Global warming is the most pressing challenge facing the world today. After examining what global warming is, I have realized that human activities have a large impact on how the earth’s surface temperature is due to the greenhouse effect. I also have realized the impact that global warming can have on the earth. We as human’s need to do what we can to lower our contributions to the global warming before it is too late. Global warming is the increase of earth’s average surface temperature due to the effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which traps heat that would otherwise escape from earth. This is a type of greenhouse effect. Upon doing my research I discovered that human activities impact global warming. The effect of human activities on the atmosphere mainly is pollution. Livestock farming is one impact. The livestock let off a large amount of methane during their digestion. Greenhouse gases such as carbon dioxide, methane, nitrous oxides, chlorflurocarbons (CFCs) and tropospheric ozone. Human activities are increasing the concentrations of these substances, which in increase the greenhouse effect and it causes global warming. Another activity would be the ozone hole. Chlorfluorocarbons and other human generated chemicals were stopping the formation stratospheric ozone. It protects life on earth’s surface for UV radiation. Some of the other ways that humans have an impact on the atmosphere are deforestation, the logging or cutting down of trees releases carbon and reduces carbon sequestration capabilities of the forests. Burning fossil fuels (coal, oil, and natural gas). These thing’s release carbon dioxide that has been stored underground for hundreds of years. On the subject of impact, I have realized what an impact that global warming can have on the earth. Some of the impacts would be, rising seas, changes in rainfall patterns, increased...
