Projections of global climate change over the next century are so negative we must look to the Pliocene Epoch, more than 2.5 million years ago, for past analogues. Nonetheless, more recent episodes of rapid global warming during the late Pleistocene might approximate those expected for coming decades. This project will study past Australian regional temperature and rainfall responses to these events, on a high-resolution absolute timescale. The necessary analytical technologies are new, meaning a study of this scope could not previously be attempted, and they will be further developed under this project. Outputs will include spatial patterns and lead/lag relationships which can be used to supplement climate model predictions for Australia.

对下个世纪全球气候变化的预测是如此消极，我们必须向 250 万年前的上新世寻找过去的类似情况。尽管如此，最近更新世晚期全球快速变暖的情况可能与未来几十年的预期相似。该项目将在高分辨率的绝对时间尺度上研究过去澳大利亚区域温度和降雨对这些事件的响应。必要的分析技术是新的，这意味着以前无法尝试对这一范围进行研究，并且将在该项目下进一步开发这些技术。输出将包括空间模式和超前/滞后关系，可用于补充澳大利亚的气候模型预测。
