Global Warming and Deforestation Global warming is an issue that individuals must be knowledgeable about. To gain understanding of this vital concept, one must first explore the factors that cause it. One of the major reasons that speed up global warming is deforestation, which is the removal of trees in the forests as term implies.
Keywords: Global warming, deforestation
Global Warming and Deforestation
Global warming is a detrimental result usually brought about by human activities that have a negative impact to the environment. Global warming is caused by the substantial upsurge in greenhouse gases such as carbon dioxide, which humans are putting into the atmosphere (Maslin, 2007). One of the major factors that contribute significantly to global warming is the burning of fossil fuel, which has amplified the levels of atmospheric carbon dioxide to their highest for the last 20 million years. This paper, however, will focus more on another factor that also play a crucial role in global warming, which is deforestation (Maslin, 2007; Humphreys, 1996).
Global warming can be hastened by a variety of factors, one of which is deforestation. Deforestation is the result of human activity such as illegal logging which is damaging to the ecosystem. The effects of deforestation as stressed by Humphreys (1996) range from the global to the local level. One of the most essential implications of deforestation is its impact on the dilapidation of the atmosphere (Humphreys, 1996).
Deforestation plays a crucial role in global warming, which transpires from elevated concentrations of greenhouse gases resulting to net escalations in the global mean temperature (Humphreys, 1996). Radiative forcing is the atmospheric process by which greenhouse gases amplifies temperature increases according to Humphreys (1996).
To gain insight on how deforestation partake a role in global warming, it is beneficial to explore how this process really works. Greenhouse gases are composed mainly of four gases namely, carbon dioxide, methane, nitrous oxide and chlorofluorocarbons (Humphreys, 1996). The effects of global warming are deemed to be hazardous to the planet Earth. It was predicted that intense global warming will cause alterations in global trends of agricultural productivity, augment melting of the Arctic and Antarctic ice caps, thermal spreading out of the oceans and a net proliferation in sea levels which would endanger coastlines worldwide (Humphreys, 1996). Humphreys highlighted that not only does deforestation play a part in global warming but as a result, global warming would remarkably be perilous to nature, the warming of the oceans will be a menace to marine life, while climatic zones are supposed to move towards the poles, thus, will be detrimental to weak ecosystems (1996).
A variety of research studies have been conducted to determine the link between global warming and deforestation. One of the major research reports that was conceptualized was the Scientific Committee on Problems of the Environment or SCOPE 29, which tackled mainly the impact of global warming and the contribution of deforestation in elevated levels of carbon dioxide (Humphreys, 1996). As highlighted in the SCOPE 29 report, emissions resulting from human activities are evidently boosting atmospheric concentrations of the greenhouse gases, which in turn will enhance the natural greenhouse effect, resulting on further warming of the Earth’s surface (Humphreys, 1996).
It is also apparent that an area seemed to be warmer without the trees which were previously covering it for the reason that the trees that were once present there do no longer provide a shelter and cover from the heat of the sun. It is also known that trees are the ones producing oxygen and absorbing carbon dioxide in the process of photosynthesis so when forests or any area are deprived by trees, the carbon dioxide in the atmosphere can no longer be manufactured into oxygen for there are no trees or plants that will facilitate photosynthesis (Humphreys, 1996).
Learning the link between global warming and deforestation is crucial for individuals so that people will be aware of the detrimental and perilous impact of their activities. Thus, they will be more cautious with their acts for if they are not, it would cause them the planet they are living in and before one knows it if hazardous activities continue, the Earth will cease to exist.

...Introduction: The term ‘Global Warming’ refers to the continual increase in earth’s average temperature since 1950s due to the human activity and environmental deterioration. A term closely associated with the global warming is the Green House Effect which is the trapping of heat by the gases such as carbon dioxide, hydrocarbons and fuel particles, water vapors etc. Green House Effect was first studied by S. Arrhenius in the last decade of nineteenth century. The effect is explained in the following lines. Sun is a continuous source of energy for our earth and its energy reaches the earth in form of electromagnetic radiations. A part of these radiations is absorbed by...

...? It is no doubt that Earth is warming faster than ever before in history. The slowly increasing temperature is however, thought to come about because of the various human activities. Global warming occurs because of the massive greenhouse gases for instance carbon dioxide and methane. Human activities are the main cause of the increase in green house gases. For the last 20 million years, research has it that burning of fuels has tremendously given rise to high carbon dioxide level in the atmosphere. A recent report by Intergovernmental Panel on Climate Change shows that there is a vivid evidence for 0.6 degrees Celsius increase in global temperatures and about 20cm rise...

...GLOBAL WARMING Introduction: In 1896 a Swedish scientist put forth the position that burning of fossil fuels causes accumulation of Carbon Dioxidein the atmosphere, which in turn creates a “greenhouse effect” and elevation of global temperatures. In the 1950s, the notion of global warming cropped up again when G.S. Callender highlighted the dangers of the greenhouse effect (Weart 2003). Weather models developed in the 1960s led to the discovery that the levels of certain gases were rising, degrading the fragile ozone layer in the atmosphere. The summer of 1988 was the hottest one on record with temperatures rising ever since and concerns about...
