A heat wave that has stifled the southern tier of the U.S. for weeks has expanded into the Plains, Midwest and now the Mid-Atlantic and Northeast on Thursday, triggering heat alerts for over 227 million people, according to the National Weather Service.

    I heard you got 5 cubic miles of cold water… Sure would be a shame if that became 5 cubic miles of hot water.

      The lakes hold 5500 cubic miles of water, not 5. But yes, the lakes have been warming, surface temps on Superior are 2.5C hotter than they were 50 yrs ago. Which is alarming no doubt. The deep temps in Superior remain a constant 4C all year round and that temp seems to be pretty stable.

      We got lucky with the lake winds this week. That’s all.

      People who think climate change is going to spare this region are overstating the case by a lot. That said, I guess being on defense in the water wars will be better than being on offense… maybe?
