Using the last glacial cycle to understand carbon-climate feedbacks

该项目旨在通过检查海洋对过去气候变化的反应，研究海洋的碳循环将如何对人为气候变化作出反应。该项目预计将在研究不足的南大洋印度部分产生灰尘反馈循环和微生物分解反馈循环的新记录。预期成果包括测试气候模型的新数据集，以及检测温度驱动的微生物分解变化的新方法。这应该会带来巨大的好处，包括更准确地估计人类可以安全排放多少碳，以及为澳大利亚是否应该采用海洋施肥作为应对气候变化的战略提供科学信息。

This project aims to investigate how the ocean’s carbon cycle will respond to anthropogenic climate change by examining its response to past climate variability. The project expects to generate new records of the dust feedback cycle and the microbial decomposition feedback cycle in the poorly studied Indian sector of the Southern Ocean. Expected outcomes include new datasets to test climate models, and a new method to detect temperature-driven changes in microbial decomposition. This should lead to significant benefits including more accurate estimates of how much carbon humanity can safely emit, and the science to inform whether Australia should adopt ocean fertilisation as a strategy to combat climate change.
