>>"The bottom line, the researchers concluded, was climate change: "Lake Superior is responding to global climate shifts as clearly as anywhere on Earth.""<<
As far as I am concerned, this is a stretch to extrapolate global warming from shallow water warm ups.
What about the fact that water levels have been low, and most of the watershed has been in a drought? Ontario side of the big lake had a total lack of snow cover and many of the trails had such little snow that they didn't bother to groom. Think that this might enfluence the "warming"??
Do you think that low water flow could warm up nicely from the streams and rivers which flow into the big lake causing the big lake that lives off of these streams and rivers, to warm too?
What affect does that low flow-age have on currents? What about the amount of sunlight hitting the water compared to number of cloudy days?
I can think of at least a dozen things that could influence these "superficial" findings.
And it may well be a globalized warming that is contributing to this; call me a doubting Thomas here, but I am going to need a whole lot more research before I go around supporting this "sky is falling" theory.
