Ocean-based carbon dioxide removal approaches
Human emissions of carbon dioxide (CO2) and other greenhouse gases drive ongoing climate change and limiting the extent of further global warming is a key element of the Paris Climate Agreement. Climate stabilization efforts will require net zero human CO2 emissions by roughly mid-century, and many climate scenarios require substantial levels of deliberate CO2 removal from the atmosphere to meet these goals. At present, the natural processes in the ocean act as a major sink for anthropogenic CO2, and various biological and industrial technologies have been proposed for enhancing ocean CO2 removal.
