CLIMATE CHANGE:
Enhanced: Ups and Downs of CO2 Uptake

Paul Quay [HN14]

Thanks to international efforts, CO2 concentrations in the atmosphere are monitored at ~100 sites worldwide. By comparison, very few decade-long ocean CO2 records exist, and consequently very little is known about the variability of CO2 concentrations in the surface ocean. In his Perspective, Quay highlights the report of Gruber, Bates, and Keeling, who present an 18-year record of surface-ocean CO2 concentrations near Bermuda. The study provides much-needed observational data for testing models, but more such records are needed to predict how much anthropogenic CO2 will be taken up by the ocean.
