Fig. 2: Residuals between the modelled global ice volume and the reconstructed global ice volume changes.
From: A gradual change is more likely to have caused the Mid-Pleistocene Transition than an abrupt event

The reconstructed global ice volume is from ref. 41. ORB (a), ABR (b) and GRAD (c) simulations. Yellow and red areas are time intervals where the model-data deviation exceeds 30 m.
