The one burning question I have about CO2 is this: how is it possible for the Keeling curve to keep on rising for eighteen years in a row if there was no parallel warming this was supposed to create? None of the highly technical analyses in this paper are nothing but side issues compared to this conundrum.
The rate of change of CO2 has been fairly constant for the time that temps have been fairly constant and there is a marked similarity in the deviations in both over that period.

This is variation around constant rate of change very close to 2ppm/year.
Previously, the rate of change of CO2 was increasing in a similar way to the increase in global mean SST. Now SST is paused the dCO2 is paused.
The world has been warming for about 300 years and the deep oceans will not have reached pCO2 equilibrium with the atmosphere since 1998. As the warmth penetrates and diffusion mixes surface water with deeper water, the massive reserve in the ocean will continue outgassing.
Your burning question arrises from an unstated and unwarrented assumption that SST ( sea surface temperature ) will fully account for any temperature related change in CO2. It is an indication and closely matches short term change with primarily reflects shallow changes, but the ocean is not one uniform reservoir.
