This resource tells the story of how climate change is affecting ice cover on lakes in Wisconsin. Students will understand at the end of the lesson that shorter ice cover seasons are having a profound impact on the lakes in Madison, WI. The website provides an overview and context for the use of the data. The data presented show a record of ice cover days on two lakes near Madison, WI, since 1855. Although there is significant annual variation in the data, the overall trend established is evidence that climate change is happening now. Reduced ice cover has a significant ecological impact since it regulates lake temperature, dissolved organic (DO) levels, light penetration, and other factors responsible for the growth and reproduction of species present in and around the lakes.
