I agree with the conclusion of your Aug. 20 editorial "Great Lakes' waters steady." False alarms are counterproductive. How could anyone who's been watching the Arctic glaciers melt at alarming rates (see www.chasingice.com) conclude that the oceans will rise enough to affect even Lake Ontario, nearly 250 feet above sea level? New York City, of course, isn't so safe, as superstorm Sandy proved.
The Great Lakes watershed stops far to the south of those disappearing icecaps. In fact, drought and water level decline are a greater threat to the commerce and biology of our planet's largest chain of freshwater lakes. The U.S. Army Corps of Engineers reports Lake Michigan and Lake Huron are at their lowest water levels since recording began in 1918. And last summer's drought-induced fires and crop failures across mid-America set off more than a few alarms.
Alarm has its place. If nine of 10 oncologists are convinced your chain-smoking teenager has early signs of lung cancer, but their internist has doubts, I'd be alarmed if you didn't seek treatment.
