Our guest today is David Wallace Wells, a deputy editor at New York Magazine, and author of a vividly distressing new book about the all-encompassing perils of climate change, called The Uninhabitable Earth. With every full-throated warning, on page after page, Wallace Wells fully embraces the notion that eloquently targeted fear can shake the public into action. He also presents a gripping argument that scientists, and others charged with sounding the alarm, have historically been far too timid, for fear of being branded "alarmist" or dismissed as leftist. Now is the time to panic, Wallace Wells argues. In fact, that moment passed long ago. So now what? Host Jamilah King helps listeners locate some moments of hope and optimism amid the fear.
