Summary
Role of Human Beings in Global Warming This paper would speak about the phenomenon of global warming, which has now reached alarming proportions on a worldwide basis, and as to why it is primarily attributable to actions of human beings. Some vital facts would also be emphasized in the paper, and which would just go on to strengthen the argument that it is mainly the irresponsible behavior of humans that has paved the way for this unpleasant scenario- a scenario where the entire planet is reeling under the adverse effects of global warming…

Download file to see previous pages The most notable of all greenhouse gases is carbon dioxide, which has the capability to continue being in the atmosphere for a lengthy time span. It is a scientifically proven fact that this gas could bring about a noteworthy rise in the temperature. At this point, it is but obvious to raise the question “No doubt, carbon dioxide is a very potent gas; but how are human beings responsible for rise in the levels of this gas?” The subsequent paragraph would be attempting to answer this. (1) Human beings, purely for furthering their own interests, have brought about a drastic rise in the levels at which fossil fuels are combusted. This has been for the purposes of generating electricity, heating, transportation and cement manufacturing, among many others. It is being estimated that, on account of all these activities, the annual carbon dioxide emissions are approximately 22 billion tons, on a global basis. Almost as a direct result of that, the atmospheric concentration of carbon dioxide has risen by roughly thirty percent. As a matter of fact, these facts are more than sufficient to convince even the most skeptical that it is nothing other than human activity predominantly responsible for heightened global warming. (1) Scientists have estimated that during the course of the last century, there has been a rise in temperature of surface of Earth to the extent of one degree Fahrenheit. The fact has been highlighted that in this very duration there is also a 25 percent increase in the carbon dioxide concentration in the atmosphere. It has been mentioned earlier in the write-up that the enhanced levels of carbon dioxide are chiefly attributable to various human activities. Extensive studies aimed at understanding the link between the above rise in temperature and increase in carbon dioxide concentration came out with a key observation: human activity is mainly responsible for the scenario where the Planet has become warmer. (2) Simultaneously, the scientists also suggested that even some natural parameters could have played a role in global warming. In fact, with regard to the pattern of global warming, the scientists have divided the previous century into two halves. They state that, when the warming of the first half is taken into account, the natural factors must have been primarily responsible for the advent of the phenomenon. This is because; in that particular phase, various human activities resulting in carbon dioxide emissions were on the lower side. But when the second half of the century (1900-2000) is considered, it is but obvious that human beings are the chief contributors to the rise in global warming. In this period, the diverse commercial pursuits of people have led to an alarming rise in the levels of carbon dioxide emissions, and this is a fact beyond any dispute. So, it can safely be inferred that the natural parameters did not have a major role in global warming, with regard to the second part (of the century). (3) The following are some of the activities that have led to the advent of a scenario where, there is a disturbing rise in the greenhouse emissions: various agricultural practices, ...Download file to see next pagesRead More

Global warming

...in industries and transportation (Kowalski 2004 pg 12). Similarly, deforestation, which occurs mainly as a result of urbanization, also causes voluminous release of carbon dioxide into the atmosphere. Thus, it becomes apparent that human actions, to a great extent, contribute to major changes in the climate of earth. Global warming, in simple terms, can be defined as the “continuing increase in Earth’s overall temperature” (Farrar 2008 pg 7). Such increase in temperature, over a period of years, can be disastrous to the living beings on earth and, as such, humans should take all steps to reduce emission of gas to the atmosphere.

Global warming

...dug out as it is naturally in the ground. High human and animal populations naturally imply the need for more food and transport. Because of these two, more fossil fuels are used which means that more greenhouse gases are released in the atmosphere. With a high population, more agricultural activities are done with the aim of increasing the food supply to the growing population. Methane is produced by manure, which is mainly used in agriculture. The increasing populations also use more cars implying an increase in the use of fuels and resultant pollution. According to Silver (2008), carbon dioxide contributes to global warming. The rising level of carbon dioxide from...

...Phenomena The term Global Warming refers to the continuous increase in earth’s average temperature since 1950’s due to human activity and environmental deterioration by various harmful chemicals which are being added to the environment, mainly due to the burning of the fossil fuels. Another term that needs to be defined along with Global Warming is the Green House Effect, which refers to the trapping of heat by the gases such as carbon dioxide, hydrocarbons, water vapors and fuel particles etc. Green House Effect was first considered into study by S. Arrhenius during the last decade of the 19th century when the...

Global warming & human activities

...Global Warming and Human Activities Introduction Humans have understood for over a hundred years the possibility of atmospheric warming due to anthropogenic carbon dioxide emissions. As early as 1896, Swedish chemist Svante Arrhenius predicted that a doubling of atmospheric carbon dioxide would raise average global temperatures by 4.95 degrees C (9.0 degrees Fahrenheit) (Valente, 1995). The greenhouse effect, a natural phenomenon that has allowed the development of life on earth, is thought by many scientists to have been radically altered by humankind’s impact on the composition of the atmosphere. The problem lies in...

...the earth’s temperature (Harding, n.d). However, there is an increased consensus on the role played by human beings in increasing the problem of global warming. Scientific researchers have concluded increasingly that global warming is fundamentally linked to the rising level of greenhouse gases in the atmosphere, mainly methane, and carbon dioxide, as a result of fossil fuel combustion, farming, deforestation, and industrial activities by human beings. This paper critically analyzes whether global warming is due to human actions or not...

Migration of human beings

...Globalization Globalization is generally the world wide procedure of homogenizing products, wages, prices, rates of interest and profit for the sake of accelerating development in the world. There are a number of theories that supports the concept of globalization in the world today. Migration of human beings support globalization since when people move to another place, they tend to carry with them their culture to the new location which is in imitated by the others. With this kind of interaction, some behaviors are seen to have integrated together which with time harmonizes them. International trade is another factor that is seen to be supporting globalization in the world today. When people from different parts of the world... are...
