For the past ten thousand years the earth's climate has been extremely good and beneficial to mankind. Today however , major changes are taking place. Humans beings are changing the face of the entire planet by destroying the rain forests and pumping our pollutants into the air and water. Some of these gases are very toxic and they are destroying our ozone layers which allows life to exist on earth These things are changing the make-up of the earth's biosphere and its heat balance in a very negative way.
Global Warming is an increase in the earth's temperature due to the use of fossil fuels and other industrial processes, leading to a buildup of green house gasses. It has been known that using these gasses stops the suns heat rays from getting into space.
This is called the green house effect. There is a question weather this adds to Co2 levels in the atmosphere. A rise in temperature could cause coastal folding and major climatic changes. This could have serious effects on agricultural productivity. Since 1850 there has been an average rise of 1 degree calculus (1.8 Fahrenheit). But this rise could be just a natural fluctuation or it could be from humans pumping fossil fuels into the atmosphere. It can be hard to tell if it is natural or man made, but either way, in 1995 it was the hottest year on record, research shows from the British Meteorological office. Some scientists predict that if green house gasses are not reduced quickly, temperatures could raise the average temperature 1.8 to 6.3 degree Fahrenheit by 2100. The average temperature rose 1.8-degree Fahrenheit from 1850 to about 1998. This says the temperature is rising faster because of more fossil fuels and Co2 being pumped into the atmosphere. These increases of temperature, scientists predict, could cause sea levels to rise 20 inches and more. Many of the world's greatest scientist's say the potential consequences are so great that many are urging immediate action, and are asking for international cooperation.
Climate Change has caused some extreme and weather breaking events in recent years. There have been heat waves in European and North America, floods in Africa after nearly 2 decades of drought, and nearly continuous rain and cold in the middle of summer at other places. In the 80`s six of the hottest years of the century were recorded. This could be a result of a global climate change caused by the chemical pollution of the atmosphere. As of yet, no sign of climate change has happened yet that can be blamed on the green house effect.
The Greenhouse Effect is the roll that the atmosphere plays in insulating and warming the earth's surface. The atmosphere is the part of the earth that is covered by a thin blanket of gasses. Nitrogen and oxygen are the main gasses in our atmosphere. We would not be able to survive without oxygen. When the sunlight hits the earth it turns to heat or infrared energy. Some of this heat energy is absorbed by soils, plants, and water on the earth's surfaced. A lot of this is reflected back toward space, but not all. Carbon dioxide and other similar gasses absorb this heat, and prevent it from going back to space. Carbon dioxide absorbs this heat and warms the atmosphere. It is like a window in a car on a summer day. The glass lets in sunlight but keeps the heat from escaping, like a glass or plastic window in a greenhouse traps heat and protects plants from the cold. This is the greenhouse effect.
The Carbon Cycle is a natural process of carbon dioxide entering the air. It is present in some kinds of rocks and in coral reefs. Large amounts are also stored for a time in soils, in ocean waters, and in sediments at the bottom of the oceans. It is released by erosion, plants and from decaying things. The scientists learn about the earth's atmosphere and past by studying...
