Global Warming Essay

This essay is based on Global warming and the cause and effect of it. â€Å"Global warming I define as an increase in the earth’s atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution. Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution† (Merriam-Webster, 2013). In â€Å"2007 the UN Intergovernmental Panel on Climate Change forecasted that by 2100 global average surface temperatures would increase 3. 2–7. 2  °F (1. 8–4.  °C), depending on a range of scenarios for greenhouse gas emissions, and stated that it was now 90 percent certain that most of the warming observed over the previous half century could be attributed to greenhouse gas emissions produced by human activities (i. e. , industrial processes and transportation). Many scientists predict that such an increase in temperature would cause polar ice caps and mountain glaciers to melt rapidly, significantly raising the levels of coastal waters, and would produce new patterns and extremes of drought and rainfall, seriously disrupting food production in certain regions† (Wojtal-frankiewicz, 2012). Other scientists maintain that such predictions are overstated. The 1992 Earth Summit and the 1997 Kyoto Protocol to the United Nations Framework Convention on Climate Change attempted to address the issue of global warming, but in both cases the efforts were hindered by conflicting national economic agendas and disputes between developed and developing nations over the cost and consequences of reducing emissions of greenhouse gases† (Kitson, 2011). To begin, the evidence to this article in Wikipedia that show the originality s the use of departmental organization that show the cause of global warming. This organization is known as (UNFCCC), they highlighted some Global warming controversy. It also showed a pie chart which indicate that glaciers have been retreating since the early 1800s. In the 1950s measurements began that allow the monitoring of glacial mass balance, reported to the World Glacier Monitoring Service (WGMS) and the National Snow and Ice Data Center (NSIDC). Moreover the bibliography was also stated to show where the inform ation was came from. Where some of it was from official people with a higher state of position. Information on this article was also picked from books and journals and a full bibliography was provided for it. Looking at this, it can be said that the information was neutral and not a made up one. In addition, the article also has detailed factual information that was the use of another pie chart that indicates the â€Å"Contribution of natural factors and human activities to radiative forcing of climate change. Radiative forcing values are for the year 2005, relative to the pre-industrial era (1750). The contribution of solar irradiance to radiative forcing is 5% the value of the combined radiative forcing due to increases in the atmospheric concentrations of carbon dioxide, methane and nitrous oxide†. This stratices was formed in a project known as IPCC. The article seems to be neutral and unbiased due to the use of quotation and picture with a full proper bibliography. The article is similar to our text book as it has the similar format of writing. These are the use of table of content, title, subheading and bibliography. Thus, the information that was in the article was relevant to the topic that I chose. Moreover, some of the addition information that was it the article was the use of the diagrams to show the greenhouse effect. It shows Greenhouse effect schematic showing energy flows between space, the atmosphere, and earth’s surface. Energy exchanges are expressed in watts per square meter. The article also has used the different language that is for better understand to those who does not know much in English. Thus, the article could have used pie chart and line graph to show the increase in the sea level due to global warming. It also should have discussed a country that is mostly affected due to global warming. Final, Wikipedia is not a favourable web site due to some of its features that allow anyone to edit it anytime. The most dangerous feature is the edit button in it. Thus, the overall article was well structured with having least error in it. It was also simple and straight forward to make it user friendly. This was the use of table, pictures and number to add simplicity to the article. The article has some complex situations where it uses different language. So that people can read the article in their own language.
