Lake Huron is in a fog, part of a gloomy cycle that's pushing water levels to record lows, scientists say.
Last week, a winter storm dropped more than a foot of snow over the Great Lakes. Over the weekend, warmer temperatures melted that snow, and much of that water evaporated into the air.
The cycle has been playing out for the past 30 years in the Great Lakes, said Cynthia Sellinger, co-author of a paper to be published Tuesday in Environmental Science & Technology, a scientific journal.
