Ryan Green led a study investigating a the natural occurrence of geologic carbon release that is neutralized by alkalinity, so that it did not cause ocean acidification or atmospheric CO2 rise. The scale of the carbon pulse may have been twice the amount of all anthropogenic fossil fuel use combined. Studying this anomaly can give us clues about the effectiveness and environmental effects of purposeful Ocean Alkalinity Enhancement in an effort to neutralize anthropogenic CO2 and slow climate change.
