Global warming: 80 percent of Great Lakes covered in ice

Lake Michigan last month

Global warming is causing the Great Lakes to further ice-up.

From CBS Chicago:

The long deep freeze across the Upper Midwest this winter has left a whopping 80 percent of the Great Lakes covered in ice.

Data from the Great Lakes Environmental Research Laboratory, shows that more than half of Lake Michigan (54 percent) is on ice.

Neither number is a record, but those percentages are much higher than normal for the winter. Among the other Great Lakes, Lake Erie is nearly a full skating rink (94 percent), followed by Superior (93 percent); Huron (89 percent) and Ontario (38 percent).

The record Great Lakes ice-covering is 94 percent, set in the legendary winter of 1979.
