The evidence of paleoclimates of late Paleolithic period indicates that during this period climate fluctuated. Little evidence currently exists about the climate conditions 55 to 40 Thousand years ago ( henceforth kya) when the transition between the middle and upper Paleolithic period occurred. Although the upper Paleolithic climate was probably wetter than the present, it is still drier than Early and main Wurm. The climate of Upper Paleolithic in the Levant*corresponds to the late part of oxygen stage 3 which was fairly dry between 45-32 kya. The arid climate occurred between 23-22 kya in the Levantine upper Paleolithic. It seems to correspond to the early part of oxygen stage 2. The climate of Upper Paleolithic period between 32-22 kya was drier than the period between 45-32 kya and even the present. The last climate fluctuation of upper Paleolithic began around 24-22 kya and ended around 14-13kya. It is the last stage of the Levantine upper Paleolithic period which was the drier and colder than early and middle Paleolithic period .
