Reply to comment by ziq in A religious myth: Global collapse by Ant

Humans and other mammals simply can't survive the temperature / humidity combo we're going to reach; eventually even in the arctic (which is already on fire every summer).

I would love to learn more about this.
Separately, but related, if this is the case then presumably the rich who are busy making plans to survive the collapse are also aware of this? It makes their actions less sensible.

The planet will go on, but life as we know it won't.

If reptiles will be able to survive, I imagine that humans will have the ingenuity to survive somehow. Life as it is now this will change, I'm sure. Oddly I think we'd more than likely be better off if we died out.

Either way, I think what is important for the no-future nihilist crowd is more the reminder that global political things are multiple and segmented and different from each other, that there will be space to liberate bioregions and make meaningful anarchy as collapse goes down even as in other places authoritarianism clamps down on life.

The rich can survive underground as long as they have LEDs to grow food and can tap into deep aquifers for water. In remote countries undiminished by industry (especially fracking, which renders the water toxic). The bunkers they're building now in new zealand are pretty primitive in comparison to the underground cities they'll have to build to stay alive for multiple generations tho.

Humidity may prove breaking point for some areas as temperatures rise, says study:

What Are the Limits of Human Survival:

https://www.livescience.com/34128-limits-human-survival.html

Most humans will suffer hyperthermia after 10 minutes in extremely humid, 140-degree-Fahrenheit (60-degrees-Celsius) heat. Death by cold is harder to delimit. A person usually expires when their body temperature drops to 70 degrees F (21 degrees C), but how long this takes to happen depends on how "used to the cold" a person is, and whether a mysterious, latent form of hibernation sets in, which has been known to happen.

The boundaries of survival are better established for long-term comfort. According to a 1958 NASA report, people can live indefinitely in environments that range between roughly 40 degrees F and 95 degrees F (4 and 35 degrees C), if the latter temperature occurs at no more than 50 percent relative humidity. The maximum temperature pushes upward when it's less humid, because lower water content in the air makes it easier to sweat, and thus, keep cool.

The rich think theyre invicible cuz until now they have been. Ego is powerful. They think they can buy themselves out of anything.
