Sensitivity of simulations of Plio–Pleistocene climate with the CLIMBER-2 Earth System Model to details of the global carbon cycle

In a new study led by former Mann Research Group postdoctoral researcher, Judit Carrillo, path dependence was reassessed in the history of glacial/interglacial cycles over the past 3 million years. We expand on our 2024 PNAS article to demonstrate that path dependence (or hysteresis) is highly threshold-dependent based on the model’s global carbon cycle.
