I have lived in North Texas my whole life, and it's always hot in the summer. I think one of the big changes is how people react to it.
When I was a kid in the 80s, it seemed like most of the people in town drove around with their windows down (certainly the men - I still do this a lot and get chided from others : "Aren't you HOT?!?"). You'd go into the feedstore, etc, and there was no AC, but there would be fans going and paperweights on countertops to keep things from being blown around by them. Many of the old men wore button-up long-sleeve shirts all year round.
Yes, you'd hear someone gripe about the heat now and then (usually an old lady), but not like now. Everyone now drives with the AC blasting, and every place of business has the AC blasting. People walk around half naked, and if you wore one of those same long-sleeve shirts of yesteryear, you'd get funny looks.
I went to a funeral a few days ago and there was an after-gathering at a local house. It was held under a carport outdoors (it was about 103 or so). I still had on my jacket from the service and multiple people chided me for not taking it off.
All said, I think people are just a lot weaker and more apt to complain than in years past.
Parting shot:
I still believe in the common sense of the average man on the street, and I believe the average man instinctively knows all the climate science (along with the covid and trans madness, which is all part of the same thing: the extinction of the human race as we have always known it) is in large part bullshit. But he just doesn't know what to do about it.
