A science-focused advocacy organization announced on Tuesday that the metaphorical “Doomsday Clock” has now been set to just 89 seconds until midnight, marking the closest approach to potential catastrophe in its history. This alarming count reflects the organization’s assessment of how near humanity is to facing existential threats.

The Bulletin of the Atomic Scientists made this yearly declaration, attributing the urgency to various critical issues. These include escalating climate change, the spread of nuclear weapons, volatility in the Middle East, the dangers posed by pandemics, and the increasing integration of artificial intelligence into military strategies. Previously, the clock remained at 90 seconds for two successive years, emphasizing the gravity of the situation. Daniel Holz, the chair of the organization’s science and security board, remarked, “When you are at this precipice, the one thing you don’t want to do is take a step forward.”

The advocacy group expressed particular concern over the collaboration among nations like North Korea, Russia, and China in enhancing their nuclear capabilities. Amid ongoing tensions regarding Ukraine, Russian President Vladimir Putin has made threats implying the possible utilization of nuclear weaponry. Holz pointed out, “A lot of the rhetoric is very disturbing,” highlighting a growing fear that a nation may resort to nuclear weapons, which he described as a terrifying prospect.

The symbol of the Doomsday Clock first appeared in 1947 to illustrate the potential threats that humanity faces. During the Cold War’s conclusion, the clock indicated a safer distance of 17 minutes to midnight. However, in response to the swift changes occurring globally in recent years, the organization shifted its focus from minutes to mere seconds, intensifying the sense of urgency.

The group believes that if leaders and nations collaborate effectively to confront these monumental risks, there is hope to turn back the clock and move towards a safer future.
