The only thing that I can personally see that changed somewhat since my childhood (in the 80s, in central europe) is there are fewer winters with snow. It used to be almost a certain that you'd get a month where even in the lower parts of the country you get like 30-50cm deep snow cover and sometimes more. It's rare the last ~15years.

But the spring, summer, autumn feels the same. Lately (the last 3 years) it feels on colder side. I personally would prefer to add +5C or sometimes even +10C 🫠.

So when I see the "world is ending! we are going to burn alive later this year if we don't end capitalism now" people, it's a headscratcher. Is this how nocoiners see bitcoiners? But I digress...

Any *reasonable* measures to cut back on pollution, esp. toxic stuff, forever chemicals and (micro)plastics is a good thing in my book.
