Testing the mechanisms and effects of abrupt and extreme climate change

该项目旨在解决过去突然和极端的全球气候变化的时间、变化速度、机制和影响。对于最近的地质记录中的突然和极端变暖事件，这些都是不确定的，因为很难将过去50,000年来放射性碳时间尺度上的陆地和海洋古气候和动物记录与独立测年的冰芯进行比较。通过使用每年解析的年轮记录，该项目将发现突然和极端的变化何时、如何以及对全球气候和物种/生态系统产生了什么影响。

This project aims to resolve the timing, rate of change, mechanisms and effects of past abrupt and extreme global climate change. These are uncertain for abrupt and extreme warming events in the recent geological record, due to difficulties comparing terrestrial and marine palaeoclimate and faunal records on radiocarbon timescales with independently dated ice cores over the last 50,000 years. By using yearly-resolved tree ring records, the project will discover when, how and what effect abrupt and extreme change had on global climate and species/ecosystems.
