Study predicts less severe Great Lakes water loss


TRAVERSE CITY, Mich. (AP) -- New research suggests climate change might not cause Great Lakes water levels to drop as much as previous studies have indicated. In fact, it might even cause them to rise.

Scientists at the NOAA Great Lakes Environmental Research Laboratory in Ann Arbor say they've devised a new way to predict future water levels. In a newly published journal article, they say it involves different methods of measuring evaporation of water from the soil and plants within the Great Lakes watershed.

Earlier studies based projections about evaporation only on air temperature. The NOAA researchers used additional factors that indicate less water than previously believed will be converted into vapor.

Low water levels can cause heavy losses for shippers and other Great Lakes businesses. They also affect the environment.
