  title = {Magnitude, Trends, and Variability of the Global Ocean Carbon Sink From 1985 to 2018},
  abstract = {This contribution to the RECCAP2 (REgional Carbon Cycle Assessment and Processes) assessment analyzes the processes that determine the global ocean carbon sink, and its trends and variability over the period 1985{\textendash}2018, using a combination of models and observation-based products. The mean sea-air CO2 flux from 1985 to 2018 is -1.6~{\textpm}~0.2~PgC~yr-1 based on an ensemble of reconstructions of the history of sea surface pCO2 (pCO2 products). Models indicate that the dominant component of this flux is the net oceanic uptake of anthropogenic CO2, which is estimated at -2.1~{\textpm}~0.3~PgC~yr-1 by an ensemble of ocean biogeochemical models, and -2.4~{\textpm}~0.1~PgC~yr-1 by two ocean circulation inverse models. The ocean also degasses about 0.65~{\textpm}~0.3~PgC~yr-1 of terrestrially derived CO2, but this process is not fully resolved by any of the models used here. From 2001 to 2018, the pCO2 products reconstruct a trend in the ocean carbon sink of -0.61~{\textpm}~0.12~PgC~yr-1~decade-1, while biogeochemical models and inverse models diagnose an anthropogenic CO2-driven trend of -0.34~{\textpm}~0.06 and -0.41~{\textpm}~0.03~PgC~yr-1~decade-1, respectively. This implies a climate-forced acceleration of the ocean carbon sink in recent decades, but there are still large uncertainties on the magnitude and cause of this trend. The interannual to decadal variability of the global carbon sink is mainly driven by climate variability, with the climate-driven variability exceeding the CO2-forced variability by 2{\textendash}3 times. These results suggest that anthropogenic CO2 dominates the ocean CO2 sink, while climate-driven variability is potentially large but highly uncertain and not consistently captured across different methods. {\textcopyright} 2023 The Authors.},
