The paper illustrates the environmental phenomenon called Global Warming. It throws light on the controversy surrounding it and the facts which ascertain its existence. The paper also discusses the causes and disturbing consequences of Global Warming, which have been proved through statistics and data…
This climate change is believed to have dramatic effects on several atmospheric events. Studies conducted by the Intergovernmental Panel on Climate Change (IPCC) (2007) conclude that the mean global temperature near the earth's surface experienced an increase of 0.74 + 0.18 degrees Celsius during a period of 100 years from 1905 to 2005. The IPCC has also projected that he global temperature will experience a further increase of 1.1 to 6.4 degrees Celsius through the twenty-first century. (2007) Owing to the rather obscure nature of changes taking place in the atmosphere, this phenomenon remains surrounded by controversy. A portion of the masses refuses to accept the magnitude of global warming and proclaim that the phenomenon is caused by completely natural sources like solar variations and volcanic eruptions. But some very alarming facts stated later will assure everyone of the damaging implications global warming has had on our planet.
The IPCC blames the human race for a major part of global warming, " most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic (man-made) greenhouse gas concentrations"
Greenhouse gases are the gases presnt in the atmosphere even under normal conditions. These gases, which include (in order of their abundance) water vapour, carbon-di-oxide, methane, nitrous oxide, ozone and CFC's, are essential to bring about the Greenhouse effect. These gases capture the infrared radiations from the sun's emission and retain it, thus warming the earth's atmosphere. If it wasn't for the greenhouse effect, the earth's temperature would have been close to -19 degrees Celsius. But, in the recent times, excess of these greenhouse gases has enhanced the greenhouse effect, which has lead to excessive warming of the planet. Human activities like the industrial revolution, fossil fuel burning and deforestation have resulted in a dramatic rise in the concentration of these gases. The level of CO2, which was constant at 280 ppm for nearly 800 years till 1800 has suddenly risen to 378 ppm in 2000. (Hadley Centre, 2005)
Effects of Global Warming
As mentioned earlier, the mean global temperature of the earth has increased during the past years. IPCC's reports say that 11 of the past 12 years are among the twelve hottest years since 1800. (2007) Studies conducted by NASA Goddard Institute of Space Studies declared 2005 to be the warmest year ever, even surpassing 1988, which was unusually warm because of the strongest El Nino (2006).
The temperature records of the rural and urban areas of the United States Of America (IPCC, 2007) only vindicate that fact. The temperatures have recorded a constant increase. Studies conducted by the US Public Research Interest Group, the average temperature of Washington DC was 3 degrees F above normal.
The retreat and disappearance of glaciers has accelerated at an alarming rate since 1980. According to Munich Re, the total surface area occupied by glaciers worldwide has decreased by nearly 50% (2007). Satellite pictures of the Greenland Glaciers show that they have retreated ...

The purpose of this research is to attempt to get the scientific community to agree that global warming related variables can be combated more efficiently with better cooperation. Take politics, economics, greed, and self interests of various governments out of the debate and merely focus on the facts, and labeling the problem whatever you desire, can and will support worldwide comprehensive improvements.
The natural system consists of air (atmosphere), water (hydrosphere), rocks (lithosphere) and living things including our selves (biosphere). This essay will focus the atmosphere and biosphere that how the activities of human beings affect the atmosphere and how these activities can be stopped.
In small firms, the same advantages are realized except that management must be aware of the sentiments of old personnel in rehiring a previous colleague. The disadvantages of rehiring a previous employee in large and small firms are potential displacement of the personnel who assumed the position (especially in large firms); and addressing the perceptions and sentiments of current and loyal personnel (particularly in small firms).
Global warming has been one of the most debated topics in the past few decades. The term ‘global warming’ is used for the gradual increase in the average temperature of Earth’s atmosphere. Increase in the average temperature of Earth’s atmosphere has been observed since in the late 19th century and the marginal increase has been rising in the recent past.
Global warming has been one of the most important topics of discussion in scientific and policy circles for decades now. Despite relative scientific consensus on the fact that global warming is happening, there are still many logjams towards actually getting anything done on the topic. The effects of climate change are poorly understood.
Generally, greenhouse gases that collect in the atmosphere get the blame for global warming, since this supposedly triggers climate change that in turn leads to such ecological aberrations as ozone layer depletion, rising sea levels and changes in the pattern and amount of precipitation.
Global warming can be traced to the increased level of greenhouse gases like carbon dioxide in the atmosphere because of human activity such as coal burning and the use of automobiles (Global Warming Basics 2).
This rise in temperature is expected to bring about sudden changes in the global climate "causing parts of the earth to dramatically heat up or cool down in a span of few years" (Global Warming 1).
During the last century, the average temperature has risen from 0.74 -0.18oC. It has caused many side effects, which include, rise in sea level and strong changes in the form of rainfall contributing to floods and drought. The melting of the Polar ice caps has resulted in higher and warmer sea levels.
The rapid industrialization that has occurred in the past few centuries is the fundamental cause of increase in global warming. Air pollution is the basic cause of global warming. The air has been enormously polluted by the smoke escaping from
ming has also made an impact on the constant rise in sea levels, meltdown of ice caps on mountains and had thus caused huge changes in global climatic conditions (Vitousek, pp. 1861-1876). In my point of view, global warming does not only represent a change in climatic
