在过去的几年里，在理解末次冰期气候变化背后的机制方面取得了重大进展。通过开发一种新的中等复杂性的气候模型，这已经成为可能。在这篇评论中，这些模式的发展背后的哲学进行了讨论，特别注意到Uvic地球系统气候模式。然后调查结果，从众多的研究使用这些中间复杂性，以及其他，气候模型，旨在拼凑埋藏在古代理记录之谜。特别注意的是，在116，000年前的冰川初期所涉及的气候反馈，以及旨在了解千年时间尺度的Dansgaard-Oeschger振荡及其包装到债券周期在寒冷的气候，他们与海因里希事件的关联，以及他们对平均气候状态的依赖建模工作。在研究过去135，000年的气候时，拉布拉多海和南极绕极流中间沃茨形成的变化显然对气候系统的稳定性和可变性具有重要影响。还讨论了气候和古气候界未来面临的一些挑战。
Over the last few years significant advances have been made towards understanding the mechanisms behind climate variability over the Last Glacial Cycle. This has become possible through the development of a new breed of climate models of intermediate complexity. In this review, the philosophy behind the development of these models is discussed with particular attention given to the Uvic Earth System Climate Model. Results are then surveyed from numerous studies using these intermediate complexity, as well as other, climate models aimed at piecing together puzzles buried within the paleo proxy record. Particular attention is given to the climate feedbacks involved in glacial inception 116,000 years ago, as well as modelling efforts aimed at understanding millennial timescale Dansgaard-Oeschger oscillations and their packaging into Bond Cycles in cold climates, their association with Heinrich events, and their dependence on the mean climatic state. In examining the climate over the last 135,000 years, it is apparent that variations in the formation of intermediate waters, both in the Labrador Sea and the Antarctic Circumpolar Current, have important consequences for the stability and variability of the climate system. A discussion of some future challenges for the climate and paleoclimate community is also given.
