Geoengineering

The 2013 documentary "Look Up!" directed by George Barnes addresses the controversial topic of geoengineering and solar radiation management (SRM). The film explores the use of airplanes to spray toxic metals and particles into the atmosphere with the intention of blocking the sun and altering climate patterns, which the film argues creates unknown and potentially dangerous consequences. The documentary features interviews with scientists, airline industry professionals, and government officials, aiming to raise awareness about the potential threats of geoengineering and weather modification programs.
