Quantitative interpretation of atmospheric carbon records during the last glacial / interglacial transition

The cause of the glacial/interglacialchange in atmospheric pCO2 is oneof the most interesting aspect inpaleoclimatic research still unknown.Forcing a coupled ocean-atmosphere-biospherebox model of the global carbon cyclewith proxy data over the last glacialtermination we are able to quantitativelyre...
