Qom as one of the provinces with the lowest amount of rainfall in Iran, is facing adverse effects of growing population, developing industrial and agriculture activities along with rainfall reduction, temperature and wind increase and unbridle exploitation of water resources over recent past years. Therefore, it is necessary to analyze the climatic variable factors trend to be considered in managing, planning and proper development of the province. The climate change is the main challenge in area. To that end, Mann-Kendall test has been used to process a few climatic variables from 1989-2014 in the area. This suggests average minimum and average annual temperature have experienced dramatic change and have positive significant variability at 99% reliability, but average annual rainfall shows no significant trend. Average annual relative humidity fluctuates wildly and in 2010, after a sudden change, follows a noticeably upward trend at 95% reliability. Average wind speed has had a rising trend since 2001, but no sudden change occurred until 2013. Almost all noticeable upward trends and sudden climatic changes happened over late four years of research. Intensive rainfalls, water/wind erosion, desertification, and increase in the intensified droughts and decline in water resources as well groundwater level and quality are among adverse effects of climate change.
