The Bulletin of the Atomic Scientists was established in 1945 by scientists, engineers, and other experts who had created the atomic bomb as part of the Manhattan Project. They knew about the horrible effects of these new weapons and devoted themselves to warning the public about the consequences of using them. Today, the Bulletin informs the public about threats to the survival and development of humanity from nuclear weapons, climate change, and emerging technologies in the life sciences. Through an award-winning magazine, our online presence, and the Doomsday Clock, we reach policy leaders and audiences around the world with information and analysis about efforts to address the dangers and prevent catastrophe.

Those threats now include climate change and emerging technologies.
