Cold War nuclear scares, asteroid airbursts, supervolcanoes. These are not sci-fi. Quartz frames them as 15 moments when the world “almost ended,” and then asks a practical question underneath the drama: what stopped it?

Here is the payoff. In every case Quartz points to a mix of decisions, luck, and the stubborn logic of physics that narrowed the blast radius before it widened into something irreversible. The lesson is not “be grateful.” It is “understand where your organization depends on the same kinds of guardrails.” In high-stakes systems, catastrophes rarely require a single villain. They require multiple failures, and sometimes the failures do not line up, because humans built, maintained, tested, or constrained the system in just enough places.

Start with the Cold War nuclear scares. These events sit in the gray zone between human error and technological risk, where a single misread could cascade into automated action. Historically, nuclear command and control has been designed around multiple layers because incentives and fear are not reliable safety mechanisms. A launch decision is not supposed to be a gut check. It is a process, with rules, verification, and communications that must stay synchronized under stress. Quartz’s compilation highlights the near misses because they expose the uncomfortable truth: even with safeguards, organizations operate near the edge when the cost of hesitation is high and the cost of acting wrongly is catastrophic. That is exactly where second-order risk lives, in how people interpret ambiguous signals and how systems respond when interpretation is wrong.

Then shift to the sky. Quartz includes asteroid airbursts, a reminder that nature can threaten from outside the chain of command. Unlike nuclear scares, where the failure can be internal, an asteroid event is external, but the response is still institutional. The difference matters for leaders: you cannot “negotiate” with a cosmic object. What you can do is build discovery, monitoring, modeling, and communication processes that turn uncertainty into decisions fast enough for them to matter. Quartz’s premise that physics and luck can save us does not remove the need for preparedness. It changes the way you think about it. If the decisive factor is early detection plus an action window, then delay is not just an inconvenience. It is a deal-breaker.

Supervolcanoes add another dimension: scale. A supervolcano is not a single catastrophic moment in the same way as a launch decision, because the danger is broad, atmospheric, and persistent. The risk shows up as downstream effects: climate disruption, agriculture stress, economic contraction, and political volatility. Quartz’s inclusion of supervolcanoes makes a key point for boards: even if your company never touches volcanic hazard models directly, extreme environment risks can still hit your supply chain, your insurance costs, and your demand curve. The second-order effect is that “low frequency” can still produce “high harm,” especially when global systems are already brittle.

What Quartz is really doing by stitching these 15 scenarios together is mapping how catastrophe is prevented. Sometimes the stop is a deliberate choice, like procedural safeguards and decision rules that prevent the wrong action. Sometimes it is luck, where multiple uncertainties do not line up. Sometimes it is physics, where the energy, timing, and trajectories prevent full escalation. The important strategic stake for executives is that you cannot manage what you cannot see, and you cannot reliably see what is dispersed across people, technology, and incentives.

For leaders in regulated industries, this looks familiar. Regulatory frameworks exist to reduce failure modes, to require documentation and testing, and to create accountability when systems break. But regulation is not a magic spell, it is an input into organizational behavior. Quartz’s theme suggests a more operational takeaway: the organizations most likely to avoid disaster are those that treat edge cases as real, exercise their response plans, and build redundancy into interpretation, communication, and execution. If you are a CEO, CFO, or board member, your job is to ask the boring questions early: where are we dependent on correct interpretation? Which steps have the biggest consequences if they fail? And what assumptions are we making about time, signal quality, and the “physics” of our own system that could be wrong.

The world has not ended yet, and Quartz’s list is a catalog of why that might be. The strategic implication is that “almost” is not comfort. It is data. Use it to audit your own system for the places where luck is doing the work that leadership and design should be doing.
