A Sample Essay On Global Warming:
Global warming has over the past decade received great attention due to the impact it has had on both humans and the environment based on the scientific theories that have been discovered and put into place that give evidence as to the happening of global warming therefore the need to come up with effective ways and methods of combating it.
Global warming also referred to also as climate change has been defined as the overall rise in air and ocean temperature resulting from the greenhouse effect that which comes as a result of high levels of chlorofluorocarbons and carbon dioxide (Oxlade, 2003).
The global warming phenomena has had scientific basis as to its occurrence which will be discussed in the above context. The climate of earth has changed over the decades in which there have been several cycles of glacial advance and abrupt end of the last ice ago during the era of human civilization .Most of these changes in earth climate was attributed to the small variations in the orbit of earth that changes the solar amount received. This puts into issue that the scientific basis and evidence of global warming is equivocal.
Satellites that orbit the earth and technological advances put in place by scientists has enabled them collect more material information about planet earth and its climate on a global scale. Some of the scientific basis that attribute to the fact that global warming is did real range from the 19th century when the heat trapped and carbon dioxide was observed and the scientists had the ability to transfer infrared energy through the earth atmosphere through the instruments that were flown by the scientists who were of the general view that the increase in greenhouse gas level was the ultimate cause as to the warming of the earth atmosphere (Karl & Trenberth, 2003).
Another basis that is scientifically proven to point that global warming in fact do happen can be traced from the ice cores obtained in Antarctica and tropical mountains glaciers which give evidence that the climate of Earth planet responded to changes in the solar output in its orbits which further evidenced that large climate changes happened quickly based on the year span. Out of this scientific basis most scientists were of the view that the global warming effect over the centuries has been due the human activities and that the emissions of heat-trapping greenhouse gases such as carbon dioxide were viewed to be the dominant cause of global warming. Other scientists were of the basis that global warming had been happening globally and with a country like the United States signs such increase in air and water temperature, reduced frost days, intensity of down pour and its frequency, reduced snow cover, sea ice and reduced snow cover were evident enough to show that climate change has been happening over the years.
Based on the scientific studies there was a series of popular scenarios that gives the assumption as to climate change such as rise in sea level due to thermal expansion, drying of tropical dry zones such as Mediterranean Basin, incraesed rain intensity and frequency, increase in Arctic region temperature, and ocean acidification (Houghton,2009).
The above theories have one thing in common that the climate change has been due the human activities hence leading to this warming in that more emissions of heat trapping gases are from human activities which have increased the global temperatures based on the presence of human fingerprints on carbon to which when coal, oil and gas burn they generate carbon dioxide.
Carbon dioxide is the main heat-trapping gas and responsible for most of the warming. The human activities of human of industrialization have seen the emission of these gas onto the atmosphere thereby forming blanket through clogs.Generallythe human climate drivers range from heat-trapping emissions that come from gas,coal,oil in cars, cutting down of trees, burning trees as charcoal, aerosols have led to albedo and resulted to net warming and cooling. In general the human activities that have resulted to the atmospheric greenhouse are mostly from the burn of fossil fuel that causes the heat to build up in the atmosphere.
With most of the global warming being caused by human activities there is a clear distinction between natural and anthropogenic climate changes. To which anthropogenic refers to the human induced factors of climate change while the later refers to the natural causes that are not induced by humans (Zhang, Brecke, Lee & Zhang, 2007)..
The natural induced factors have been made through scientific observations such as the Arctic and Mediterranean areas while anthropogenic factors are human induced activities that contribute to global warming such as green houses and its gases,, chloroflourocarbons,, aerosols in the climate that scatter and absorb solar energy and change the microphysical and chemical properties of earth,dust,industrial proceses,exhaust emissions, land usage while the natural factors are mainly triggered by the sun which triggers the release of greenhouse gases, orbital changes, increased global temperatures are some of the factors that contribute to the problem of climate change.
Based on the above arguments global warming seems to be taking place based on the anthropologic human factors that lead to emissions such as the green house that emit vapours,the burning of fossil fuel such as oil that produces gas, availability of chlorofluorocarbons and aerosols into the atmosphere. The effects of global warming can be felt in some parts of the world due to temperature trends. On the other hand there are views that global warming is not happening in that the planet has always been flat and no consensus globally that is caused by man and that it has been always over and over and the predictions as to the impact of the effect of global warming have been proven wrong by some scientists.
Due to the rising effect of the climate change there has been mitigation strategies put in place to combat the problem of global warming ranging from carbon sequatration, carbon taxing, clean coal technology and the use of high fuel efficient standards in order to avoid the effects caused by the change in climate (Karl & Trenberth, 2003).
Carbon sequestration refers to the scientific process of capturing and storing the carbon dioxide gas by removing it in the atmosphere and depositing it into areservoir, removing it from gases thereby recycling it to avoid emitting it into the atmosphere. The above process if done through biological process tends to affect the carbon cycle such as due to climatic fluctuations and engaging in activities such as re a forestation and wetland restoration.
Some of the common sequestration methods employed range from a biotic that includes oceanic and geological injection, biotic sequestration and terrestrial sequestration.
Carbon taxation on the other hand refers to the process of levying on carbon contents of fuels especially hydrocarbons that release carbon dioxide such as petroleum, coal and natural gas hence avoiding the release of green house gases into the atmosphere. Such method is cost effective as it helps to address the problem emitters of green house gases by facing the cost of their actions. They are efficient in that they can lead to employment.
The mitigation strategies have on one hand been effective in various jurisdictions such as the carbon taxing done of fossil fuels which has seen the emitters face full force for their acts and create employments while on one hand mitigation such as the clean air technology has been seen as expensive to implement as to the tapping of the gas. The best policy that I would regard is the carbon sequestration and high fuel efficient standards that would limit the emission of carbon dioxide into the atmosphere. The business sectors that are likely to be affected are the manufacturing sectors, agricultural sectors and industries in areas such as China who would be forced to pay for their actions of emitting carbon dioxide into the atmosphere.
