"The ironic result, according to this theory, is that "global warming" could result in a massive temperature drop in upper latitudes, just as it did 13,000 years ago. Geez, ya can't win."

It sure seems to me that humanity has taken a "snapshot" of conditions around 1975 and is trying to preserve that, period. When I read of changes I can't help but think that if the gorgeous, scenic Grand Canyon were starting today there would be a massive PR campaign showing how farmers were getting screwed over and we'd have the Corps of Engineers spending billions on erosion control.

That isn't to say we shouldn't minimize Man's impact upon the changes. I think we should, but continents seem to float, gravity works, and when you look around this Universe it's amazing, flat amazing, that something as fragile as life has had a stable platform this long.
