Frequent question: How will the Great Lakes be affected by climate change?

Are the Great Lakes getting warmer?

Climate change impacts

All the Great Lakes are warming, but Lake Superior stands out. Still the coldest lake, its summer surface water temperatures increased 2.5 C between 1979 and 2006, even faster than air temperatures. Even the deep waters of Lake Michigan are warming at a rate of 0.5 C per decade.

Will the Great Lakes flood with climate change?

How much will the Great Lakes rise with global warming?

The Great Lakes Integrated Sciences and Assessments, a NOAA-funded center in Ann Arbor, projects that Great Lakes states’ temperatures will increase by 3.6 to 11.2 degrees by 2100. Warmer weather is producing more atmospheric moisture in the region.

What would happen if the great lakes dried up?

Partially would close off shipping without radically redone locks and dredging, including pumped up from lakes or extensive aqueducts. In short, there would be period of massive economic loss. The relatively young Great Lakes apparently have in the past, but only to a limited degree.
