摘 要
本文深入探讨了全球变暖背景下极地冰盖融化对海平面上升产生的深远影响。文章开篇即分析了全球变暖如何显著影响极地温度，这一变化直接关联到极地冰盖的稳定性。随后，详细阐述了格陵兰冰盖与南极冰盖的融化特征，包括融化速度、范围及其对全球气候系统的反馈作用。基于丰富的观测数据，本文进一步评估了冰盖融化对海平面上升的贡献度，明确指出冰盖融化是当前海平面上升的主要驱动力之一。同时，文章还揭示了不同区域海平面变化的差异性，强调了地理因素对海平面上升影响的复杂性。为更准确地预测未来海平面上升的趋势，文章构建了气候变化情景下的海平面上升预测模型，并对沿海地区进行了全面的风险评估。基于评估结果，本文提出了针对性的适应与减缓措施建议，旨在帮助沿海地区有效应对全球变暖带来的挑战。

ABSTRACT
This article delves into the profound impact of polar ice sheet melting on sea level rise in the context of global warming. The article begins by analyzing how global warming significantly affects polar temperatures, which is directly related to the stability of polar ice caps. Subsequently, the melting characteristics of the Greenland ice sheet and the Antarctic ice sheet were elaborated in detail, including melting rate, range, and their feedback effects on the global climate system. Based on rich observational data, this article further evaluates the contribution of ice sheet melting to sea level rise, and clearly points out that ice sheet melting is one of the main driving forces of current sea level rise. At the same time, the article also reveals the differences in sea level changes in different regions, emphasizing the complexity of the impact of geographical factors on sea level rise. To more accurately predict the trend of future sea level rise, the article constructed a sea level rise prediction model under climate change scenarios and conducted a comprehensive risk assessment of coastal areas. Based on the evaluation results, this article proposes targeted adaptation and mitigation measures aimed at helping coastal areas effectively cope with the challenges brought by global warming.
