Carbonate system sensitivities to various changes. a Salinity effect. b Temperature effect. c Pressure effect. d Biological effect. e Air–sea CO2 exchange effect. Calculations are based on GLODAP2 (n = 55,399; blue) and a LGM output from LOVECLIM58 (n = 71,768; gray). For ad, calculations assume no net air–sea CO2 change. Best fits of data are shown by red curves. See Methods for calculation details
