Global warming to deplete Great Lakes even more

CHICAGO (Reuters) - Global warming will likely drain more water from the Great Lakes and pose added pollution threats to the region's vulnerable ecosystem, environmental groups said in a report issued on Wednesday.

Climate change could further reduce scant ice cover observed in recent winters, increasing evaporation rates and dropping water levels in the five lakes that collectively make up 20 percent of the world's surface fresh water.

Last year, Lake Superior water levels receded to their lowest in 77 years before rebounding, and the report by the Healing Our Waters-Great Lakes Coalition predicted global warming could lower lake levels by up to 3 feet (1 meter) over the next century.

The lower levels will hamper lake shipping, expose polluted sediments, and further damage water quality.

"Climate change is threatening the health of the Great Lakes and jeopardizing efforts to restore them," the coalition's Jeff Skelding said in a teleconference.

I strongly encourage those seriously interested in learning about the technology, players, politics, and issues of Wind Energy to spend time browsing the American Wind Energy Association website. They are the premier industry trade organization and have extensive resources available.

Why I Publish This Blog:

"One thing that many people do not realize is that states like Wisconsin, Illinois, Indiana,
and Michigan are sitting on a gold mine of wind energy potential. Or, more properly, next to the mine.
The Great Lakes are probably the area in the USA with the third largest inland wind energy potential.
Think of just the nickname for Chicago. "The Windy City". Milwaukee is even windier, I can tell you.
Why? Because they sit on the edge of a great flat area where there is both a land-water temperature
differential, and a large flat expanse of water that is comparably shallow.
Oilrigs certainly operate in deeper waters. And you won't have to construct transmission lines all the
way from the plains of Montana to put it to use.

The Great Lakes area has an opportunity to get the jump on wind energy's future, if that fact is
recognized and exploited. Wind energy means jobs for construction and maintenance workers, thousands
of them. Wind energy means leasing rights and extra money for family farmers struggling to make it on
agriculture alone. In most cases farmers can grow crops right up to the base of a windmill. The land
footprint has a small impact on total farm acreage. Wind energy also means freedom from fluctuating
fuel prices. Wind is free. The cost of a barrel of polluting oil can be raised or lowered drastically
based on fears or political whims. The potential gains are enormous. We've all seen the flow of good
manufacturing jobs out of the area. Well, they can't tell the wind to blow in another country so it's
more "convenient" or cheaper to produce. The wind is perfectly happy to whip up opportunities for us
right around here. Most of all, because we here in the Great Lakes region have the potential to have
a huge positive impact on U.S. energy industry emissions' contribution to global warming."
