The ocean covers about 70% of the Earth's surface and already buffers a large fraction of anthropogenic CO2 emissions (NRC, 2017); hence, much of the global capacity for natural carbon sequestration is in the ocean. Natural processes on land and ocean have removed roughly 55% of emitted CO2, but it may be possible to enhance both the uptake and longer-term sequestration potential of these processes. The National Academies will appoint an ad-hoc committee to explore ocean-based approaches to carbon dioxide removal (CDR) and sequestration and provides a path forward for research and development of promising CDR approaches.

As of 2021, atmospheric carbon dioxide levels have reached historically unprecedented levels, higher than at any time in the past 800,000 years. Worldwide efforts to reduce emissions by creating a more efficient, carbon-free energy system may not be enough to stabilize the climate and avoid the wor...
