Changes in oceanic uptake of carbon include changes in sea-surface temperatures (SST), ocean biogeochemistry, and ocean circulation.
Metric
Terrestrial carbon uptake does not increase under SAI relative to a no-SAI future.
Uncertainty
Low
Most research to date has found that oceanic carbon uptake will increase due to SAI, primarily from decreasing SST.
Decision relevance
Low
If SAI fails to increase ocean carbon sink compared it would not be ideal, but would not impact a decision to deploy.
