    I am trying to explain the procedure by which a doubling of CO2 is calculated. So far I have:

    A doubling of CO2 is calculated by first running the model with CO2 fixed at pre-industrial levels (280 ppm) then it is run again with CO2 levels fixed at double this value (560 ppm). Ssummarised as the calculated diffference in GMST between the two runs.

    What is the model?
    Also what physical feedback processes affect the value?

    When i think about how doubling of CO2 is: CO2 x 2 = C2O4

    Well, there are different angles to consider. There is no absolute result in a system with as many variables as the earth has, if that is your attempt.

    The infared window and Beer-Lambert law both come into play. As the IR window gets smaller, the feedback increased. As the gas level increases, the value of the heat retention also increases.
