Global Warming
Global warming is already taking place. It stopped being a prediction. The temperature at the earth’s surface has averagely increased by around 0.60 C. Both the oceans and the air are warming. It is believed that the greenhouse gases’ concentrations in the atmosphere have increased dramatically since the periods of pre-industrialization. This condition is caused by the activities of human beings most especially through the burning of fossil fuels such as natural gas, oil, and coal (Wang & Chameides 1). Deforestation is also another cause. This essay will discuss what global warming is, its causes and effects.
Global warming is the rise in the mean temperature of the earth’s surface because of the effects of the greenhouse gases. The carbon dioxide emitted from deforestation and the burning of fossil fuels. These activities trap the heat, which is supposed to escape from the earth. Water vapor is the most significant gas, which is emitted by greenhouses. The greenhouse gases’ concentration is lesser than the concentration of other gases like oxygen and nitrogen, which are the most significant gases in the atmosphere. However, both oxygen and nitrogen are not greenhouse gas. None of them has atoms above two in their molecular composition. Therefore, they do not have the modes of internal vibration that are present in gases, which consist of more than two atoms. Carbon dioxide and water have the modes, which absorb and emit infrared radiation, which in turn…
