Ocean Fertilization: Science, Policy, and Commerce

Is ocean fertilization credible and creditable?

It is possible that the increase in atmospheric carbon dioxide, which drives global warming, could be partially mitigated by adding iron to ocean waters. In their Policy Forum "Dis-crediting ocean fertilization" (12 Oct., p. 309), S. W. Chisholm et al. argue that "the known consequences and uncertainties of ocean fertilization already far outweigh hypothetical benefits." We believe that they ha...

Ocean fertilization: a potential means of geoengineering?

The oceans sequester carbon from the atmosphere partly as a result of biological productivity. Over much of the ocean surface, this productivity is limited by essential nutrients and we discuss whether it is likely that sequestration can be enhanced by supplying limiting nutrients. Various methods of supply have been suggested and we discuss the efficacy of each and the potential side effects t...

Historians of science have participated actively in debates over American science policy in the post-World War II period in a variety of ways, but their impact has been more to elucidate general concepts than to effect specific policy changes. Personal experiences, in the case of the debate over global warming, have demonstrated both the value and the limits of such involvement for the making o...
