By Chris Buckley, The New York Times. [https://www.nytimes.com/2018/11/03/climate/china-ozone-cfcs.html] For GSS Ozone chapter 8. Excerpt: BEIJING — An environmental group says it has new evidence showing that China is behind the resurgence of a banned industrial gas that not only destroys the planet’s protective ozone layer but also contributes to global warming. The gas, trichlorofluoromethane, or CFC-11, is supposed to be phased out worldwide under the Montreal Protocol, the global agreement to protect the ozone layer. In May, however, scientists published research showing that CFC-11 levels in the atmosphere had begun falling more slowly. Their findings suggested significant new emissions of the gas, most likely from East Asia. Evidence then uncovered by The New York Times and the Environmental Investigation Agency pointed to rogue factories in China as a likely major source. Now, the E.I.A. has prepared a report that it says bolsters the finding that Chinese factories are behind the return of CFC-11. ...Chinese officials have said they have already acted vigorously to close rogue chemical makers. They have also asserted that the CFC-11 emissions in question are too large to be solely from those operations....
