Watch VoirFilms. The Weather War is a documentary/art film about man’s attempts to control the weather and harness it for his own purposes. In a blend of land art performance and road movie, artist duo Bigert & Bergström travel to the US tornado belt with their special machine-sculpture, the Tornado Diverter. The goal: To stop a tornado. Along the way, we see historical examples of how the science of meteorology developed in symbiosis with military goals and how these visions evolved into modern ideas of geo-engineering. Controversial ideas with socio-political consequences, spotlighting the big question of who is really entitled to modified weather.
