Abrupt warming and cooling events were a persistent feature of Earth's most recent climate cycle. Surprisingly, little is known of how these events affected the climate of Australia. This project will produce precisely dated reconstructions of rainfall and temperature trends in southern Australia during these events. These new terrestrial and ocean data will be compared with model simulations to determine how rapidly abrupt climate perturbations in the Northern Hemisphere reached our region, and the processes by which this occurred. The results will advance theory on how abrupt climate change propagates globally and provide a long-awaited climatic context for capstone events in Australia's natural history.

突然的变暖和变冷事件是地球最近气候周期的一个持续特征。令人惊讶的是，人们对这些事件如何影响澳大利亚的气候知之甚少。该项目将精确地重建这些事件期间澳大利亚南部的降雨和温度趋势。这些新的陆地和海洋数据将与模式模拟进行比较，以确定北半球突然的气候扰动到达我们地区的速度有多快，以及这种扰动发生的过程。研究结果将推进关于气候突变如何在全球范围内传播的理论，并为澳大利亚自然历史上的顶点事件提供人们期待已久的气候背景。
