Iraq is one of the countries in the Middle East most facing the impact of climatic changes, the most important of which are high average temperatures, decreasing amounts of precipitation, drought, and desertification. Methane (CH4) is a greenhouse gas emitted by human activities and has a direct impact on the climate, absorbing part of the heat into the atmosphere and preventing its leakage into space, which leads to an increase in air temperature. This phenomenon is known as global warming. Carbon dioxide (CO2) is one of the greenhouse gases, which is constantly released into the atmosphere from natural sources, is transparent to the light rays coming from the sun where it does not absorb in the field of ultraviolet radiation, but absorbs infrared from the earth, thus is considered one of the greenhouse gases and forms around 60% of greenhouse gases. The research aims to study the chemical behavior of the effect of greenhouse gases on climate change in Iraq. Data were taken from satellites recorded by the European Center for Medium-Range Weather Forecasts. Copernicus Atmosphere Monitoring Service (CAMS) ECMWF reanalysis for the global climate and weather. This study was selected for the different regions of Iraq (Northern, Central, Western, Southern), during the period (2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017). The scientific benefit of the study lies in knowing the behavior of emissions of chemical pollutants and greenhouse gases and the extent of their impact on the atmosphere after it has become a problem of interest in its effects on ecosystems and human activities. The results showed an increase in the level of methane concentration in August, during which the maximum level of methane concentration was recorded with an increase of (1845 ppb) in the southern region, while the minimum for March was recorded at (1793 ppb) in the northern region. The results also indicated the level of carbon dioxide emission, during which the limit was recorded. The maximum increase was (397 ppm) for May in the southern region, while the minimum was recorded at a concentration level of (391.2 ppm) in the northern region. To address the problem of pollutant emissions and greenhouse gases, the techniques, behaviors, and policies that fall upon each individual must be followed, in addition to using the carbon footprint as an indicator that means determining the amount of greenhouse gas emissions, the most important of which is carbon dioxide resulting from burning fossil fuels, which reflects the extent of the individual's consumption of energy in various activities.
