Short summary

Atmospheric CO₂ is key for climate change. CO₂ is lower during the oldest warm period of the last million years, the interglacials, than during the most recent ones (since 430 000 years ago). This difference has not been explained yet, but could be due to changes of ocean circulation. We test this hypothesis and the role of vegetation and ice sheets using an intermediate complexity model. We show that only small changes of CO₂ can be obtained, underlying missing feedbacks or mechanisms.
