摘要：Climate Change which results from globalwarming is affecting the Tigris and Euphrates River basins in similar ways toall other parts of the Middle East and the East Mediterranean region. Thiscontains also what is historically known as the “Fertile Crescent”, which isthreatened in the same way as the other parts and may disappear altogether. Theclimate change is manifested in increased temperatures, reduced precipitationin addition to erratic weather patterns and decreased annual stream flow of thetwo rivers. These phenomena have been markedly noticed during the last decadesof the last century. Studies show that these changes are linked also to thevariations of North Atlantic Pressure Oscillation (NAO) induced by GlobalClimate Change. Modeling studies on the future trends, in trying to define themagnitude of the changes to be anticipated, reveal clearly that these negativeimpacts are continuous in the future. But, the widely ranging projections andinterpretations of different sources depict an uncertain future for the basin’sclimatic conditions and indicate the need for further modeling studies to reachmore definitive conclusions. These studies show however, a drastic decline ofthe Euphrates and Tigris water resources at the end of this century bysomething like (30 to 70) %; as compared to their resources in the last threedecades of the previous century. The wide variations in the projectionsemphasize the need of further future work on this matter. All in all, thesestudies should bring alarm to all responsible governments in the region toresort to long range planning by adopting rational policies in soils and waterresources management to mitigate the adverse impacts that could hit humansocieties in these events.Keywords: Climate Change, global warming,Fertile Crescent, North Atlantic Oscillation, Euphrates River, Tigris River.
