The causes of the growth and collapse of the large Pleistocene ice sheets is a topic intense scientific debate. The amount of new data and ideas has been prodigious the last ten years. This review concentrates on the shifting patterns of glacial and shrinkage during the last Glaciation. We also examine reconstructions conditions during the maximum of this Glaciation about 18,000 BP, and mechanisms that might have caused the rapid collapse of many of the world's sheets between 18,000 and 8000 BP. Our paper focuses on the North Atlantic because it is there that the major Pleistocene ice sheets grew, developed, retreated.
