I don't mean to be divisive, but this meme-like stream of news articles and comments about Europeans being silly about air conditioning, from the drill-baby-drill nation that refused to even try to do anything about climate change, really grates on me.
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.
It would be one thing if Europe immediately stopped using coal, drastically reduced airline usage, quit building gasoline cars, but if anything it is only marginally better than the US. Europe mostly shifted their dirty work to Asia and North America, while restricting themselves from using air conditioning as some kind of virtue signaling. That's the problem as I see it.
It's clearly an op by people who don't want the story to be about a historic heatwave ravaging Europe, so instead they make it about dum Europeans without air conditioning (which they didn't need before).
