This project intends to generate a near-continuous annual temperature reconstruction for the past 10 000 years using low-elevation Huon pine from south-western Tasmania. The unprecedented length and temporal resolution of the reconstruction would offer new insights into temperature variability at decadal, centennial, and millennial time scales and establish a unique record describing the nature, timing, and intensity of abrupt temperature changes associated with known events in the palaeoclimate record. The detailed understanding of historical temperature variability and past abrupt climate change provided by the tree-ring record would provide a historical context for recent and future climate variability.

该项目旨在利用来自塔斯马尼亚西南部的低海拔休恩松进行过去一万年近乎连续的年度温度重建，其前所未有的长度和时间分辨率将为十年间、百年间的温度变化提供新的见解。和千年时间尺度，并建立一个独特的记录，描述与古气候记录中已知事件相关的温度突变的性质、时间和强度。对历史温度变化和过去气候突变的详细了解。树木年轮记录将为近期和未来的气候提供历史变化背景。
