Evaluation the Effects of Climate Change on Iran's Environment

According to the result of research on the effects of climate change, the most important challenge of climate change in the world is rising temperatures due to rising greenhouse gases. Rising temperatures have changed the pattern of rainfall throughout the planet on terms of type, spatial and temporal distribution. This process has the most negative impact on reducing freshwater resources. According to global models of climate change, Iran is one of countries that will face severe water shortages in the coming decades due to rising temperatures, declining rainfall, declining frosty days, and increasing hot days. In Iran, in addition to rising temperatures, unbalanced population growth and increasing water consumption, will intensify the reduction of freshwater resources and increase dust. Also, agricultural and livestock activities in Iran are strongly dependent on climatic conditions, especially rainfall and temperature changes, especially since more than 50% of Iran’s agricultural lands are cultivated in the dry season. For this reason, climate change will have severe negative and decisive effects not only on living conditions, the environment, drinking water supply, but also on the country’s food security. In the present study, with the aim of determining the outlook for future climatic conditions in Iran, research conducted in the field of statistical exponential microscale output of ocean atmosphere circulation models to evaluation rainfall and temperature parameters under different emission scenarios was collected. With the method of descriptive content analysis and scale of results, a comprehensive view of the climate, its risks and especially climate change in Iran should be presented.
