A few weeks ago, USA Today ran a story with the headline "It's over: 2023 was Earth's hottest year, experts say." But is it really over? Hannah Ritchie, a data scientist at the University of Oxford, doesn't think so. In her new book, "Not the End of the World," she says that if we zoom out and look at the data, "we can see something truly radical, game-changing and life-giving: humanity is in a truly unique position to build a sustainable world." She's on the show today to tell us why she's urgently optimistic about our planet's future, what smart people get wrong about climate change, and the most effective ways to lower your carbon footprint.Host: Caleb BissingerGuest: Hannah RitchieYou can learn more about Our World in Data here, and check out Hannah's newsletter, Sustainability by Numbers.Want to come to our event in New York City on Jan. 31?
