The Doomsday Clock, maintained by the Bulletin of the Atomic Scientists since 1947, is a metaphorical representation of the likelihood of a catastrophic global event, particularly nuclear warfare. The clock’s minute hand is adjusted every year based on scientific analyses, international relations, and global policies. In 2022, the minute hand has been moved further to 90 seconds before midnight, reflecting the increased concern regarding looming threats to humanity. The proximity to midnight in the 2023 update reflects mounting tensions and ongoing challenges, such as climate change and emerging technologies, that scientists believe could lead to devastating global consequences.
The core concerns driving the 2025 Doomsday Clock include the deterioration of international nuclear treaties, the ongoing climate crisis causing unpredictable ramifications, and the rapid advancements in genetic engineering and AI technology. Although climate change remains the most severe contemporary threat to humanity, the international community faces significant challenges in overcoming geopolitical disputes, human rights abuses, and economic instability.
