From the streets of Brooklyn to the forests of Siberia, a relentless barrage of fires, floods, and storms made devastatingly clear that the extreme weather climate scientists had been predicting for half a century had arrived. In a production of unprecedented scope, the film chronicles that pivotal year through the eyes of everyday people around the world. Built out of thousands of hours of in-the-moment footage. At once epic and intimate, the film is a wake-up call to the world from the world.
