Global warming is a controversial topic and until now, our Earth is getting warmer day by day. Global warming occurs when solar radiation passes through the atmosphere in the form of light waves. The radiation is absorbed by our Earth and warms it. The warming planet radiated back into the space in the form of infrared waves. However, some of this outgoing radiation does not pass through the atmosphere, but it reflected back down to Earth. Thus, the heat energy is trapped by the atmosphere and increases Earth’s temperature. As a result, global warming had caused some effects in term of climate change.
Firstly, the effect of global warming to the Earth is the climate change. As we all know, global warming releases greater amounts of carbon dioxide to the atmosphere. The concentration of carbon dioxide in atmosphere now is above 300 parts per million (Al-Gore, 2006). Temperature of Earth increases as the atmosphere traps more heat. It significantly changes the usual climate across the globe. As the result, some place faces higher temperature, some place faces lower temperature and even hurricane and storm hit some part of the Earth. For example, America was hit by terrible hurricane Katrina in 2005 and had caused a lot of destructions.
Secondly, global warming also affects the level of the seas. It is because when the temperature of Earth increases, the temperature of the oceans increases too. The level of the seas also increase when the melting of glacier and ice sheet is occurs. The amount and the thickness of the Arctic’s ice cap is decreasing 40% in 40 years (Al-Gore, 2006). Thus, it means that some part of the world will be disappeared especially the low country because as the ice cap from North and South Pole is melting, the volume of sea water will increase. Tony Blair’s scientific advisor (n.d) argues that the world map would have to be redrawn if global warming is not reduced.
Another problem is pests and diseases are predicted to spread much faster. For example, mosquito breed faster in hotter temperature and more people will be affected by malaria. The number of cases of infected diseases will be increased in the countries that are located just above the mosquito’s lines such as Nairobi. In addition, 30 news diseases are founded in the last quarter of century (Al-Gore, 2006). SARS, lyme diseases and Avian flu are the diseases that causing havoc throughout certain countries especially poor countries. It is believes that the number of new infected diseases will rise as the Earth is getting warmer.
A final problem caused by global warming is that many species are now threatened with extinction and the ecosystem is disturbed. With the faster increasing change of temperature, animals and plants may not be able to adapt quickly enough and many of the species become extinct. For example, polar bears depend on sea ice to hunt and move from one place to another. If all the sea ice is melts, it is afraid that the polar bears may not be able to survive. At the end, our next generation may not be able to know what polar bears it is.
Global warming can be reduced if we are able to produce fewer carbon dioxide emissions. The easiest way to start is by plant more trees. Trees release carbon dioxide to the air. It means that, more trees will release more carbon dioxide to the air and lower the temperature of surrounding. Walk or ride a bicycle is the easier way to practice, significantly reduce the emission of carbon dioxide to the air. We also can buy energy efficient appliances and stop using air conditioner that releases harmful gases to the atmosphere.
As conclusion, global warming causes havoc across the globe. Global warming affects the climate and the level of the seas. The number of infected diseases increases as global warming becomes worse. Extinction of species and the disturbance of ecosystem are among of the effects of global warming. In order to reduce the carbon dioxide emissions to the atmosphere, various ways are suggested but we have to start from the easiest. Our small action will make a big difference.

hye guys....please spend your time to read my essay....leave your comments as many as you can...learning is something impossible to be stopped..
in my opinion, the essay is well written and easy to understand. there is a clear introductory sentence and all points are connected. the paragraphs have sufficient supporting details and the conclusion summarize all the main points given in the essay. the sources are cite adequately and appropriately and there are no apparent grammatical or spelling mistakes. good work :D
for 2para...there is misconcept about global warming. global warming doesnt release carbon dioxide. the carbon dioxide itself causes global warming.
there is some grammar mistake that u can improve and use the right words ie for 4para affected-infected, 6para reduced-controlled/redressed
do not add ur own opinion such as the last sentence for 5para.
there is insufficient citation. u have 2 use all the 4 sources given.
There are no citations in your 1st paragraph which makes people to wonder it is your own opinion.
There are no thesis statement, please take note of that as it is a MUST to have a thesis.
Your points per paragraph are insufficient and you have so many paragraphs, i suggest that improve some paragraphs and join them up together into one.
You did not give citation of the articles which you have paraphrased in most of the paragraphs.
Your citation for the Al-Gore video is wrong, use the one that Miss Dil posted up in her blog.
AND THERE IS ONE BIGGEST MISTAKE!!! your 2nd last paragraph!! since when did you learn that trees release carbon dioxide into the atmosphere??! and how can you say trees release carbon dioxide as a way to reduce global warming when carbon dioxide should be reduced??!! BE CAREFUL OF WHAT YOU ARE TYPING.
p/s: please don't trust azam's comment. i can't believe he just wrote that, or he really didn't realize any mistake in your essay
hi Akmal,
I've read your essay and there are many grammatical errors that need to be corrected.
I could not proof read your essay now as it is quite late now and i need more time to read and correct your sentences. Check your plural forms and singular forms. for example;
'mosquito breed' should be changed into 'mosquitoes breed'.
And you should support your facts by making citation.
