The question is: Does the current
load of aerosols in the atmosphere already exceed that limit, in which case adding extra particles should not greatly affect cloud formation; or do they continue to be a limiting factor as pollution rises, so that added aerosols would continue to influence the clouds?

@lindaserena: The revised BC forcing estimate is merely based on a upward revision
of the BC
aerosol loading in the
atmosphere which seems to have been underestimated so far (higher than previously thought).
To elucidate human induced changes
of aerosol load and composition
in the
atmosphere, a coupled
aerosol and gas - phase chemistry transport model
of the troposphere and lower stratosphere has been used.
