27 (2): Ocean Circulation and Carbon Cycling
This issue of Past Global Changes Magazine highlights the paleoceanographic proxies and Earth system modeling studies used to reconstruct and understand changes in these processes over a range of climate states, from the Last Glacial Maximum 20,000 years ago to the warm climates of the early Cenozoic more than 55 million years ago, and the recent progress and ongoing challenges in reconstructing these changes, with an aim to inspire further research in these fields. It is a contribution to the PAGES OC3 working group.
