If so, I think we want to include tightly coupled chemical and biological processes, in that case — for example, the chemical fate of atmospheric methane over time, the effects of increasing atmospheric CO2 on oceanic acid - base chemistry, and the response of the biological components of the carbon cycle to increased temperatures and a changing hydrologic cycle.

So how can we tell what effect CO2 is having on temperatures, and if the increase in atmospheric CO2 is really making the planet warmer?
Unless more CO2 from human sources could increase total atmospheric density it could not have a significant effect on global tropospheric temperature.

We do not need models to anticipate that significant rises in atmospheric CO2 concentrations harbor the potential to raise temperatures significantly (Fourier, 1824, Arrhenius, 1896), nor that the warming will cause more water to evaporate (confirmed by satellite data), nor that the additional water will further warm the climate, nor that this effect will be partially offset by latent heat release in the troposphere (the «lapse - rate feedback»), nor that greenhouse gas increases will warm the troposphere but cool the stratosphere, while increases in solar intensity will warm both — one can go on and on

In fact, recent research shows that changes in atmospheric CO2 levels have no significant effect on global temperatures.
By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.
The big debate about CO2's effect on global surface - level air temperatures is what will happen when atmospheric CO2 doubles in concentration from pre-industrial times, i.e., increases from 0.026 % (280 ppm) of the atmosphere to 0.056 % (560 ppm).
