明尼苏达州的湖冰覆盖面积在50年中下降了10至14天,因为冬季比较暖和。 Minnesota's lake ice cover has declined by 10 to 14 days over 50 years due to warmer winters.

在过去50年中,明尼苏达湖的冰盖减少了10至14天,冰层后来形成,较早融化。 Minnesota lakes have seen ice cover decline by 10 to 14 days over the past 50 years, with ice forming later and melting earlier. 温冬,特别是自1970年以来杜卢斯的温度上升6.4度,是促成因素。 Warmer winters, particularly a 6.4-degree increase in Duluth since 1970, are contributing factors. 这种变化可能导致更多的湖效应雪、更温暖的水温和有害的藻类开花。 This change could lead to more lake-effect snow, warmer water temperatures, and harmful algae blooms. 研究人员开始研究这些影响,并吸收社会科学家来理解社会影响。 Researchers are beginning to study the impacts and include social scientists to understand societal effects.
