Global warming is increasing which will cause climate change. During the last century, average earth temperature has been increased about 0.74 °C Centigrade. Scientists have predicted that within next 100 years, average earth temperature will increase about 1.5 to 3.5 °C Centigrade. This amount of increasing in temperature can change the earth climate and causes unforeseeable climate status and deranges most of humanʹs equations. According to this study, global warming causes changing the pattern of precipitation, melts the polar ice; changes the level of oceans water, decreases the level of lakes water and amount of drinking water. It also causes more tropical storms, increases the outbreak of diseases which are related to temperature, decreases food production, and increases the rate of death in less developed countries, mortality of plants and animals which can not adapt to new conditions and changes in agriculture because of the climate change and overthrow of alive beings because of annihilation of natural habitats. Results of this phenomenon in Iran are including: Gonu tropical storms, increasing water consumption in agriculture, increasing the level of water in Persian Golf and threatening the human health. In this paper we try to investigate the reasons of earthʹs temperature rising and its effects and results by using documentary method and at the end we will give some suggetions in order to control the trend of earthʹs temperature rising.
