CLOSE We are creeping closer to the apocalypse, according to a panel of scientists and scholars. Scientists has moved the 'Doomsday Clock,' a symbolic countdown to the end of the world, to two and a half minutes to midnight. USA TODAY

 Scientists moved the hands of the Doomsday Clock closer to midnight on Thursday amid increasing worries over nuclear weapons and climate change. 
  
 Each year, the Bulletin of the Atomic Scientists, a nonprofit that sets the clock, decides whether the events of the previous year pushed humanity closer or further from destruction. The symbolic clock is now two-and-a-half minutes from midnight, the closest it's been to midnight since 1953, when the hydrogen bomb was first tested. Scientists blamed a cocktail of threats ranging from dangerous political rhetoric to the potential of nuclear threat as the catalyst for moving the clock closer towards doomsday. 
  
 “This year’s Clock deliberations felt more urgent than usual…as trusted sources of information came under attack, fake news was on the rise, and words were used by a President-elect of the United States in cavalier and often reckless ways to address the twin threats of nuclear weapons and climate change,” Rachel Bronson, the executive director and publisher of Bulletin of the Atomic Scientists, said in a statement. 
  
 While many threats played into the decision to move the clock 30 seconds forward from where it was in 2016, one person in particular prompted the scientists to act. 
  
 "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," David Titley and Lawrence M. Krauss of the Bulletin wrote in an New York Times op-ed. 
  
 The Bulletin pointed to President Trump's careless rhetoric on nuclear weapons and other issues as well as his troubling stance on climate change. 
  
 “Current political situation in the U.S. is of particular concern,” Titley of the Bulletin Science and Security Board said. “The Trump administration needs to state clearly, unequivocally it accepts climate change caused by human activity…There are no alternative facts here.” 
  
 Last year, the clock remained at three minutes from midnight. It was moved to three minutes in 2015 where it was previously at five minutes to midnight. 
  
 Manhattan Project scientists, concerned about the first atomic weapons, founded the nonprofit Bulletin of the Atomic Scientists in 1945. They created the clock two years later, and update its minute hand each year. 
  
 According to the group, the clock “conveys how close we are to destroying our civilization with dangerous technologies of our own making.” 
  
 The threat of nuclear warfare plays heavily into the time on the clock, as do the dangers of climate change the threat from cyber technology, according to the group’s website. 
  
 The decision is made by the board of the nonprofit Bulletin of the Atomic Scientists' along with input from a board of sponsors which includes 15 Nobel Laureates, according to the group.

 The minute hand on the Doomsday Clock ticked closer to midnight Thursday, as the Bulletin of the Atomic Scientists said it's seeing an increase in dangers to humanity, from climate change to nuclear warfare. The group took the "unprecedented" step of moving the clock 30 seconds closer to midnight, to leave it at 2 1/2 minutes away. 
  
 The setting is the closest the symbolic clock has come to midnight since 1953, when scientists moved it to two minutes from midnight after seeing both the U.S. and the Soviet Union test hydrogen bombs. It remained at that mark until 1960. 
  
 "Make no mistake, this has been a difficult year," Rachel Bronson, executive director and publisher of the Bulletin of the Atomic Scientists, said as the new setting was announced Thursday. 
  
 Explaining its move, the Bulletin's Science and Security Board said: 
  
 "Over the course of 2016, the global security landscape darkened as the international community failed to come effectively to grips with humanity's most pressing existential threats, nuclear weapons and climate change ... This already-threatening world situation was the backdrop for a rise in strident nationalism worldwide in 2016, including in a U.S. presidential campaign during which the eventual victor, Donald Trump, made disturbing comments about the use and proliferation of nuclear weapons and expressed disbelief in the overwhelming scientific consensus on climate change." 
  
 The board criticized President Trump further, saying that "even though he has just now taken office, the president's intemperate statements, lack of openness to expert advice, and questionable cabinet nominations have already made a bad international security situation worse." 
  
 Last year, the Doomsday Clock's setting didn't change from 2015, when it jumped two notches to three minutes before midnight — the closest it had been to midnight since the early era of above-ground hydrogen bomb testing. 
  
 Created in 1947, the Doomsday Clock was conceived by scientists who had participated in the Manhattan Project. Initially seen as an indicator of the likelihood of disastrous nuclear conflict, it now also includes other threats, such as climate change, biological weapons and cyberthreats. 
  
 It's the first time in the Doomsday Clock's 70-year history that the advisory board has adjusted the clock by 30 seconds. 
  
 The decision to advance the clock was announced at the National Press Club, where speakers included board members former U.S. Ambassador to the United Nations Thomas R. Pickering and physicist Lawrence Krauss. A simultaneous event was held at Stanford University that featured California Gov. Jerry Brown, former Secretary of State George Schultz and former Defense Secretary William Perry. 
  
 "Facts are stubborn things," Krauss said, "and they must be taken into account if the future of humanity is to be preserved." 
  
 The Doomsday Clock, physicist Lawrence Krauss said at Thursday's event, offers "a rare opportunity to reach the global public directly." Urging members of the public to speak to their political leaders, he added that important decisions about humanity's future shouldn't be left to a few men. 
  
 "President Trump and President Putin, who claim great respect for each other, can choose to act together as statesmen, or act as petulant children, risking our future," Krauss said. 
  
 His direct comments sparked the first question after board members had made their initial statements, as Tracy Wilkinson of The Los Angeles Times asked Krauss, "You said this shouldn't be left in the hands of one or two leaders making crazy statements. I know you mean Trump, but is the second person Putin?" 
  
 As Krauss answered yes, another panel member, Thomas Pickering, added, "Good guess." |||||
We haven't been this close to doomsday since atomic bombs were detonated in 1953, according to the Doomsday Clock. The clock, used to show "how close we are to destroying our civilization," jumped 30 seconds closer to midnight Wednesday, giving us 2.5 minutes to go, reports USA Today. The Bulletin of the Atomic Scientists put much of the blame on President Trump, who it said "made disturbing comments about the use and proliferation of nuclear weapons and expressed disbelief in the overwhelming scientific consensus on climate change," per NPR. It added that "even though he has just now taken office, the president's intemperate statements, lack of openness to expert advice, and questionable cabinet nominations have already made a bad international security situation worse."
