But we may be able to use chemistry to solve this problem. Out of Our Elements hosts Caitlin Saks and Arlo Pérez 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. -- You can seek out our hosts here: :: Caitlin Saks :: Twitter:   / caitlin_saks   :: Arlo Pérez Esquivel :: Instagram:   / perezarlo   :: Alex Clark :: Instagram:   / alexclarkdotcom   Twitter:   / alexclarkdotcom   -- Produced and Hosted by: Caitlin Saks and Arlo Pérez Esquivel With Alex Clark Associate Producer: Angelica Coleman Associate Researcher: Christina Monnen Science Advisor: Matthew Eddy Animation: Edgeworx Studios Executive Producers: Julia Cort and Chris Schmidt Executives in Charge for PBS: Adam Dylewski, Jess Kasza Assistant Director of Programming for PBS: Niki Walker Digital Editor: Hanna Ali Senior Digital Editor: Sukee Bennett Rights Manager: Hannah Gotwals Business Manager: Elisabeth Frele Digital Managing Producer: Kristine Allington Coordinating Producer: Elizabeth Benjes Director of Public Relations: Jennifer Welsh Legal and Business Affairs: Susan Rosen and Eric Brass Archival: Channer/Wikimedia/CC BY-SA 3.0 iStock Mitch Butler Richard Pyle/Lava Video Productions Storyblocks Unit TV and Film Music: APM Special Thanks: Ben Kalina Jen Schneider Frauke Levin Rob Tinworth Funding for NOVA provided by the David H.
