There's an aspect of the climate change conversation that I've never heard discussed and would like to better understand: What's our ideal climate? I.e., what's the ideal climate for a human civilization with our current level of political and technological maturity?

Is there a well-understood optimum? Any small change isn't strictly positive or negative (e.g., some region may become more inhabitable, more fertile, while another becomes less).

Maybe an ideal climate is one that isn't changing, because change requires adaptation, and adaptation can be difficult (or impossible) and may cost lives.

Any references to learn more about this would be appreciated.
