Recapturing atmospheric CO2 means working to transform from a high-entropy state to a lower-entropy state. That's not going to happen for free. So you need to have: 1) A fast efficient carbon-capture mechanism. 2) A way to generate lots and lots of power that doesn't itself produce CO2. You're not describing a "single scientific advance" as much as you're describing dozens or hundreds of major feats of engineering. I'm not saying it couldn't happen, but I would not bet the planet on it.
