Researchers from the Mann Research Group found strong path dependence in Plio-Pleistocene glaciations, driven by a gradual decrease in regolith and volcanic outgassing. The study suggests that carbon dioxide levels determine the onset of the Mid-Pleistocene Transition, and that it's not too late to act to prevent ice sheet collapse.
