Doomsday clock ticks one second, closest ever to midnight

The Doomsday Clock, a symbolic measure of humanity's proximity to destruction, was moved to 89 seconds to midnight on Tuesday—the closest it has ever been.

The adjustment reflects growing fears of nuclear conflict, escalating climate crises, and the widespread impact of disinformation. The clock, created by the Bulletin of the Atomic Scientists in 1947, has served as a barometer of existential risks.

"At 89 seconds to midnight, the clock stands closer to catastrophe than at any moment in its history," said Juan Manuel Santos, former Colombian president and chair of The Elders, a group of global leaders.

Global threats and leadership

Santos called for unity and bold action, emphasizing the urgent need to reverse the dangerous trajectory. He criticized the divisive effects of disinformation, which he said undermines trust and worsens global challenges.

"This alarming rise in distrust is being fueled in large part by the reckless use of new technologies we do not yet fully understand," Santos said.

The Doomsday Clock was last moved in 2022 to 90 seconds to midnight following Russia's invasion of Ukraine, which reignited fears of nuclear escalation.

The board of experts also highlighted the dire consequences of climate change. Recent years have seen record-breaking global temperatures and environmental crises.

Santos noted that efforts to combat climate change and foster international cooperation face challenges from the amplification of conspiracy theories and the spread of misinformation online.

While Santos welcomed diplomatic overtures toward Russia and China, he criticized policies such as the withdrawal from the Paris Climate Accord and the World Health Organization, signaling concerns over weakened global collaboration.

The Doomsday Clock, initially set at seven minutes to midnight, reflects humanity's urgent need to address existential threats with decisive leadership and cooperative action.
