Anatolia is characterized by strong regional contrasts. Numerous sedimentary archives allow the reconstruction of its Quaternary environmental history. Formerly more extensive mountain glaciation is testimony to past changes in snow-line, although the glacial chronology remains to be established. In this review, we focus on two main palaeoclimatic archives ; firstly, pollen-based evidence of palaeo-vegetation, and secondly, fluctuations in the water level and salinity of closed lake basins. At around the LGM, Anatolia experienced a substantial expansion of cold steppe vegetation at the expense of forest and woodland. Coinciding with this, closed lakes were far more extensive than at present, a combination best explained by a reduction in evaporation and evapotranspiration losses, accompanied by higher catchment runoff coefficients. Several large lakes appear to have undergone a major water level regression prior to the onset of warming, suggesting an intensification of climatic aridity, although lake levels rose once more during the Late-Glacial period. The impact of warming towards the end of the Pleistocene had a regionally-differented effect on vegetation. In South-West and North Turkey, forest re-advance was interrupted by a period of inferred colder, drier climate which may correspond to the Younger Dryas chronozone. In central and East Turkey, forests and woodland only began to return during the early Holocene, and maximum tree cover was not achieved until ca. 6,000 BP (conv. BP). While there exists evidence for Holocene climatic variations, they are as yet poorly defined and understood. The major changes in climate which occurred from the Pleniglacial to the early Holocene radically changed the environmental resource base available to prehistoric societies, and seem certain to have had an important effect on human adaptations
