Andrew Smith:格陵兰岛是世界上最大的岛屿,也是丹麦的自治领土。大约有57000人居住在那里,主要居住在沿海地区。格陵兰岛大部分地区位于北极圈以北,覆盖着厚厚的冰层。格陵兰岛在数十亿人每天经历的天气和全球气候变化中扮演着重要角色。美国候任总统唐纳德·特朗普表达了从丹麦购买格陵兰岛的兴趣。他也在他的第一任期内说过类似的话,美国在该岛上有一个大型军事基地。地质学家说,格陵兰岛的冰层下蕴藏着大量的石油和天然气,以及被称为稀土矿物的宝贵元素。稀土矿物在通信技术(包括手机)中是必需的。这些资源大部分都被困在格陵兰岛的冰层下。然而,近年来气温变暖增加了该岛的融化。随着更多冰的融化,这些资源可能更容易获得。格陵兰岛位于加拿大北部、欧洲北部和俄罗斯之间。如果北冰洋的融化继续增加,并且有更多船只通过该地区,那么该地区对各国来说可能会更有价值。 Jeff DeBelko:我认为其他国家开始对格陵兰岛感兴趣,是因为中国目前是全球一半以上稀土矿物的供应国。 Mark Cerise:从1992年到2020年,格陵兰岛每年平均损失1690亿公吨冰,2019年损失达到4440亿公吨。格陵兰岛的融冰将是21世纪的核心问题,因为融化的冰增加了海平面上升。融化的数量未来可能会增加。格陵兰岛融冰导致大西洋经向翻转环流减缓,这可能导致欧洲和北美部分地区长期冻结。 Jennifer Francis:随着更多冰的融化,格陵兰岛的颜色也从冰的白色变为水和土地的蓝色和绿色。这些较暗的颜色吸收更多来自太阳的热量,并可能加快变暖速度。

Chapters
This chapter explores the significant role of Greenland's melting ice in global climate change, rising sea levels, and the impact on ocean currents. It also discusses the geopolitical interest in Greenland due to its potential resources and strategic location.
  • Greenland's melting ice contributes to rising sea levels and impacts ocean currents like the AMOC.
  • The melting reveals potential resources like rare earth minerals and oil, attracting international interest.
  • Greenland's strategic location between North America, Europe, and Russia is becoming increasingly important due to Arctic melting.
