Pleistocene sea-surface temperature evolution: Early cooling, delayed glacial intensification, and implications for the mid-Pleistocene climate transition
The mid-Pleistocene climate transition (MPT) is defined by the emergence of high amplitude,
quasi-100ka glacial–interglacial cycles from a prior regime of more subtle 41kacycles. This …
