Scientists: Lake Erie Getting Warmer, Water Levels Dropping

CLEVELAND (AP) - Lake Erie continues to get warmer and water levels continue to drop.

And while the lake is much healthier than it was 20 years ago, it's still attracting the attention of scientists who worry that Lake Erie will go back to its unhealthy ways.

Robert Heath, head of the Water Resources Research Institute at Kent State University, says the average water temperature of Lake Erie has increased by about three-fourths of a degree over the last two decades.

He says climate models predict further increases in air and lake water temperature.

National Wildlife Federation staff scientist Michael Murray says warmer, shallower water would allow toxins to survive and would allow more invasive species to thrive.
