Atmospheric CO2 response to AMOC changes under high and low obliquity

Meltwater experiments are performed with the Earth system model of intermediate complexity LOVECLIM (Goosse et al., 2010) under 49ka and 12 ka boundary conditions with their appropriate obliquity values as well as with low obliquity (22.1 deg). The impact on atmospheric CO2 and the oceanic and terrestrial carbon cycle is assessed to understand the impact of obliquity on the carbon cycle. Details on the scientific context and experimental design are in Legrain E., Capron E., Menviel, L. et al., "Centennial-scale variations in the carbon cycle enhanced by high obliquity", 2024.
