As far as Iran is located in arid and semi-arid area, the average annual amount of rainfall is lower than its global average. Climate change has made this condition worse through changes in for example magnitude, temporal and spatial distribution of rainfall. Heavier and more frequent droughts and floods are being experienced. Overall, in point of my view three biggest concerns in Iran about climate change are as follows:
1- Floods and droughts
2- Increasing frequency of extreme weather events
3- Water resources scarcity
