I would like to know more about the rest of the world you mentioned, since the Montreal Protocol (https://en.m.wikipedia.org/wiki/Montreal_Protocol https://en.m.wikipedia.org/wiki/Montreal_Protocol) has been ratified by all United Nations members and the European Union. Based on observed data, it also seems to have the expected positive effect.
- dukeofdoom 6y agoThey are just now starting to phase out the r22 refrigerant used in ACs with a new one r410, which it self will be phased out. So during the last two decades, the number of ACs used, in places like India and China, has grown exponentially. I've been to India. Window ACs hanging out of windows everywhere. And thats only one of the polluting chemicals. Impossible to measure how much is released in China during manufacturing. Perhaps, I've died and this is all a dream. But I do believe the world did not end yet. Despite all the articles from blowhards, preaching doom through the last two decades.

AC use in developing countries is more a global warming issue than an ozone shield issue. A lot of replacements are highly potent greenhouse gases. The ozone shield had a 4 percent loss since the 70s in average, much larger local losses aka "ozone holes". Fortunately not many people live at the north or south pole. This sheds some light on what it took to get enough support to actually change regulations: https://www.sciencehistory.org/distillations/podcast/whatever-happened-to-the-ozone-hole https://www.sciencehistory.org/distillations/podcast/whateve...
