AND because there was greater than average ice cover the previous two winters, leading to less water being lost to evaporation.
great lakes water levels are determined by a complex system of water in from the drainage basin, water out through the chicago river and the st. lawrence out-flows, and of course water lost to evaporation. and the amount of evaporation the lakes experience is very complicated to determine and varies wildly from year to year, hence why it's impossible for anyone to really say with any kind of certainty what the prospect of climate change means for the great lakes.
but one thing is certain, a 216' ocean rise would in no way shape or form directly correlate with a 216' rise in the great lakes. that's just straight-up nonsense.
that's literally not how any of this works.

It's uncertain how climate change will affect water levels in the Great Lakes, which already fluctuate periodically, the scientists said.
Warmer temperatures will produce less ice cover, boosting evaporation and pushing levels down.
However, they could rise in years with especially heavy precipitation and temporary deep freezes caused by southward migration of frigid polar air.

or in other words: no one really knows for certain what's gonna happen to great lakes water levels.
