Great Lakes are "Canary in the Coal Mine" July 26, 2010 : 1:22 PM

According to Cameron Davis the senior adviser to the U.S. EPA on the Great Lakes, "The Great Lakes in a lot of ways have always been a canary in the coal mine”

At a meeting of the Interagency Climate Change Adaptation Task Force last week it was reported by Climatewire that:

-Total ice cover on the lake has shrunk by about 20 percent over the past 37 years

-The waters in Lake Superior are on track to reach -- and potentially exceed -- the lake's record-high temperatures of 68 degrees Fahrenheit, which occurred in 1998. Davis went on to say, “"This year is just tremendously anomalous," he said. "This year ranks up there with the warmest water we have ever seen, and the warming trend appears to be going on in all of the Great Lakes."
