The Montreal Protocol was designed to save the ozone layer, but it may have ended up saving the planet.

It turns out that the ozone layer collapsing could have set in motion a disastrous sequence of events, creating a climate that hasn't been seen on Earth for 25 million years within just one century. Just as well we listened to the scientists on this one, eh?The previous video in this series: https://youtu.be/vxKcqM5aSA4REFERENCES(1) Global Ozone Research and Monitoring Project, ‘Scientific Assessment of Ozone Depletion: 2018’, WMO, 2018(2) Yes I know that CFC emissions rose in China recently, but seemingly that has actually been cracked down on https://www.climatechangenews.com/2021/02/10/study-suggests-chinas-crackdown-illegal-cfc-gases-working/(3) https://treaties.un.org/Pages/ViewDetails.aspx?src=IND&mtdsg_no=XXVII-2-f&chapter=27&clang=_en(4) GWP-100 data, taken from IPCC AR5 - https://www.ghgprotocol.org/sites/default/files/ghgp/Global-Warming-Potential-Values%20%28Feb%2016%202016%29_1.pdf(5) https://pubmed.ncbi.nlm.nih.gov/22924540/(6) https://www.pnas.org/content/104/12/4814(7) https://www.nature.com/articles/s41586-021-03737-3You can support the channel by becoming a patron at http://www.patreon.com/simonoxfphysCheck out my website! https://www.simonoxfphys.com/---------- II ----------My twitter - http://www.twitter.com/simonoxfphysMy facebook - http://www.facebook.com/youtubesimonMy insta - http://www.instagram.com/simonoxfphysMy goodreads - http://www.goodreads.com/simonoxfphys---------- II ----------Music by Epidemic Sound: http://epidemicsound.comSome stock footage courtesy of Getty.This video is about the nightmare future humanity avoided by passing the Montreal Protocol limiting emission of CFCs. In signing the Montreal Protocol, the UN unintentionally avoided a hellish future climate with CO2 concentrations of 900ppm by the year 2100. As well as a destroyed ozone layer with a surface irradiated by UV light, this avoided future featured a climate choked with carbon dioxide, with plant life struggling to photosynthesise. The Montreal Protocol was designed to protect the ozone, but ended up potentially saving the planet, it's atmosphere, and biosphere.
