An unusually warm winter has left the Great Lakes all but devoid of ice and sent scientists scrambling to understand the possible consequences as climate change accelerates.
Ice coverage on the lakes, which have a combined surface area roughly the size of the U.K., has generally peaked in mid-February over the last 50 years, with as much as 91% of the lakes covered at times, according to theGreat Lakes Ice Tracker website....
we had never seen ice coverage on the Great Lakes fall below 4.5 percent until this year. The previous all-time February low occurred in 2012 when ice extent across the five lakes failed to crack 10 percent all month.
The region comes alive during winter. But both culture and the economy suffer when the cold doesn’t come.
Lakes Superior, Huron and Erie are 80 to 90 percent covered. Ontario has by far the least ice coverage at just over 10 percent--down from a high of about 40-50 percent 10 days ago. The record ice coverage for all five lakes was set in 1979 at nearly 95 percent....
Guest Post By Just The Facts After Micheal Mann and Kevin Trenberth helpfully attributed the recent record snowfall in Boston to global warming, we now have another undeniable indication of alarming extreme runaway global warming. After last year's 2nd highest maximum in Great Lakes Ice Coverage;...
The presence/absence of ice cover and its seasonal growth also influence energy and heat exchanges between lakes and the overlying atmosphere. The poor spatial/temporal coverage of ground-based observations in most northern countries make remote sensing a desirable tool for investigating the response ...
Ice coverage in the Great Lakes has expanded greatly since New Year's Day. - Articles from The Weather Channel | weather.com
This season, ice coverage on the Great Lakes has exceeded all other measurements since 1979. During a typical winter, 30 to 40 percent of the Great Lakes are covered by ice. Usually arctic air swept over the Great Lakes creates lake-effect snow but modifies the air, making it warmer. ...
