We are seeding clouds, darkening the sun, and shading the Great Barrier Reef. For proponents, the use of technology to influence weather and climate is a necessary "Plan B" against global warming – for scientists, it remains an incalculable risk. The film explores who is already working on geoengineering technologies, what interests are behind them, and what consequences they could have for climate, politics, and society. A growing number of researchers are now calling for an open discussion about interventions in the atmosphere – between the hope of gaining time and the danger of new global conflicts.

Film screening followed by a discussion with experts.
