No problem can be solved from the same level of consciousness that created it. - Albert Einstein
Is reforestation not simply the best way to do this?
In a very limited fashion it is. You can plant a forest and that amount of CO2 is what it’ll be able to pick up. Trees will die, rot, emit their CO2 back into the air while new trees pick it up again. The system would reach a maximum equilibrium quickly and the relative amount of CO2 picked up isn’t that high.
Most CO2 is actually processed by algae anyway
Then cut the tree and trow it in a cave or something.
That method would work better with algae or seaweed farming. Ultimately, it is solar energy capture, which requires a large area. We are already short of arable land to work with. A lot of the ocean surface is effectively a life desert. Using it for large scale carbon capture and storage would work quite well.
If we stop emitting greenhouse gases nothing will get better, it will just stop getting worse. We also have to remove all the GHG that we put into the atmosphere.
“Stop getting worse” is a pretty major improvement. And yes, trees work as carbon sequestration.
Most (all?) CCS is not grabbing random carbon from the atmosphere. It’s pulling it out of smokestacks so you can keep burning fuel while claiming it’s green. It is not net negative even if working as intended.
