It took us 250 years to ramp up a (profitable) industry that ultimately boils down to turn turning craploads of alkane chains into water and craploads of carbon dioxide. Unless we find a process that does the opposite orders of magnitudes faster and at near zero cost, it'll take thousand of years to reverse the effects.
And I haven't begun yet on how we could possibly control such a system with 1) no measurable effect before decades 2) no idea if we fuck up something else with the side effects before centuries.
Frankly, we'd be better off learning to live with the effects.
