Not the Great Lakes!

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.

  1. The Great Lakes are definitely overlooked when people are looking at the impacts that the climate change is having on other things. However we should try to do something about it now, rather than wait for it to get as drastic as the others, and/or irreversible. People recommended that we start to restore the Great Lakes, which would cost $20 billion in five years. Though costly, it would be very beneficial for the economy in the long run, preventing the potential economic harm that is happening.

  2. I completely agree with your statement on how the Great Lakes are very under appreciated. They provide a sustainable way of life for millions of people and without them the world’s population would suffer greatly. It’s so important for us to take care of these lakes before it becomes too late to make a difference. The biggest problem, to me, is the fact that the Great Lakes are tied to so many different things. If the Great Lakes collapse it would create a huge domino-like chain reaction, which is why taking care of them should be a big priority.

  3. I read article about falling Great Lake water level and it make negative effect in Michigan ecosystem and industries. It looks not significant physically; however, its effect is very significant. The reason is climate change from global warming. To prevent this, people should know about greenhouse effect and how to reduce greenhouse gases through education. In addition, state government also prepare regulation of emitting CO2 to industries. It is hard way; but, people should do it!
