They 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.
