Ocean carbon uptake is the elephant in the room for any plan to remove carbon from the atmosphere. If our plan is to remove carbon from the atmosphere the oceans will begin releasing carbon to mitigate the effectiveness. This seems like a better plan.
To help scale this CO2 problem, the larger test unit being deployed next year will remove 10 metric tons per day. Worldwide we add 1,000,000 metric tons of C02 every 15 minutes. The scale of the problem is one reason I'm skeptical that we'll actually accomplish a solution that matters while we continue to use fossil fuels.
