The climate crisis will solve itself when flying, eating meat, gas guzzling cars, etc. are impossible to use because the climate crisis has made life an (as of today) essentially unimaginable hellscape. Sure it’ll be a few centuries of abject misery but as a result the world’s population will contract a lot and things will “reset.”

If people today aren’t willing to change their lives (and they clearly aren’t), then it’s time to enjoy the ride and hope we die (fingers crossed) before things get awful (which they will).
