Data sets

Global mean CO2, temperature and sea level data from transient model simulations of Quaternary glacial cycles Matteo Willeit, Andrey Ganopolski, Reinhard Calov, and Victor Brovkin

Short summary
The glacial–interglacial cycles of the Quaternary exhibit 41 kyr periodicity before the Mid-Pleistocene Transition (MPT) around 1.2–0.8 Myr ago and ~100 kyr periodicity after that. The mechanism generating these periodicities remains elusive. Through an analysis of an Earth system model of intermediate complexity, CLIMBER-2, we show that the dominant periodicities of glacial cycles can be explained from the viewpoint of synchronization theory.
