While the urgent reduction of carbon dioxide (CO2) and other greenhouse gas emissions is needed as the primary activity to curb climate change, there is broad agreement for the need to remove CO2 already in the atmosphere. Given its outsized role in CO2 storage, the ocean can’t be ignored for its potential for marine carbon dioxide removal (mCDR) to help improve our stressed climate system.
