i.e. in the next generation, unless one's home is equipped with a fancy filtration system, breathing air will have issues on its own, anywhere in the world.
Indeed! It's also quite possible that some of the humans that will live forever (or until they choose not to) may already be around us.
And, rather sadly, if climate change happens as predicted it is going to make for a pretty bleak existence. It's one reason I'm fairly happy not to have had kids.
What do you think of Emil Cioran, btw? It may pique your interest.

If you shift a normal distribution to the right even a little bit, the frequency of tail events above a fixed threshold (in this case, wet bulb temperatures exceeding the human survivability limit of 35 degrees celcius) increases more than linearly.
This is especially an issue near the equator, which will lead to climate refugees seeking colder climates, north and south.

We will be at 2000 in 640 years.
Previously those rates of change were over the course of millions of years.
It is crazy how much things have changed over millions of years, perhaps crazier to see those same changes 3 orders of magnitude faster.
Humans only started farming 12,000 years ago (which I still find shockingly recent), and humans used to farm all over the middle east (thinking if Iraq specifically, it used to be largely arable).
All in all, it's getting really spicy for next couple centuries.
* except, the earth climate system can't change that fast relative to an impulse difference of Co2 levels. It us akin to putting 10 blankets on your bed. It takes time for heat to build up (the system experiences a latent effect)
In indoor urban spaces, concentrations are probably already typically 800ppm. It might explain some of our social dysfunction...
