his best estimate is that the  warming in response to a doubling of co2 concentration, which may happen  this century unless the usual suspects get away with shutting down the  economies of the west, will be a harmless 1 fahrenheit degree, not the 6  f predicted by the ipcc."

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.
