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

Global warming is no longer a future fear, instead it is happening now. (Riebeek, 2007) With some countries like China and India which are developing at an increasing speed, there is a big boost in the number of factories and vehicles. Billions of tons of greenhouse gases, namely carbon dioxide, are emitted into the atmosphere, causing the thermal radiation to be trapped in the earth. Thus, the earth has warmed and climate change occurs. Unequivocally, there will be potential effects of global warming in terms of climate change like rising of sea levels, frequent happening of natural disasters and disorder of the balanced ecosystems but people can cut down the carbon dioxide emissions to arrest those problems.

One of the effects of global warming is the sea-level rise. It happens when the oceans get warmed up and the water expands. The melting of mountain glaciers and ice sheets has also contributed to the rise. According to Riebeek (2007), the rising sea levels will erode coasts and cause more frequent coastal flooding. This is a great threat for people who live in coastal areas less than 10 meters above sea level, for instance in Florida, California or Bangladesh. Although the sea levels are only rising 3cm per decade, it is massive enough to let the houses disappear underwater.

Another effect of global warming is that natural disasters will happen more frequently. Examples of those disasters included destructive storms, flash floods, widespread droughts, hurricanes and tornadoes. When the ocean gets warmer, it causes stronger storms. As the water temperature increases, the wind velocity increases and the moisture content increases. (Gore, 2007) Thus, Hurricanes Katrina formed in Florida at 2005. The consequences are pernicious. People are losing their properties, family and friends. Besides, heat wave also happened in Europe at 2003 which caused an estimated death of 35,000 people. In short, scientists expect that the erratic weather patterns will lead to more sufferings of people in earth.

Furthermore, global warming also affects our balanced ecosystems. Plants and animals grow well in the balanced four seasons. However, global warming leads to the earlier coming of spring and later of fall. Animals need to migrate earlier and plants need more water to withstand the longer growing season. If the temperature keeps on getting higher, the animals and plants which cannot adapt will face extinction. On the other hand, global warming also melts the ice sheets. The polar bears, which depend on the ice, will soon face extinction too. In short, global warming is putting pressure on ecosystems. (Riebeek, 2007)

In order to reduce global warming, people should lessen the emissions of carbon dioxide. There are many ways that an individual can do. For example, buy energy efficient appliances and lamps that reduce energy for heating. It is also better to walk, use bicycle, public bus or hybrid car to travel from one place to another. (Woodford, 2006) People should also switch to renewable sources of energy instead of fossil fuels which would emit large amount of carbon dioxide. Besides, use less electronic appliances to save energy. Open the window instead of turning on the air-conditional. In other words, every individual can help to cut down carbon dioxide emissions by small practices.

In conclusion, global warming in terms of climate change has devastating potential effects and they must be arrested. It will lead to sea-level rise, frequent happening of natural disaster and disorder of the balanced ecosystems. Reducing the carbon emissions will help to solve the problems. In fact global warming has been happening many years ago and most importantly it is irreversible. It is a good thing that we have the awareness of reducing global warming. However, in the meantime, we should adapt the climate change that happens. (Carter, 2008)

Good effort.To improve, please consider the following.


Please check the citaion. write the surname and the year without a comma. for the movie, write the name of the movie and the year instead of the character's name.
