Climate Scientist and TED Talker Katharine Hayhoe is equally interested in the obvious ecological collapse as she is in how to talk so people will listen. She and Kelly break down the moves and messages that do and don't work when trying to change global attitudes and save our planet. Kelly's 17 year-old Claire jumps in to talk about the power of Planet Earth and protests and stories of extinction. Follow the conversation on Instagram @kellycorrigan.
