Abstract: 
Climate change is one of the modern problems for human beings. It is a disaster for the earth.  The recent climate changes are mostly influenced by increase in amount of CO2 and some greenhouse gases in atmosphere. To consider the climate change, data of meteorological station (synoptic) in Urmia from 1950-2000 has been used. The amount of changes in parameters related to temperature, precipitation and number of sunny hours has been compared through linear regression. The results showed that maximum average temperature within last fifty years has not been uniformly increased (P=0.05). However, minimum average temperature decreased until 1978-83 in each decade during the following months like: March and October (0/6°C), June, April and November (0/4°C), May and August (0.5°C), July (0.3°C), September (0.7°C). There has been (0.5°C) increase annually. The minimum average temperature increased within 1978-83 as the following: June (1.4°C), July (1.1°C), August (1.5°C), September (0.9°C) and December (1.5°C). Therefore, there has been (1.1°C) annual increase. Maximum temperature decreased in each decade as the following: July (0.4°C), August (0.5°C) and October (0.6°C). There has been a decrease of (0.4°C) annually. Average amount of rainfall was not significant during last 50 years. Average numbers of sunny hours in each decade increased as February (1.475 hour), March (1.83 hour) and May (1.54 hour). Consequently, It is said that universal climate change in this region resulted in temperature decrease and did not have any effect on rainfall and numbers of sunny hours.
