Our Changing World presentation March 14 at to look at climate change, lake temperatures

March 2, 2018

The impact of climate change on lakes both small and large will be the topic of an Our Changing World presentation from 6:30 p.m. to 8 p.m. Wednesday, March 14, in the Nicolet College Theatre.

“Recent studies have shown rapid warming of inland water bodies around the world,” said presenter John Lenters, honorary fellow at the University of Wisconsin-Madison Center for Limnology.

“Many lakes are warming more rapidly than air temperature, including small lakes in northern Wisconsin and quite a few large, deep lakes. This is contrary to what is usually expected.”

Lenters will discuss the variety of reasons that have been proposed to explain rapid lake warming. Lake Superior will be used as a case study to illustrate the “perfect storm” of factors that has caused a large, deep lake to warm at a rate that is more than three times the global average.

Lenters has a Ph.D. in atmospheric science from Cornell University and conducts postdoctoral research in lake-climate studies at the Center for Limnology and Center for Climatic Research at the University of Wisconsin-Madison.

His research focuses on the physical interactions between lakes and climate, with a particular interest in lake evaporation, temperature, ice cover, and water levels. His field studies have included the North American Great Lakes, thermokarst lakes in northern Alaska, saline lakes in western Nebraska, and temperate lakes in Wisconsin and Michigan. He is currently the lead investigator of the Global Lake Temperature Collaboration and a founding member of the Great Lakes Evaporation Network.

The Our Changing World Series is sponsored by the Oneida and Vilas County Chapter of the Citizen’s Climate Lobby and the Nicolet College Sustainability Professional Learning Community.

Other upcoming presentations in the series will include Projecting Climate Change Impacts on the Natural Resources of Wisconsin's Northern Highlands on Wednesday, April 11, and the Effects of Climate Change on Fish and Fisheries in the Northwoods on Wednesday, May 23.

All presentations are free and open to the public.
