摘要: Abstract A series of General Circulation Model experiments are performed to examine the role paleogeography as an explanation Tertiary global cooling trend. Systematic long-term variations in topography and land—sea distribution potential causes climate change. However, model sensitivity indicate a geographically related during last 20 million years, but not Cenozoic Coarse resolution changes geography throughout may be Either events, some related, or another forcing factor, most probably atmospheric CO2 concentration, offered alternative explanations
