Atmospheric chemistry plays an important role in the global climate system as greenhouse gases (GHGs) are involved in the Earth\'s climate system, radiation, and atmosphere. GHGs such as carbon dioxide (CO?), methane (CH?), nitrous oxide (N?O), and halogenated compounds absorb infrared light and emit it in the atmosphere of Earth as greenhouse gases, and this is associated with the greenhouse effect. The heat in the lower atmosphere is retained, and global warming and the surface temperature of the Earth are increasing. As such, the chemistry of greenhouse gases depends on the concentration of atmospheric gases as well as their chemical composition, reactivity, lifetime, and interaction with solar and terrestrial radiation (e.g., photochemical reactions, oxidation processes, gas-aerosol interaction). For example, methane oxidation and nitrogen oxide cycles play an important role in ozone production and secondary radiative forcing, so that the chemistry of atmospheric chemistry and climate are interrelated. Since the 20th century, anthropogenic activities such as combustion of fossil fuels, industrial pollution, deforestation, and agricultural processes have increased the GHG levels in our atmosphere, thus adding to the natural greenhouse effect. However, CO? is the most important greenhouse gas present now, but it is not the only one that is responsible for warming, and other gases such as CH? and N?O are essential in the global warming process as well. Atmospheric chemistry reveals that the greenhouse effect is not only dependent on CO?, but many interacting gases are involved in the climate processes. Recent studies have also shown that changes in the composition of the atmosphere can lead to severe weather events, radiative forcing, and climate feedback loops, and the consequences can be dramatic for global warming. In any system for climate change, the interplay of greenhouse gases, aerosols, and chemical reactions in the atmosphere should be taken into account. From a global perspective, understanding the chemistry and nature of greenhouse gases is necessary to understand what is driving us toward global warming. The chemical properties and interactions of these gases are also useful in understanding how climate change must be countered in the long run and how to identify solutions to this problem for climate policy.
