An Introduction Many researchers, scientists, and environmentalists are expressing concerns about changes in the overall climate of the earth. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as "global warming. Climate is defined as the analysis of accumulated weather data for long term patterns and trends.

The Oxford Reference Dictionary defines change as, "To make or become different. Changes in climate can result from both natural events and human activities. Examples of natural causes of climate change are volcanic eruptions, variations in the earth's orbit around the sun, and variations in solar output Ahrens, 485-491.

Examples of human-induced causes of climate change include industrial pollutants and fossil fuels Rhodes, 116warming of average annual temperatures due to urbanization Eichenlaub, 163and changes in the earth's albedo due introduction of a research paper about global warming deforestation of tropical rainforests Geiger, 320.

Climate change in the context of this paper refers to changes that result from human activities, especially as these changes relate to the issue of global warming. Of special importance is the "greenhouse gas" effect which is defined as, "The trapping of thermal emissions from the earth's surface by human-induced greenhouse gases" He.

If global warming is indeed happening, it is the greenhouse gas effect that is believed to be the most responsible. There are some scientists who do not believe that there is enough evidence to support the idea of global warming. They assert that concerns about global warming have been blown well out of proportion by the media. At the same time, other scientists assert that there is sufficient evidence to suggest that industrial activities, automobile emissions, and technological pollutants may eventually result in dangerous and even deadly trends in the overall global climate.

This paper will attempt to address this concern by analyzing some of the scientific studies that have been published in major meteorology journals. Our atmosphere consists of many gases.

Climate Change and Global Warming Introduction

Some of these gases, such as carbon dioxide and water vapor, naturally absorb long-wave radiation that is emitted from the earth's surface. This radiation is then recycled and emitted as long wave terrestrial radiation.

Gases such as water vapor and carbon dioxide absorb this radiation, hold it in the atmosphere, and keep the temperature of the earth warmer than it would otherwise be if there wasn't an atmosphere. This is what meteorologists refer to as the "natural greenhouse effect" Mower. Problems could potentially arise, however, when human activities add additional trace gases into the atmosphere that also absorb out-going long-wave radiation. These additional trace gases include methane, chlorofloro carbons, nitrous oxide, aerosols, ozone, and carbon dioxide.

The result is an increase in the amount of long-wave radiation that is being trapped by the atmosphere. It is believed that this could eventually increase the average overall global temperature. It is clear from looking at the evidence that carbon dioxide concentrations are increasing dramatically in the atmosphere.

Observations of carbon dioxide concentrations are available for several locations. Over the period of 1973 to 1982, the atmospheric concentrations of carbon dioxide in Barrow, Alaska rose steadily from 332.

This is not isolated to Barrow, Alaska. Records from other locations, such as Mauna Loa in Hawaii, are confirming that carbon dioxide concentrations are increasing in the atmosphere introduction of a research paper about global warming a dramatic rate.

Continuous instrument records for atmospheric carbon dioxide concentrations date back to the 1950's at the Mauna Loa observatory Michaels, 1564.

In 1958, the average atmospheric concentration of carbon dioxide was only 316 parts per million ppm. Preindustrial carbon dioxide concentrations are believed to be 279 parts per million Michaels, 1564and the atmospheric carbon dioxide concentration in 1990 was 353 parts per million Rhodes, 116.

However, as one author points out, the fact that we are dealing with significant changes in carbon dioxide does not automatically mean that we are looking at a serious problem Lindzen, 288. This author points out that carbon dioxide is a ".

Increasing carbon dioxide should cool these regions, and this, in turn, should lead to increasing concentrations of ozone at these levels.

Writing An Introduction For A Research Paper On Global Warming

Increasing carbon dioxide might also stimulate the growth of vegetation. While there are indeed some possible benefits to increased atmospheric carbon dioxide concentrations, ". One author wrote that there is ".

There are studies that have indicated that no significant change in the overall global climate has yet taken place. For example, a study that was done by P. Other studies showed that the Northern Hemisphere has had no significant warming, while the Southern Hemisphere has had a slight temperature increase in the order of 0. Michaels speculates that the reason that we have not seen a significant increase in temperatures in the Northern Hemisphere is because of the balancing effect of anthropogenerated sulfates going into the atmosphere as a result of industrial pollution.

Anthropogenerated sulfates have a cooling effect on the atmosphere because of their ability to reflect incoming solar radiation back to space.

Michaels explains this in more detail when he writes, "Because anthropogenerated sulfates are primarily produced and reside in the Northern Hemisphere, we may therefore be equaling the current enhanced greenhouse forcing.

  1. Increasing carbon dioxide should cool these regions, and this, in turn, should lead to increasing concentrations of ozone at these levels. Instead of being defined by moisture content, overlying snow cover, or location, permafrost is defined and characterized by temperature.
  2. Reasons vary from lacking resources to cope, compared to developed nations, immense poverty, regions that many developing countries are in happen to be the ones where severe weather will hit the most, small island nations area already seeing sea level rising, and so on. Solutions for the problems to home foundations include.
  3. The production and global distribution of manufactured products thus form a large portion of global human carbon emissions.
  4. Construction and maintenance of the infrastructure in the Arctic depends upon the climate. Volume 74, Number 4 April 1991 , pp.

This lead to the obvious question of whether or not the lack of a significant increase in global temperature should be taken as evidence that we should not be concerned about the issue.

Kellog points out that ". The global average surface temperature would probably rise by about 2 to 5 K if the greenhouse gas concentration were maintained at double the pre-industrial revolution level" Kellog, 500. Kellog suggests that the reason that we have not seen a change as of yet in the overall warming is because of a temperature lag of several decades ". He asserts that the evidence is still in favor of the fact that, sooner or later, a serious warming of the climate will occur.
