Created by the members of the Bulletin of the Atomic Scientists, the doomsday clock represents the likelihood of a man-made global catastrophe for humanity. Parameters are politics, nuclear war, climate change and other developments that put mankind at risk.
The potential risk is shown in the numbers of minutes until midnight. In 2018 the clock was set to 2 minutes to midnight. The explanation came in the following statement:
The failure of world leaders to address the largest threats to humanity’s future is lamentable—but that failure can be reversed. It is two minutes to midnight, but the Doomsday Clock has ticked away from midnight in the past, and during the next year, the world can again move it further from apocalypse. The warning the Science and Security Board now sends is clear, the danger obvious and imminent. The opportunity to reduce the danger is equally clear. The world has seen the threat posed by the misuse of information technology and witnessed the vulnerability of democracies to disinformation. But there is a flip side to the abuse of social media. Leaders react when citizens insist they do so, and citizens around the world can use the power of the internet to improve the long-term prospects of their children and grandchildren. They can insist on facts, and discount nonsense. They can demand action to reduce the existential threat of nuclear war and unchecked climate change. They can seize the opportunity to make a safer and saner world.
