GCM analysis of local influences on ice core delta signals
International audience A high resolution GCM is used to examine the effect of changes in local surface climate parameters on the ice sheets that can influence the interpretation of the isotopic signal of the ice from deep cores. The model suggests that the 10øC difference between the LGM surface tem...
