The Doomsday Clock officially struck in 20 seconds, taking the world closer apocalypse.
The new hands are now set at 100 seconds to midnight.
The most worrying is that if we continue to lose 20 seconds a year, that would mean the apocalypse in 2025.
The Bulletin of Atomic Scientists revealed the news during a conference this afternoon, after spending the past six months debating the decision with the Bulletin Sponsor Council, which includes 13 Nobel Prize winners.
The clock was designed to alert the public to how close we are to destroying the world with dangerous technologies, including nuclear weapons and climate change.
Rachel Bronson, President and CEO of the Bulletin, said: "Nuclear and climate conditions are getting worse. It would be a privilege and pleasure to move the hands backwards, but that is not the case."
The Bulletin finds the "inaction of international leaders", as well as their "counterproductive conditions".
He explained: "Given the inaction – and in many cases counterproductive actions – of international leaders, members of the Science and Security Council are required to declare a state of emergency that requires immediate, focused and relentless attention from around the world. seconds to midnight. The clock continues to tick. Immediate action is needed. "
Based on the change, The Bulletin asks US citizens to demand climate action from the US government.
He added: "US citizens must demand climate action from their government. Climate change is a serious and aggravating threat to humanity.
"Citizens must insist that their government recognize it and act accordingly. President Trump's decision to withdraw the United States from the Paris climate change agreement was a serious mistake.
"Whoever wins the U.S. presidential election in 2020 must reverse that decision."
The Doomsday Clock did not move in 2019 and was last postponed in January 2018.
At that time, the clock moved 30 seconds to two minutes before midnight – the closest it had been to the apocalypse since 1953.
The Doomsday Clock was created by the Bulletin of Atomic Scientists in 1947 and was designed to alert the public to how close we are to destroying the world with dangerous technologies.
When it was created, the greatest danger to humanity came from nuclear weapons – mainly from the perspective of a nuclear arms race between the United States and the Soviet Union.
However, in 2007, catastrophic disruptions to climate change also began to be considered by the Bulletin of Atomic Scientists.
In the early days, Eugene Rabinowitch, editor of the Bulletin of Atomic Scientists, decided when the minute hand should be moved, explaining its logic on the pages of the Bulletin.
However, when Rabinowitch died in 1973, the Bulletin's Science and Security Council took responsibility and has since met twice a year to discuss whether the clock needs to be reset.
The council is made up of scientists and other experts with extensive knowledge of nuclear technology and climate science.
However, the group regularly seeks the views of the Bulletin Sponsors Council, which includes 13 new winners.
While the hands of the clock are currently in the closet from 2 minutes to midnight, they were further away in 1991.
That year, the US and the Soviet Union signed a Strategic Arms Reduction Treaty, prompting the Bulletin to adjust the clock to 17 minutes to midnight.
