Man-Made Global warming

Thesis: Man-made Global Warming is a major issue that effects the environment, people, and the world, and if it is not stopped now, the results could be catastrophic.

  1. Background
  2. Dispute

Global warming is one of the most significant issues in today’s society because it is causing super storms, droughts, heat and waves. Man-made global warming is a major influence on extreme weather. For instance, burning coal, oil and natural gas releases carbon dioxide gas into the atmosphere. Destroying forests and cutting down trees also has a detrimental effect on the earth’s atmosphere and weather. It has been documented that the environment is continuously deteriorating. The fast growth of industries has lead to increased air pollution and the depletion of the ozone layer. According to statistics, the ozone layer is deteriorating and soon human beings will have to cover their whole bodies while walking in sunlight because of the direct radiations from the sun (Adam 97). Global warming is currently happening and scientists have documented proofs that human beings are to be blamed. For so many years, cars and industries have been spewing many tons of greenhouse gases into the atmosphere which have lead to the rise in the atmospheric temperature. The rate of warming within the past 50 years was two times the rate observed over one hundred years ago. Temperatures are likely to continue rising (Rlebeek 1)

  • Definition of Global Warming

Global warming can be defined as the increase of the earth’s mean surface temperature as a result of the effect of the accumulation of greenhouse gases in the atmosphere. The greenhouse gases, which include carbon dioxide and methane causes global warming through the absorption of heat that would otherwise escape from the earth. Since the 1880, the earth’s mean temperature has increased by approximately 1.4 Fahrenheit and is continuing to increase. Global warming had been observed to be one of the greatest environmental issues within the past two decades. In accordance with the reports by the Environmental Protection Agency (EPA), the surface temperature has risen by approximately 0.8 degree celsious over the last century. Over half of this increase has occurred within the past twenty five years. This implies that, surface temperature is increasing at a very fast rate (Dessler & Edward 2). Human activities like the burning of fossil fuels, deforestration, industrialization as well as the general environmental pollution are considered as some of the major factors contributing to global warming.

Global warming begins when sunlight reaches the earth’s surface; about 30% of it is normally reflected back by the clouds, the atmospheric particles, the ocean surface or even the reflective ground surface. The remaining about 70% of the sunlight is normally absorbed into by the land, air and water bodies which heat the atmosphere, making life bearable on earth. The energy from the sun does not usually stay permanently within the earth’s environment. Rather, as the rocks, the air and the water bodies warm, there is normally the emission of thermal radiation or what is also referred to as the infrared heat, much of which travels straight out to the space which allows the earth to cool (Dessler & Edward 3).

  1. Cause of Global Warming
  2. Emissions from:
  3. CO2

Human activities such as burning of fossil fuels normally results in an accumulation of greenhouse gases in the atmosphere. As the atmosphere becomes thicker, more heat is trapped in. fossil fuel like lubricate, petroleum and natural gases are very high in carbon dioxide and when put on ablaze, produce great amounts of CO2. Carbon dioxide constitutes about 72% of the total emitted greenhouse gases. It is thus the most important cause of global warming. In most cases, CO2 is as a result of burnt fuels such as oil, natural gases, petrol, and ethanol among others. The emission of the gas has greatly increased within the past 50 years and has continued increasing by approximately 3% every year. The CO2 released to theatmosphere normally remains for upto 200 years. It remains in the atmosphere for longer periods as compared to the other key heat trapping gases that are normally emitted as a result of the activities by human beings. The long time existance of CO2 the atmosphere gives the most clear probable rationale for the reduction of CO2 emissions without interruption.

  • Water vapor

This is the most plentiful greenhouse gase as well as the most significant in terms of how it contributes to the natural greenhouse effect, regardles of having as brief atmospheric life span. A number of activities by human beings can increase the level of atmospheric water vapour. But on a universal scale, the amount of water vapor is controlled by the atmospheric temperature, which is influencing the average rates of evaporation and precipitation. Thus, the universal concentration of water vapor is not usually substantially influenced by direct human activities. The quantity of water vapor in the atmosphere is directly proportional to the atmospheric temperature. If the atmospheric temperature rises, increased amounts of water evaporate and turn into vapor. And because water vapor is a greenhouse gas, the extra water vapor results in an increase in temperature. Studies indicate that water vapor approximately doubles the quantity of warming that is caused by carbon dioxide. Water is usually evaporated from the land and ocean surfaces and thereafter falls as rain or snow. Therefore, the quantity held within the atmosphere as water vapor normally varies significantly within a few hours because of the prevailing climate condition of any region. Therefore even if water vapor is one of the major greenhouse gases, it is has a very short life span in the atmosphere.

