Global Warming is Manmade - Essay Example

Global Warming is Manmade Global Warming is Manmade Scientists have demonstrated indisputably that human beings have a profound effect on climate change and global warming. The facts, figures, statistics and other scientific evidence point to the fact that above anything else, the causes of global warming are mostly anthropogenic. There is wide acceptance among all scientists that there are gases which have a general effect of causing a rise in temperature over the earth because they impose what has been known as the greenhouse effect.

These gases, also called greenhouse gases, when emitted in large quantities, have the effect of “blanketing” the earth, thus causing a reduction of heat loss to the outer space from the earth. Scientists have implicated this phenomenon in causing the general rise in temperature that is global warming. The objective of this essay is to outline the various ways in which human activities generate the gases that are primarily responsible for global warming, and also argue that global warming is mainly due to the effect of human activities.

Keywords: global warming, anthropogenic, greenhouse effect. Greenhouse gases.Activities That Increase CO2One of the major anthropogenic causes of global warming is the use of fossil fuels in industries and transport (Nardo , Don; Johnson, Roberta; Young, Terrence Jr. E, 2008). Fossil fuels, when burned, produce carbon IV oxide. Carbon IV oxide is a dense gas, and when emitted, it blankets the earth, helping to retain the heat on the surface of the earth. This, over time, causes an increase in the temperatures on the surface of the earth, leading to global warming.

There has been widespread controversy over whether human industrial activity fosters global warming. Some skeptics have come out to proclaim that global warming and climate change are largely natural events that do not need human input so as to manifest themselves (Alexander, Ralph B, 2009). They argue that even in the absence of human activities, global warming would still be a reality. The skeptics have gone so far as to claim that the statistics provided by scientists are all part of a hoax.

However, there is sufficient scientific evidence to pin down these skeptics as to the truth of whether or not anthropogenic activities contribute to global warming.Another cause of global warming is deforestation. The rate at which forest trees continue to be felled contributes significantly to global warming. Trees help eliminate carbon IV oxide from the atmosphere. When forests are disturbed, the practice interferes with this natural source of carbon IV oxide management. Therefore, carbon IV oxide levels continue to rise unchecked.

This eventually leads to high atmospheric carbon IV oxide levels that exert the greenhouse effect on the globe, and thus cause global warming.Activities That Increase MethaneMethane is the other significant greenhouse gas because it is in relative abundance as compared to the other greenhouse gases. There are also human activities that give rise to an increased level of methane in the atmosphere. Mining is one of them. Mining causes a disturbance in the balance of methane in the atmosphere because when mining out fossil fuels, the miners also encounter methane (challenge.org, 2012).

Methane is, therefore, released to the atmosphere in large quantities, and this leads to the greenhouse effect. Therefore, mining, especially mining of petroleum products, could secondarily cause a rise in global temperature by the release of substantive amounts of methane into the atmosphere.Farming is yet another mentionable, if minor, cause of global warming. People who practice animal husbandry usually produce methane gas as a bio-fuel that helps them save fuel costs. Moreover, the processing of manure also leads to methane gas production.

A whole range of farm activities could be implicated for an increase in the levels of methane gas. The situation is augmented by the rise in population, hence the need for increased food production, and, subsequently, the need to heighten farming activities.Although there are other human activities that may cause a rise in global temperatures, and other gases apart from carbon IV oxide and methane that could be implicated in the same, the ones mentioned above are the most significant. Global warming is, indeed, predominantly caused by human influences.
