First, anyone who tells you what weather patterns will be like in 50-100 years is full of it. I've read conflicting science on ocean level increases, but it seems likely that levels may rise significantly enough to pose a problem for someplace like New Orleans, which is already in the sink.

As to agricultural patterns, the Anazasi farmed the deserts of the Southwest during the last warm period, and their decline as well as the Mississippian cultures like Cahokia are right on the downturn. That is, the Middle Age Warm period permitted GREATER cultivation and the cooling trend around 1300 or so dried em out.

I have yet to see any science that would indicate that a warming trend correlates with dessification. If you could point good, solid, papers out to me, I'll be glad to read them. But the historical record, including ice cores, have indicated that we are in a period of atmospheric CO2 FAMINE compared to previous periods. And the record indicates that greater atmospheric temperatures may actually be beneficial. Plants love CO2, you know.
