Can Turning CO2 to Stone Help Save the Planet?

Caitlin Saks and Arlo Pérez Esquivel, joined by Alex Clark, investigate how the planet naturally turns CO2 into stone, and how scientists are trying to speed up this process. Cornell University Environmental Engineer Greeshma Gadikota illustrates how you can test out carbon sequestration at home. Lamont Doherty Earth Observatory’s Angela Slagle explores scaling up CO₂-to-stone transformation.
