“末日时钟”（Doomsday Clock）是由《原子科学家公报》于1947年设立的象征性时钟，用于警示人类面临全球性灾难（尤其是核威胁与气候变化）的紧迫程度。2023年1月，该时钟被拨快至距“末日”仅剩90秒，为历史上最接近终点的时刻，较2020年拨快了4秒。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、生物安全威胁以及虚假信息扩散等因素。科学家警告，人类正在走向危险边缘，各国亟需加强合作，控制核扩散、加速能源转型并建立全球危机应对机制。“末日时钟”并非预测工具，而是通过科学共识呼吁人类正视危机、减少自身制造的风险。它提醒我们：人类的未来仍掌握在自己手中。
The Doomsday Clock, established by the Bulletin of the Atomic Scientists in 1947, is a symbolic instrument that represents humanity’s proximity to global catastrophe—particularly from nuclear threats and climate change. In January 2023, the clock was set to 90 seconds to midnight, the closest it has ever been to symbolic doom, advanced by 4 seconds since 2020.This adjustment reflects heightened risks from the Russia-Ukraine conflict, worsening climate disruptions, biological threats, and the spread of disinformation. Scientists emphasize that humanity is moving dangerously closer to self-destruction and urge international cooperation to curb nuclear proliferation, accelerate clean energy transition, and strengthen global crisis management mechanisms.The Doomsday Clock is not a prediction but a call to action based on scientific consensus. It serves as a powerful reminder: our future remains in human hands.
