LANSING (WKZO) -- Conservationists are now concerned about the effects of climate change on the Great Lakes. Frank Szollosi, with the National Wildlife Federation's Great Lakes Region, says that rising water temperatures in the lakes are impacting the fish population.
Szollosi tells us, for example, that in Lake Superior, water temperatures have gone up by four degrees since 1980, and that's enable the invasive sea lamprey to grow in population.
A new report from the Wildlife Federation called "Swimming Upstream: Freshwater Fish in a Warming World" outlines the threats posed to the Great Lakes by climate change was released this month. The organization is calling for more action on protecting the native species of the lakes, in part to preserve Michigan's billion dollar angling industry.
