The objective of current study is to investigate the temperature variability caused by emission of greenhouse gas (GHG) and changes in precipitation in Bamyan center at 34.75 degrees north latitude and 67.75 degrees eastern longitude. To this end, maximum, minimum, and range of annual temperature were obtained from National Oceanic and Atmospheric Administration (NOAA) for the period of 1987- 2016. The statistical-graphical Technics and liner regression was used to analysis the data. Our findings showed that during the recent three decades there were noticeable changes in maximum, minimum, and range of annual temperature by 0.71, 0.34, and 0.36 degree Celsius, respectively. The annual mean, maximum and minimum precipitation of under investigation region are 256, 559 (in year 1991), and 90.9 (in year 2011) mm, respectively. During the under study period the precipitation decreased by 6.9 mm
