There are a lot of hypothetical deliberations on where this «missing» CO2 is going: into increased terrestrial plant photosynthesis or soil absorption, dissolved into the ocean, where it is buffered chemically or converted by photosynthesis from phytoplankton, entering the food chain and possibly getting converted to carbonates that eventually end up on the ocean floor, into limestone through weathering or dissipated into space, etc..
