Participation of human activities to global warming


It is known that the temperature of the atmosphere is warmed through a natural process called the green house effect. The natural process warms the earth's surface up to a certain level where every specie and human being can live adequately. Unfortunately, the green house effect has been increased by human activities that have caused higher temperatures and unusual climate changes throuhout the world giving birth to global warming. Fuel burning and deforestation are two main causes that increase the quantity of greehouse gases, both manmade causes.



The problem seem to persist, deforestation and fuel burning are not being stopped at all. Although many organizations have got together to discuss and find a solution to the problem, nothing has really happenned. Perhaps one reason why human activities have not stopped is because there are also scientist and polititians who claim that there is not global warming at all, and that the temperatures are the cause of natural cycles that have been going on for thousands of years. However, scientist have proven that during the 20th century the atmospheric temperature rose 1.1f (0.6c), and sea level rose several inches. Scientist have also proven that since 1988 the planet is getting warmer due to the increase of carbon dioxide. Carbon dioxide has also been increasing since 1960 due to the industrial revolution which consisted of human activities as agriculture and fuel burning. Human activities again, increasing carbon dioxide, making an alteration on the regular carbon dioxide that comes naturally, creating like that global warming
