There is such an equilibrium exchange of CO2 between atmosphere and the surface layer of the oceans, and there is the natural equilibrium that most of vegetation first grows and then decays and returns CO2 to the atmosphere.

For example, Dafflon et al. [2017] demonstrated in a polygonal tundra how soil electrical resistivity tomography and vegetation activity cameras can be merged with in situ measurements in a way to corroborate the role of active layer thickness and polygon geometry on spatial control on productivity, and demonstrate how changes in solute concentration and unfrozen water content in winter contributes to acceleration of permafrost thaw.

Surprisingly, researchers from the Universities of Exeter, Sussex, and Sheffield found that most of the methane that is released comes from decay of the new vegetation from the recently thawed top layers.

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.