  • Emissions from
  • Exhaust emissions from vehicles

The combustion processes that normally power most vehicles usually result in the generation of CO2 is considered the key cause of global warming. More that 90% of the newly sold vehicles still utilize internal combustion engines and in accordance with the Department of Energy, this is bound to continue to be a fact for the predictable future. These kinds of engine typically mix up oil with the air present in the ignition chamber. The mix then burns when it catches fire, emitting large percentage of energy and leaving being water vapor, CO2 as well as other gases as waste products (Haldar 12). The vehicles exhaust system releases these wastes into the atmosphere which then becomes a part of the atmosphere. The replacement of the utilization of fossil fuels by vehicles with other forms of technology may assist in the reduction of the amount of atmospheric carbon dioxide. Hydrogen fuel cells is a suggested form of energy technique that can effectively be used in place of fossil fuel since it only produces electricity and water vapor. The hybrid electric cars usually produces very low amounts of CO2  as compared to the traditional vehicles for the reason that they make use of the smaller engines and  only run them when necessary (Haldar 13).

  • Nitrous oxide

Nitrous oxide is one of the greenhouse gases usually formed naturally and also results from some of the activities of human beings. Nitrous oxide concentration in the atmosphere has augmented by approximately 15% since the time of industrialization. Agricultural activities are considered as the key source of nitrous oxide. Livestock production contributes about 2/3 of human associated nitrous oxide in the atmosphere. Industrial sources produce about 1/5 of the overall anthropogenic nitrous oxide and it constitutes the manufacture of nylon and fossil fuel ignition in internal combustion machines. Nitrous oxide also regarded as the laughing gas, is graded the 3rd behind CO2 and methane in causing global warming. Nitrous oxide is about 300 times more efficient in trapping heat as compared to (Haldar 20).

  1. Effects of Global Warming
  2. Increasing temperatures

Greenhouse gases including CO2, methane and nitrous oxide trap heat in the atmosphere, which results in an increase in the average atmospheric temperatures. Temperatures have continued to increase within the past 30 years and the year 2001 and 2010 were marked as the warmest years. The earth gets warmed, the heat waves become more common in some regions. Heat waves normally occur when an area is experiencing very high temperatures for a number of days and nights. The choices made by human beings today and within the next few years will determine how much the earth’s temperature will increase. Higher temperatures imply that heat waves are likely to occur more often and last for very long periods. Heat waves can be hazardous, and cause diseases such as heat cramps as well as heat stroke and sometimes even death (Pilkey 15). The increasing atmospheric temperatures have resulted in:

  1. Ice melting worldwide, especially at Earth’s poles

The increasing global temperatures are speeding up the melting of ice and glaciers and as a result causing ice thaws on large water bodies. The ice cover of the Earth is melting globally at very high rates. Research has indicated that global ice increased in the 1990s which was recognized as the warmest decade. According to scientists, the increased ice melting is among the observed human influenced global warming that has been as a result of unprecedented emission of CO2 as well as other greenhouse gases over the past years. Glaciers as well as other ice features are mainly sensitive to temperature changes (Pilkey 53). The ice on the earth’s surface is acting as a protective mirror responsible for the reflection of large amount of sun’s heat back into the space ensuring that the earth experiences a cooling effect. Loss of this ice can greatly affect the global climatic conditions and also raise the sea level. As a result of the increase temperatures, the Arctic sea that covers approximately the size of US, reduced approximately 6% between the years 1978 and 1996 resulting to a loose of an average of 34,000km2 (Mastny para 4).  At the earth’s poles, large amounts of ice melt has taken place in mountains as well as the subpolar glaciers which have been responding more quickly to temperature variations. Generally the world’s glaciers are shrinking as faster rates that they are growing. According to scientists, ¼ of the global mountain glacier mass is likely to vanish by 2050 and up to ½ by 2100 leaving large patches in regions such as Alska, and Himalaya

  • Sea level rise

According to the tide gauge readings and the current satellite measurements, the global mean sea level (GMSL) has by about 4 to 8 inches which is approximately 10 to 20 centimeters. Though the annual increase rate over the; last 20 years has been approximated at 0.13inches which is approximately 3.2 millimeters. Over the last century, the flaming of fossil fuels in addition to other activities by human beings has resulted in the emission of great amounts of greenhouse gases into the atmosphere which as consequences have led to an increase in the earth’s temperature and the ocean has been absorbing approximately 80% of this additional heat (Pilkey 16).  These level rise is linked to 3 key features all influenced by the continuing global climate change including thermal expansion, melting of polar ice and glaciers and the loss of ice from the Greenland and west Antarctica.

