Abstract: Climate change became an important filed of research. It is believed that climate change may be one of the greatest threats facing the Earth’s ecosystem. Recent years show increasing temperatures in various regions and/or increasing extremities in weather patterns. This research explore the trends in various weather elements over the Hillah city in central Iraq using Merra-2 data for 37 years (1980-2016). The results indicated that the most affected elements by climate change were the temperature and precipitation. Temperature trend is increasing while precipitation is slightly decreasing over the 37 years period. Other weather elements such as atmospheric pressure, relative humidity and wind showed no distinct trends and their patterns are those of arid and semi-arid regions. Low-pressure patterns and dry conditions during Summer and high-pressure patterns and wet Winter. The wind during Summer is higher than its values during Winter. The wind direction is mostly Northwesterly.
