I didn’t see anything meme-like in the comment you responded to. Or even anything related to environmentalism. To me, it just looked like good health advice.

In case you don't know, there is a meme in the US that Europe don't know/don't have A/C. We do, but in some coutries there are laws banning A/C below 25°C (77°F) in public places, so (US) tourist don't get the cold air hit when entering a building like a musseum, leaving with the impression we don't know A/C.

No general A/C might be the case in regions that never needed it before (mild summers, cold winters), but their presence is increasing.

		It was fairly impossible to find a restaurant in Paris that had an AC not so long time ago. It’s totally not an issue in states.

		Something like 90% of US residential buildings have AC. For Europe, it's around 20% (for good reason, mind you). It's not a meme if it's an actual fact that many European homes are not prepared for these kinds of increasingly common heat waves, and I got the impression that the parent was showing genuine concern.
