虽然上新世的温度和pCO2与IPPC RCP 4.5情景中预测的相似，但在此期间，珊瑚礁在最大珊瑚多样性中心珊瑚三角区的分布情况尚未得到探索。我们发现，在上新世，我们称之为上新世珊瑚礁间隙，珊瑚礁的出现率显着降低，但这种减少与珊瑚属丰富度的下降无关。虽然导致这种下降的一些多重当地原因，如海平面上升，与人类世珊瑚礁下降的驱动因素类似，但其中既没有变暖也没有增加pCO2。
Although Pliocene temperature and pCO2 are similar to those predicted in the IPPC RCP4.5 scenario, the distribution of coral reefs in the center of maximum coral diversity, the Coral Triangle, during this period has not been explored. We discovered a significantly lower occurrence of reefs during the Pliocene, which we refer to as the Pliocene Reef Gap, but this decrease was not associated with a drop in coral genus richness. While some of the multiple local causes that drove this decline, such as sea level rise, are analogs to drivers of Anthropocene reef decline, neither warming nor increasing pCO2 are among them.
