摘要：

The reconstruction of air trapped in ice cores provides us the most di-rect information about atmospheric CHvariations in the past history.Ice corerecords from the“Three Poles（Antarctica,Greenland and Tibetan Plateau）”re-veal the detailed fluctuations of atmospheric CHconcentration with time and areallowed to quantify the CHdifferences among latitudes.These data are indis-pensably in the farther study of the relationship between greenhouse gases andclimatic change,and of the past changes in terrestrial CHemissions.Ice coresreconstruction indicates that atmospheric CHconcentration has increased quicklysince industrialization,and the present day’s level of atmospheric CH（1800 pp-by）is unprecedented during the past Glacial-Interglacial climate cycles.