  • Reduction in number of animals

The present trends of global warming is resulting in the occurrences of the physical as well as biological changes globally influencing regional climatic conditions, affecting the ecosystem and the living organisms in numerous ways. Animal species are able to only survive within specified ranges of climatic as well as environmental factors and incase the conditions changes beyond their tolerance then the animals are likely to exhibit ecological reactions to such changes. Variations in an animal’s behavior like breeding as well as migration occur worldwide and are associated with global climatic changes. Variations in animal spatial distribution especially towards the earth’s poles are taking place as suitable habitats are disappearing. This is greatly affecting the number of animals with some dying because of the incapability of adopting to frequent climate changes (Haldar 26). 

  • If warming continues
  1. Floods and droughts

Higher temperatures may results in the increase in the quantity of moisture evaporating from the land and water surfaces which can lead to drought. Lands that have been affected by drought are more susceptible to flooding during the rainy seasons. As temperature increases throughout the world, droughts are likely to be more frequent and more serious with a probability of devastating impacts on agricultural activities, water supply as well as human health. This occurrence has already been observed in some regions of Asia as well as Africa where longer droughts periods have been experienced (Pilkey 21).

  • Diseases

Global warming is interfering with the natural ecosystem such that it is making life conducive for infectious diseases. Global warming is considered to be one of the major contributors of spread of avian malaria and the spread of insect borne pathogens. Global warming is permitting the bacteria that cause diseases, viruses and fungi to spread into new regions where they are likely to harm various species (Pilkey 33). 

  • Ecosystems

The probability of the ecosystem adjusting naturally is decreasing as a result of the continuous rise of global warming. Various parts of the ecosystem are being affected. Continuous warming can greatly impact the aquatic species. Some water bodies may get too warm for the aquatic animals. Increased warming can also affect the chemical composition of the water and as a result leading to a decline in the quantity of oxygen in water. This may result in the increase in pollution and salinity levels (Coon Para 6).

  1. The Current Political Climate
  1. President Obama’s outlook on Global Warming

President Obama believes that no climate change poses a major threat to the future generations. He therefore issued a direct rebuke to those denying climate change and to the congress members that were seeking to stop the actions of slowing global warming. President Obama stressed on reduction on oil dependence. He urges the implementation of environmental policies that controls some of the human activities influencing global warming, as a way of slowing down global warming (DiStasio Para 6).

  • Current Legislation
  • Global Warming pollution reduction Act

This Act is mainly based on enhancing scientific evidences that global warming is posing a great threat to the national security and the US economy, to the citizen’s health and wellbeing as well as the global environment and that actions should be taken as soon as possible to commence the procedures of minimizing emissions substantially over the next 50 years. The bill outlines the targets, requirements as well as some of the incentives that will be useful in the reduction of emissions and assist in stabilizing the global atmospheric concentration of greenhouse gases (Hufbauer 24).

  • Clean Energy of American and Security Act

This Act contains 5 different tittles including clean energy, energy efficieny, reduction of global warmng pollution, transitioning to a clean energy economy as well as agricultural and forestry related issues. In relation to global warming this act is aimed at mainly reducing global warming pollution (Hufbauer 24).

  • National Fuel Efficiency Policy

This policy is mainly aimed at ensuring strong fuel efficiency and the utilization of the heavy duty trucks for the purpose of benefiting the US economy. It is also aimed at bolstering the nation’s security as well as ensures the reduction of harmful carbon pollutions (Hufbauer 24).

Conclusion

  1. Man-made

The man made factor of the greenhouse effect is as a result of human activities that leads to the emission of greenhouse gases. One of the major activities includes burning of Fossil fuels. Others include changes in land use practices such as deforestation also contributes to the increase in the atmospheric CO2.

  • Obligation

To slow down global warming, it is significant for human to control the rates at which fossil fuels are burnt and opt for other alternative sources of energy such as the utilization of natural energy. Global warming can be stopped with sensible actions that can give way cleaner, and healthier environment.
