COMMENTS: Less Great
Global warming is reducing the amount of ice on the Great Lakes, allowing for more evaporation. Lower waters have made sandbars appear; they have required marinas to move docks; they force freighters to carry lighter cargoes. A decade-long drought has not helped, either. Levels are two feet lower than normal, with 12tr fewer gallons of fresh water. And they gave NBC's Lee Cowan the chance to nail his story from Duluth with this line: "Mighty Superior is becoming inferior."
