摘要/Abstract

摘要：

The reconstruction of air trapped in ice cores provides us the most di- rect information about atmospheric CH₄ variations in the past history.Ice core records from the “Three Poles (Antarctica, Greenland and Tibetan Plateau)” reveal the detailed fluctuations of atmospheric CH₄ concentration with time and are allowed to quantify the CH₄ differences among latitudes. These data are indispensably in the farther study of the relationship between greenhouse gases and climatic change,and of the past changes in terrestrial CH₄ emissions.Ice cores reconstruction indicates that atmospheric CH₄ concentration has increased quickly since industrialization,and the present day's level of atmospheric CH₄(1800 pp by) is unprecedented during the past Glacial-Interglacial climate cycles.
