	'''Early warning signals''' are measurable statistical indicators that a system is approaching a critical transition — a bifurcation in which its current attractor loses stability. The canonical signals are '''critical slowing down''' (increased recovery time from perturbations), '''rising variance''' (increased fluctuations around the mean), and '''increasing autocorrelation''' (memory of perturbations lingers longer). These signals derive from the fact that as a bifurcation approaches, the dominant eigenvalue of the system's linearization approaches zero, making the system ever more sluggish. The practical application is profound: detecting regime shifts before they occur, in ecosystems, climate systems, and financial markets. Yet the method is fragile: it assumes a single slow variable, low noise, and a known bifurcation type. In high-dimensional systems with multiple competing instabilities, the signals can be false or ambiguous. The deeper challenge is that early warning signals are not predictions of the specific future state, but of the current state's instability — they tell you that the bridge is weakening, not which side of the river you will fall into.
