随着全球气候变暖，格陵兰冰盖的加速融化引起了科学界的广泛关注。本研究重点探讨了格陵兰冰盖融水对北大西洋经向翻转环流（AMOC）的影响及其可能引发的全球气候系统的改变。本研究利用增强Kolmogorov–Smirnov (KS) 检验，识别不同气候记录中的气候突变点，并通过重建的8万年前冰盖变化结果与之进行对照检验。在此基础上，本研究讨论了现代二氧化碳与格陵兰冰盖融水变化之间的对应关系，进一步理解了两者与AMOC的可能联系。通过对格陵兰冰盖融水过程的历史和现代数据进行系统分析，并结合已有气候模拟结果，本文初步评估了格陵兰冰盖融水增加对AMOC活动的具体影响。我们认为，虽然已有研究结论表明格陵兰冰盖融水会导致北大西洋表层海水淡化，抑制北大西洋深层水形成，从而可能导致AMOC强度减弱，但由于地球系统的复杂性，格陵兰冰盖融水并不是导致AMOC变化的全部原因。本研究为理解全球变暖对极地冰盖-海洋-大气系统的影响提供了新视角，对深入理解未来极地气候和环境变化具有重要的科学意义。

With global warming, the accelerated melting of the Greenland ice sheet has attracted much attention from the scientific community. This study focuses on the influence of meltwater from the Greenland Ice Sheet on the North Atlantic Meridional overturning circulation (AMOC) and its possible changes in the global climate system. In this study, enhanced Kolmogorov-Smirnov (KS) tests were used to identify abrupt climate changes in different climate records and compare them with reconstructed ice sheet changes from 80,000 years ago. On this basis, this study discusses the correspondence between modern carbon dioxide and changes in Greenland ice Sheet meltwater, and further understands the possible connection between the two and AMOC. Based on a systematic analysis of historical and modern data on Greenland ice Sheet meltwater processes, combined with existing climate modeling results, the specific effects of increased Greenland ice sheet meltwater on AMOC activities are initially assessed. We believe that although some studies have concluded that meltwater from Greenland ice sheet will lead to the desalination of surface seawater in the North Atlantic Ocean and restrain the formation of deep water in the North Atlantic Ocean, which may lead to the weakening of AMOC intensity, due to the complexity of the Earth system, meltwater from Greenland ice sheet is not the whole reason for the change of AMOC. This study provides a new perspective for understanding the impact of global warming on the polar ice-ocean-atmosphere system, and has important scientific significance for in-depth understanding of future polar climate and environmental changes.
