World wide? No.
I think you’ll see pockets of good choices and efforts being made, perhaps down to cities, that may or may not mitigate some of the damage, or allow for a more resilient response to ongoing events.
Catastrophic level collapses that take decades will be survivable, but not at the quality of life that most are accustomed to, leading to those on the bottom dying and suffering in greater numbers. Life expectancy will continue to drop. The world will be changed, it’s just a matter of how much civil unrest this engenders as resources become scarce and global markets less reliable or available.
I’m not sure how much ecofascism we’ll actually see, though, as the people who lean/are fascist are the ones least likely to believe climate change exists, and given how conspiracy style thinking has flourished with Covid, I really can’t be sure that they’ll ever “snap out of it” and start clamoring for the change that’ll actually do anything. I think it’s more likely to see increasingly angry people who demand more for their homes and less for others, which I guess could be ecofascism? But without actually believing climate is changing; it just happens to be dumping a ton more rain for whatever reason.
