Carbon dioxide is the main greenhouse gas emitted by humans, with the United States being the leading producer in the world. If global warming continues, there will be many effects on Earth that could be devastating. Weather will become more extreme, and the arctic sea ice will melt, causing a barrage of other serious effects. While global warming implies the entire globe will warm, some places may, in fact, cool.
The Problem of Global Warming "The climate of the Earth is changing" (Melillo 1999:183). These words sum up exactly what is happening to the environment today; it is changing. Yet, what has brought on this change? There are many factors that contribute to climate change, however, the most important one that has become a very relevant issue to humans today is global warming. Global warming is the increase in the Earth's average surface temperature from an increase of greenhouse gases (primarily Carbon Dioxide) in the atmosphere.
CO2 levels would naturally rise as the Earth warms up. However, over the past 200 years, humans have contributed to CO2 levels rising dramatically, way above even the highest historical levels, and this has hastened global warming. Lutgens and Tarbuck (2014) explain that the Earth’s atmosphere greatly influences its surface temperature and its life-giving environment. The major components of the atmosphere are nitrogen and oxygen, composing about 99% of the atmosphere. The next major component is carbon dioxide (CO2).
The rate at which the earth is warming is what is so alarming, since it can have such a profound negative impact on the ecosystem. Simon et al., (2007) note that prior to the industrial revolution the concentration of CO2 levels in the earth’s atmosphere was roughly 280 parts per million (ppm), however today’s levels are at 385 ppm and still climbing. The earth’s oceans are always in a constant exchange of carbon d... ... middle of paper ... ...ited American Geophysical Union. (2007). AGU Position Statement: Human Impacts on Climate.
In many developing countries, the main cause of death is diarrhea contracted by drinking water. Human and animal wastes are not the only water pollutants. Sometimes pollutants can come from an oil spill or another single source. When this occurs, it is called point source pollution. (“ Categories of Pollution: Point Source”, 2008) The global picture of water and health has a strong local dimension with some 1.1 billion people still lacking access to improved drinking water sources and some 2.4 billion to adequate sanitation.
Climatology is described as the study of the origins and impacts of climate. To understand climatology, one must know the true definition of climate. Climate, simply, is the typical weather of a specific geographical region on earth. Climate can be affected by many factors. Some of these factors consist of: pollution, outgassing of volcanoes, seasonal changes, natural disasters, and carbon dioxide emissions, and greenhouse gasses.
“Climate change refers to any significant change in the measures of climate lasting for an extended period of time. In other words, climate change includes major changes in temperature, precipitation, or wind
Cholera The disease, cholera, is an infection of the intestines, caused by the bacterium Vibrio cholerae. As stated in Microbes and Infections of the Gut, the bacterium is “a Gram-negative, comma- shaped, highly motile organism with a single terminal flagellum” (105). Cholera is characterized by the most significant symptom that presents with the disease, diarrhea, and victims can lose up to twenty liters of body fluids in a day. Cholera can be a serious disease, due to the serious dehydration that can occur, but it is only fatal if treatment is not administered as soon as possible. This research paper includes information on the causes of cholera, symptoms, ways of treatment, studies of treatments, complications that may occur, the tests and diagnosis for cholera, and finally, the ways the cholera bacterium may be transmitted.
Greenhouse gas is a type of gas in atmosphere which absorb and emit radiation.Certain gases will block by atmosphere when escaping from the Earth and keeping the Earth warm.Therefore,this process is called Greenhouse Effect .The primary gases in the Earth are water vapour , carbon dioxide , methane , nitrous oxide and chlorofluorocarbons etc.However,human activities are changing the natural greenhouse.According to the IPCC Fourth Assessment Report issued on 2 February 2007 , it can be observed that there was a significant increase in globally averaged temperatures since the mid-20th century .One of the reason is the industrial revolution ,the develop... ... middle of paper ... ...rgy.If we save water,it potentially reduce the greenhouse gas emission. In this essay i have discussed the reason of why human activity is the main cause of climate change rather than natural cause ,the effect of climate change and presented the possible solutions.Besides,the main cause of climate change is human activities such as a large amount of greenhouse gas emission and over-logging.These activities expand the greenhouse effect and rise the global temperature.Moreover,climate change affect the sea level,the amount of extreme weather event and the acidification of ocean.To solve these problem,international cooperation is the most important solution and people can also reduce the greenhouse gas by saving energy.Overall,I think the problem of climate change will be improved in the future since more and more people have rose their awareness of environment issues.

Climate Change is the significant change in the climate and distribution of weather patterns on Earth ranging from the last decade to millennia earlier.
