科学家利用历史温度重建了大湖地区120年的冰覆盖,揭示了变暖趋势和较短的霜冻季节。 Scientists reconstructed 120 years of Great Lakes ice cover using historical temperatures, revealing warming trends and shorter frost seasons.

研究人员利用1897年的历史温度数据,重建了大湖区长达120年的冰覆盖记录,填补了气候记录中的一个重大空白。 Researchers have reconstructed a 120-year record of ice cover on the Great Lakes using historical temperature data from 1897, filling a critical gap in climate records. 通过将空气温度与冰层形成挂钩,数据集使科学家能够研究冬季生态、气候变化影响和冰层安全的长期趋势。 By linking air temperature to ice formation, the dataset enables scientists to study long-term trends in winter ecology, climate change impacts, and safety on ice. 尽管年复一年的变异性,包括最近创纪录的低温和异常高的冰覆盖率,但冰季较短,天气更极端,呈现出升温趋势。 It reveals a warming trend with shorter frost seasons and more extreme weather, despite year-to-year variability, including recent record lows and unusually high ice coverage. 这些数据支持白鱼等物种的研究,并帮助社区为该区域未来环境变化做好准备。 The data supports research on species like whitefish and helps communities prepare for future environmental changes in the region.
