Cornell University recently did this with the deep water of Cayuga Lake (http://www.worldchanging.com/archives/000839.html ). As you can imagine, it caused quite a spirited debate in such a liberal town as Ithaca. In the end it was approved and the University is gauging the environmental effects very carefully(http://www.town.ithaca.ny.us/PEZ%20proje cts/Lake%20Source%20Cooling/lake_source_cooling_mo nitoring_p.htm). So far, there's been little effect. Although some (http://www.cldf.org/tt_981216/chap1.html) might disagree. I would like to point out to the concept's cheerleaders that there's nothing wrong with asking questions about the fundamental ecological effects of our engineering projects. Those questions should be answered thoroughly and carefully. Yes, global warming appears to be a severe problem, however let's not replace it with a bigger problem by stifling debate and rushing in with an ABCO2 (Anything But Carbon diOxide) attitude that might be more harmful than the disease.
