The aim of this study is to investigate the trend of spatial and temporal changes in the future extreme temperature of Iran. The data used include daily data of minimum temperature and maximum temperature of CCSM4 model during the basic period of 1986-2005 and the future period of 2006-2050 under scenarios of 4.5 and 8.5 in Iran. The results of studying the trend of warm and cold extreme during the basic period showed that in general, warm extreme has a positive and increasing trend and cold extremes has a negative and decreasing trend in Iran. The results of investigate the trend of future extreme temperature in Iran during the two periods of 2006-2025 and 1428-1404 showed that in the first period and based on scenario 4.5, the trend of cold and warm indicators in most parts of iran have the same conditions as the base period. In the second period, these conditions can be seen with limited changes in the spatial distribution of decreasing trends as in the first period. These results indicate an increase in temperature changes and consequently an increase in extreme events, especially extreme events in different parts of Iran.
