Global Warming Casestudy

Extracts from this document...


[5] Introduction I am doing a case study on the topic "Should we be worried about Global Warming." In this case study, I will include scientific information, arguments for and against the above statement, a conclusion and a bibliography, which will state where I got my information from. The Science What is Global Warming? Basically, global warming is the increase in the average temperature of the Earth's surface [1]. If global warming is happening, the ice caps should be melting and the sea-level will begin to rise [4], flooding parts of many countries, damaging homes, habitats and crops. What causes Global Warming? A diagram showing how the greenhouse effect works Scientists have concluded that human activities are contributing to global warming by adding large amounts of heat trapping gases to the atmosphere. Our fossil fuel use is the main source of these gases. Every time we drive a car, use electricity from coal-fired power plants, or heat our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the air.[6] Fossil Fuels are coal, oil and natural gas. ...read more.


This graph shows the depletion of the global ozone layer. It proves the ozone layer is becoming thinner. [8] Arguments for We should be worried about global warming. This is the view of some people. There is evidence that average global temperatures are on the increase. The graph (right) shows the increase of temperatures from 1860 to 2000. General global warming is expected to lead to an increase in the number of extremely hot days and decrease in the number of extremely cold days. Warmer temperatures will lead to more severe droughts and floods in some places, and because rapid climate changes are unpredictable, it may lead to a few weather 'surprises'. Even if humans adapt to the weather conditions, many animals and crops will not and this will prove to be a massive problem for generations.[2] Also sea-levels will rise, as the polar ice caps melt, meaning animals such as polar bears on the North Pole will become extinct and parts of the world will flood. ...read more.


When I look at the sources on either side of the ongoing dispute, I think I find the "arguments for" more credible. I decided to evaluate all the sources on 5 criterions, and I decided that the source must meet at least 3 of these criterions. The criterions were:- * Is the source biased? * Does the source carry a good reputation? * Have they written other stories on this topic? * Does the source have much relevance to the topic? * How significant is the source After using these criterions, I decided all my sources were reliable, except the UCSUSA website as this only matched 2 of the credibility criterion, whilst the other sources matched at least 3, whilst Wikipedia and BBC News matched all 5 criterions. Some people still think Global Warming is a massive problem in the world, whilst others think it is a money-making scam. I believe we should be worried about global warming because of what could happen, such as high temperatures and flooding land. The defining sources for me were BBC News, Wikipedia and www.personal.dundee.ac.uk as they had key information to my case study. ...read more.

  1. Is Global warming Natural or Man-made?

    There has been a variation of temperature over millions of year's history. His solution was to reduce human effects through emissions. He also said to not spend the national budget trying to stop or reverse the natural process. On both sides of the argument, the data is misintertpresnted or misused.

    These are some of the things people dump in the water cardboard that takes 2 weeks to degrade. Newspaper takes 6 weeks to degrade. Camera packaging takes 6 weeks to degrade. Foam takes 50 years to degrade. Aluminium takes 200 years to degrade. Plastic packaging takes 400 years to degrade.

  2. My case study is about global warming and why it happens.

    and stratosphere (the upper layer of the atmosphere) the ash clouds goes around the earth and the sun light is block by the ash particles so there is less light reaches to the surface. The temperature decreases. "Large eruption columns inject ash particles and sulfur-rich gases into the troposphere and stratosphere and these clouds can circle the globe within weeks of the volcanic activity.

  1. Are humans to blame for Global warming or is it a natural phenomenon? ...

    (Diagram above) this warms up the planet. Some greenhouse gases are man-made such as chlorofluorocarbons (CFC's) which is the most well-known. However, not all of them are man-made; some greenhouse gases exist naturally such as: carbon dioxide, water vapour, methane gas, ozone and nitrous oxide.

  2. Is human activity responsible for increased global warming?

    Lastly, another reason why people may say that human activity is the number reason for increasing global warming is based on this graph: We can see clearly the trend that is shown on the graph: the fluctuation of carbon dioxide in the Earth's atmosphere has changed over the past 160,000 years.

  1. Give a brief explanation of how increasing levels of combustion of fossil fuels is ...

    Climate change may be beneficial to some regions, though in other regions it may be devastating. Growing season will be affected and use of land altered, that's if land remains above sea levels, as it is forecast sea levels will rise as a result of global warming as ice caps at the polar regions will melt.

  2. Are Humans causing global warming?

    could afford them, so because of the cars producing carbon dioxide, the levels of carbon dioxide would rise. Another cause of the sudden increase of the carbon dioxide levels could well of been due to the use of industrial machinery, this would have been because of the manufacturers would have
