Scientists moved the hands of the Doomsday Clock around midnight on Thursday amid concerns about nuclear weapons and climate change.
The clock is now two minutes at midnight.
Each year, the Bulletin of the Atomic Scientists, a nonprofit group that sets the clock, decides whether the events of the previous year pushed humanity closer or further from the destruction.
The symbolic clock is now the closest to midnight since 1953. It was also two minutes to midnight in 1953 when the hydrogen bomb was first tested.
"We made the clear statement that we feel the world is becoming more dangerous," said Lawrence Krauss, chairman of the Bulletin Board of Sponsors. He added that "the danger of nuclear conflagration is not the only reason why the clock has advanced".
The announcement was made in Washington, D.C., at the National Press Club.
Scientists blamed a cocktail of threats ranging from dangerous political rhetoric to the potential of a nuclear threat as catalysts to bring the clock closer to doomsday.
The statement explaining the restoration of the time of the notes of the final judgment: In 2017, world leaders did not respond effectively to the imminent threats of nuclear war and climate change, making the global security situation more dangerous than it was a year ago, and as dangerous as it has been since World War II.
"The biggest risks in the nuclear field came last year." North Korea's nuclear weapons program appeared to make significant progress in 2017, increasing the risks to itself, to other countries in the region and to the United States.
"Hyperbolic rhetoric and provocative actions on both sides have increased the possibility of a nuclear war by accident or miscalculation.
"On the climate change front, the danger may seem less immediate, but avoiding catastrophic temperature increases in the long term requires urgent attention now, the nations of the world will have to significantly reduce their greenhouse gas emissions for keep climate risks manageable, and so far, the global response has not been enough to meet this challenge. "
The closer it gets to midnight, the closer it is estimated that a global disaster will occur. The furthest it has been until midnight was in 1991, when the Cold War ended when the clock read 17 minutes until midnight.
watch was maintained by the Bulletin of the Atomic Scientists since 1947. The group was founded in 1945 by scientists from the University of Chicago who had helped develop the first nuclear weapons in the Manhattan Project.
Scientists created the clock in 1947 using images of the Apocalypse (midnight) and the contemporary expression of the nuclear explosion (countdown to zero) to transmit threats to humanity and the Earth.
