Japan recorded the highest ever temperature of 41.2 degrees Celsius on Wednesday, beating the previous high of 41.1 C marked in 2018 and 2020. Authorities are strongly urging people to take precautions to avoid risks of heatstroke.

The mercury hit the above-human temperature of 41.2 C in the city of Tanba, Hyogo Prefecture, at 14:39, while two cities — Fukuchiyama in Kyoto and Nishiwaki in Hyogo — also recorded extremely high temperatures of 40.6 C and 40 C, respectively.

I can estimate other metrics in my head, temperature usually foils me.

Nothing will meaningfully improve until the rich fear for their lives

I usually downvote the repetitive slogans around here, but this one certainly bears repeating. One little CEO gets shot, everyone loses their MINDS!

[–] WindyRebel@lemmy.world 0 points 2 days ago* (last edited 2 days ago)

I can’t tell if the repetitive slogan you refer to is the one you replied to or the slight tweak of a quote from The Dark Knight that you used in your own post. 🤔

[–] Thedogdrinkscoffee@lemmy.ca 14 points 2 days ago* (last edited 2 days ago)

It still won't improve then, though it may get less bad, less quickly. Our climate change crisis is effectively permanent and cumulative.

Edit: with a roughly 20 year delay between emissions and warming. (Before tipping points)

"Take precautions" = Run A/C = Problem gets worse.
We're really here, aren't we. Hope humans get good at terraforming or building tunnels, real fast.

From 2016 to 2022, 80 percent of global carbon dioxide emissions were produced by just 57 companies.

https://www.smithsonianmag.com/smart-news/since-2016-80-percent-of-global-co2-emissions-come-from-just-57-companies-report-shows-180984118/

Emitted 3.2% of total greenhouse gas emissions when refrigerants are included.

https://ourworldindata.org/air-conditioning-causes-around-greenhouse-gas-emissions-will-change-future

A/C is a negligible amount of the problem and in these type of weather is a necessity, lest vulnerable people like seniors die from heat stroke. You could 10x AC usage and it still wouldn't even match what corpos emit. We have way bigger issues than more AC use.

One thing doesn't negate the other.

I'm honestly shocked that it's already at 3+% Think about how it changes in the future when it further warms. Also, it has local effects, of further firing the situation, i.e.it get's measurably warmer in cities. Take Phoenix for example, in the future, there may be times, if you don't have an extremely well working respiratory system, that you'll die outside because of heat stress...

[–] shalafi@lemmy.world 2 points 2 days ago

Meh, not like we humans aren't buying and burning those company's products. Maybe I'm doom and gloom, but I put the issue at our ridiculous population.

FFS, there were 3.7 billion of you apes when I was a kid. Now we're at 8 billion with no sign of slowing soon. Is no one else shocked this happened within a human lifespan?!

Is the immigration hate any wonder? All we've seen is more and more people, and the immigrants are, GASP, different people. "Send 'em back!" That policy will fail on a couple of levels, but that's where our emotions are at. Any sort of mammal population will freak out and go violent when there's too many of 'em.

There isn't any answer but Malthusianism. Y'all gonna have to die back until things get better. But not me and mine! :)

[–] CaptDust@sh.itjust.works 1 points 2 days ago

I didn't mean to imply it's the biggest problem, just pondering on the irony of the current advised defense also contributing. I could imagine such a jump as climate control is increasingly demanded for survival.

[–] Sterile_Technique@lemmy.world 9 points 3 days ago

Hope humans get good at terraforming or building tunnels, real fast.

...at this point it's looking like the best case scenario is for humans to hurry up and go extinct so the damage can stop and minimize the number of other species we drag down with us.

[–] mateofeo85@lemmy.world 10 points 3 days ago

The rich already have it.

[–] psx_crab@lemmy.zip 2 points 2 days ago

Or we build our house like hobbit or teletubies.

