In terms of greenhouse it also depends on type of meat. Very acidental but europeans eat much less beef and eat pork/chicken instead. Chicken protein for example is in many cases better than cheese emission wise.

Also i don't think europeans don't use AC to save the planet. It's just expensive and it didn't use to be a problem.

Paris didn’t have air-conditioning because they sit at a latitude of 49 where in the past you might have a week maybe two of sustained high temperatures above 90°, since Paris sits at a latitude of 49 which is north of the United States-Canadian border all the way from Vancouver to the lake of the woods Minnesota.

Which is hardly air-conditioning country above latitude 49 although obviously climate change may change that, but there was no point having air-conditioning that far north in the past for two weeks of possible hot weather, a resident living in the American southwest who will never have a white Christmas ever and air conditioning was always a must.

As mentioned in other comments, what you call the past has been known for at least 30-40 years to be soon obsolete. They had enough time to prepare to this.

I wonder if pork is better than beef for the environment.

Pork, by a bunch. Lower land use, lower greenhouse gas emissions, less water use.

Not ethically better, though. At least in the US, 99% of all pork is factory-farmed, and in much of that the pigs live their whole lives in a stall too small to turn around in.

Pigs are as smart as dogs, and have personalities and emotions. I am absolutely a carnivore, but I still balk at eating meat raised through a system that just about tortures intelligent animals.

Anyways: I eat a lot more chicken and plant protein these days.
