Text production draft #2

For decades, cars and factories have spewed billions of tons of greenhouse gases into the atmosphere, and these gases caused temperature to rise between 0.6°C and 0.9°C over the past centuries. Development to satisfy the demands of consumers is triggering global warming. Global warming basically refer to the rising in average temperature of Earth caused by greenhouse gasses especially carbon dioxide. The rate of warming in the last 50 years was double the rate observed over the last 100 years. Once planet starts to warm up, it's very hard to slow down the process—and almost impossible to stop it completely. Global warming means Big Trouble. Ironically, global warming which is caused by an anthropogenic process will cause a slew of inevitable effect and thus, practical solutions and strategies must be prepared to solve this long-lasting global issue.

One of the inevitable potential effects of global warming in terms of climate change is the rise of sea level. Global warming caused an increase in world’s temperature of approximately 2-5 degree centigrade. According to Al gore, the melting of land-base ice in both poles contributes to the rising of sea level. If all the ice melts completely, low-lying nations and islands such as Bangladesh, Beijing, Shanghai, Netherlands, Greenland, Florida, Calcutta, Manhattan and California will be at the risk of inundation. Ten percents of the world’s population who lives in coastal area will be affected. The rising of sea levels also will erode coasts and cause more frequent coastal flooding. This will trigger storms, hurricanes, tornados and typhoons to occur more frequently. In short, global warming will cause topographical change in the earth and the world’s map would have been redrawn.

Besides that, the ecosystem is tremendously disturbed by global warming. Erratic weather patterns lead to an emergence of disease-carrying vectors like mosquitoes. About thirty newly-emerged diseases are also found, for example, Severe Acute Respiratory Syndrome (SARS), Nipah Virus, Ebola, Arena Virus and Hantavirus Pulmonary Syndrome (Al gore, 2007). These diseases are worrying as they are fatal and have the potential to kill vast human population. Rise in temperature is also putting pressure on the ecosystem, the plants and animals that co-exist in a particular climate. Warmer temperature shifted the growing season of flora. Spring which comes earlier forces the migration of animals to start earlier to follow food resources. As the growing season progresses, maximum daily temperatures increase, sometimes beyond the tolerance of the plant or animal. In order to survive in the climbing temperature, both marine, land-based plants and animals started to migrate towards the poles. Species which fail to migrate or adapt will face extinction (Holli Riebeek, 2007). In brief, global warming makes the ecosystem to become unbalanced.

Reducing the emission of carbon dioxide gas is the most practical way to curb climate change. (Christ Woodford 2006). Individuals and government must have consciousness and responsibility towards global warming. Individual can contribute by using energy-saving fluorescent lamps, use public transport or car pooling, and reduce the consumption of electricity especially air-conditioner. Government should find and develop into alternative renewable energy and environmental friendly transport. Government should also invest in correcting climate change as according to a report, it will only cause twenty percents drop in Gross Domestic Product (GDP). Carbon tax is one of the good examples in reducing the emission of carbon dioxide. Authorities should create the awareness among the society via education and campaigns. Every one of us should work together to hinder global warming and save our ailing earth.

All in all, we are witnessing collision between our civilization and the Earth. Ecosystems across the globe are already affected and surprising changes have already taken place. Polar ice caps are melting, plants and animals are migrating, tropical rain is shifting, and droughts are becoming more widespread and frequent. Since greenhouse gases are long-lived, the planet will continue to warm and changes will continue to occur, but the degree to which global warming changes life on Earth will depend on our decisions. Therefore, it is essential that we make the right decision in order to put global warming away once and for all.
