Zurek, Habib, and Paz (1993) demonstrated that environmental decoherence suppresses quantum interference on timescales far shorter than Ehrenfest time, restoring classical behavior.

Based on where you are in your exploration

Classical behavior(as used in physics and philosophy of physics): The way ordinary objects in everyday life behave—following predictable rules like gravity and motion, rather than the weird probabilistic rules of quantum mechanics.
Ehrenfest time(as used in quantum mechanics): The specific moment or duration after which quantum systems stop behaving like classical systems and start showing their weird quantum properties.
Environmental decoherence(as used in quantum physics and philosophy of physics): The process where a quantum system (something operating by quantum rules) loses its special quantum properties when it interacts with its surroundings, causing it to behave like ordinary everyday objects instead.
Quantum interference(as used in quantum mechanics): A phenomenon where quantum particles can exist in multiple states at once and affect each other in ways that have no everyday equivalent—like waves in water interfering with each other.
Timescales(as used in physics): The characteristic time periods or durations over which something happens—in this case, how quickly the process occurs.
Zurek, Habib, and Paz(as used in quantum physics research): Three physicists who conducted research together; Zurek is particularly famous for developing the theory of how quantum systems interact with their environment to produce classical behavior.
