A 4-second change in the Doomsday Clock by scientists has moved the world as close to midnight as the figurative timepiece has ever been, now just 85 seconds from the possible destruction of humanity. “It’s very significant and we need to listen to [the scientists],” Helfand said in a phone interview. The presentation had members of the organization explain that the Doomsday Clock, first unveiled in 1945, was moving forward because of the various concerns and the lack of response from leaders across the globe. “It’s really unprecedented the level of military activities by countries that possess nuclear weapons,” Helfand said. The Nuclear Freeze movement successfully got leaders to the treaty for the verifiable halt to testing, production and deployment of nuclear weapons.
