This year, the waters in Lake Superior are on track to reach--and potentially exceed--the lake's record-high temperature of 68 degrees Fahrenheit

The Great Lakes are feeling the heat from climate change.

As the world's largest freshwater system warms, it is poised to systematically alter life for local wildlife and the tribes that depend on it, according to regional experts. And the warming could also provide a glimpse of what is happening on a more global level, they say.

"The Great Lakes in a lot of ways have always been a canary in the coal mine," Cameron Davis, the senior adviser to the U.S. EPA on the Great Lakes, said last week. "Not just for the region or this country, but for the rest of the world."

And it seems the canary's song is growing ever more halting.

1. Interesting. I live up here around Lake Superior and this summer is

early and hot. Our garden looks wonderful.

2. I remember the summer of 1988. Now that was hot.

It was around a month of 100 deg heat in MI. The worst I have ever seen. This summer is not even close to that yet, but I can definitely say (after talking with farmers) that our growing season is about 20 days longer than it was 30 years ago. That is definite climate change.

3. I live near Lake Erie

The local weatherman said yesterday that the water temp is 77 degrees. At least 13 degrees above normal.
