美国伍兹霍尔海洋研究所的最新研究显示，持续了约400年的印度洋与太平洋气候耦合关系正在被破坏1。研究人员通过分析可追溯至17世纪早期的古气候记录和气候模型模拟发现，这一长期存在的气候联系如今正面临前所未有的变化1。
历史上，火山喷发曾对这一气候联系产生过干扰。在1810年至1850年期间，一系列大型热带火山喷发导致太平洋对印度洋气候的通常影响暂时减弱1。然而，当前由人类活动引发的全球变暖正在驱动一种更为异常的关系破裂1。研究人员指出，"全球变暖和人类排放现在压倒了太平洋对印度洋的自然影响"1。自1980年代以来，科学家已注意到这种关系呈现减弱趋势1。该研究已于2026年9月13日发表在《自然通讯》杂志第17卷第1期1。
A long-standing climate relationship between the Indian and Pacific Oceans that has persisted for approximately 400 years is now unraveling due to human-induced global warming, according to research from the Woods Hole Oceanographic Institution. 1 Scientists analyzing paleoclimate records and climate model simulations traced this connection back to the early 17th century, revealing how a series of major tropical volcanic eruptions between 1810 and 1850 temporarily weakened the Pacific's typical climate influence on the Indian Ocean. 1
However, the current trajectory differs markedly from past natural disruptions. Researchers stated that "global warming and human emissions now overwhelm the natural influence of the Pacific on the Indian Ocean." 1 Since the 1980s, scientists have observed the steady deterioration of this relationship, marking a shift driven by anthropogenic factors rather than volcanic activity. 1 The findings were published in Nature Communications on September 13, 2026, in Volume 17, Issue 1. 1
