Horizon Clock monitors the world's biggest threats in real time and turns them into a single number: seconds to midnight. The closer to zero, the more dangerous the world is right now.
We live in a world where a disease outbreak in one country can become a global pandemic in weeks. A cyberattack on a power grid can leave millions without electricity. An economic shock in one market can trigger a chain reaction across the planet. Wars start, volcanoes erupt, floods devastate entire regions , and most of the time, we only hear about these things after they've already escalated.
The information exists. Governments and international organizations track earthquakes, monitor natural disasters from space, report disease outbreaks, and maintain databases for armed conflicts, nuclear activity, cybersecurity breaches, and economic indicators. But all of this data lives in separate places, updated at different speeds, in different formats, for different audiences.
There's no single place where you can look and understand: right now, how bad are things? That's the question Horizon Clock tries to answer.
In 1947, a group of scientists who had worked on the Manhattan Project created the Doomsday Clock , a symbolic clock that represents how close humanity is to destroying itself. When the clock moves closer to midnight, it means the world is in greater danger. It's been one of the most powerful metaphors of the last century.
We deeply respect that work. Horizon Clock is not a replacement , it's a complement. The Doomsday Clock provides an annual assessment based on the judgment of some of the world's most respected scientists and experts. That kind of deep, considered analysis is invaluable and irreplaceable.
What Horizon Clock adds is a different lens: a data-driven, real-time reading that updates every day and covers a broader range of threats. Think of it as a daily pulse check alongside the annual physical. The Doomsday Clock tells you the big picture. Horizon Clock shows you what's happening right now.
Together, they give you a more complete understanding of where the world stands.
Every day, Horizon Clock automatically collects data from multiple trusted sources around the world. Earthquakes, volcanic eruptions, wildfires, floods, disease outbreaks, armed conflicts, nuclear activity, cyberattacks, geopolitical tensions, economic crises , anything that could threaten human safety on a large scale.
Because multiple sources sometimes report the same event, AI helps identify duplicates and group related reports together. Then each event receives a severity score from 0 to 100, based on factors like how many people are affected, how much damage has occurred, and whether the situation is escalating or stabilizing.
When multiple independent sources confirm the same event, the score carries more weight. When something comes from only a single source, it's treated with more caution. This way, the system rewards verified, corroborated information over rumors.
All individual scores are then weighted and combined into a single composite number, which is translated into the clock you see: seconds to midnight. More active and severe threats push the clock closer to zero. Quieter periods push it further away.
We group every threat into one of six categories. Each category has its own weight in the final score, because not all risks are equal , a nuclear incident carries different implications than an economic downturn.
Horizon Clock is not a prediction tool. It doesn't tell you what's going to happen , it tells you what's happening now and how severe it is compared to recent history.
It's also not a replacement for expert analysis, journalism, or institutional decision-making. The score is informational. It can help you stay aware, start a conversation, or contextualize the news , but it should never be the sole basis for any serious decision.
The world is complex. No single number can capture all of it. But a single number can make you pay attention , and sometimes, that's enough.
Horizon Clock is just getting started. Here's where we're heading:
Daily automated updates with global event scoring, Six risk categories with weighted composite score, Interactive 3D globe and clock visualizations, Community Terrain — collaborative intelligence with geo-located markers and sources, User accounts with feedback system
Real-time updates instead of daily, Historical timeline, see how the score has changed over time, Regional breakdowns, zoom into specific parts of the world, Push alerts when the score crosses critical thresholds
Forecasting, where is the score likely heading?, Public API for researchers, journalists, and developers, Deeper category analysis with event-level detail, Maritime and supply-chain monitoring
Priorities can shift as the project evolves. What matters most is making global risk information more accessible to everyone.
Horizon Clock is an open-source project.
