The lack of ice coverage present just days ago on the largest of the Great Lakes, Lake Superior. According to a report published last month in the Journal of Climate, the 5 percent of the Great Lakes' surface that froze over this year puts the average amount of ice covering the lakes at a decline of 71 percent over the past 40 winters, with Lake Superior's coverage alone declining a whopping 79 percent. The lead author of the report, Jia Wang, attributes the reduction to several factors including climate change and the more cyclical El Niño and La Niña climate patterns.
