A Catastrophe Model of the Paleoglimate
Abstract A simple qualitative model of global ice cover is presented to account for the apparent catastrophic transitions between glacial and interglacial climates. Unlike the Budyko (1972) and Weertman (1976) models, the catastrophe model employs a second control parameter besides the oribtally ind...

Summary: | Abstract A simple qualitative model of global ice cover is presented to account for the apparent catastrophic transitions between glacial and interglacial climates. Unlike the Budyko (1972) and Weertman (1976) models, the catastrophe model employs a second control parameter besides the oribtally induced insolation fluctuations to differentiate between fast and slow glaciological response mechanisms. It is conjectured that this second control parameter is linked to isostatic actions occurring beneath the continental crust which shift the dynamic emphasis from terrestrial to marine ice margins. |
