Grace chats with Kelsey Skaggs, lawyer and Executive Director of the Climate Defense Project, about suing Harvard for its failure to divest from fossil fuels while still a law student and the growing momentum around the climate necessity defense. They talk about the decades-long campaign by members of the fossil fuel industry and their allies to undermine climate science and disempower the public, and how regular people have found the courage to risk their bodies and their freedom in nonviolent civil disobedience against government and industry policies that worsen the climate crisis.
