It seems to me there is much promise in influencing the natural carbon cycle in these kind of ways. Apparently natural processes release and absorb about 800 gigatons of CO2 annually against human emissions of 29 gigatons or so, so there seems a lot of scope to try to tip the natural balance a few percent. Especially if we go carbon neutral and are then looking to reabsorb a bit.

We don't see to be growing more trees anytime soon, and we aren't adding any new oceans either.

There's this kind of thing "Surge in plant growth explains slower CO2 rise over past decade" https://www.carbonbrief.org/surge-in-plant-growth-explains-s...

which has happened without really any planning. It's just that sort of stuff could be actively encouraged.
