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."

in his first paper on the matter, he estimated that global temperature would rise by around 5 to 6 °c (9.0 to 10.8 °f) if the quantity of co 2 was doubled.
