Past trends and future risk of climate extremes in southern Australia

长期干旱以及洪水和火灾风险的加剧给澳大利亚的社会和经济带来了重大挑战。这项建议旨在通过一套关于澳大利亚南部2000年来温度、降雨量/蒸发量和湿度的高质量记录，更好地解决十年极端气候事件的原因和风险。将开发新的地球化学分析并将其应用于湖泊沉积物的方法开发，这可能有助于气候、矿物和生物安全研究。有关气候变化背后机制的新知识预计将有助于基础研究，而面向未来的模型将使土地管理者和政策制定者能够更好地预测异常气候事件。

Prolonged droughts and periods of heightened flood and fire risk present a major challenge for Australia’s society and economy. This proposal aims to better resolve the causes and risks of decadal climate extremes through a suite of high quality records of temperature, rainfall/evaporation and humidity in southern Australia over 2000 years. Novel geochemical analyses will be developed and applied to lake sediments – method development which is likely to benefit climate, minerals and biosecurity research. New knowledge of mechanisms underlying climate variability is expected to benefit fundamental research, while future-facing models will allow land managers and policy makers to better anticipate extraordinary climate events.
