I was camping out in Okeechobee last week. Two days in a row the "real feel" temp was 108. I was drenched in sweat just from sitting in the shade reading.

I've been saying for years that we need to evacuate the state. Thankfully, between RoevWade and DeSantis it looks like my family is finally coming around. Now if I can just reach my close friends.

that's so sad. it's possible to escape. i grew up in arizona (lol) and made it to north of the 45th parallel now. we had our first heat wave of the year (above 90f) last week. it rained every day in april.

I live MUCH farther north, and I feel the same, though it was only for a couple weeks that it got as bad as you described

RIP to a dedicated mother, we will miss her

I'm sorry for your loss :soviet-heart:

I just need to go back to Czechia idk why my parents roped me into this shit. The mountains are cool and nice and a good temp all year round. I feel like a nicely watered tree there :meow-melt:

I FUCKING LOVE LIFE :spongebob-party:

I can't regulate my temperature well in general but heat is so much worse because it fucks with my head :/// I can't sweat that much either so I dont get to cool down unless I'm in air conditioning

Except: shifting climate patterns are predicted to bring increased moisture to a lot of the desert southwest without bringing the temperatures down. Also Phoenix will have no usable water inside a generation at this point

Already happened in the PNW last year with the heat dome, though with less infectious strains, and IIRC there was only a small spike in cases. The baseline's already so high it kind of doesn't matter.

A mild July in D.C.

Going to do a few generations of natural selection for smaller, browner people with a high humidity tolerance.

so wet bulb is a 'perfect' condition between humidity and heat, we use water to cool our bodies and if humidity is high enough it nullifies the ability for sweat to cool you faster than surroundings heat you up

sahara is dry as a bone so itd need to get way hotter for your sweat to not work, or wetter. idk why wetbulbs dont seem to happen so often in jungles tho... seems ideal

Wet bulb will kill most of us, then there's excess CO2 in the air which start to affect the brain at about 600ppm (office buildings already sometimes get as high as 2000ppm at current 460ish levels), there's famine, flooding, fire, pandemics, etc. People who think we're gonna survive this are being very optimistic.

A lot of it is a cumulative effect too, you can survive stretches of high temp/humidity but in the future when it becomes a months long season that will be increasingly difficult. Also FWIW for several years at this point subsistence farmers in central America have been dying early from renal failure brought on by years of hard labor in ever hotter conditions.

Dry heat vs wet heat.

The jungle people only make it by hiding underneath the fauna that the rainforests provide. People having to do manual labor in them drop dead all the time. I live in one of the hottest regions of Central America. There was one point when it got up to 112 degrees Farenheit. It was very dry and my head felt like it was spinning if I was out for too long. There's going to be a point where I'll have to move and I'm still not sure where that will be.

what is this supposed to tell me exactly?

The study? That a couple dozen random Americans from the northeast suddenly thrust into high temperatures suffer horribly much sooner than expected based on existing research. People adapt to the temperature they live in long term, so someone used to carefully climate controlled environments struggles to handle heat.

Also people who live in the most extreme climates have developed various ways of mitigating that, whether in things like clothes that reflect sunlight and whisk away sweat while remaining breathable or in architecture that helps keep living and working spaces cool by doing things like channeling wind through cisterns or cellars and building cities to create strong, shaded breezes, along with behavioral things like just not doing heavy work during the hottest times of day.

Also note the population density of those places. Some humans can survive there, but not a lot of humans.

For the Sahara, I found that one of the hottest areas is Ouargla, Algeria. The highest forecasted temperature will be 47 degC with rel. humidity of 6%. This is equivalent to a wet bulb temp of 20 degC (< 31 degC limit).

For jungles, Belmopan, Belize has forecasted temps for this week up to 33 degC with 56% rel. humidty (wet bulb temp = 26 degC).

you can use this calculator with values from different cities

Please stay safe comrade

"It's a dry heat" is a real thing, the dryness lets you cool by sweating. If it is a wet heat ur dead

The wet bulb point is the temperature + humidity when sweating no longer cools you down. Since sweating is how we avoid heat stroke this is bad.

The worry is that a densely populated area, usually Bangladesh is where people are worried about, is going to get at or close to the wet bulb temperature for a long period of time. And if it's hot and damp enough, and it lasts long enough, then the theory goes that everyone without access to AC will eventually die. Like entire cities, entire provinces kind of thing. The less developed an area is the more vulnerable it is because it will have less access to AC and refrigeration. Old people die first because they're much more vulnerable to heat stress. But young people will die en masse too if it's bad enough for long enough.

I’ve lived in Florida and Colorado, and visited Arizona in the summer. I would take 105F in Arizona or Colorado over 90F in Florida. When it’s dry you go through short cycles of feeling hot and then a sudden cool breeze, and never get too wet.

That’s how sweating is supposed to work.

In Florida you walk outside and become damp, and then the longer you’re outside you become wetter and wetter while also your body temperature increases.

What a lot of countries with really hot weather do is stop work for the hottest part of the day
