It seems that apocalyptic thinking is endemic to the human condition.
I've always seen the christian apocalyptic perspective as mostly metaphorical, which generally puts limits on how deranged you can get with it. Yes, there are those sects from time to time that insist that on March 3rd, 2:00pm, this year, the world will end, but as far as I know, the dominant christian dogma on that is "soon".
The climate apocalyptic perspective has always seemed unpersuasive to me, because even if you managed to thanos snap all of western civilization out of existence, China and India aren't going to behave differently, unless forced by threat or application of violence. There has always been zero chance of effective coordinated global action on this.
Let's stipulate to a hellish, hothouse earth if china and india don't decarbonize. Assume every apocalyptic model is 100% true, and the tipping points are days away.
There is nothing that can be done. No virtue signaling will change ground reality. No amount of personal effort will move the needle. No amount of national effort will move the needle.
The only thing left to do is get right with your deity of choice, and blame as many other people as you can to take the focus off of yourself.
And if we're lucky, maybe, just maybe, it'll all turn out that the apocalypse is delayed but one more day at a time.
