> Our survey of the climate record from station data reveals many global TW exceedances of 31° and 33°C and two stations that have already reported multiple daily maximum TW values above 35°C.

I only did a quick skim of the paper, but I couldn't actually find which two stations they were talking about. I'm curious as to which two places they were.

Or.. Build more basements and underground shelters.

No, it wouldnt work as the heat would have nowhere to go. And the mid east people didn't do it - https://en.m.wikipedia.org/wiki/Windcatcher Instead you build and live in highrise/towers - that gives cheap ventilation which is a half the solution. And I liked the siesta and the following it very active life till deep night in Spain - another natural adaptation to hot climate. It makes for much calmer and steady life…

I mean, I'm sure this is valid in some places but having lived in high rises relatively far north in Canada let me tell you it is very possible (and in my experience very common) to build high rises that retain heat so well they basically bake the occupants in high heat/humidity.

I doubt most of North America's high rise apartment buildings above some latitude are particularly well equipped for this, so there's almost certainly a shift required in how you build them.

It's hilarious to me that people somehow think hot is MUCH more dangerous than cold. If you do any homework you will see which end results in more deaths.

There's a far larger area of the world which is too cold & dry for human tolerance, yet people survive & thrive there. Probably the same for places which are hot & humid.

There are some interesting documentaries on Yakutsk, the "coldest city in the world".

Kim Stanley Robinson's recent book The Ministry For the Future starts with a very disturbing scenario: A heatwave with a "web bulb" temperature of 35 Celsius. It turns out, in those temperatures, even young and healthy people can't survive. Combined with power outages, as happens in the book, everyone living under such a heat wave will likely die. It's looking increasingly likely that such heatwaves are possible in t…

A lot of new technology could potentially solve this problem.

There are certain types of roofs being installed called cool roofs that reflect heat and don’t absorb it that keeps the inside of building a little cooler.

If you clicked on the link you are commenting about, you would have learn that we are talking about 35°C wet bulb. Which will kill you, whatever your age, your health, or what you try to do to overcome it. Basically, without air conditioning, so without energy, you are dead. Cold, instead, will not kill you if you are able to cover yourself with a sufficient coat and/or you are able to start some fire. Most places in…

People who own a car in Yakutsk must leave it running all winter, or the oil will freeze & cause engine damage. A toolbox is always present in the car, since being stranded on the road, without cell phone signal, will lead to death within a couple of hours. Having a part of your ears exposed for 15 minutes will lead to frostbite. Cold is no joke...

Well, one can warm up by eatnig lots of food, wearing other critters' skins, and burning stuff; all of which are stone-age (or earlier) technologies. Cooling down requires air conditioning (modern tech) or access to natural cold water (privilege)

Or digging a hole or holes, and running air and or water through them, like has been done for thousands of years in very hot places.

Which isn't likely to be a reasonable solution when we have a few days notice of an extreme hot weather event reaching a region for the first time. Predicting how common they'll be in a given place and arguing to prepare beforehand for what will likely still be a somewhat rare event (with unknown exact frequency) is hard.

Similar question to this that I've been wondering this wildfire season -- at what point is AQI (Air Quality Index) too severe for human tolerance? The scale tops out at 500, what happens to a person if the air is even worse than that?

Some sensors near Medford, OR are reading in the upper 400's and even low 500's -- what happens if it hits what would be the 1000's if the scale went that high?

I'm mostly thinking of particulates, but AQI includes other gases like CO, SO2, NO2 so maybe those would be more dangerous than particulates (and certainly harder to filter out)

I wonder how practical it would be to sink 30 foot deep concrete tube shelters with a ladder and a lid. They could serve as emergency daytime shelters and someone could climb out at night to search for a location with working power or cooler weather.

If mankind has to start living at night because daytime is too hot, at least night owls will no longer have to shorten their life expectancy to fit into a daytime schedule.

In other words, a fire.
