Climate change, especially global warming affect s every aspects of the environment, social
structure, and food security. The zagros region due to its rugged nature and diverse climate is
very vulnerable to climate change such as temperature warming and rainfall decrease. In order
to unclose the signs of climate change in the Zagros region, the existing monthly rainfall, rain
days, mean, low and high temperatures of 26 stations in the region were studied. These
stations had data with different durations ranging from 17 to 55 years. The normality of the
time series were tested via lobly force, and their trend with Ljung-Box and Mankendal Tau.
The degree and sign of the trend were tested by correlation coefficient.
The results did not show any significant trend in the rainfall series. But the mean low
temperature and daily temperature range showed significant trend. More than 90 percent of
the stations showed significant increasing trend in the minimum temperature. While the daily
range showed both increasing and decreasing trends.
