About this episode
The 100th meridian is the longitudinal boundary separating the humid East and the arid West. Researchers say the dry line is moving east because of climate change, threatening some of our cheapest and most reliable crops, like wheat and corn. In this episode, Amy drives across Kansas to talk to farmers on both sides of the dry line to see how they’re adapting to climate change. And we hear from a scientist who’s trying to breed crops that will thrive in a hotter, drier world.
