这一发现将推动学界重新审视古今气候系统的关联机制，进一步完善古今气候对比研究的理论框 架。该团队介绍，过去学界普遍认为，当前气候及环流变化与约13万年前的末次间冰期暖期具有相似幅 度，而本研究打破了这一传统认知。研究揭示，二者差异源于地球绕太阳运行轨道变化带来的太阳辐射 量差异：13万年前的末次间冰期暖期，地球轨道偏心率与岁差同步达到峰值，显著改变了驱动南极绕极 流的西风强度与分布。 记者近日从海南大学获悉，该校海洋碳氮循环与全球变化团队研究发现，在约13万年前的末次间冰 期暖期，南极绕极流南部边界流速达现代流速的3倍，整体南移超5个纬度，这一变化直接导致南极冰盖 消融加剧。相关研究成果近日发表于《自然·通讯》。 结合当前及未来地球轨道偏心率与岁差均呈低值且持续下降的趋势，研究人员进一步提出，未来南 极绕极流或向北移动，有望抵消气候变暖引发的南移趋势，为精准预测未来全球气候变化提供了关键基 准。 研究团队依托国际大洋发现计划（IODP）382航次，通过美国"决心号"科学钻探船，在南极斯科舍 海3000—4000米深海钻取沉积岩芯，创新采用分选粉砂粒径分析法，重建了末次间冰期南极绕极流的动 态演变历史。在洋流沉 ...
