Global warming is a crucial point for discussions around the whole world. Though not many people pay their attention to climate change, they cannot neglect their dependence on the weather and the natural conditions they have to live under. The world is changing due to the effects of global warming, and people should understand their responsibility for these changes. There are many reasons for global warming, and human activities should not be defined as the only harmful aspect. There are many natural events, which cannot be controlled by humans, including the increase of gas movements in the atmosphere. Besides, a certain attention should be paid to the changes of the Arctic climate in the forms of temperature increase by 3-5 °C, the melting ice sheet in such places as Greenland, and significant changes in the ocean circulations (Taulavuori, 2013). Therefore, it is not enough to blame people for causing the alleged warming. It is important to comprehend the pros and cons of global warming and investigate different aspects of this complicated natural challenge. In this paper, a certain attention to such events as gas movements, temperature changes, and the raises of the oceans’ levels due to numerous human activities and the intentions to facilitate their lives by means of technologies will be discussed to support the presence of global warming in the modern world alongside with the fact that global warming is a natural event that cannot be avoided or predicted for sure because of the presence of natural storages of gases like in oceans or plants that does not support the idea of global warming because of human impact. Pros to Support Global Warming as a Negative Outcome of Human Activities Nowadays, people pay much attention to the discussions of global warming and the impact of humans on the development of this event. Up-to-date sources and recent investigations help to comprehend how crucial the correct direction of human activities could be. Still, people have to realize that the majority of their decisions and the intentions to improve their lives lead to significant changes in the environment. There is a number of pros of global warming that could be used to support the idea that human activities have a certain impact on the quality of life and the changes that have occurred recently. These points include the movement of gases in the atmosphere as a result of certain human activities, the increase of the temperature because of greenhouse gas emissions, and the rise of the oceans’ level that is caused by warmer temperatures in the atmosphere. Greenhouse Gas Effects on the Environment Figure 1. CO2 Cycle (Drake, 2014) The movement of gases that occurs between the atmosphere and the sea is a well-known fact that cannot be ignored (Drake, 2014). There are three dominating gases in the atmosphere, which are carbon dioxide (CO 2 ), oxygen (O 2 ), and nitrogen (N 2 ). The presence of CO 2 is considerable and could be explained by the necessity to burn fossil fuels or the inability to control forest fires. The movement of this gas is explained in Figure 1 that proves its transformations in different parts of the same climate system (Drake, 2014). There are many investigations w
