The ocean has absorbed over 90% of the heat from recent anthropogenic greenhouse warming. This chapter reviews a variety of ocean-related methods for slowing down and eventually halting this warming. “Blue carbon” reservoirs store more carbon than terrestrial equivalents, although are still limited compared with global negative emissions needs. Oceanic carbon uptake could be augmented via iron fertilization, although this method presents challenges. Algal-based biomass energy with carbon capture and storage (ABECCS) offers opportunities for carbon-neutral fuel alternatives as well as for negative emissions. Total carbon dioxide removal potential is estimated at 15–33 Pg CO2/year by mid-century and 33–95 Pg CO2/year by the end of the century, which could offset current and projected CO2 emissions. ABECCS can also coproduce high-protein feed for aquaculture and reduce demand for agricultural land. Furthermore, combined with effective ocean blue carbon management and terrestrial methods, ocean-based carbon removal can play a critical role in climate stabilization.
