Integrated Global Estimation of Terrestrial Carbon Efflux

Carbon efflux (C_efflux) makes up 20% of total greenhouse gases emitted globally. Accurate global C_efflux is critical for projecting and responding to future global warming. However, current C_efflux estimates remain incomplete due to the omission of C_efflux released from the dissolution of inorganic carbon in calcareous soils (C_{efflux-calcareous}) and dissolution of lime in acidic soils (C_{efflux-acidic}). Here, we present a global te
