Evaluation climate change in Iraq using the general circulation model

الملخص EN

Global Climate Models (GCM) has been developed to perform climate projection to simulate and understand climate change in response to emission of greenhouse.

The aim of this study is to use simple numerical climate models to investigate effect of various parameters, functions, and components of climate system on the temperature rise.

Two climate changes scenarios used to estimate and explore the future rise surface air temperature over Iraq until 2050.

EZgcm project has been supported at times by National Aeronautics and Space Administration (NASA), as an easy model has been used by research to study climate of the past, present, and future.

The results have been shown that the surface air temperature of Baghdad city was at starter of the first decade of the study for scenario A (16.8°Q with an increase of about half a degree in each decade until reaching 21.2 •C in the last decade of the study and this is the highest score recorded in the study for scenario A The temperature of scenario C has been 17.8 ° C at the first of the study, which is higher than the scenario A.

However the temperatures slow rise over last time pored study as the temperature increases a little to reach 18.38 C in the last decade of the study.
