Group 1: Doomsday Clock Mechanism - The "Doomsday Clock" was established in 1947 by scientists who developed the first atomic bomb, serving as a warning mechanism for global risks such as nuclear threats and climate change [3]. - The clock's time is adjusted annually based on the perceived existential risks faced by humanity, with the current adjustment reflecting a worsening situation [3].
