These parameters are guesses, because there just isn't enough understanding of the complex and
chaotic climate system to parse out their different values, or to even be clear about cause and effect in certain processes (like cloud formation).
How and why would this planet's
chaotic climate system have such couplings.
Even our best climate scientists still have only a limited grasp of Earth's highly complex and
chaotic climate systems, and the many interrelated solar, cosmic, oceanic, atmospheric, terrestrial and other forces that control climate and weather.
