University of Wisconsin Eau Claire Events

John J. Magnuson will present "What Does Lake Ice Seasonality Tell Us About Climate Change?" from noon-1 p.m. in the Blue Hills Lecture Hall (Ritzinger 234) on the UW Eau Claire Barron County campus. Magnuson is an aquatic ecologist and limnologist with a special interest in fish and fisheries ecology. He is now an emeritus professor at the University of Wisconsin-Madison, residing in the Center for Limnology which he helped form in 1982, and was its first director. He has a strong interest in seeing science used in solving real world issues related conservation of species, climate change, and fisheries.In Wisconsin and other states some records of “ice on” and “ice off” on many lakes began as early as the 1850s. What do these records tell us about what is happening with our climate (even before direct temperature measurements were taken)? Professor Magnuson will talk about the changes and variability in ice cover in Wisconsin lakes from the 1850s to the present, including the fact that several of our Wisconsin inland lakes have had one or more winters with incomplete ice cover. He will also discuss other global measurements. For instance, one long-term record in Japan comes from a Shinto ceremony on Lake Suwa that began before Columbus discovered America and another in Finland that began before the start of the Industrial Revolution. He will also discuss the value of lake ice to us for cultural reasons as well as a measure of what is happening to climate.Lecture attendees are welcome to bring their lunch to the presentation.______________________________________________ Thursdays @ the U lecture series will run throughout the spring semester. The series, partly funded by the UW-Barron County Foundation, will explore topics in the arts, sciences, public affairs, literary fields and cultural areas. While hosting a variety of speakers, the university does not seek to endorse or promote a particular idea, opinion, topic or product over others. These lectures are free and open to the public.

Location:
Blue Hills Lecture Hall (Room 234) located in Ritzinger Hall.
