Record #123704:

A first-order global model of Late Cenozoic climate change: orbital forcing as a "pacemaker" of the ice ages / Barry Saltzman.

Title: A first-order global model of Late Cenozoic climate change: orbital forcing as a "pacemaker" of the ice ages / Barry Saltzman.
Author(s): Saltzman, Barry.
Date: 1993.
Publisher: Washington, DC: National Aeronautics and Space Administration
Abstract: Theory of development of Quaternary climate is incomplete unless embedded in more general theory for fuller Cenozoic that can accommodate onset of ice-age fluctuations. Constructs simple mathematical model for Late Cenozoic climatic changes based on hypothesis that forced and free variations of concentration of atmospheric greenhouse gases (notably CO₂), coupled with changes in deep ocean state and ice mass, under additional "pacemaking" influence of earth--orbital forcing, are primary determinants of climatic state over this period. Goal is to illustrate how single model governing very long-term variations and higher-frequency oscillatory variations in Pleistocene can be formulated with relatively few adjustable parameters.
