In January 2026 the Bulletin of the Atomic Scientists moved the Doomsday Clock to 85 seconds to midnight, the closest it has ever been in nearly 80 years. This episode traces the symbol from its 1947 origin among Manhattan Project scientists in Chicago, through the artist who set the first cover at seven minutes for purely aesthetic reasons, to the 1949 Soviet bomb test, the 1953 hydrogen bomb drop to two minutes, and the 1991 high point of 17 minutes after the START treaty and the Soviet collapse.

We then follow the clock into the era of seconds: the 2007 addition of climate change, the 2020 shift to 100 seconds, the Ukraine invasion, the militarization of AI, the expiration of New START in February 2026, and the crises the board cited this year. Finally we explore the growing critique from Steven Pinker, Anders Sandberg, journalist James Ball and others who argue the clock breeds paralysis and doom fatigue rather than action, and ask whether the check engine light for humanity still works.

• Why the clock was designed as a gauge of systemic risk, not a real-time speedometer of daily events
• How hydrogen bombs, START verification and the fall of the Berlin Wall moved the hands over the Cold War
• The 2026 drivers: Ukraine, strikes on Iran, India-Pakistan clashes, Korea and the loss of arms-control inspections
• How AI in early-warning systems and disinformation act as accelerants to nuclear risk
• The Cuban Missile Crisis paradox, the doomsday cult accusation and the psychology of doom fatigue
