الملخص

The research aims to study climate change in some climatic elements according represented by climatic cycles (b degrees heat Minor and the vast amount of rain) stations (Mosul, Kirkuk, Khanaqin, Baghdad, Diwaniyah, Nasiriyah, Amara and Basra) for the period (1946-2011) and its impact on some field crops in the area of Iraq, namely, (wheat, barley, rice, maize, cotton and sesame) and fifteen province is (Nineveh, Salahuddin, Diyala, Kirkuk, Anbar, Baghdad, Babil, Karbala, Najaf, Qadisiyah, Wasit, Muthanna, Dhi Qar, Maysan and Basra), as was extracted rate of change of the area of each crop of the studied crops rate, it became clear through research that my degree heat heading towards change positive for the majority of climatic cycles and months of the plants studied in Iraq and the direction the negative of the amount of change in the amount of rainfall for most of the studied stations. The reflected the change in the climatic elements above in the area of field crops studied tended change as field crops area ratio, negative change for most of the studied provinces.
