doubling the concentration of atmospheric co2 from its pre-industrial level, in the absence of other forcings and feedbacks, would likely cause a warming of ~0.3°c to 1.1°c.

without feedbacks the radiative forcing of approximately 3.7 w/m2, due to doubling co 2 from the pre-industrial 280 ppm, would eventually result in roughly 1 °c global warming.
