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°).

taking planetary heat uptake rate as the rate of ocean heat uptake estimated by the ipcc ar4 as 0.2 w/m2, yields a value for s of 2.1 °c (3.8 °f).
