深海吸收了大量的热量和二氧化碳,是应对气候变化的重要缓冲,但在水温升高、海洋酸化、脱氧作用和粮食投入改变的联合压力下,海洋的生态系统十分脆弱。由此引起的变化可能会威胁到海洋的生物多样性,危害海洋的关键功能,不利于保持健康的地球生态和人类生活。目前,针对将发生的深海物理和生态反馈的理解还远远不够。明确承认深海能减缓气候变化并将其纳入联合国气候变化框架公约(UNFCCC)的规划,有助于发展深海研究和观测,保护深海生态系统的完整性和功能。
Deep sea absorption of large amounts of heat and carbon dioxide is an important buffer against climate change, but under the combined pressure of rising water temperatures, ocean acidification, deoxidation and food inputs, marine ecosystems are vulnerable. The resulting changes may threaten the biological diversity of the oceans, endanger the key functions of the oceans and the detriment of maintaining a healthy earth ecology and human life. At the moment, understanding of deep-sea physics and ecological feedback that will take place is far from enough. Clear recognition that the deep ocean can mitigate climate change and incorporate it into the UN Framework Convention on Climate Change (UNFCCC) programs helps to develop deep-sea research and observations and protect the integrity and functioning of deep-sea ecosystems.
