# Nicolas Caillon Back to [[Topics/Climate Change Science and Policy Debate/Climate Change Science and Policy Debate|Climate Change Science and Policy Debate]] · [[Topics/Climate Change Science and Policy Debate/Research and Evidence|Research and Evidence]] **Role:** Ice-core geochemist (LSCE, France at the time); lead author of Caillon et al. 2003. - Lead author of **Caillon et al. 2003, "Timing of atmospheric CO₂ and Antarctic temperature changes across Termination III"**, *Science* 299:1728 ([doi](https://doi.org/10.1126/science.1078758)). - **Finding:** CO₂ lagged Antarctic temperature by **800 ± 200 years** at Termination III (~240 ka). The authors still described CO₂ as an amplifier of the orbitally initiated warming. - This is the one citation that does support Clack's "lag" wording, though not his conclusion.
