Generalising about generations (one of the most absurd ways of dividing people up) is not helpful. Some of the people making/distributing those dumb 1976 memes on TikTok (and elsewhere) look like they were barely alive in 1976. Conversely, look at the various climate change protests and there's plenty of "boomers" there.
It is however true that the boomer generation has held the electoral power during the years that mattered most and refused to do enough. I don’t think it’s chance that their most popular papers were all the most strident climate deniers.
Younger people should vote more but tbh by the time I was old enough to vote it was already too late to avert what’s happening.
I don’t see any sentiment of “whoops we got it wrong, let’s do what we can now!”. (Or any gratitude for the sacrifices younger people made during lockdowns, but I digress…)
But it is frustrating because boomers are basically the law makers and voting majority in 2022.
I have the same experience with so many boomers as the parent. "Hottest summer on record? Aw, I love hot weather". "When I was a kid, it was so hot the tar on the road would stick to me feet?!" etc.
