CO2 record in the byrd ice core 50,000 - 5,000 years BP ...
The analysis of air in polar ice cores revealed 30% lower CO2 values during glacial periods than during interglacial periods. At present this is confirmed by results from six different ice cores, two from Greenland and four from Antarctica (1–5). In all cores the CO2 change coincides with the change...

The analysis of air in polar ice cores revealed 30% lower CO2 values during glacial periods than during interglacial periods. At present this is confirmed by results from six different ice cores, two from Greenland and four from Antarctica (1–5).
