Threshold is a Peabody Award-winning podcast about people and the planet. Each season, we do a deep dive into one pressing environmental story, exploring it through the intersections of science, politics, culture, and environmental justice. We aim to make space for thoughtful, honest, and intersectional conversations about human relationships with the natural world. Season 4: "Time to 1.5" documents this profound moment in human history, when the window for keeping global heating to 1.5ºC is still open—just barely. Season 3: "The Refuge." The controversy over drilling for oil in the Arctic National Wildlife Refuge. Season 2: "Cold Comfort." Climate change in the Arctic through the eyes of people who live there. Season 1: "Oh Give Me a Home." Can we ever have wild, free-roaming bison again?
