The Bulletin of the Atomic Scientists warned people about the impending disaster when they unveiled that "Doomsday Clock" on Tuesday. The clock counts down to the worldwide catastrophe that will happen in the future due to various reasons like tensions between nations, nuclear testing and climate change, per the Associated Press.

The "Doomsday Clock" is three minutes close to midnight where midnight marks the start of the apocalypse. The last time the minutes were three minutes before midnight was back in 1984 during the Cold War while it reached two-minutes-to-midnight in 1953 when the United States and the Soviet Union tested hydrogen bombs.

"Unless we change the way we think, humanity remains in serious danger," Lawrence Krauss, Chairman of the Board of Sponsors said.

Krauss added that the newly implemented nuclear agreement with Iran and the Paris climate change treaty are a good start, but there are several factors that are still capable of overpowering these measures. He listed the ongoing tension between India and Pakistan, North Korea's nuclear testing and the lack of concrete actions to lessen the amount of emitted greenhouse gasses.

Former U.S. Secretary of Defense William Perry noted that the threat of a nuclear war is far serious at the present day while former U.S. Secretary of State George Shultz suggested the need for the U.S. to take on Russia and China.

However, Skeptic Magazine's Michael Shermer has described the "Doomsday Clock" as cynical and just a public relations move since it started. Shermer is not the only skeptic of the metaphorical clock as former TIME writer Michael D. Lemonick also is not a fan.

"Whenever Doomsday Clock time rolls around, I roll my eyes, because the Clock doesn't actually gauge anything measurable. The various threats the Clock concerns itself with nuclear war and climate change are the biggies have completely different timescales. It's more truthiness than truth," Lemonick wrote in the Scientific American.

"The Doomsday Clock is anything more than an excuse for concerned scientists to remind us about the dangerous technology we've created. Let us not pretend, however, that these threats can actually be measured in any meaningful way," he added.

According to the official website of The Bulletin of the Atomic Scientists, the "Doomsday Clock" is designed to show how close the human race is in destroying the world by the things he created. It recognizes nuclear weapons, climate change, biotechnology and emerging technologies as the trigger that will start the downfall of civilization. The clock was created in 1947 by scientists who were part of the Manhattan Project.
