使用最先进的排放驱动的马克斯·普朗克研究所地球系统模型,我们探索了人工海洋碱化(AOA)的影响,并基于代表性浓度途径(RCP)框架。在RCP8.5排放下,向海洋表面添加114 Pmol碱度可将大气CO2浓度稳定在RCP4.5水平。这种情景从大气中去除940 GtC,并在本世纪内减轻1.5 K的全球变暖。气候适应了较低的二氧化碳浓度,防止海冰消失和海平面上升。海水pH值和碳酸盐饱和状态(Ω)大幅上升,高于当前十年的水平。预测了区域对AOA敏感性的显著差异,北冰洋和热带海洋将成为AOA引起的生态地球化学变化的热点。因此,AOA的CO2减排潜力是以前所未有的海洋生态地球化学扰动为代价的,其生态后果未知。
Using the state‐of‐the‐art emissions‐driven Max Planck Institute Earth system model, we explore the impacts of artificial ocean alkalinization (AOA) with a scenario based on the Representative Concentration Pathway (RCP) framework. Addition of 114 Pmol of alkalinity to the surface ocean stabilizes atmospheric CO2concentration to RCP4.5 levels under RCP8.5 emissions. This scenario removes 940 GtC from the atmosphere and mitigates 1.5 K of global warming within this century. The climate adjusts to the lower CO2concentration preventing the loss of sea ice and high sea level rise. Seawater pH and the carbonate saturation state (Ω) rise substantially above levels of the current decade. Pronounced differences in regional sensitivities to AOA are projected, with the Arctic Ocean and tropical oceans emerging as hot spots for biogeochemical changes induced by AOA. Thus, the CO2mitigation potential of AOA comes at a price of an unprecedented ocean biogeochemistry perturbation with unknown ecological consequences.
