In her first extended broadcast interview in the United States, we spend the hour with Greta Thunberg, the 16-year-old Swedish climate activist who has inspired millions across the globe. Last year she launched a school strike for the climate, skipping school every Friday to stand in front of the Swedish parliament, demanding action to prevent catastrophic climate change. Her protest spread, quickly going global. Hundreds of thousands of schoolchildren around the globe have participated in their own local school strikes for the climate. Since her strike began in 2018, Greta has become a leading figure in the climate justice movement.
