Greenhouse gases formation and emission

The rising temperature of earth, known as global warming, is partially the result of the rise of greenhouse gases concentration in the atmosphere since the beginning of the 20th century, mostly due to anthropogenic activities. Global warming is one of the major threats to the environment because of the resulting climate change. This article gives an overview of the formation of most important greenhouse gases which are released to the atmosphere. The greenhouse gases described in this article are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and ozone (O3). Particular attention has been paid to the soil conditions under which greenhouse gases are formed.
