Los Angeles, being on the edge of the desert, reflects the quirkiness of global climate, notably the influence of the westerlies in the lower latitudes.
Should the relationship between climatic instability and political economy be surprising?
No. Consider that 5000 years ago it
was these same volatile westerlies that affected the fertile
crescent stretching from Israel to Mesopotamia, the Indus and the
Dead Sea, and that early civilations blossomed more or less
simultaneously in all of these areas.
