CLIMATE CHANGE WARMING LAKE MICHIGAN AND OTHER WISCONSIN WATERS

Renowned limnologist John J. Magnuson will visit Milwaukee to discuss how loss of lake ice is a miner's canary of how rapidly global warming is occurring. 

He will address "Climate Change and the Waters of Wisconsin" at 7 p.m. Monday, June 11, in the Digital Theater of Discovery World at Pier Wisconsin, 500 North Harbor Drive, on Milwaukee's lakefront. Underground parking at Discovery World is available for $5. 
      
Magnuson, Professor Emeritus at UW-Madison, spent a decade building a database of ice records from all over the world, and it is now one of the largest and longest records of observable climate data ever assembled. Here in Wisconsin, these records show that over the last 30 years the duration of ice cover on Dane County's Lake Mendota decreased 8.6 days per decade. 
      
According to Magnuson, shorter periods of ice cover can increase evaporation, which would contribute to lower water levels on the Great Lakes and elsewhere. He says that the "typical" Wisconsin winter is disappearing, along with the recreational activities and businesses that depend on it. 
      
Magnuson also notes that warmer waters will affect fish that only live within specific temperature ranges. Streams and shallow lakes are likely to have reductions of coldwater and cool water habitat. And while the Great Lakes will continue to provide cold, oxygenated habitats for trout and salmon, he said many new species will invade to occupy the warmer inshore waters. 
      
Magnuson's lecture is part of the 2007 seminar series "Climate Change in the Great Lakes Region: Starting a Public Discussion," sponsored by the UW Sea Grant Institute and funded by the Wisconsin Coastal Management Program and the National Oceanic and Atmospheric Administration.
