Before climate change was a thing, Malthus was making the same claims about society hitting a brick wall in the late 18th century. You then had scientists in the 19th century predicting the downfall of society because we would run out of places to store horse manure as more people could afford a horse. In the 20th century intellectuals predicted that the world would run out of food. When that didn’t work, scientists predicted the world would end in nuclear war, with rediculous props like the clock counting down to midnight. That didn’t happen, and there had to be a new boogeyman.

Even if we could push a button and solve climate change, I’m sure there would always be a reason why we need to stop having babies, turn back time, and live a subsistence lifestyle (Which is also incredibly racist, since it’s usually directed at people in developing economies, as their standard of living increases). And this is why I don’t believe most of the arguments against big houses, cars, air conditioning, are honest or being made in good faith.
