Marine-based management of atmospheric carbon dioxide and ocean acidification
Session ID#: 80136
Session Description:
Ocean biology, chemistry and physics play a central role in naturally controlling oceanic/atmospheric CO2 levels. To avoid major global climate impacts and ocean acidification, reducing CO2 emissions is no longer sufficient; CO2 removal from the ocean/atmosphere system is now also required. This session will explore ways of restoring, enhancing, and augmenting naturally-occurring marine processes for regulating oceanic and atmospheric CO2 and ocean acidity levels. Specific examples include, but are not limited to: Blue Carbon, macrophyte introduction, aquaculture, permaculture, nutrient enrichment, marine BECCS, enhanced weathering, alkalinity addition, enhanced upwelling/downwelling, and chemical or physical seawater CO2 stripping, conducted at local to global scales. In addition to technical aspects, presentations on the economic, regulatory, policy, geopolitical, governance, legal and ethical implications of the preceding are also invited.
