30°C is 303 Kelvin. Half of that is 151 Kelvin, which translates into a fairly mild -122°C!

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

Dry snow doesn't sound like too bad of a proposition on its own.

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.

That sounds great. I bet it would be even easier to do on earth. If anyone gave a shit.

the sequestering step is actually kinda easy, it's the sun shield that's the hard part
