A couple things: 1) "overrunning the planet with people, mass starvation and disease were to be rampant" These were never consensus viewpoints. Anthropogenic climate change, in the low to mid single degrees Celsius, is. 2) There's a whole lot wrapped up in the word adjusting. If it's to mean anything more than "survive" (as a species--many individuals' lives would be cut short), it has to include an active component. We "adapted" to the ozone hole. Yes, that involved new technologies and habits like better sunscreen and norms around using it. But it also involved people getting together and banning substances that contributed to the problem. That made individual-level adaption much less costly than it would have been otherwise.
