given that a doubling of carbon dioxide would change the surface heat flux by only two watts per square meter, it is evident that a small change in cloud cover can strongly affect the response to carbon dioxide."

radiative forcing:20
a typical value of λ, 0.8 k/(w/m2), gives an increase in global temperature of about 1.6 k above the 1750 reference temperature due to the increase in co 2 over that time (278 to 405 ppm, for a forcing of 2.0 w/m2), and predicts a further warming of 1.4 k above present temperatures if the co 2 mixing ratio in the atmosphere were to become double its pre-industrial value; both of these calculations assume no other forcings.
