In a world where climate change is no longer a distant threat but a harsh reality, scientists and engineers are looking to radical solutions in order to avoid an irreversible collapse of the environment. In this gripping and informative documentary, science journalist Ingolf Baur embarks on a journey across the world to meet with leading researchers in the field of geoengineering, as they explore the feasibility and risks of implementing cutting-edge technologies to avert the worst effects of global warming.
In Switzerland, Iceland, the US, and Peru, Baur encounters two very different approaches to geoengineering: one seeks to remove CO2 from the atmosphere, while the other proposes to dim sunlight. In this thought-provoking documentary, viewers will travel with Baur and witness firsthand the groundbreaking experiments and technologies that could literally change the world. From fleets of aircraft dumping millions of tons of sulfur into the stratosphere, to researchers filtering carbon dioxide from the air and turning it into stone, the documentary explores the risks and possibilities of these radical technologies, offering viewers an unprecedented glimpse into the future of climate change research.
