It's official--the "Healing Our Waters-Great Lakes Coalition" thinks that we're all idiots

See the story here, and check out this laughable paragraph from their web site:

Close your eyes and think of the worst disaster movie you’ve ever seen, OK, do you have it set in your mind’s eye? The Healing Our Waters-Great Lakes Coalition is releasing a report that shows the expected impacts of global warming on the Great Lakes – nearly 95 percent of this nation’s fresh surface water – are much more devastating than anything you could have imagined.

From their perspective, it's a problem that we've already got actual data on Great Lakes water levels extending back to 1860 or so.

Since then, Great Lakes water levels have risen and fallen many times, without any apparent correlation with CO2 levels, and also without resultant unimaginable mega-disasters.
