从南极洲康科迪亚冰丘获得的末次盛冰期到全新世过渡期间大气二氧化碳（CO2）浓度的记录显示，在6000年的时间内，在四个明显可区分的间隔中，体积增加了百万分之76。CO2浓度与南极温度的密切相关表明，南大洋在导致CO2浓度升高中起着重要作用。然而，CO2浓度变化与大气甲烷浓度变化的相似性表明，作为甲烷主要来源的热带和北方半球的过程也对大气CO2浓度产生了重要影响。
A record of atmospheric carbon dioxide (CO2) concentration during the transition from the Last Glacial Maximum to the Holocene, obtained from the Dome Concordia, Antarctica, ice care, reveals that an increase of 76 parts per million by volume occurred over a period of 6000 years in four clearly distinguishable intervals. The close correlation between CO2 concentration and Antarctic temperature indicates that the Southern Ocean played an important role in causing the CO2 increase. However, the similarity of changes in CO2 concentration and variations of atmospheric methane concentration suggests that processes in the tropics and in the Northern Hemisphere, where the main sources for methane are Located, also had substantial effects on atmospheric CO2 concentrations.
