First, I completely agree. Besides regional disasters, there will be generalized crises pertaining to particular societal systems and processes.

The most important system for which climate change is coming is the globally integrated agricultural system. Civilization depends, today as ever, on relatively few people growing enough food to feed everyone. When that system collapses cities will collapse. It will be the end of the era of civilization, in which culture (essentially, all human output) is dominated by the existence of large cities.

I am convinced that the one needful thing we must accomplish, before the end comes for civilization as we know it, is to recognize mutual respect as the ethic of justice. The small, isolated communities that will be the scattered remnants of the era of civilization can use that ethic as the basis of governance to achieve truly just societies. It contains within it a paradigm for establishing a (just) monetary economic system.
