Emissions (GtC/yr)

Carbon moves between four great reservoirs — atmosphere, surface ocean, deep ocean, and biosphere — through exchange fluxes. Add fossil emissions to the atmosphere box and watch how slowly the oceans and land can draw it back down. The deep ocean is huge but exchanges slowly.

Governing equation

\frac{d C _{a t m}}{d t} = E - F_{a s} - F_{ab} = 10.0 - 6.8 - - 3.6 GtC/yr

Reading this result: At 10 GtC/yr the surface ocean and biosphere buffer part of the input, but they saturate, so atmospheric CO₂ keeps drifting upward rather than settling.
