The Doomsday Clock, created by the Bulletin of the Atomic Scientists in 1947, is a symbolic timepiece representing humanity’s proximity to global catastrophe, particularly from nuclear war and climate change. In January 2023, it was set to 90 seconds to midnight—the closest ever to existential threat—reflecting unprecedented risks.This adjustment was driven by escalating nuclear tensions in the Ukraine conflict, worsening climate emergencies, misuse of biological technologies, and the spread of disinformation. Scientists emphasize that the Clock is not a prediction but a urgent call to action, urging governments and the public to prioritize diplomacy, emissions reduction, and regulatory oversight to avert disaster.Each movement of the Doomsday Clock serves as a stark reminder: the future remains in our hands, yet time is running critically short.
“末日时钟”（Doomsday Clock）是一个由《原子科学家公报》于1947年创建的象征性时钟，用于警示人类面临全球性灾难（尤其是核战争与气候变化）的紧迫性。2023年1月，该时钟被拨快至离午夜仅剩90秒，创下历史最近距离，标志着人类生存威胁达到空前水平。这一调整主要基于俄乌冲突加剧核风险、气候危机持续恶化、生物技术滥用及虚假信息扩散等多重因素。科学家强调，时钟的变动并非预测，而是呼吁各国政府与公众立即采取行动，通过外交对话、减排承诺和技术监管来规避灾难。“末日时钟”的每一次拨动，都是对人类文明存续的深刻反思，提醒我们：未来仍可改变，但时间已然紧迫。
