Analysis of several buoys [Lake Superior is a big lake.  Can you really analyze "several" buoys and form conclusions about the heat content of the entire volume of water in that lake?] that measure temperatures in the lake reveal that the waters are some 15 degrees warmer than they would normally be at this time of year, Jay Austin, a professor of physics at the University of Minnesota, Duluth's Large Lakes Observatory, said in a recent interview.
