Rising and falling: theme of summer

July 18, 2014

The summer of 2014 will be remembered as one filled with rises and falls. The sluggish ability of the thermometer's rise last winter resulted in a nearly complete cover of ice on Lake Superior. Lasting for much of the winter, the ice prevented much water from evaporating. It does seem hard to think of evaporation of lake water in winter, but simply picture the open lake on a subzero morning in January with the "fog" rising up and it is easier to picture water escaping. Paired with the spring's melting pattern and some precipitation, Lake Superior's level is up nearly 13 inches from last year.
