If you’re in a developed nation, and unless you expect the earth to go through an irreversible Venus syndrome in the next century, I don’t see how this argument is anything more than a fig leaf for more fundamental social ailments. What would you say to someone in 700 AD, for whom the next 1000 years were more likely to be objectively worse in terms of quality of life than the next 1000, even accounting for what climate change is expected, intervention notwithstanding.

The costs of childcare, housing and education have exploded, and even establishing the relationship needed to do the deed in the first place is arguably harder than it s been. That sucks and there’s little any individual can do about it, despite the rhetoric blaming it on the generations most likely to be impacted by it. Climate is a convenient scapegoat to deflect blame, but we were never to blame in the first place.
