"Doomsday Clock" remaining time transition

The "Doomsday Clock" has been published by American scientific journals since 1947 to warn about the threat of nuclear war. It has been.



In 1947, when it was first announced, it was said that there was "7 minutes left" until "The Last Days of Mankind". It was the shortest "remaining 2 minutes" until then.



From the 1960s to the 1970s, there was a time when international treaties aimed at nuclear disarmament came into effect, but from the latter half of the 1970s to the 1980s, the Soviet Union invaded Afghanistan. deepened, and in 1984 it was returned to "3 minutes remaining".



After that, as the cold war ended and the momentum for nuclear disarmament increased, in 1991 there was "17 minutes left", and "the last day of mankind" was the furthest it had ever been.



However, since then, in addition to nuclear threats such as nuclear development by North Korea and Iran, the hands of the "Doomsday Clock" have progressed due to climate change and the spread of new coronavirus infections, and the period from 2020 to last year is three years. It was the shortest 'remaining 1 minute and 40 seconds' so far in a row.
