylent.  Someone like you.  Someone who does not know how to spell "high school" so he takes a typo from the comment to which he is replying and repeats the misspelling.  Someone who does not speak English well.  Again, 5th grade seems to be where you stopped with the schoolbooks and started with sensationalist headlines with sources for bored soccermoms for your education.

    Not so fast -- https://www.csmonitor.com/1984/0621/062135.html [csmonitor.com]

    From 1984 (seriously, not a reference to Orwell's book):

    In the absence of a national policy to control acid rain in the United States , the New England governors are considering battling Midwest polluters in court. At the annual conference of the New England Governors and the Eastern Canadian Premiers here Monday, Gov. Richard A. Snelling (R) of Vermont said, ''In the absence of a federal law, we can seek damages in court.''

    The chiefs of state say forests and lakes in the Northeast are being choked by acid rain. They claim that air pollution, produced primarily by the smokestack industries of the Midwest, is being deposited across the Northeast when it rains.

    I remember when this was a big deal, in NY state our crushed-limestone driveway used to bubble when it rained.

      The Christian Science Monitor. Seriously - why are you on this site? This is literally not the forum for you. This is a tiny community. If you are thinking to agitate or piss off people, all you are going to do here is have a small handfull of people laugh at you. Very small. Would your idiot trolling not be more appropriate somewhere where you have an audience >20?

      I didn't click the link or read your post.

        I don't know about the present, but the CSM has long had a reputation for accurate and remarkably unbiased journalism. It has nothing beyond the name to do with the Christian Science religion.

        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.

        Oh, and I'm not new here, I'm logged in with a user number in the 3 digits, but normally post as AC.

        The Christian Science Monitor is an excellent newspaper for objective news. The Christian Science stuff is restricted to one regular article which is clearly labeled as such.

          Yes, idiots who read the CSM think it's an excellent newspaper for objective news. The Christian religion is an excellent guideline for your saving your soul. "How to rape little boys" is an excellent newspaper. Forget the title - they only have one article on what lube to use on the pink asshole of the little one - the rest is objective science on how CFCs cause global warming.

          Now the rest of us who read and study actual science - the science with "math and shit" - do not get our science from the CSM. This is why we know that most pollution does not cause global warming and comprehend the basic concept of a particle in the atmosphere blocking sunlight from reaching the earth causing a reduction in temperature. The most famous of such studies was as noted when all the planes were grounded on 9/11, and there was a clear finding that pollution from airplanes reduces global warming. Now back to raping little boys - do you have any sons and where do they practice baseball (asking for a friend)?

    Do... do you truly not understand, generally, how CFCs interact with the atmosphere and environment?

      Idiot: "Have you ever heard about climate change buddy?"
      Me: "Things that break down Ozone do go up and destroy ozone - mostly over the poles. Again - not over the US."

      Do you... Truly not understand that CFCs don't cause global warming and the pollution actually reduces it because particles block and reflect sunlight?
