The change in the rates of maximum temperatures and precipitation and their impact on the change in the discharges of the Tigris River in Iraq

Abstract

Climate change is one of the most important problems facing man and his environment in all its elements since ancient times, and today this problem has become one of the most serious challenges that concern scientists, especially geographers, as this phenomenon accompanies human civilized activities after it was previously a natural product embodied in the comprehensive changes that the earth witnessed through its ages. The study of climatic changes with their effects has also become vital and essential, especially with the emergence of their clear effects on water resources in a number of countries in the world as well as in the study area. Studies indicate that since the forties of the last century a new trend has begun in global climate studies.
