Abstract: When infrared radiation from the earth is emitted and back to it, the gases known as greenhouse gases can absorb this entire thermal energy, which is what causes global warming. In addition to other gases including those present on the surface of the ozone layer, nitrous oxides, and fluorinated gases, water vapour is one of the most significant greenhouse gases, albeit its impact is less. Although it is a straightforward type of atmospheric gas, greenhouse gases have a huge impact on the planet’s energy system and have been implicated in significant global climate change. The methods used in the study depend on the daily and monthly average CH4, H2O, N2O, CO2 and temperature (T) and Dewpoint temperature (Td) and relative humidity (RH) taken from the European Mediterranean Weather Forecast (ECMWF) during the year (2021) for the Baghdad region. As a result, in the Statistical analysis of air pollutants, carbon dioxide gas represents the highest correlation with heat, and this leads to high global warming, followed by ozone, methane, and water vapour.
