Badger Talk - Eagle: "What does lake ice seasonality tell us about climate change?"

Lake ice cover provides an 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.
