As global temperatures continue to rise, scientists are wondering if we need solutions beyond reducing emissions. Enter geoengineering. From sucking carbon straight out of the air to physically blocking out sunlight, the options may seem far-fetched. But as time runs out on conventional solutions to climate change, scientists are asking the hard questions: Can geoengineering really work? And, how much would it cost?

We answer all these questions and more during this episode of Lunch Hour Live as GBH Contributor Sue O’Connell chats with NOVA Producer, Caitlin Saks and CWCTP Filmmakers Ben Kalina and Jen Schneider to give you the behind-the-scenes scoop on the making of the film.
