lobal warming is the gradual increase in the temperature of the earth's atmosphere. The increase of temperature is due to the greenhouse gases such as carbon dioxide, water vapor, nitrous oxide and methane which trap heat and light from the sun in the earth’s atmosphere. When living organisms fail to adapt to the current temperature, they faces disposal. When trees are cut down or fossil fuels are burn, they release carbon dioxide into the air which increases the greenhouse effect. Mass deforestation in the world at an unprecedented rate worsens the problem. Even without the contribution of human activities, the earth has been experiencing climate change in the past. Now, the climate has become more serious due to the involvement of human activities. Global warming also is the current climb in the average temperature and is projected persistence. The scientific research shows that global warming is initiated by human activities such as regular melting of glaciers.

        One of the contributors of global warming is burning of fossil fuels. Fossil fuels are produced from the decomposition of dead organism for many years. Examples of fossil fuels are coal, petroleum and natural gas. When these fossil fuels are being burn, carbon dioxide will be release. Other than that, chlorofluorocarbons (CFCs) gas that releases from the refrigerators and air-conditioners have contributed to the depletion of the ozone layer. The depletion of ozone layer will cause incentives sunlight to enter and cause a rapid rise of temperature on the earth. The effect of it could be seen by the example of ...
