I do think material science break throughs for carbon capture is the most sensical way to solve this. But huge space projects or chalk dust airlifts are cool too.

We either need to to remove the carbon, affect the albedo of the earth, or deflect radiation coming to earth. Or all 3.
Deflecting radiation is a large engineering project. Maybe you should try to send a fleet of sun shields to the L1 Lagrange point. Or maybe you should try to pump large amounts of chalk dust into the atmosphere. I'm unsure what would be the better use of time. I've read that even just painting all the roads white buys us a few years.
Of all these possible solutions, the sun shield at the L1 Lagrange point might be necessary for humanity beyond just applications of global warming. It sounds big and ridiculous, but we really should consider it.
