A century worth of human innovation including the industrial revolution can wreck havoc to any environment that it comes into contact with. With leaps in scientific measurement we can now look at the world in completely new ways and a side effect of that is being able to look into the future with some certainty. Climate change is a hot topic along with its effects. The Great Lakes and global warming is a situation that will significantly change an entire region.

This area is already dealing with the deleterious affects of invasive species, and something like climate change will only act like fuel to a fire. Twenty percent of the world's fresh water comes from the Great Lakes, it is a major source of this finite resource and any depletion will have massive and widespread repercussions.

Spending time talking about how important the Great Lakes are cannot be cast aside. Drinking water, as important and essential it is, is not the only thing the lakes provide. The region gives a huge amount of hydroelectric power to surrounding areas and is a main waterway for shipping routes. In terms of nature, it is a hub for a number of plant and animal species.

All of the benefits come hand in hand with issues that result from extended urban development. These issues include pollution, air and water, as well as the invasion of a habitat by building. Because of the growth of the last century the great lakes are in a position to be easily affected by global warming. The smallest shift in temperature can have widespread repercussions.

Increasing temperature will melt the ice cover that, at this point, is already quite thin along the lakes. No cover will increase the overall evaporation of the lakes and decrease overall water levels.

Lake Superior was at its lowest levels in seventy seven years as recently as last year and the future could bring another meter of water loss. The effects of low water levels will impact shipping routes and will concentrate the pollutants left behind which will damage overall water quality.

At the present, there are preliminary measure being discussed to restore the grandeur to the Great Lakes, but it will require billions of dollars over a number of years. Updating antiquated sewage treatment systems and cleaning up the already polluted sediment will be coupled with a natural buildup of wetlands that will act as a natural filter and barrier from invasive species.

There are more repercussions from climate change other than decreasing water levels and that includes an increase in the number and ferocity of storms and drought periods. In response to these weather extremes viral transmissions can increase and pollution runoff may be increased. Within the lakes there may be more dead zones, places where there is no oxygen because of algae overgrowth.

The predicted future statistics are not encouraging. The temperature itself will be increased two to four degree centigrade with lake levels falling anywhere from 1.5 to 8 feet! Weather wise, the increase in storms may be 25%.

The future may seem to hold a number of destructive elements, but they can be tempered by being proactive in the present and working to make the Great Lakes as great as they once were.
