What is the cost of burning coal? On the April 22nd edition of Your Call, we’ll have a conversation with Richard Martin, author of Coal Wars: The Future of Energy and the Fate of the Planet. Coal has become a battleground in the fight against climate change. Martin traveled to Wyoming, West Virginia, and China to meet people on the front lines of the war on coal. He asks: Can we shut down Big Coal in time to save the planet – and ourselves? It’s Your Call with Rose Aguilar, and you.
