Are you referring to the Ice Age being regional? I am pretty sure the Ice Age was a global phenomenon, not regional. I also believe that the current "warming trend" has much less to do with human involvement and much more to do with both atmospheric and oceanic current changes.

No doubt it was global in a sense, but there were regions that were fairly comfortable. Even in the US south of the ice sheet there would be summer or at least some fairly decent days. The interior of Alaska was pretty much the same as it is now, although the sabertooth tigers and mammoths are gone. Large regions might be on average a little cooler but that might not be a bad thing such as in iraq and India. Was the Arctic Ocean iced over at all? There are winters in upstate New York that don't seem far removed from the Ice Age. It kind of makes one wonder if the Ice Age is really such a big deal.
