> It’s like saying your car’s gas gauge doesn’t tell you anything about how far you can drive, just how much gas you have in the tank. People have direct experience with the movement of their gas gauge and the distance they travel. They come to know directly that a certain point on the gauge represents a certain available distance to travel. They don't need to know anything about how the gas interacts with the air, and eventually ends up involved in a combustion reaction. There's no such direct experience with CO2 concentration in the atmosphere and heating. And atmospheric temperature is wildly variable on day to day time scales so it's impossible to make such a simple, direct, one to one association between them. You expect most people to have this particular grasp of high school level chemistry (and physics, I'd say), to the point where the interaction between CO2 and infrared radiation is accepted and internalized so well that one can directly jump from a graph of CO2 concentration to a conclusion about atmospheric heating. I'd say you're intentionally over simplifying. You have a conclusion you've come to, and you just expect others to accept it based on your point of view and your experience.
