热带珊瑚礁系统正在过渡到一个新时代，珊瑚白化反复发作之间的间隔太短，无法完全恢复成熟的组合。我们分析了 1980 年至 2016 年间全球分布的 100 个珊瑚礁地点的白化记录。自 1980 年以来，两次严重白化事件之间的平均重现时间一直在稳步缩短，现在仅为 6 年。随着全球变暖的进展，当前拉尼娜现象下的热带海洋表面温度比三十年前的厄尔尼诺事件期间要高。因此，当我们过渡到人类世时，珊瑚白化在厄尔尼诺-南方涛动的所有阶段都会更加频繁地发生，从而增加了未来几十年每年发生白化的可能性。
Tropical reef systems are transitioning to a new era in which the interval between recurrent bouts of coral bleaching is too short for a full recovery of mature assemblages. We analyzed bleaching records at 100 globally distributed reef locations from 1980 to 2016. The median return time between pairs of severe bleaching events has diminished steadily since 1980 and is now only 6 years. As global warming has progressed, tropical sea surface temperatures are warmer now during current La Nina conditions than they were during El Nino events three decades ago. Consequently, as we transition to the Anthropocene, coral bleaching is occurring more frequently in all El Nino-Southern Oscillation phases, increasing the likelihood of annual bleaching in the coming decades.
