Is The CO2 Effect Too Weak To Explain Warming?

   That's [1]what this guy, Nasif Nahle Sabag, is arguing:

     For example, the real radiative equilibrium temperature of Earth is
     300.15 K (27 °C), and we want to know the anomaly caused by carbon
     dioxide, which concentration in the atmosphere was 381 ppmv. If the
     standard concentration of CO2 in the atmosphere is 280 ppmv
     (another subjective number because the real one was fixed by
     scientific associations and boards, and its value is 350 ppmv), the
     anomaly in the temperature of the lower troposphere (the layer of
     air just above the ground and in contact with the surface with not
     more than one meter thick) caused by CO2 (Partial Pressure from 381
     ppmv [CcdL] = 0.00034 atm-m) under a total atmospheric pressure of
     1 atm is:
     [Equations at link]
     Thus, the anomaly of the lower troposphere temperature caused by
     the increase of CO2, on June 15, 2007 at 18:05 hrs. (UT) was 0.02
     K, which is equal to 0.02 °C.

   Seems to hang together fairly well. Anyone care to try to shoot holes
   in this?
   Sabag appears to believe increases in solar radiation are more likely
   to be responsible,[2] and argues that case in this thread, citing data
   that do appear to show solar irradiance has been rising both in the
   past 400 years and the past 50, though (as pointed out in the thread)
   the correlation to temperature is lagging (ironically, [3]lagging
   correlation is of course the same argument warming skeptics have made
   against the long-term CO2/temperature correlations), and he gives some
   interesting formulas for surface warming based on irradiation.
   We should be skeptical, but in both directions: with the recent
   revelations that James Hansen is not only receiving six-figure
   payments from Soros but [4]actually once worked to bolster claims the
   same problem (air pollution from fossil fuels) would bring about a
   "catastrophic" Ice Age, the whole climate change industry starts to
   look like a bit like a cause in search of a convenient crisis.
