On this episode of Now & Then, “Climate Control,” Heather and Joanne discuss the climate crisis and moments of political conflict over the environment throughout American history. They talk about the impact of climate on colonists, the 19th-century origins of the National Park Service, the causes and effects of the Dust Bowl, and the post-World War II emergence of the environmental movement — from Rachel Carson, to nuclear fall-out fears, to the formation of the Environmental Protection Agency. What solutions might these past controversies offer the United States today? Can we reach political consensus on addressing climate change? And who is ultimately responsible for protecting the earth?
