  • Increase Of Greenhouse Gases
    1,720 words
    Global Warming: "It's gett in' hot in here, so take off all your clothes... ". The famous words of R&B star, Nelly, are truer than one might think. It really is getting hot in here. The world's average temperature is rising every year and is expected to be 5 to 10 degrees higher by the end of the century, which is faster than they have increased in the last ten millennia, according to the National Resource Defense Council's website. But why is this epidemic happening? As the Defense Council stat...

    2,000 words
    Meghan McDonald McDonald 1 Mr. Hrk al OAC World Issues December 18th, 2000 Global Warming Now, for the first time in Earth's history, humans may be a decisive factor in future climate change. The actions we make towards the temperature of the earth and the depletion of the ozone layer are irreversible. A warmer future could result from present-day human activities releasing large amounts of heat-trapping gases into the air. These "greenhouse gases" are part of the reason for the 1 F (. 5 C) rise...
  • Known As Greenhouse Gases
    1,261 words
    The Greenhouse Effect The United States releases twenty tons of carbon monoxide per person per year. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment. Every day fuel is burnt by cars, airplanes, large factories and manufacturing plants. This is causing a very large and deadly problem for our environment. When gases used on earth are released into the atmosphere they act as ...
  • Its Greenhouse Gas Emissions
    414 words
    What is global warming? Scientists have discovered that concentrations of minor greenhouse gases in the atmosphere, particularly carbon dioxide are rising. Theoretically, these gases could trap more heat in the atmosphere, leading to a gradual warming of the Earth's atmosphere. And, again theoretically, global warming could be harmful to the environment and to human health. The treaty, called the Kyoto Protocol, would require the U.S. to reduce its greenhouse gas emissions primarily carbon dioxi...
  • Chlorine In The Atmosphere The Ozone Hole
    965 words
    The Greenhouse Effect The earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Energy from the sun drives the earth's weather and climate, and heats the earth's surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour, carbon dioxide, and other gases) trap some of the outgoing en...
  • Harmful Gases Into The Earth's Atmosphere
    1,814 words
    INTRODUCTION In the beginning man lived simply and harmoniously with earth. However, as time progressed mankind's thirst for knowledge and more economical ways of doing things led to technological advances. These advances, in turn, led to the industrial revolution, the invention of the automobile, and growth of the automobile industry. Though making life on earth more comfortable, these industries and inventions emitted harmful gases into the earth's atmosphere. Damage to the earth's ozone layer...
  • Upper Levels Of The Earth Aeurtms Atmosphere
    376 words
    Human induced climate change resulting from an enhanced greenhouse effect is probably the greatest environmental threat facing the world today. Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earth^aEURTMs atmosphere, it diminishes or breaks down the earths^aEURTM Ozone layer. With this loss of this protective blanket, harmful radioactive rays from the sun enter the de...
  • Increase In Greenhouse Gases
    1,737 words
    Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad. By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of ...
  • Average Global Surface Temperature
    1,447 words
    AN INTRODUCTION According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. Th...
  • Levels Of Greenhouse Gases In The Atmosphere
    1,287 words
    Dwyer 1 Jeffery D. Dwyer The causes and effects of Global Warming. Like many pioneer fields of study, there are uncertainties associated with the science of global warming. This does not imply that all things are equally uncertain. Some aspects of the science are based on well-known physical laws and documented trends, while other aspects range from 'near certainty' to 'big unknowns'. Scientists know for certain that human activities are changing the composition of Earth's atmosphere. Increasing...
  • Atmosphere By The Greenhouse Gases
    331 words
    THE GREENHOUSE EFFECT The greenhouse effect: retention of heat in the Earth's atmosphere due to the presence of greenhouse gases. In this essay, I will tell you how the greenhouse effect works and the importance it has in our atmosphere and everyday life. The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane) trap energy from the sun. Without these certain gases, the heat would ...
  • Fossil Fuels Causes Carbon Dioxide Pollution
    2,022 words
    For years, scientists have warned that pollution from burning fossil fuels would cause dangerous warming of the planet. The hottest 10 years on record have all occurred since 1980.1998 was the hottest year ever recorded. With scientists predicting more violent weather, spread of infectious diseases, and rising sea levels. According to Accu-Weather, the worlds leading commercial forecaster, Global air temperatures as measured by land-based weather stations show an increase of about 0.45 degrees C...
  • Greenhouse Gases In The Earth's Atmosphere
    1,029 words
    "The snow-capped mountains and glaciers are disappearing, coral reefs and the rich, colorful variety of life they support are dying as we watch. Entire ecosystems are breaking up as individual species struggle to adapt, some less successfully than others". The heat is on...

Governments and scientists alike have agreed that the problem is...
  • Carbon Dioxide Emissions From Federal Vehicles
    1,463 words
    Now more than ever humans are becoming a major factor in the future of climate and more importantly climate change. Human actions towards the earth and the depletion of the ozone layer are irreversible. A warmer future could result from human activities in the present by releasing massive amounts of heat trapping gases into the air. (web) These greenhouse gases are partially the reason for the 0.5^0 C rise in the global average temperature recorded over the past 100 years. If the Earth's tempera...
  • Greenhouse Gases To The Atmosphere
    825 words
    Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is about global warming caused by human activities. An examination of surface temperature records shows there has been a gradual increase in average temperatures around the worl...
  • Cent Of The World's Greenhouse Gases
    633 words
    SCIENCE RESEARCH PROJECT ALL COUNTRIES SHOULD REDUCE GREENHOUSE EMISSIONS. Without the greenhouse effect the Earth would not be warm enough for humans to live, but if it becomes even a little warmer there will be major problems. The greenhouse effect is the rise in temperature the Earth experiences because certain gases in the atmosphere (water vapour, carbon dioxide, nitrous and methane, for example) trap energy from the sun, forming greenhouse-like layer. Average global temperatures have incre...
  • Wide Emissions Of Green House Gases
    1,618 words
    Global Warming Long ago the earth was conceived in a fiery blast of volcanoes and molten lava. The earth cooled and life was spawned. From the first bacterium that swam in a new ocean thru just before the industrial revolution climate, lacking any external factors, has steadily changed. But since the industrialization of civilization, the climate of the earth has faced an ever growing foreign factor. This factor is the emissions of the so called "greenhouse gases" that have caused the rapid incr...
