Sea levels, sea surface temperatures and the variability of El Niño will be determined for previous warm interglacial periods using well dated, stratigraphically controlled fossil corals preserved in uplifted reefs. Relationships between past changes in sea level and warmer ocean temperatures will provide insights into the response of sea level to global warming. Knowledge of the frequency and amplitude of El Nino events that occurred during previous interglacial warm periods will provide a better understanding of processes controlling extreme events in the climate system.

将利用保存在隆起珊瑚礁中的年代久远、受地层控制的珊瑚化石来确定以前温暖间冰期的海平面、海面温度和厄尔尼诺现象的变化。过去海平面变化与海洋温度升高之间的关系将为了解海平面对全球变暖的反应提供帮助。了解前几次间冰期温暖时期发生的厄尔尼诺现象的频率和幅度，将有助于更好地了解气候系统中控制极端事件的过程。
