Research Papre - Essay Example This process gets more aggravated when the people cut more trees, which are absorbers of carbon emitted. If we look at history of earth, we can notice that the earth has cooled and heated alternatively in a gradual span of time. The climate of the earth change according to the intensity of sun light receive or due to shift in the orbital movement of earth. However, in the recent times, one force which has alleviated the heating process of earth is humanity. As per (wiscombe,2012)â€Å"The global average surface temperature rose 0.6 to 0.9 degrees Celsius (1.1 to 1.6 ° F) between 1906 and 2005, and the rate of temperature increase has nearly doubled in the last 50 years†. Global warming can be described as a swift increase in the temperature of earth due to a vast release of greenhouse gas into the atmosphere due to the burning up of fossils by humans. The greenhouse effect is a natural phenomenon where in the infrared radiation emitted by atmosphere heat up the planet’s surface. The term â€Å"greenhouse effect† derived from an analogy where the heating up of air inside a greenhouse is compared with the air present outside the greenhouse. Apart from earth, the planets Venus and Mars also experience greenhouse effect. Naturally earth receives heat in the form of radiation from sun and 30% of this incoming energy is solar radiation. The 70% of remaining solar energy is absorbed by the land, ocean and atmosphere of the earth. This natural process occurs in order to give the earth a temperature which is of a stable state and not to allow rapid heating or cooling in the earth’s atmosphere. Generally speaking, only one percent of the earth’s atmosphere is comprised of greenhouse gases .But this greenhouse gas has a feature of trapping heat in the atmosphere and creating a warm blanket of air around the planet. This is what is known as â€Å"green house effect†. Without this greenhouse
