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.

该项目旨在使用塔斯马尼亚西南部低海拔的Huon松来重建过去10 000年的近连续年温度。前所未有的重建长度和时间分辨率将提供新的见解温度变化在十年，百年和千年的时间尺度，并建立一个独特的记录描述的性质，时间和强度的突然温度变化与已知的事件在古气候记录。树木年轮记录提供了对历史温度变化和过去气候突变的详细了解，这将为最近和未来的气候变化提供一个历史背景。
