How we address the climate change crisis today will largely determine what kind of world our young people will inherit. After the U.S. announced its intention to pull out of the Paris Climate Agreement, Jamie Margolin launched Zero Hour, an international youth-led climate action organization. With the mission of centering the voices of diverse youth in the conversation around climate and environmental justice, Zero Hour organizes marches, rallies, climate strikes, mobilizations, lobby days, speaking tours, educational programming, social media campaigns, and summits to bring urgency and awareness to the climate crisis. Zero Hour organized the very first Youth Climate March in Washington, D.C., and 25 other cities around the world, created the Youth Climate Lobby Day, and co-created the first Youth Climate Summit in Miami in the summer of 2019. Jamie has become an instrumental voice in the youth-led climate change movement and is sharing what she’s learned along the way in her book, Youth to Power: Your Voice and How to Use it.
