Fig. 5: Prediction of γCO2 under different scenarios.
From: A new indicator can assess absorption capacity for carbon dioxide and ocean acidification
Calculated using CMIP6 model temperature, salinity, pH, and pCO2. For details, please refer to the METHODS. a–d Global oceanic 2100 γCO2 at SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5, respectively. The ocean has largely lost its absorption capacity for CO2 in SSP5-8.5. e The latitudinal distribution of γCO2 in 2100 under different scenarios. f The latitudinal distribution of γCO2 in SSP5-8.5 under different years. g Future interannual variability of γCO2 for each scenario. h RF, γCO2, pH, and pCO2 in the Southern Ocean in 2100 at SSP5-8.5. In this condition, the limitation of the RF is apparent (In the Southern Ocean in 2100 at SSP5-8.5, Alk = 2203 μmol·kg−1, temperature = 2.0 °C, and salinity = 33.2). The RF increases and then decreases, as seen in the h-amplified plot, which is unsuitable for assessing the future seawater absorption capacity for CO2.
