The average annual ice coverage for the Great Lakes during 2003-2013 was less than 43% of the coverage over the prior half-century, lower than any other decade during the period of measurement. Less ice, together with more frequent and intense storms, leaves shoreline vulnerable to increased risk of erosion and flooding.
