Predictions of tipping points in ecology, climate change, medical outcomes and other complex systems are a primary goal for many researchers. The pursuit of insights into the timing of critical transitions is no easy way to make a living, particularly because random events can trigger such changes and warning signs are easily missed or misinterpreted.Perhaps the best approach to studying tipping points is to combine two different approaches—one that explores the architecture of systems that change drastically and another that homes in on telltale signs that a system is on the brink...
