Great Lakes Ice Cover Hits Historic Low, Threatening Shipping and Water Levels
CHICAGO — The Great Lakes, a critical artery for North American trade and water supply, have reached a record low ice coverage this winter, averaging just 3% in January. This dramatic reduction, driven by unseasonably warm temperatures, is now disrupting commercial shipping routes and raising urgent concerns about long-term water level declines. Industry analysts warn that the lack of ice cover will accelerate evaporation, potentially costing the regional economy billions in lost trade revenue and threatening municipal water access for millions.
