What are the potential effects of global warming in terms of climate change and how they can be arrested?

Global warming is a worldwide problem and it seems to be worsening year after year. The Earth’s temperature continues to rise making the climate becomes more erratic, forcing many species into extinction and making life harder. The ten hottest years on record have occurred in the last 14 years and the hottest of all was 2005. (Al Gore 2006). Some people do not want to admit that this problem is serious. It is true that the temperature is rising but the average temperature is quite stable over some periods of time. (Holli Riebeek 2007). However, they did not notice that these small changes in temperature will correspond to an enormous change in environment. Thus, we have to work fast to overcome the potential effects of global warming by finding a way to arrest it.

The most potential effects that we can draw out are the loss of low-lying ground corresponds to the melting of sea ice at the North Pole and South Pole. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. (Holli Riebeek 2007). When they melt, they will release a large amount of water to the sea causing an arising of water levels. People who live near to the sea level, such as in Florida might have the chance to lose their homes and even worse their lives. Not only that, the surface of the Earth also changes where some of the grounds are now gone, wipe out by the sea. Al Gore in a documentary entitled “An Inconvenient Truth” which was release on 2006, said that “A friend of mine said in 1978, if you see the breakup of ice shelves along the Antarctica Peninsular, watch out because that should be seen as an alarm bell for global warming”. The breakup of ice has changed the shape of the Antarctica making it smaller and smaller in size. Other places like Greenland also affected. Tony Blair’s scientific advisor has said that the cause of what’s happening in Greenland right now, the maps of the world would have to be redrawn. (Al Gore 2006). Therefore, we have to find a solution before the land is engulfing with water.

Other serious potential effects are the extinction of plants and animals. Overall, species loss is now occurring at a rate 1000 times greater than the natural background. (Al Gore 2006). The poles may become too warm for creatures that live there. This causes the plants and animals may not be able to adapt to their new surroundings. Some will ended up dead and worst extinct. Moreover, a tremendous increase in heat wave has shown a great impact where many people had died because of it. When the ocean gets warmer, it causes a stronger storm. As the water temperature increases, wind’s velocity increases and moisture content of the storm also increases. (Al Gore 2006). Hurricanes such as Katrina were formed and cause many people to suffer. If we cannot find a solution to this problem, sooner or later more deaths will resulted to extinction, not only to the animals and plants but also humans.

To overcome such problem, people’s attitudes have to change first. It is important that they be more conscious in reducing the percentage of carbon dioxide in the atmosphere. Use less energy for heating or cooling the house as the use of air conditioner releases greenhouse gases. Other than that, less use of cars or any type of vehicle means fewer emissions and it saves fuels. In addition, try to explore your community mass transit system, and check out any options for carpooling. If things continue as they are, we'll soon be using nearly twice of the energy and getting even more of it from fossil fuels. (Chris Woodford 2006). Forest reserve is also important where it produces more and more oxygen so that the balance of the Earth will be stored. Thus, if we manage to work out this problem, the percentage of carbon dioxide could be reduce and in contrast reduces the Earth temperature.

In a nut shell, it is very likely that rising temperatures will lead to more frequent heat waves in the future, and virtually certain that the seas will rise, which could leave low-lying country awash in seawater. Moreover, the amount of carbon dioxide in the atmosphere will continue to increase and Earth will continue to heat up. In other words, global warming will become worse. Warmer temperatures will alter weather patterns that can cause more droughts, rain and even natural disasters like hurricanes. Without drastic action, global warming cannot be resolve. Therefore, it is important that we take good care of our world, the place where we live so that the next generation will not suffer from what we did before. Thus, let us work together for a better future.

1. Title: how can they be arrested
2. it is better to provide a definition for global warming in the introduction.
3. citation- please write the surname and the year (check SACE 2010 harvard guide given in class blog)
4. Topic sentences: write 'one of the effects' instead of 'effects' because you are focusing on 1 effect in each paragraph.

please do the changes and get a print-out as a word document to put in the file.
