The Great Lakes is one of the most underappreciated bodies of water especially since it is the largest fresh water system on Earth and nearly 33 million people rely on it. In the past several thousand years there have been a few noticed incidents of varying water levels. This sparked the interest of scientists to figure out the reasons for the up and down change, even if it was only by a few meters. Here is when they realized a pattern and that the Great Lakes water level had dropped deeper than they had originally thought.
According to the Science Daily, the climate changes near the Great Lakes are clear warnings for the lowering water level. “The climate and water levels in the Great Lakes region are determined by the interplay of three air masses: dry, cold Arctic air from the North, dry warm Pacific air from the West, and warm, moist tropical air from the Gulf of Mexico.” Moreover, Scientists made an interesting discovery from this. They noticed that when the lake water levels decreased, there was a majority of dry air and when there was frequent precipitation, they would begin to flow normally from one another. On the other hand, Discovery News scientists believe that the real scientific reasoning is a major drop off in rainfall.
Now, although this problem may not seem that important, it can have drastic impacts on the lives of people relying on and living in the Great Lake region. Altering the stability of the Great Lakes starts to have an effect on a number of things. The depleting water levels can begin to cause an economic problem by means of delaying overwater shipment industries and hydropower plants and their strategies. Additionally, the evaporating water would change the original chemistry of the lakes, giving it a higher percentage of concentrated salt which defeats its uniqueness.
