Collaborative Research: Investigation of Climate Warmth andClimate Change in the Early Eocene

地球历史上的始新世时期比较温暖， 两极到赤道的温度梯度比现在大。初步 模拟结果表明，实现这种类型的唯一方法 是大气中二氧化碳浓度的增加 并且具有更高的向极热传输。 因此，这段时间， 地球的历史可能提供重要的限制， 未来大气中的二氧化碳会增加。 该提案要求 支持限制更高的CO2和热量传输的影响 利用复杂的大气环流模式 实验和新的古气候数据。 本研究是 这很重要，因为它将有助于隔离 高二氧化碳对气候的影响，这是一个非常重要的话题， 了解化石燃料二氧化碳对未来气候的影响。

The Eocene period of earth history was warmer and had lower pole-to-equator thermal gradients than today. Preliminary modeling results suggest that the only way to achieve this type of climate is with greater CO2 concentrations in the atmosphere and with higher poleward heat transport. Thus this interval in earth history may provide important constraints on the effects of future CO2 increases in the atmosphere. This proposal requests support to constrain the effects of higher CO2 and heat transport on this climate using sophisticated General Circulation Model experiments and new paleoclimate data. This research is important because it will help to isolate the effects of higher CO2 on climate, a topic which is very important for understanding the effects of fossil fuel CO2 on future climate.
