Think of it like a house. If you are sitting in room temperature room and the temperature rises or falls, it's going to be less ideal. In a similar way, if the change is small and reaches a new equilibrium, then you can add more insulation, change windows, open windows... whatever. But that carries a cost to you.
We are at the human-stable peak of stability and production, so to speak.Are we (or were we) at a perceived peak of environmental stability and productivity?
Anyway, the changes in global warming take so long that the real issues aren't with the temperatures - least, not in the next few decades. Tying global warming to catastrophic political issues has a lot more to do with economic issues, like barriers and restrictions and political issues, like industrializing the rest of the world (poverty, etc.)
