Context (DTE): For the second consecutive year, the Great Lakes, Earth’s largest freshwater ecosystem, have experienced historically low ice levels.
Above-average temperatures and reduced Arctic air blasts contribute to diminishing ice cover.
Great Lakes of North America are a series of large interconnected freshwater lakes in North America that connect to the Atlantic Ocean via the Saint Lawrence River.

The five lakes are Superior, Michigan, Huron, Erie, and Ontario, and they are generally on or near the Canada–United States border.
Hydrologically, Michigan and Huron are a single body of water joined at the Straits of Mackinac.
The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world’s surface freshwater by volume.
Because of their sea-like characteristics, such as rolling waves, sustained winds, strong currents, great depths, and distant horizons, the five Great Lakes have long been called inland seas.
Lake Michigan is the largest lake in the entire country.
