Great Lakes and Climate Change
Scientists have long assumed that the Great Lakes have been connected since their formation 16,000 years ago during the retreat of the last ice sheet, but recent evidence has found this to be false. Ancient shorelines, submerged beaches, and tree stumps on the floor of some lakes indicate that the water line had been as much as 20 meters below the present lake level. The levels dropped after dry air dominated the area from the Pacific and Arctic. Learn more about climate change and the Great Lakes, below.
