"You will have to forgive me when I cannot fathom how actively meddling with a complex system, which requires a substantial investment by our species in terms of scientists, research departments, universities, government offices - is going to result in a tightly controlled, well predicted result."

Any model of atmospheric carbon dioxide which is sufficiently accurate for generating public policy should suffice in predicting the results. After all, the model itself should not care what simulated means are being employed in increasing or reducing the amount of said compound, only its' effect at each concentration level.

there are multiple models modelling aspects of climate, many of which individually need super computer levels of horsepower. So separate models for ocean heating, or air currents etc.

all of which would have to re-work to account for the new entropy being added to the system, and its intended effects.

And this gets further complicated by different methods to change the environment.

Unless a climate scientist corrects me, its not as simple as just plugging in a x=x-c.

And that adds more complexity to the model too, not to mention the change in all the data - before G-eng, after G-eng.
