For that, it's assumed that the CO2 would be added very rapidly and nothing else would have time to adjust
except the radiative heat flux, which reacts always immediately.
(hint: because vacuum insulates perfectly for everything
except radiative heat loss)
Not exact matches
(Within a typical atmosphere, as on Earth,
heat transport by conduction and molecular mass diffusion are relatively insignificant for bulk transport (there is some role in smaller - scale processes involving particles in the air),
except when the net
radiative flux and convective flux are very very small (not a condition generally found on Earth).
Radiative heat transfer is meaningless over large distances
except in a vacuum which our atmosphere is not.
There is no
radiative effect or
radiative transfer of
heat across an opaque material like the air (figure 6 - A
except in the window where 20 W / m ² go un-intercepted from surface to cosmos).
