Non-survivable humid heatwaves for over 500 million people
> Researchers at MIT warn that if climate change remains unchecked (…) over half a billion people will, from 2070 onwards, experience humid heat waves that will kill (…) within 6 hours.

> Things like this don't just happen suddenly.
> While the paper here says "from 2070 onwards", the first cases of this occurring will happen well before then.
> At first, it'll just be something small. Maybe Dubai will hit 130 degrees with 80% humidity for a day or two one summer in 2030. A few people will die, but most people will be okay, thanks to air conditioning.
> Then a few years after that, it will begin to spread and become more common. First Dubai, then Basrah and Bahrain.
> It'll start off as a day or two of not being able to go outside due to extreme heat and humidity. A "warning", like a "clear the air" day or something. Not a big deal.
> A few years later it'll be a few days.
> A few years after that, a week. Then it'll spread to other coastal cities that are near the tropic of cancer and tropic of capricorn. Mumbai. Colombo. Ho Chi Minh City.
> That's when thousands of people will begin dying, every year, due to severe heat and humidity.
> But we aren't done yet, because after that, it'll begin spreading to first world countries. Cities such as Darwin (Australia), Fukuoka and Osaka (Japan), Shanghai, Shenzen, Macau (China), Taipei (Taiwan), Pensacola, Tallahassee, Tampa, Baton Rogue, New Orleans, Houston, Mobile, Phoenix, and San Diego (United States).
> Cities further away from the tropic of Cancer/Capricorn will maybe have one or two days of un-inhabitability- at least, for a while anyway. At this point, however, much of the middle-east is uninhabitable for 2 or 3 months of the year, causing severe political instability, wars, famine, etc.
> *Then* we will hit the year 2070, and it will only get worse from there.

(Sans oublier que les conditionneurs d’air utilisent des gaz réfrigérants bien pires que le CO2 en matière d’effet de serre — plus on en fait pour lutter contre la chaleur, plus accentue ladite chaleur en faisant empirer le climat.)
