Bill McKibben has spent four decades warning us about climate change. Much of what he predicted has come true. And yet, his new book Here Comes the Sun is more hopeful than you might expect. That’s because, for the first time, we have a genuine alternative: Solar and wind energy are now the cheapest, fastest-growing sources of power on Earth. The revolution has already begun. This week, Sean is joined by McKibben to talk about the peril and promise of this moment. They explore how close we are to catastrophe, why each fraction of a degree of warming matters, and how the fossil fuel industry is fighting a desperate last stand. They also discuss the politics of energy in the age of Trump, why Texas and Utah may hold surprising lessons, and how cheap, abundant power could transform not just the climate fight but democracy itself.
