Editing Ozone depletion (section)

=== Location of hole ===
Some people thought that the ozone hole should be above the sources of CFCs. However, CFCs are well mixed globally in the [[troposphere]] and [[stratosphere]]. The reason for occurrence of the ozone hole above Antarctica is not because there are more CFCs concentrated but because the low temperatures help form polar stratospheric clouds.<ref>{{cite web|url=http://www.faqs.org/faqs/ozone-depletion/antarctic |title=ozone-depletion FAQ, Antarctic |publisher=Faqs.org |access-date=April 6, 2011}}</ref> In fact, there are findings of significant and localized "ozone holes" above other parts of the Earth, such as above Central Asia.<ref>{{Citation |last1=Chen |first1=Sheng Bo |title=Stratospheric ozone change over the Tibetan Plateau |journal=Atmospheric Pollution Research |volume=8 |issue=3 |pages=528–534 |year=2017 |bibcode=2017AtmPR...8..528C |doi=10.1016/j.apr.2016.11.007 |last2=Zhao |first2=Liang |last3=Tao |first3=Yu Long}}</ref>
