    Temperature rise with infinite greenhouse effect

    How fast would the atmosphere heat up if every erg of energy incident on it stayed and went into heating? A degree an hour, perhaps?

    Lessee. Assuming a spherical cow:

    Heat capacity of air (Cp) = 1000 J/K.kg
    Mass of atmosphere (M) = 5.15e18 kg
    Solar "constant" (sc) = 1360 J/s.m^2
    Radius of Earth (R) = 6370000 m

    (pi x R^2 x sc)/(Cp x M) = 3.4e-5 K/s = 0.1 K/hr

    So my WAG was just an order of magnitude off your BOTE estimate. Not too bad.
