Description

Climate development from the early Cenozoic greenhouse to the late Cenozoic icehouse world,

documented by changes in deep-ocean temperature (Lear et al., 2000), the decline of atmospheric carbon dioxide (Pagani et al., 2005), global sea-level fluctuations (Miller et al., 2005), and changes in global ice volume (Lear et al., 2000). After the climate optimum in the early Eocene three distinct steps of climate cooling and ice-sheet growth occurred around the Eocene-Oligocene boundary at 34 Ma, in the middle Miocene after 15 Ma, and in the late Pliocene after 2.7 Ma.
