KEYNOTE PERSPECTIVE. Status of the atmospheric CO2 reconstruction from ice cores analyses

This note presents the development of the studies on past atmospheric CO2 variation based on ice-core analyses. Its aim is also to give the main references of these studies from the time of the discovery of the glacial-interglacial CO2 change in 1980 to the time of the Vth International CO2 Conference of Cairns in 1997.
