This free, in-person event will take place on October 16, 2024, at 12:00 PM at First English Lutheran Church in Appleton, WI. Registration is not required. Join the Noon Hour Philosophers, a group of history and philosophy enthusiasts, as they welcome fascinating speakers from the community, arts, and government. Free coffee will be provided.Lake ice cover provides a clear indicator of climate change and variability. Because human observers have recorded the dates of ice on and ice off on many lakes around the world, lake ice provides a view of what is happening, often well before direct climate measurements of temperature were available. In Wisconsin and other states some records began as early as the 1850s. So what do these records tell us? Professor Magnuson will talk about the changes and variability in ice cover in Wisconsin lakes from the 1850s to the present. Several of our Wisconsin inland lakes now have had one or more winters with incomplete ice cover. 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 largely for cultural reasons and as a measure of what is happening to climate.
Presenter John J. Magnuson is an aquatic ecologist and limnologist with a special interest in fish and fisheries ecology. His training is in fish and wildlife management, zoology, and oceanography. Current interests include: long-term ecological research on lake ecosystems, analyses of long-term lake ice time series, climate change impacts and adaptations, thermal ecology of fishes, landscape and invasion ecology of lakes.
Dr. Magnuson 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. His students have received their graduate degrees in Zoology, Oceanography and Limnology, and Water Resources Management. He has had a strong interest in seeing science used in solving real world issues related conservation of species, climate change, and fisheries.
