The symbolic Doomsday Clock, a global warning signal watched around the world, has moved closer to midnight than ever before. For 2026, scientists have set the clock at 85 seconds to midnight, marking the most serious warning since the clock was first created in 1947. Midnight represents global catastrophe, and the current setting shows how worried experts are about the direction the world is heading.
The clock is maintained by a group of scientists who study nuclear dangers, climate risks, and emerging technologies. Each year, they review global events and decide whether humanity is moving toward safety or danger. This year’s decision reflects deep concern that global threats are growing while cooperation between countries is weakening.
According to the scientists, the risks facing humanity are no longer limited to one area. Nuclear weapons, climate change, biological threats, and artificial intelligence are now overlapping. Together, they create a dangerous mix that could push the world toward irreversible harm if not addressed quickly.
What the Doomsday Clock represents
The Doomsday Clock is not a real clock. Instead, it is a symbol designed to help the public understand how close humanity is to self-destruction. When the clock moves closer to midnight, it signals greater danger and when it moves away, it suggests progress toward safety.
When the clock was first introduced in 1947, it stood at seven minutes to midnight. At that time, nuclear weapons were new, and the world was still learning how dangerous they could be. Over the decades, the clock has moved back and forth based on global conditions.
The safest moment ever recorded was in 1991. That year, the Cold War ended, and major nuclear powers began cutting their nuclear weapons. The clock was set at 17 minutes to midnight, showing hope for a safer future.
However, history also shows how quickly things can worsen. In 1984, the clock was set at just three minutes to midnight. During that period, communication between major powers had nearly stopped, and nuclear tensions were high.
In recent years, the clock has steadily moved closer to midnight again. Scientists now say that nuclear danger is no longer the only threat. Climate change has become a central concern, along with new risks linked to modern technology. This combination has pushed the clock to its most alarming position yet.
Rising global tensions and conflict
One of the main reasons for moving the clock closer is the rise in global conflict. Scientists point to growing aggression and nationalism among powerful countries. Instead of working together, many nations are acting alone and competing for dominance.
Several major conflicts during 2025 played a role in this assessment. The ongoing war in Ukraine continued to destabilize global security. At the same time, clashes between India and Pakistan erupted in May, raising fears due to the history of tension between the two neighbors. In June, military strikes involving the United States, Israel, and Iran added another layer of instability in an already volatile region.

These conflicts matter because they involve countries with advanced weapons and strong military power. When tensions rise between such nations, the risk of wider confrontation also increases. Scientists warn that misunderstandings or sudden decisions could escalate quickly.
Another concern is the collapse of long-standing international agreements. Over many years, countries worked together to reduce nuclear risks and build trust. According to the scientists, many of these agreements are now weakening or disappearing. In their place, a “winner-takes-all” mindset is emerging, where cooperation is replaced by rivalry.
This shift makes the world more dangerous. Global problems, such as nuclear weapons and climate change, cannot be solved by one country alone. Without trust and shared rules, managing these threats becomes far more difficult.
Climate crisis and energy contradictions
Climate change is another major reason the clock moved closer to midnight. Scientists say that responses to the climate emergency have been deeply inadequate. In some cases, policies have even made the situation worse.
Recent international climate meetings failed to clearly focus on reducing fossil fuel use or closely tracking carbon dioxide emissions. This lack of strong action worries experts, as global temperatures continue to rise and extreme weather becomes more common.

At the national level, some governments have rolled back climate policies. Scientists note that resistance to renewable energy and climate action in certain countries has slowed progress at a time when faster action is needed.
At the same time, the picture is not entirely negative. Renewable energy, especially wind and solar power, reached record levels of growth in 2024. More clean energy plants were built, and they produced more electricity than ever before.
For the first time, renewable energy and nuclear power together generated more than 40 percent of the world’s electricity. This milestone shows that cleaner energy systems are expanding and becoming more important in the global energy mix.
However, scientists stress that progress in energy production does not cancel out the broader risks. Climate change continues to threaten food systems, water supplies, and human health. Without strong global coordination, even positive developments may not be enough to prevent serious damage.
The scientists behind the Doomsday Clock also highlight emerging dangers from biotechnology and artificial intelligence. These technologies can bring benefits, but they also carry risks if misused or poorly controlled. In a world already divided by conflict, new tools can increase uncertainty and fear.
Overall, the clock’s new setting sends a clear message. Humanity is facing multiple, overlapping threats at the same time. Nuclear tension, climate failure, and rapid technological change are all moving faster than global efforts to manage them. The Doomsday Clock stands as a warning that the margin for error is shrinking, and the consequences of inaction are becoming harder to ignore.
