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.
> 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.

Et l’air conditionné ?
> Airconditioning at high temperatures leads to more than 20% extra power demand, while at the same the power grid becomes less effective, nuclear and gas fuel plants provide less power because of warmer cooling water and transformers are more likely to overheat leading to power outages.
@joachim En attendant, apprendre la respiration rafraîchissante du Yoga 🙂
(je confirme qu’elle rafraîchit bel et bien).
