CO2 measurements from polar ice cores: more data from different sites
Air in the bubbles of polar ice has in principal the same composition as the atmospheric air at the time of ice formation. Based on this relationship, an increase in atmospheric CO2 since the beginning of industrialisation has been documented (Neftel et al. 1985, Pearman et al. 1986) in Antarctic ic...
