A long-term decline in atmospheric pCO2 over the Cenozoic, superimposed by higher frequency fluctuations, has been demonstrated by proxy reconstructions and provides fundamental feedbacks into the climate system and biogeochemical cycling. We welcome contributions advancing the current understanding of the causes, magnitude and timing of Cenozoic pCO2 variations, as well as research into global carbon cycle and biotic responses to these changes.
Proxy data and model submissions, including new pCO2 reconstructions, insights into proxy validation and research exploring links between the carbon cycle, productivity, adaptation and evolution on secular and orbital timescales are welcomed.
