In my model, that is to say neglecting surprises but just considering the atmosphere / ocean / CaCO3 system, if we stopped releasing CO2 today and closed the terrestrial biosphere to either releases or uptake of carbon, just closed the system, CO2 would relax down to some value higher than today.

If the net feedbacks in the climate system are close to zero, then the warming from CO2 will be at or below the low - end projections of the IPCC.

I do not dispute the fact that elevated levels of CO2 should cause elevated temperature, in a closed system.

At a recent debate at Oxford University, organized by the OU Engineering Society, I gave the undergraduates an argument from process engineering (which you will find in outline in my Union College presentation, and in more detail in my Hartford College lecture) to the effect that the closed - loop temperature - feedback gain in the climate system (i.e., the product of the Planck parameter and the net sum of all unamplified feedbacks) can not much exceed 0.1, implying at most 1.3 K of warming per CO2 doubling, compared with the IPCC's central estimate of 3.3 K.

For instance, about half the total rise in atmospheric CO2 concentration has occurred in just the last 30 years — and of all the global life - support systems, the carbon cycle is closest to no - return.

It's only when deforestation and other land use changes made a net shift of carbon in the short term carbon cycle from plants back into the atmosphere, that humans began to make a net positive return of CO2 into the atmosphere (although deforestation is essentially reversible in principle), and it's very true to point out that industrial scale animal husbandry with its high cost in fossil - fuel - derived energy does mean that what might otherwise be a relatively closed system of cycling CO2 from the atmosphere through plants and then animals and back to the atmosphere, does become net positive with respect to CO2 emissions.

It is a closed circuit system, so the CO2 doesn't have to be replaced, and the batteries in the ring recharge themselves by capturing the energy of the spinning drum through induction.

Maybe, just maybe, CO2 reacts differently in an open and mixed system, at far, far, far lower concentrations than a closed, isolated, at far, far, far, far, far, far, higher concentration of CO2 system.
