In contrast with the last few millennia that are characterized by a rather stable climate, the period between 21000 and 6000 years before present experienced a complete reorganization of all climate compartments, e.g. atmosphere, ice sheets and ocean, lakes and rivers. It is only recently that paleotemperature records covering the last deglaciation have become available at a global scale, including tropical sites that are very remote from the main center of variation linked to the melting of former ice-sheets on each side of the North-Atlantic basin. In addition, the dating of these records is now sufficiently accurate and precise to allow meaningful compilation and comparisons with model simulations performed in a transient mode.
