Global warming is not only a great threat to the economic well-being but also the existence of human's civilization. Every year, there are many extremely powerful natural disasters, which are always nightmares for human. Fox example, in 2004, the double disasters it Japan took the lives of thousands people and leave the country nothing but the huge challenges to rehabilitate. People may think that natural disasters are caused by nature and there is nothing can do to prevent them happening. In fact, every person can each play an important role in stopping global warming. What is Global Warming? Global warming is the term to describe the gradually rising of the temperature all over the world as a result of the creation of gases that trapped energy; its included carbon dioxide and methane which are mostly cause by human. That change is believed to be permanently changing the Earth's atmosphere forever. A warmer Earth may lead to changes climate pattern, extreme weather event, rising sea level, and a huge impact on plants, animals and human. The scientists generally agree that "the average temperature of the Earth has risen between 0.4 and 0.8 °C over the past 100 years.  (see livescience website source). "Scientists from the Intergovernmental Panel on Climate [also] predict that average global temperatures could increase between 1.4 and 5.8 °C by the year 2100" (see livescience website source). Creation of gases such as carbon dioxide and methane is the main cause of global warming. Since the Pre-Industrial era (in the late 18th century), human have used more energy, mainly from fossil fuel sources such as coal, oil, or gas, which released into the atmosphere an enormous amount of greenhouse gases. "Carbon dioxide is the most important long-lived global warming gas, and once it is emitted, a single CO2 molecule can remain in the atmosphere for hundreds of years  (climate central source).
