This project intends to improve our understanding of interglacial processes. Interglacials, the relatively brief warm intervals of Quaternary ice-age cycles, have varied significantly over the last 800 000 years in terms of their duration, timing, intensity and complexity. The reason for such diversity has eluded palaeoclimatologists for decades. This is because of the difficulty of dating marine and ice records, which best preserve interglacial histories. The projects plans to compile precisely dated time series of past interglacials that can be linked directly to these records, allowing robust comparisons between interglacial properties and changes in Earth's astronomical parameters. This would advance palaeoclimate theory and provide a new perspective on the future evolution of the climate system.

该项目旨在提高我们对间冰期过程的理解。间冰期是第四纪冰期周期中相对短暂的温暖间隔，在过去80万年中，其持续时间、时间、强度和复杂性发生了显著变化。几十年来，古气候学家一直无法解释这种多样性的原因。这是因为海洋和冰川记录的年代测定非常困难，而海洋和冰川记录最能保存间冰期的历史。这些项目计划汇编过去间冰期的精确日期时间序列，这些时间序列可以直接与这些记录联系起来，从而可以在间冰期属性和地球天文参数变化之间进行可靠的比较。这将推进古气候理论，并为气候系统的未来演变提供新的视角。
