What happens to an economy when it's too hot to work?
bloomberg.comStanding outside talking to friends after the sun set, where it's still over 100F outside: I could feel brief (minor) chills pass over me as I'd sweat in bursts and it'd instantly evaporate.
And back when I was cycling, I'd start summer rides about an hour before dawn, when it'd be at its coldest (sometimes 90F for the low). I learned to not rub my face because I'd have salt crystals from dried sweat, and they would abrade skin near the corners of my eyes.
The difference between sun and shade is pretty big too.
Heat stroke is a life-threatening medical emergency (e.g. call 911) when they body has gotten so hot that organ systems that are capable of regulating temperature start malfunctioning, and things can go downhill extremely quickly from that point.
I think the disconnect between many people hearing "2C of warming" and the overall effects that will have is grossly underestimated. I kinda wish we could talk about how much raw energy that is ... even if we use American units of barrels of oil, or something.
The real conversation we should have is about money talking; a huge amount of assets are facing being stranded by insurers. Insurance doesn't really care about ideology, they care about making money, and so the fact they are losing money to climate change is pretty irrefutable evidence. Though right now politicians are just reframing this as "greedy insurance", which isn't exactly untrue.
Insurance prices risk. If risk goes up, so do prices. They will not lose (much) money (or not for long) [1], your insurance will just get a lot more expensive, maybe to the point you can no longer afford it. If the government tries to control prices, then insurers will just exit the market, or the only entrants will be severely under-capitalized, merely providing the veneer of insurance (e.g., because your mortgage lender requires it). This is already happening in Florida and Louisiana [2]. These insurers will simply go bankrupt in the event of a catastrophe, and you will be stuck with the loss.
[1] Technically, in a competitive environment, many insurance companies will operate with a (small) underwriting loss, but they make up the difference by investing the float during the time between when they collect the premiums and when they pay out on claims. They will not operate with an unbounded loss.

The problem is that the loudest voices in the global discussion are people living in relatively cold-ish Western climates because, well, we are the rich and powerful people. And for many of us (maybe bar the Southern-most part of the US), even 10 °C increase of yearly average temperatures or even peak temperatures would still be perfectly fine.
The fact that 2 °C is probably enough to render the space of potentially billions of people uninhabitable is completely outside of the experienced reality in Western countries, we cannot relate from our lived reality to theirs.
And that kind of disconnect is prevalent among any kind of discourse in humanity. The fact that we can even do so, that right here on this website we have people worth billions of dollars (e.g. sama is Sam Altman!) debating with people that barely scrape by on their national poverty level, is a wonder that would have been unimaginable 200 years ago. Human biology, human society hasn't evolved mechanisms to keep up with our technological progress, and it breaks apart everywhere.
Do you drive to Norway for your beach holiday?
Actually look at median temperatures in the US. Summers in Atlanta and Chicago are remarkably similar as it is.
It's wild to think that we might be only 10 years away from that line in the sand we marked. Hopefully they are wrong but I fear they are not.
Findings from 2025 -
> Over the 12-month period, 4 billion people — about 49% of the global population — experienced at least 30 days of extreme heat (hotter than 90% of temperatures observed in their local area over the 1991-2020 period). [1]

Putting India in a spot where if it would cease relying on coal power in 30-40+ years it would cause the temperature to rise.
The good thing about green energy is that one there is a sufficient amount of it, it can also be used for extensive indoor air conditioning.
The heat doesn't vanish with AC, at least not unless you use a very expensive deep-underground well as a heatsink instead of the open air.
Even if everyone has AC indoor - the air outdoor will still be too hot and, most likely, humid, with all the expelled heat from the ACs added on top of that. Animals won't stand a chance, especially wild ones, and humans that absolutely have to work outside (e.g. policemen, firefighters, EMS) will be just as impacted.
We have to face the reality: large parts of the globe, impacting billions of people, will be unable to support human and a lot of animal and plant life during the summer months if climate change continues at the current pace in a short enough time that most people reading this text will eventually witness this.
AC is heat pump like your fridge, it moves the heat from inside to outside, meaning the average between the two sides stays in equilibrium, it doesn't create new heat for the outside to be a measurable impact on the planet's heating. Everyone running refrigerators in their homes to keep the food cold, and transferring that heat to their kitchen, doesn't heat up the cities and planet.
You're also contradicting yourself. If the world is indeed getting fucked heating wise like you say, then at least it will be less fucked if you have AC where you live than trying to live without AC and being more fucked. The planet will not be saved if you give up on having residential AC, you'll just suffer more versus those with AC. So it makes sense form an individaul self preservation perspective.

It ought to be great. Takes no energy, sends heat through the infrared window back out into space where it came from.
Yes, there are safety measure built in but I just give them a helping hand.
In USSR/Russia during especially hot summers the team/orgs i worked at (outside on construction and in the other years inside as programmers (no ACs were yet widespread there back in the 199x)) were working at night skipping the daytime siesta-style.
