Climate change means any significant long-term change in the weathering rate (which can include temperature, wind conditions and rainfall) that occurs in a particular area. Changes can occur due to the dynamic processes of the Earth, external forces and human activities. A study was carried out to identify trends in mean temperature (maximum and minimum), air temperature, and relative humidity time series of weather station covering a period of 50 years in Najaf city south-west of Iraq. To determine a strong relationship between two variables between years and months of mean temperature (maximum and minimum), air temperature, and relative humidity forecasting the parameters, which were statistically measured by Pearson’s Correlation coefficients(r) using SPSS program. Also, the variables are plotted. Variables and Regression equations were considered for analysis 12 a month basis. The results show that mean minimum temperature have increased month to month, but month July the trend increased more than before up to the maximum value (0.04). While relative humidity trends have decreased by a value except for November.
