Atmospheric CO2 and Climate: Taylor Dome Ice Core, Antarctica

Abstract: Using new and existing ice core CO2 data from 65 - 30 ka BP a new chronology for Taylor Dome ice core CO2 is established and synchronized with Greenland ice core records to study how high latitude climate change and the carbon cycle were linked during the last glacial period. The new data and chronology should provide a better target for models attempting to explain CO2 variability and abrupt climate change.

摘要：本研究利用65~30 ka BP的新增与已有的冰芯二氧化碳数据，构建了泰勒穹顶（Taylor Dome）冰芯二氧化碳记录的全新年代序列，并将其与格陵兰冰芯记录进行同步，以探究末次冰期期间高纬度气候变化与碳循环之间的耦合关系。本研究获得的新数据与年代序列，可为旨在解释二氧化碳浓度波动与气候突变的模型提供更优的验证靶标。
