Agreed.Jarad Diamond has written several great books. I recommend them all. However, I think you may have missed his point about the collapse of civilizations in the American Southwest. I encourage you to re-read that part . . .He feels that their collapse was self-induced through overuse of rentable resources . . .among other things. Re-read that.
Jarrod Diamond wrote a pretty good book devoting a chapter about how the climate wiped out many thriving in the American southwest.
They are already having to deal with water shortages in that region. Originally Posted by WTF

By his research, the European settlements there were established at a time of warmer climate that allowed frming and herding. They couldn't adapt to the changes in climate as it got colder from !130 onward.
