... LEGAL AND ETHICAL ISSUES Ocean iron fertilization directly manipulates the base of the ocean food web in order to stimulate the growth of phytoplankton to enhance carbon uptake and, as such, is of concern from both legal and ethical perspectives. The implications for the health of the marine ecosystem are not well known and could potentially be substantial on regional scales, both ecologically and economically.

... There have already been examples of an iron fertilization experiment that has been temporarily blocked by nongovermental organizations to prevent "dumping" of iron in the Southern Ocean (Schiermeier, 2009a,b) , as well as controversy surrounding the actions of a unilateral and uncoordinated activity that involved experimenting with ocean fertilization in the Northern Pacific (see Box 2.1)

... will require adoption of CDR techniques on the international scale. The social context is less about understanding how one set of actions affects the global climate or large numbers of people in the short term and more about how to mobilize multiple nations to engage in a coordinated effort.

... Integrated assessment models (IAMs) are common tools for -- among other things -- evaluating the potential role of CDR techniques in the various climate change mitigation scenarios, as they include many of the interconnected complexities such as climate and atmospheric modeling, agriculture and land use, and various technologies to be implemented with their related economics (Kriegler et al., 2013)

... Overall, the inclusion of BECCS into integrated assessment models allows for significantly lower targets to become possible at reduced costs. It is important to emphasize that both BECCS and DACS, which are the CDR approaches that appear to have the greatest potential for carbon dioxide reduction given the current state of knowledge, depend on the availability of geologic reservoirs capable of accepting and reliably storing massive amounts of CO2 (discussed in more detail in Chapter 3)
