George Leshkevich, a NOAA expert on Great Lakes ice, suggested in an interview that he wouldn’t be surprised if there was ice on Lake Superior in June.
While satellite images show more ice broken up and in smaller floes, there’s “a lot still on the lake,” Leshkevich said.
He said ice on the lake this year compares to 1979 in terms of coverage, with about 67 percent iced over on the comparable date of April 23.
He’s still running the numbers, but 2014 looks like “there’s going to be even more” lingering ice than in 1979. “This year is maybe a record-breaking year.”
The unusually high level of ice cover on the Great Lakes, no doubt caused by global warming, has been causing significant difficulties for local shipping.
