Great Lakes Ice Coverage Reaches Record Low, Raising Alarm Among Scientists
WHO: Scientists and climatologists from the National Oceanic and Atmospheric Administration and the Great Lakes Environmental Research Laboratory.
WHAT: Maximum ice coverage across the Great Lakes has plummeted to a record low of just 2.5 percent, far below the historical average of 50 percent.
WHEN: This measurement was recorded during the peak of the winter season in mid-February, a period typically characterized by maximum ice formation.
WHERE: The entire Great Lakes basin, encompassing Lakes Superior, Michigan, Huron, Erie, and Ontario, all of which experienced unprecedented ice deficits.
WHY: Persistent warmer air temperatures and unseasonably warm lake surface temperatures, likely exacerbated by long-term climate change trends, prevented normal ice formation.
HOW: Satellite imagery and buoy data confirmed the historic low, indicating a lack of the usual ice cover that helps protect shorelines from erosion and supports regional ecosystems and winter tourism industries.
