Similarly, Lake Superior lagged behind Lake Michigan by one-half. There was no change for Lake Michigan from 2000 to 2005; however, in 2010, it decreased by 0.5%. In 2015, the rate for surface covered by ice significantly increased and reached above four-fifths.
Lake Superior increased by one-tenth in 2005. Meanwhile, it again decreased by two-fifths. However, in 2015, Lake Superior had the highest lake surface covered by ice, which was 93%. There was no change for Lake Erie in 2005. However, it increased by 2% in 2010 but again decreased by 2% and reached 90%. However, in 2015, these lakes showed a downward trend and reached two-fifths of their 2000 levels.However, Lake Erie was in the highest position in 2020 at 40%.
