It is important that palaeoclimatologists continue to improve understanding of how the Earth responds to climate forcing, so that climate models can be rigorously validated and refined. Since the Earth responds to most of this forcing over time scales that exceed the length of instrumental weather measurements, the recovery of datable palaeoclimate archives that are highly sensitive to past climate changes is essential. Our project will provide important new palaeoclimate data from both hemispheres on how key regions of the Earth responded to past climate changes. This will bring improved understanding of past oceanic-atmospheric processes that can be fed into climate models, ultimately producing better forecasts to the benefit of all Australians.

重要的是，古气候学家继续提高对地球如何响应气候强迫的理解，以便气候模型能够得到严格的验证和改进。由于地球在超过仪器天气测量长度的时间尺度上对这种强迫的大部分做出反应，恢复对过去气候变化高度敏感的可测年古气候档案至关重要。我们的项目将提供来自两个半球的关于地球主要地区如何应对过去气候变化的重要的新的古气候数据。这将带来对过去海洋-大气过程的更好理解，这些过程可以被输入到气候模型中，最终产生更好的预测，使所有澳大利亚人受益。
