Global Warming and the Great Lakes

Already, Lake Superior has increased water temperatures and an earlier onset of summer stratification by about two weeks in just the past 30 years. Within another 30 years Lake Superior may be mostly ice-free in a typical winter.

Lake Erie water levels, already below average, could drop 4-5 feet by the end of this century

Lake Superior obliterated all records for ice this year, and the water level in all of the Great Lakes is above normal.
