Experts at The Bulletin of the Atomic Scientists – the organisation behind the clock – moved the clock to 2.5 minutes to midnight as heightened global tension between nations continues to take its toll.
In 2016 and 2015, the Doomsday Clock was positioned at three minutes to midnight, but much of the world is now fearing more war with the election of Donald Trump as the President of the United States.
It is the closest that the Doomsday Clock has been to midnight since 1953 when hydrogen bombs were being tested for the US and Soviet Union.
Lawrence Krauss and David Titley specifically mentioned Donald Trump in a statement as his views on nuclear weapons and climate change could devastate the world.
The Doomsday Clock has moved closer to midnight
Donald Trump recently became the 45th President of the United States
A statement from the organisation read: ”The United States now has a president who has promised to impede progress on both of those fronts.
"Never before has the Bulletin decided to advance the clock largely because of the statements of a single person.
"But when that person is the new president of the United States, his words matter."
The prospect of nuclear war is rising
The experts also say that the threat of nuclear war is mounting: The United States and Russia—which together possess more than 90 percent of the world’s nuclear weapons—remained at odds in a variety of theatres, from Syria to Ukraine to the borders of NATO; both countries continued wide-ranging modernisations of their nuclear forces, and serious arms control negotiations were nowhere to be seen.
“North Korea conducted its fourth and fifth underground nuclear tests and gave every indication it would continue to develop nuclear weapons delivery capabilities.
“Threats of nuclear warfare hung in the background as Pakistan and India faced each other warily across the Line of Control in Kashmir after militants attacked two Indian army bases.”
