Air samples in an ice core from Site-J, Greenland, were analyzed to reconstruct the variations of the atmospheric CH_4 concentration in the northern hemisphere during the last 400 years. The results showed that the CH_4 concentrations were fairly constant during the first 200 years, the values being...
