elementary radiative-transfer calculations demonstrate that a natural surface global brightening amounting to ~1.9 wm–2 over the 18-year period of study would be expected – using the ipcc’s own methodology – to have caused a transient warming of 1 k (1.8 f°).

the global temperature increase since the beginning of the industrial period (taken as 1750) is about 0.8 °c (1.4 °f), and the radiative forcing due to co 2 and other long-lived greenhouse gases – mainly methane, nitrous oxide, and chlorofluorocarbons – emitted since that time is about 2.6 w/m2.
