Climatic data from four meteorological stations
in Iraq (Mosul, Baghdad, Basra, and Rutba) were obtained.
The recorded temperature data since 1960 till 2007 and
rainfall and evaporation data since 1960 till 2008 and 1970
till 2008, respectively, were used and interpreted. This
study showed an increase in temperature of about 5°C/
47 years and an increase in evaporation rate with a decrease
in the rainfall rate. Carbon dioxide in the atmosphere
appears to be a factor controlling climate change. Basra
climate, due to its location which is nearest to the Arabian
Gulf, is expressed as a coastal climate and has a different
behavior from Mosul, Baghdad, and Rutba, which are
considered as terrestrial climates.