[–] DarkCloud@lemmy.world 28 points 3 days ago* (last edited 3 days ago) (3 children)

Climate change is here early. Probably because of undeclared or regulated methane release which is a far worse gas as far as trapping heat. Traps waaay more heat than carbon dioxide, and the US, Russia, and China dump huge quantities of it.

Not to mention the pockets of it in the melting ice caps.

[–] Saleh@feddit.org 24 points 3 days ago* (last edited 3 days ago)

We are on the trajectory that has been foreseen by climate scientists quite well. The problem is that a rise in average temperature does not just mean where it used to be 35°C max. it will be 36.5°C max. but rather the extremes will increase much stronger, so you get 40°C or more even though the average only increased by 1.5°C

As for methane leaks, we can detect them quite well nowadays using satellite imaging. You are correct, that the US, Russia and China show substantial leaks, India, Iran and a bunch of others are also in the mix.

[–] paraphrand@lemmy.world 6 points 3 days ago* (last edited 3 days ago)

I suspect you’re correct purely because Trump stopped methane monitoring.

Also from all the methane that animals release too

[–] k0e3@lemmy.ca 11 points 2 days ago (1 children)

The real question is, how will we blame this on tourists and other foreigners?

[–] tigeruppercut@lemmy.zip 4 points 2 days ago

When they say "This is a PEN!" the plosive sounds they use are so aggressive that it heats up the air around them. Honorable nippongo doesn't contain such violent sounds, so clearly this heat is due to the gaiks.

[–] winkly@lemmy.world 12 points 3 days ago

That’s hot 🥵

[–] wazzupdog@lemmy.blahaj.zone 10 points 3 days ago (3 children)

Hottest temp I've ever been in was over 50. it was painful just walking outside.

[–] punkwalrus@lemmy.world 8 points 3 days ago (2 children)

I have endured a Phoenix, Arizona heat at just under 120° F and opening my motel door was like opening an oven to check on something you're baking. Our rental car had to have the AC on for about 3 minutes before sitting in the seats wasn't searingly painful. It took about 5 minute for the steering wheel to be comfortable enough to grip for more than a few seconds.

[–] Flocklesscrow@lemmy.zip 9 points 3 days ago

The city of Phoenix shouldn't exist. It's a monument to American hubris.

[–] Joeffect@lemmy.world 8 points 3 days ago (2 children)

But it's fine... it's a different kind of heat....

[–] cannedtuna@lemmy.world 8 points 3 days ago (1 children)
[–] SheeEttin@lemmy.zip 2 points 3 days ago (1 children)

Ackshually, combustion releases water vapor. If you have a gas stove, you might have noticed condensation on the side of a pot of water when starting from cold. That's why.

[–] deegeese@sopuli.xyz 2 points 2 days ago

Ackshually hot air has a higher vapor capacity, therefore the fire is a dry heat, and only away from the fire does it become moist.

[–] shalafi@lemmy.world 3 points 2 days ago (1 children)

Meh, that's pretty fucked if it's humid. I'd do 50C in Death Valley before 40C in Florida.

Think the hottest I remember is 48C in Oklahoma. LOL, I was mowing lawns for a living and mom was calling to scream I should come home. At the time, I was young and used to it.

Speaking of humid. Put in a little 14' above-ground pool. Jumped in the other day to cool off while working in the yard. For the first time I emotionally understood wet bulb temps. Soaking wet did nothing. Was fucking around at camp today, shirt instantly soaked, no wind, and no amount of water was cooling me. Scary stuff.

[–] Toneswirly@lemmy.world 1 points 2 days ago

Ambient humidity prevents evaporation which is how sweat and water cool you off. Thats why humidity feels like extra death.

[–] Baggie@lemmy.zip 1 points 3 days ago

Same, I went for a walk just to feel it. It was for about 5 minutes, I was fine, but it was definitely something that could kill you if you were in it for too long.

[–] jared@mander.xyz 7 points 3 days ago
[–] Asafum@feddit.nl 5 points 3 days ago

That's how hot it has been in the factory I work in for like the last week already... It's disgusting. Between 102F-106F

Hope they get some relief soon!
