It's just not going to happen.
We've been dumping CO2 into the atmosphere for a long time. We'd have to equal that removal to take hundreds of years to get rid of it. Not going to happen. Harvest it for graphene? Sure, Why not? But advertising it as a way of stopping the warming is a sales pitch for investors.
And that includes trying to sequester it and pump it underground. The scale is impossible. Carbon credits? Another money grab. Forget it. We terraformed this planet and now we have to live with it.
Glad I'm old and cynical.
