Acceleration of the Last Glacial Termination Due to Climate-Carbon Cycle Feedbacks

该项目旨在通过气候系统对千年时间尺度上大气pCO 2变化的响应、全球碳循环对气候变化的响应以及耦合的气候-碳系统对轨道变化的敏感性，促进对冰川-间冰期变化的理解。 研究海冰、大气水汽与陆地和海洋碳循环之间的耦合作用，以确定冰期的终止。重点将是21-10 ka BP期间使用低分辨率的全球大气-海洋-海冰-植被-海洋碳模型（LOVECLIM）。 将进行几次涵盖该时间段的瞬态模拟。 对研究生的支持是这个项目的主要内容。

This rescoped project aims to contribute to understanding of glacial-interglacial variations via the response of the climate system to atmospheric pCO2 variations on millennial time scales, the response of the global carbon cycle to climate change, and the sensitivity of the coupled climate-carbon system to orbital variations. The coupling between sea ice, atmospheric water vapor and the carbon cycles over land and in ocean will be studied for the termination of glacial epochs. Focus will be on the period 21-10 ka BP using a low-resolution global atmosphere-ocean-sea ice-vegetation-marine carbon model (LOVECLIM). Several transient simulations covering this time period will be conducted. Support for a graduate student is the main element of this project.
