Season 47 Episode 15 - Can We Cool the Planet?
7.0 ?
1974
Documentary
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? How much would it cost? And what are the risks of engineering Earth's climate? (Premiering October 28 at 9 pm on PBS)
