又推进4秒，“末日之钟”倒计时只剩85秒

Core Viewpoint - The "Doomsday Clock" has been moved to 85 seconds to midnight, marking the most dangerous level in nearly 80 years, reflecting escalating global risks, particularly nuclear threats and geopolitical tensions [1][3]. Group 1: Doomsday Clock Mechanism - The "Doomsday Clock" was established in 1947 by scientists who developed the first atomic bomb, serving as a warning mechanism for global risks such as nuclear threats and climate change [3]. - The clock's time is adjusted annually based on the perceived existential risks faced by humanity, with the current adjustment reflecting a worsening situation [3]. Group 2: Global Risks and Concerns - The publication's head, Bell, indicated that any government adopting a new imperialistic governance model would push the clock closer to midnight, highlighting the lack of improvement in nuclear risks by 2025 [3]. - Concerns were raised regarding the resurgence of nuclear testing threats, the ongoing Russia-Ukraine conflict, escalating tensions in the Middle East, and the spread of misinformation through artificial intelligence [3][4]. Group 3: Geopolitical Tensions - Since Trump's return to the White House, geopolitical tensions in the Western Hemisphere have intensified, with actions perceived as undermining the existing international order [4]. - Specific actions include the forced control of Venezuelan President Maduro and threats against other Latin American countries, which have damaged transatlantic security cooperation [4]. Group 4: Symbolic Nature of the Clock - The "Doomsday Clock" serves as a symbolic mechanism aimed at raising public awareness of global crises, although some experts have questioned its effectiveness as a metaphor [4]. - Historical context shows that the clock can be reset; for instance, it was moved back to 23:43 in 1991 after the signing of the Strategic Arms Reduction Treaty [4].
