The reduced DMS emissions induce a significant positive radiative forcing of which 83 % (0.4 W / m2) can, in the model, be attributed to the impact of ocean acidification alone.
More relevantly though man is increasing CO2 at a rate unprecedented in earth's history — as far as we know and CO2 has significant impact on radiative transfer in the atmosphere and pH in the surface ocean.
Twohy et al. (1989) concluded from measurements off the coast of California and from simple radiative calculations that the observed levels of soot would not lead to a significant impact on the cloud albedo.

There are no studies yet to confirm unambiguously that the GCM estimates of the radiative impact associated with the second indirect effect can be interpreted in the strict sense of a radiative forcing (see Sections 6.1 and 6.8.2.2), and very few observations exist as yet to support the existence of a significant effect.
