Ice builds up along a pier on Lake Michigan on February 18, 2024 in St. Joseph, Michigan. The Great Lakes shorelines have historically been ice-covered this time of year, but this winter's warm weather has led to the lowest ice cover over the lakes system since record keeping began in 1973. The loss of ice on the lakes is part of a decades-long trend which has seen the coverage drop by about 5% a year since the 1970s. (Photo by Scott Olson/Getty Images)
