.... be relied on until it covers more land. Also, I find it difficult to argue with two different sources that prove each other's information to be accurate. I do not, however, feel that we should immediately depend on the reliability of either conjecture since the stakes are so high. I feel that further research and development should be pursued.
I think that electric cars should be exposed into the consumer market. Also, we as a nation should enforce environmental laws on third world country industr .....

Even if we change our practices in time to avoid these climatic disturbances, the environment will still have an effected and this is including all the ecological history. The environment may initially shape the range of choices available to a people at a given moment, but then culture reshapes environment in responding to those choices.
There are many possible adverse side effects of global warming on living and nonliving systems. For example, certain type .....

- Satellite data indicate a slight cooling in the climate in the last 18 years. These satellites use advanced technology and are not subject to the "heat island" effect around major cities that alters ground-based thermometers.
- Projections of future climate changes are uncertain. Although some computer models predict warming in the next century, these models are very limited. The effects of cloud formations, precipitation, the role of the oce .....

Global Warming 2
.... 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the heat-trapping worse in the earth's atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space, but, sulfates do not live long in the atmosphere.
Why are greenhouse gas concentrations increasing? Most scientists believe that the burning of fossil fuels and other human's doings is the main reason for the incr .....

.... began to alter the composition of the atmosphere. Vast supplies of charcoal, and later coal and oil, fed the growing fires of the Industrial Revolution. The carbon stored in these fuels was released to the air as carbon dioxide - a gas that traps heat in the atmosphere. Today, for every one of the more than 5.8 billion people on Earth, nearly six tons of carbon dioxide is spewed into the air every year. As a result of our activities, the gas trapped inside the atmosphere has risen by more than 30 perce .....

.... gases include carbon dioxide, methane, nitrous oxide, and ozone
depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the
use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests.
These human practices have already changed the chemical make up of the atmosphere. .....

Global Warming 3
.... Our atmosphere, which is made up of four distinct layers blankets our planet and protects up in many way. One way it protects us if from the harmful rays the sun radiates on our planet. Each layer differs from the others in temperature, density, composition and in the way it absorbs radiation from the sun. The atmosphere itself is some 300 miles thick. The first layer is the Troposphere. It is the lowest layer and extends higher than any airplane can travel, about 6.8 miles. Air in this layer is h .....

.... prelude to global warming, the decade of the 1980’s has had the six hottest years of the century (Erandson 18-22). Atmospheric disturbances brought on by the additional warming will produce more violent storms and larger death tolls. Some areas, particularly in the Northern Hemisphere, will dry out and a greater occurrence of lightning strikes will set massive forest fires. The charring of the Earth by natural and man-made forest fires will dump additional quantities of carbon dioxide into the atmos .....

FIRST of all, it is important to know that the "greenhouse effect" is not a bad thing in itself. In fact, this planet would be a life-less waste land without its natural greenhouseing. There are a collection of gases called "greenhouse gases," which are water vapor, carbine dioxide, ozone, methane, nitrous oxide, and chlorofluorocarbons (CFC). Without the natural greenhouse effect, the surface temperature of our planet would be an average of -18°C (zero degrees F). The mixture of .....

million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Global warming will effect weather everywhere, plants and animals ever .....

Because their cardiovascular system has to work harder to keep the body cool during hot weather. The temperature causes harmful effects to human health and another is cause of lung problem. "Higher air temperatures also increases the concentration of ozone at ground level". When this happens, the harmful u .....

Global Warming And The Greenhouse Effect

The increases of these chemicals have enhanced the heat trapping capability of the atmosphere of the earth. Sulfate aerosols, cool the atmosphere because they reflect light back into space, but sulfates do not live long in the atmosphere.
Scientists still do not know what exactly is heating up the earth. Some say the earth is .....

The National Weather Service announced that 1998 was the warmest year (on record on average, around the world). A recent tree-ring study indicated that this is the warmest decade in six hundred years (Allen & Herreid, 82). Undeniably, the weather is getting warmer. According to an article in The Economist, a conservative newsmagazine,
"The sea is warming, the plankton dying; floods are sweeping the land. In California, the climate is acting in a peculiar way. So, too, in Antarctica, wh .....

Global Warming--is It Getting Warmer
.... It is then transformed into heat energy at the planet's surface. This heat energy then radiates upward into space. There the greenhouse gases found naturally in the troposphere absorb some of the infrared radiation. The gases insulate the Earth, but do eventually allowing some of the heat to escape. The rest of the heat reflects back down to earth where it is bounced back up again. Almost like an ongoing game of ping-pong. With more of the greenhouse gasses being let out into the atmosphere, there .....

.... is the “noblest” of the noble metals (gold, platinum, palladium, and rhodium), so termed because of their inertness, or reluctance to enter into chemical reactions. Gold will not react with common acids but is attacked by a three-to-one mixture of hydrochloric and nitric acids. This combination is called aqua regia because it reacts with the so-called royal metal. Gold will not combine directly with oxygen, but oxides may be formed indirectly. Gold will also combine with the halogens (fluor .....
