Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. Within the next fifty to one hundred years, the earth may be hotter than it has been in the past million years. Global warming will affect weather everywhere, plants and animals everywhere, people everywhere humans are warming the earth's atmosphere by burning fuels, cutting down forest, and by taking part in other activities that release certain heat trapping gases into the air. Fossil fuels like coal, oil, and natural gas that were formed from the remains of plant material deposited during the earth's carboniferous period.

We have known for only a few thousand years that coal, oil, and natural gas can be burned to provide energy. It was not until the mid 1800s, however, that we began to burn very large quantities of these fossil fuels. As this carbon dioxide from burning fossil fuels enters the atmosphere, some of it is taken up by photosynthesizing plants, and the oceans absorb some. But because we are burning so much fossil fuel at such a rapid rate, we are putting carbon dioxide into the atmosphere much faster than these natural processes are taking it out. There is no longer a balance between the amount of carbon dioxide being added to the air and the amount of carbon dioxide being removed. As a result, the concentration of carbon dioxide in the air is steadily increasing. global warming essay, global warming composition writing, essay 1: global warming and what you can do to help.

We hear the term ў°greenhouse gasў± a lotўєbut what is it? humans add various gases to the earthўїs atmosphere every day these gases known as ў°greenhouse gasesў± consist primarily of carbon dioxide, ozone, chlorofluorocarbons, nitrous oxide, and methane, and tend to warm the earth. Trees help counter greenhouse gas production during photosynthesis, by taking in carbon dioxide as waste material and producing oxygen, which of course we all need to survive. Scientists predict that the daily addition of greenhouse gases to the atmosphere, combined with daily removal of large portions of the worldўїs forests, will raise the earthўїs average temperature by several degrees in the next century. This in turn will raise the level of the sea and potentially create significant changes in weather patterns on a global scale.

As we move into the future, many climatologists expect that most of the united states will warm. What we do not know yet is how to scientifically predict which parts of the nation will become wetter or drier. We do know there is likely to be an overall trend toward increased precipitation and evaporation, and more intense weather systems, in the form of violent rainstorms, blizzards and sun baked, drier soils. the factsўєwhat do we already know about changing global conditions global warming ? global temperatures are rising.

Observations collected over the last century suggest that the average land surface temperature has risen 0.45 0.6ўгc 0.8 1.0ўгf in the last century. Precipitation has increased by about 1 percent over the world's continents in the last century, with more rain in high latitudes and less rain in many tropical areas. Sea levels have risen approximately 15 20 cm 6 8 inches worldwide in the last century, due to melting mountain glaciers and ocean expansion from warmer ocean temperatures. Rising global temperatures are expected to further raise sea level, and change precipitation and other local climate conditions. In the next century, the projected 2ўгc 3.6ўгf warming could shift the ideal range of many north american forest tree species by about 300 km 200 mi. climate change could change grazing activities on western rangeland habitats due to shifts in water availability and plant compositions. There will be increases in vector borne diseases such as plague, malaria, encephalitis, and yellow fever.

Loss of habitat may affect populations of many types of wildlife, including birds, reptiles, mammals, fish and sea life. Agricultural crops could be affected in a variety of ways due to changes in rainfall and temperatures. Farming and ranching will require adaptation to new crops or new agricultural practices in the face of climate change. Insulate your home, tune up your furnace, and install energy efficient showerheads. Some dastardly scientists with environmental and political motives manipulated long term scientific data back in the late 1990's to create an allusion of rapid global w arming. Other scientists of the same environmental wacko type jumped into the circle to support and broaden the research to further enhance the totally slanted, bogus global warming claims. Their friends in government steered huge research grants their way to keep the movement going.

Environmental extremist, notable politicians among them then teamed up with movie, media and other liberal, environmental ist journalists to create this wild scientific scenario of the civilization threatening environmental consequences from global warming unless we adhere to their radical agenda. Now their ridicules manipulated science has been accepted as fact and become a cornerstone issue for cnn, cbs, nbc, the democratic political party, the governor of california, school teachers and, in many cases, well informed but very gullible environmental conscientious citizens. Only one reporter at abc has been allowed to counter the global warming frenzy with one 15 minutes documentary segment.
