Can turning carbon dioxide into stone slow down climate change?

I concluded Vox and PBS Terra examine planting trees to fight climate change by mentioning another carbon capture idea.
Planting trees serves as an example of "Nature knows best" for sequestering carbon, but this video shows it's not a good short-term solution. Another PBS Terra video shows one possible technique, but I'll save that for another video. Stay tuned.
Watch as PBS Terra asks Can Turning CO2 to Stone Help Save the Planet?

Can we turn atmospheric carbon dioxide into stone?
Spoiler Alert: carbon dioxide emissions are causing the planet to get warmer. But we may be able to use chemistry to solve this problem.

Out of Our Elements hosts Caitlin Saks and Arlo PĂ©rez Esquivel, joined by NOVA Producer Alex Clark, investigate how the planet naturally turns CO2 into stone over long periods of time, and how scientists and engineers are trying to speed up this process in hopes of capturing and storing atmospheric CO2.

They’re joined by Cornell University Environmental Engineer Greeshma Gadikota, who illustrates how you can test out a small-scale form of carbon sequestration in your own home, and Lamont Doherty Earth Observatory’s Angela Slagle, who explains which places on Earth and the kinds of oceanic rocks that could play a role in scaling up CO2-to-stone transformation.
The geologist in me approves of this "Nature knows best" method of capturing carbon dioxide and sequestering it. So does the Crazy Eddie in me.
