It's probably worse for those old enough to have had the chance of averting it
There are some people who will have gone from a livable world with well-known environmental patterns, to... whatever comes next. I wonder how many will notice the change without having it pointed out to them, or if it's totally a boiled frog scenario.
Me? I was born just about when the situation was about to teeter off the table. That awkward period where everything was "If we make drastic changes right now we might dodge this bullet!" - and of course no changes were made. There was a brief hop that fossil fuel's peaking might drive up costs more than the market would bear, spurring new advances in energy technology.. .and it sort of did... we found ways to make fracking and tar sand extraction cheaper.
Interestingly it did follow the pattern of grief.
Denial: it can't be THAT bad. surely they're overestimating. It' not too late, we can pull hard and turn this right around!
Anger: well... Nope. These fucking silver spoon assholes who need a new gas-guzzling car every two years and air conditioning i ntheir tool shed all for low-low-low prices? These are the shit-heels that need to sufer, not me. Them and hteir fucking pinhead politicians that they elected.
Bargaining: Well... maybe if we make little trims here, and here, we can just get grazed by he bullet? Maybe we can come up with some sort of plan to mitigate hte worst of the incoming disaster?
Depression: Nope. I'm going to inherit a wasteland, and people younger than me are going to think mad Max is a nature documentary.
Acceptance: I wonder what that'll be like. It'll b e a very interesting thing to see unfold, surely.
It's done. There's nothing that can be done to fix it. All we can do now is watch it go and marvel at what we've wrought. Humanity will survive, one of a number of creatures. I do not think our civilization is going ot come with us.
