Peter Kirby is a researcher, writer, and activist based in San Rafael, California. Born in 1971 in San Francisco and raised in nearby Brisbane, California, he has a background in radio, television, and film, having studied at Cal State Long Beach and San Francisco State. Since 2009, Kirby has focused extensively on researching and writing about geoengineering. Kirby is the author of Chemtrails Exposed: A New Manhattan Project, a book in which he argues that a large-scale, covert scientific program—akin to the original Manhattan Project—is responsible for a plurality of projects that are impacting the earth’s climate. He asserts that this operation involves major institutions, and is backed by significant funding and numerous patents. His work suggests that these activities are hidden from the public through a mass-disinformation campaign. Kirby has collected significant evidence tying elevated levels of toxins like aluminum and barium in rainwater and air samples to geoengineering activities.
