| Summary: | The objective of the present work is to simulate the equilibrium climate at 5 different stages of the last deglaciation, in order to assess the respective role of different forcings: insolation, ice boundaries and sea surface temperature. We use as forcing the radiation data from Berger (1), the ice sheet boundaries from Denton (2) and the sea surface temperature from CLIMAP (3). In these experiments we use Adem’s thermodynamic model which is a hemispheric grid model with a realistic distribution of continents and oceans and which includes these three forcings as input data. The procedure used is to simulate first the climate for present conditions and then for the 5 stages of the deglaciation for which Denton gives ice boundaries: 18, 13, 10, 8 and 7 kyr BP.
