Early ice cover on Lake Superior bucks trends
The trend for nearly 30 years has been less ice cover on the big lake, with water temperatures rising.
A University of Minnesota-Duluth study found the lake's temperature has risen 4.9 degrees since 1979, about twice as fast as the rise in air temperatures in our area.
The Lake Superior water-temperature increase has been cited as one of the most pronounced examples of global warming anywhere on the planet.
