An operators' manual helps keep your car or computer running at peak performance. Earth science can do the same for the planet. Join host Richard Alley – registered Republican, geologist, former oil company employee and expert on climate change and renewable energy — on a high-definition trip around the globe to learn the story of Earth's climate history and our relationship with fossil fuels. In Spain, Brazil, China and Texas, as well as at the U.S. Army's Fort Irwin and the U.S. Marine Corps' Camp Pendleton, a diverse cast of Earth "operators" are proving that when the Earth's bounty meets human ingenuity, there are many reasons to be optimistic about our energy future. As Alley says, if enough of us get involved, "we can avoid climate catastrophes, improve energy security, and make millions of good jobs."
