Diminished surface ice is just the beginning: Climate change is warming Lake Michigan and other big lakes all the way down to their chilly depths, according to new federal research.

In a first-of-its kind study, scientists with the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory have used the only known long-term dataset of deep-lake temperatures to determine that Lake Michigan’s temperature is slowly increasing over the past 30 years.

The Great Lakes go up and down. It's just a fact of life. 

Water levels in Lakes Superior, Michigan and Huron continue to be above their monthly averages for the first time in 16 years.

Scientists are working to identify a cyanobacteria bloom near the Maumee River. It's a yearly event that occurs during the warm summer months.

Researchers at the Great Lakes Environmental Research Laboratory confirmed that the cyanobacteria bloom has been intensifying over the last week.

Also known as blue-green algae, it can be harmful to the aquatic environment and to people. People shouldn't swim in a bloom- it can cause skin rashes or even severe stomach problems.
