Michael, sketching the “social ecology” of possible future oceanic geoengineering technology would seem to some readers to veer into science fiction. And yet, there are good reasons why such a possibility should be researched as a potentially practical strategy, as you suggest. The physical ecology of our planet is bursting at the seams in terms of global warming, species extinction and habitat loss, resource security, human population, and potential for war and economic failure. Our global economy struggles with seven billion people now, let alone with the projected nine or ten billion population that could be alive later this century. What Holly Jean Buck has termed 'social ecology' is the determinant factor in sustaining physical ecology in the Anthropocene. To prevent conflict and collapse, we actually do need to develop transformative visionary ideas involving better use of the oceans. The oceans are the primary new frontier for the twenty first century, both in terms of how we can protect them and how they can be turned to productive sustainable use. Innovative pioneering technology, including ocean-focused geoengineering, is the best insurance to make global systems more robust against possible shocks and protect against the economic fragility that climate change will bring. The world ocean occupies 71% of our planet and contains well over a billion cubic kilometres of water, soaking up anthropogenic warming with consequences for climate change on land and at sea. My view, as flagged at the MIT CoLab Geoengineering competition, is that we should experiment with simple fabric technology to build floating platforms using bags of fresh water at sea. This concept could be scaled up profitably with potential applications for climate stabilisation and industrial production. Holly Jean Buck’s abstract cited below implies that geoengineering for profit is unethical. I prefer to view the profit motive as the best incentive for rapid expansion, innovation and results. The private sector is the driver of economic growth. A new “social ecology” focussed on applied oceanic technology can be regulated to achieve environmental goals within a capitalist market framework. The political economy of these debates is fascinating. Some environmentalists bring dubious assumptions to bear. I have argued that continued fossil fuel production can be compatible with climate stabilisation, but only if we store more carbon than we emit, and that this could be possible through large scale ocean based algae production. This geoengineering approach jars against the widespread view that emission reduction is the only path to climate stability. Holly Jean Buck implies that we should not try to keep existing systems functioning, and that a “critical reading” of geoengineering ideas sees capitalism as a central problem. I have read Buck’s article, and can forward it to anyone interested. Part of the “social ecology” of a future oceanic civilization could involve active technological management of carbon on a scale far larger than we have imagined to date. Seeing carbon as a valuable commodity provides the prospect of mining it from the atmosphere. Wave and tide power could make this geoengineering goal economic on large scale. The conversation about these topics should be opened up. Robert Tulip

Her statement of: "The logic that shapes the geoengineering research process could potentially influence social ecologies centuries from now." brings a spotlight to the issue of which type of projects should be given long term priority. SRM is important yet it is only a short term solution to a long term problem which has a multitude of attached issues. One avenue in which GE could be developed that would provide the broadest possible range of "social ecologies" for the long term, as well as climate warming mitigation, is found within the ocean based proposals. A well designed, organized and regulated large scale Ocean Afforestation/Mariculture project (combined with MCB) can provide for a wide range of humanitarian agendas such as food,fuel,fertilizer, jobs, room for climate refugees, ocean pH adjustment, SRM and direct air capture of CO2/CH4. All of these issues will eventually need to be addressed and provided for (for the foreseeable future). I believe Buck is correctly pointing out that GE can do far more than just address the first order technical issues of GW. If so, the only concept I'm aware of that can provide for that type of broad based vision is found within ocean based projects. The scale of a comprehensive ocean based project large enough to combat yearly emissions is hard for most people to conceive. The global surface area needed is continental in scale. Yet, our yearly population increase and the corresponding increase need for basic commodities can fill such a space within a few short years. The only long tern means to accommodate those needs, without transborder conflicts being a major limiting factor, seems to be expansion out into/onto the oceans. Our current 'social ecology' has little to do with the oceans beyond the endless (and damaging) harvest of the wild marine based biota, fuel and of course shipping is of major importance. Few realize that half of all wild caught fish are reduced to fish food! Clearly, the marine based oil and gas needs to be replaced with safer bio alternatives. And, if a major focus on ocean development is initiated, ocean transport would probably be revolutionized in short order (oceanic hyperloop?). However, the oceans can provide an even wider array of our basic needs and can provide them in a sound and sustainable way. The nutracline is the greatest store of nutrients on the planet and it is capped off by a highly active renewable energy environment. As we know, many groups and individuals are calling for a paradigm shift in thinking about our environment, resource management and "social ecology", as well as planetary cooperation at the environmental policy level. The $275B China is willing to spend over the next 5 years to clean up air pollution is a SMALL indication of the scale of the problem each nation faces on this meta issue. Marine based systems can pay for themselves over the long run, which is no small consideration. It may take over $8T just to compensate for our current level of environmental damage. For that cost, we deserve to see long term solutions at many different levels! We need a truly comprehensive meta plan which can address the first order environmental mitigation needs (GE) as well as the foundational matrix of issues which compel us to be so dysfunctional on the issues of food, fuel, fertilizer etc. Our species has few long term options which exclude the needed evolution of a large scale marine based meta system. I suspect that such an evolutionary step by our species (going back to the oceans) would eventually be recognizable as something of a oceanus hominis modification to the anthroprocene. Oceanic development could be a large game changer and may possibly provide for an ethical/sustainable social ecology so many desire. Any thoughts?
