Global Warming Too Hot or Not

The hypothesis of this essay is that global warming is man-made, and implications of global warming indicate negative outcomes in several aspects of human, plant and animal life. The findings from informative sources will be documented and discussed, and conclusions will be drawn in relation to the hypothesis given.
The leading theory on global warming is that human industrial activity over the last century is the root cause of global warming since it has been causing carbon dioxide emission into the atmosphere. Similarly, modes of transportation such as cars and buses increase the emission levels. Further, the burning of fossil fuels and clearing of forests result in the production of carbon dioxide and other heat-trapping gases, which remain in the atmosphere for several decades and even centuries (Behrendt: 10).
The accumulated gas prevents heat in the atmosphere from escaping into space, and the retained gas causes a rise in the environmental temperature, which is termed as the greenhouse effect. This increased release of greenhouse gases caused by human activities causes the retention of more heat than normal by the earth. The main reason is that carbon dioxide absorbs the earth’s heat radiation and acts like a blanket over the earth’s surface (Houghton: 9). The increased atmospheric warming results in activating natural processes that cause greater release of greenhouse gases which are deposited in the atmosphere. Michaels (p.50) states that “planetary near-surface temperature has increased by approximately 1.5 degrees centigrade over the past century, and will continue at a higher rate for the next century”.
The United Nation’s Intergovernmental Panel on Climate Change (IPCC) and other major scientific bodies such as the American Meteorological Society, the American Geophysical Union, and the American Association for the Advancement of Science support the above theory.
