"Ice cover on North America’s Great Lakes reached almost
90% last month, the highest level observed in 20 years, and could break
the all-time record.
"Persistently low temperatures across the Great Lakes region are
responsible for the increased coverage of the ice," said Nathan Kurtz, a
scientist with Nasa."Low temperatures are also the dominant mechanism for thickening the ice, while secondary factors like clouds, snow, and wind also play a role."
USA Today quoted a scientist as saying that the record of 95% - set in February 1979 - could be broken." ...."Baltimore-Washington International Thurgood Marshall Airport broke a 141-year-old record low temperature for March, reaching 4F (-15C)."
