Global warming is the past ten years an item of debate though, the one thing agreed upon is that the earth is hot. A pleasant definition is the one that tells us that greenhouse gases are the cause of the warming of the earth. The controversy continues into the cause of global warming and how it will ultimately affect the earth. There is even some controversy as to whether it exists. There is no argument as the rise in the earth's temperature rose in the past hundred years, from 0.45 to 0.06 degrees Celsius. The controversy caused by those who believe and those who are skeptical. Feel those who believe that greenhouse gases like carbon dioxide in the atmosphere is a shield that traps the heat inside the atmosphere. Temperature rise when increasing carbon dioxide in the atmosphere See chart. In the earth's temperature will cause the ice caps to melt and sea levels rise. The earth's coastline will wash away and there is a fear of the disease to human life and wildlife. Those who do not feel that global warming is not a problem for the environment and the increase in the earth's temperature is not a concern. The earth's coastline will not disappear and the ice caps. This graph shows that temperature rises in the middle of the twentieth century the distribution of carbon dioxide. The graph also shows the temperature fluctuations over time. Arguments whether it exists or does not exist much. The believers in global warming felt that they prove its existence by using computer climate models. The believers state that these models are not based on facts and is therefore not reliable evidence. And so the arguments with one faction remains declare that global warming is something we should be concerned about and is an issue that is not taken lightly, and the other faction declared that global warming is a natural phenomenon and that there is no cause for alarm .
