    Meghan McDonald McDonald 1 Mr. Hrk al OAC World Issues December 18 th, 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) ris...

    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 ...

    English 101 October 31, 1998 Global Warming Global Warming is an important ecological issue because it has several negative effects upon our environment. Global Warming, or what has been called the Greenhouse effect, is the result of a fourfold ecological process. 1-Sunlight radiates from the sun, through space, to Earth's atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air a...

    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 diox...

    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...

    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...

    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 ...

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. Increasin...

    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 ...

    The process of warmth circulating and the natural greenhouse effect are well balanced. Every change in the concentration of greenhouse gases leads to the aggravation of greenhouse effect which in turn leads to the aggravation of global warming. Global warming is increasing the melt of ice in the Arctic region. Today scientists do not challenge the destructive force of human activity. Now, they are deeply convinced that the slightest change in the ability of Earth to absorb warmth, including the ...

    Greenhouse gases are important in maintaining Earths habitable climate. These greenhouse gases must fall within a narrow range. Too much of any of the greenhouse gases can induce climatic changes, in particular, global warming. Of the greatest concern are the anthropogenic sources of greenhouse gases because they are steadily increasing in concentration in the atmosphere, and therefore increasing the natural ability of the greenhouse effect. As the debate continues on whether or not global warm...

    Humankind is conducting an ongoing experiment to see what will happen to our health and to the well being of the planet when changes in the earth's climate are made. This experiment is called global warming. Global warming is allegedly changing the world, as we know it. The concern of global warming is the increasing temperature of the earth's climate, which is expected to warm even further because of human activities that include the burning of fossil fuels to run cars and trucks, heat homes an...

    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.

    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...

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.

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...
