regime shift

A regime shift refers to a significant, long-lasting change in the behavior or state of a system, such as an ecosystem, economy, or climate, due to internal or external factors. It’s like a system reaching a tipping point, after which it transitions to a different mode that remains stable for a long period. For example, a lake might shift from clear to murky water due to nutrient increases, or a financial market might move from steady growth to a recession. These shifts can be difficult to reverse and often indicate a fundamental change in the system’s structure.
