> There are an infinite number of inputs and outputs. No, there are a finite number of particles in a finite space making up the Earth's climate. > The climate isn't that simple. It's unfathomably complex. Nothing is simple unless you simplify it. A baseball is an unfathomably complex collection of billions of billions of particles interacting with the entire universe until you abstract it to a simple Newtonian point mass, but you'll still make all the relevant predictions to >99% accuracy. Global warming can be accurately modeled by a very simple system: There is the atmosphere, the ocean, the Earth itself, and the rest of the universe. Over any finite time period there is a simple real number change in the temperature of these 4 subsystems modeled by thermodynamics, and there can be no net change in temperature due to conservation laws. Can we predict these changes as accurately as we can predict simple Newtonian systems? No. But we can still predict them to a good degree of accuracy in the short term.
