Description

Causes of deglacial atmospheric CO2 changes: A novel bottom-up approach. This project aims to resolve longstanding puzzles surrounding causes for past atmospheric CO2 variations through a novel bottom-up approach which constrains polar surface ocean conditions using deep-sea carbon cycle tracer reconstructions. Based on extensive new proxy data alongside models, our bottom-up approach will provide new insights into how the ocean operated to modulate atmospheric CO2 under diverse climate conditions during a critical but inadequately understood time interval known as the last deglaciation. This project is expected to markedly enhance mechanistic understanding of the global carbon cycle, with the benefit to improve our future climate predictability in face of rising atmospheric CO2..
