New strategy to prevent global warming: just freeze all of the CO2 out of the air!

That’s one of the ways proposed for terraforming Venus. Put in a sun shield to freeze the planet, let the CO2 snow down, then process the CO2 into something that can sequester it away so it doesn’t just go back into the atmosphere after removing the sun shield.
Of course none of that is technically possible right now, but it’s a lot easier on a planet that has no (known) life to destroy while working through the process.
