    Ok, at least we are drilling down to your area of ignorance.

    Do you even know what the word "emissivity" means?You are claiming that somehow CO2 increase the amount of energy the earths surface absorbs from the sun.

    Yup that's exactly what I'm claiming. You need to educate yourself on blackbody radiation. You are still thinking in terms of conductive heat transfer.

    Energy can neither be created or destroyed. The earth has nowhere to conduct energy to, because it is sitting in the vacuum of space.
    Radiative heat transfer is the only thing left. You have to include the atmosphere as part of the earth when considering radiative heat transfer because we are all in the vacuum of space together.

    The amount of energy that can leave the earth is limited by the earth's emissivity. The atmosphere is a very big part of setting that emissivity, and CO2 is part of the atmosphere. The slower the energy leaves, the higher the surface temperature goes.

    I gave you an equation with average temperature, and you say that means I have a misconception, but you are incorrect there as well - the spot temperature at many places on the surface of globe at noon is colder than the earth's average temperature. Those places would be cooler at noon without the greenhouse effect. Think about it.

    I've given you the good stuff - the equation for radiative equilibrium including Boltzmann's constant, blackbody radiation, even the albedo of the earth.

    You've only responded with hand-waving.
