Around that time, Lake Superior was consistently at least 75 percent frozen over. Now, 75 percent coverage is rare, only happening about once every four years. Ice on the Great Lakes, and Lake Superior specifically, is a great way to measure climate for our region. MPR News chief meteorologist Paul Huttner spoke with UMD professor Jay Austin, about what ice coverage can tell us about climate change.
