    Who is ‘wrong again?’
    The water levels in the Great Lakes have been measured for a long time, and in fact NOAA keeps track of them

    A quick glance will tell anyone that the water levels rise and fall over time. In fact, compared to the median, the water levels for Lakes Superior, Michigan-Huron are lower. St. Claire is about the same, and Erie and Ontario are higher.

    If any research is done on claims about water levels, you can find some publications said it is POSSIBLE that climate change is having an effect, but none that say definitively that climate change is in fact causing reduced water levels. In fact, click on the footnotes highlighted in the article cited. All of them are from 2007 when in fact much of the Great Lakes water levels were in serious decline. The Daily Green says “the culprit COULD be… global warming.” The MSNBC article never says the Great Lakes are shrinking, it simply says that at that time in 2007 the water levels were a serious problem, which they were. And even more laughable is the citation of the USA Today article. Reading the article, you see this quote:
    “It’s been a long time since we’ve been this low, but it has happened,” says Tim Calappi, a hydraulic engineer for the Army Corps of Engineers, which tracks water levels. “We still think this is within the range of what’s normal, but we have to wait and see.”

    In fact, even with the title “Disappearing Lake,” here is what the article cites,
    “Many people living near Lake Superior don’t buy drought or warm weather as the reasons for dropping water levels — a conspiracy theory is more popular. They say Lake Superior was drained through the St. Mary’s River to raise the levels of Lake Huron and Lake Michigan.”

    Far cry from saying climate change is causing the Great Lakes to go away.

    Another factor is we’ve changed the drainage paths from the lakes – like connecting the Chicago rive out to the Mississippi drainage — so the rate od drainage of Michigan adn Superior with a new river draining themwould be expected to lower them even if rainfall stayed identicle.
