Anyone who grew up near my childhood home of tropical Rochester, NY can likely relate to the stories my parents would tell about walking to school with 20 foot snow drifts reaching the telephone wires. Well, according to this image I just saw on BusinessWeek’s green blog, they might have been telling the truth. The surface temperature change in the Great Lakes region is profound. The poles are another story. Not news to most of us, 2007 was the second hottest year on record. Maybe the tropics and Rochester really will meet.
