ABSTRACT:  In order to evaluate ocean fertilization in the larger context of other proposed strategies for reducing the threat of the global warming, a wide range of different climate change mitigation approaches are compared in terms of their long-term potential, stage of development, relative costs and potential risks, as well as public acceptance. This broad comparative analysis is carried out for the following climate change mitigation strategies: supply-side and end-use efficiency improvements, terrestrial and geological carbon sequestration, CO2 ocean disposal and iron fertilization, nuclear power, and renewable energy generation from biomass, passive solar, solar thermal, photovoltaics, hydroelectric and wind. In addition, because of the inherent problems of conducting an objective comparative cost–benefit analysis, 2 non-technological solutions to global warming are also discussed: curbing population growth and transitioning to a steady-state economy.

KEY WORDS: Ocean fertilization · Climate change mitigation technologies · Efficiency · Carbon sequestration · Renewable energy · Cost–benefit analysis · Population growth · Economic growth
