Yeah, I’ve noticed the lack of insects, and also different plants growing than I remember from when I was a kid, not all too long ago. Every once in a while someone will be talking to me about the weather and how freakish it is, and they’ll suddenly get quiet if I use the word “climate” instead of just weather, because they were (and maybe still are?) denialists.

The thing about mammals is that at least some - ourselves included - can migrate. If we have to, we’ll set up banana plantations on Antarctica, and there’s no known scenario where it gets that bad. Others are not so lucky, though.
