The «old» and «new» CO2 in an air parcel is at the same temperature.
A warm parcel of air will radiate more than a colder parcel, even at the same 390 ppm of CO2 in the air due to the population of the different rotational and vibrational energy states of the GHGs from collisions with other atmospheric molecules in the LTE limit.
The parcel of air changes its own temperature and pressure at the same rate as the temperature and pressure of the surroundings changes.
«Take two identical volumes (parcels) of air, taken from somewhere at a midlevel in the troposphere, with each parcel containing an identical number of gas molecules and the same amount of heat energy to start.
The constant speed moving parcel of the ideal gas is the same solution as still air for hydrostatic equilibrium.
As it rises the parcel of air loses energy and expands until the temperature is the same as the surrounding air.
The expansion laterally increases pressure laterally but pressure from above stays the same because even if the atmosphere were to expand there would be the same number of molecules above the air parcel.
Once it expands it pushes against the adjoining parcels so pressure increases in the horizontal plane but pressure in the vertical plane remains the same so the expanded and lighter air parcel moves in the direction of least resistance which is upward.
Again, pressure in the vertical plane stays the same so the contracted and heavier air parcel moves in the direction of least resistance which is downward.
Since liquid water weighs the same as the water vapor it condensed from, there is no change in the weight of the column of atmosphere above our parcel of air, whence the pressure remains unchanged, although the parcel may change (very slowly) in volume.
Given two almost identical parcels of air at the same temperature and pressure, the one with more water vapor will be less dense.
