The Greenhouse Effect
While some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls and strikes the objects inside- plants, flowerpots, tables, and so forth. These objects absorb energy from sun, become warmer, and then give off energy themselves in the form of heat. Only a little of this heat energy passes out through the glass, much of it is "trapped" in the greenhouse, raising the temperature inside. In some ways, the earth functions rather like a greenhouse except on a much larger scale.Although the greenhouse effect has only recently been in the news, is nothing new in th history of our planet, has played major role in making life on earth possible. Without the greenhouse effect, the earth would be too cold for living
In recent decades there has been a global increase in atmospheric carbon dioxide, largely as a result of the burning of fossil fuels. The greenhouse effect may be the most serious environmental problem the human race has ever experienced, for this reason scientists around the world are working hard to acheive a better understanding of the greenhouse effect, to predict the impact it will have on earth, and to discover ways to control it. Global warming can be expected to change the earth's climate dramatically and in a relatively short time. The financial problem with this is that the flooding will cause dams to be built and cities to be reconstructed. If we do not act now, it may be too late. "The amount of carbon dioxide in the atmosphere is increased by 0. Is soemthing good turning bad?" Up until about 150 years ago the compostion of the earths atmosphere had remianed relatively unchanged for several thousand years. Global warming could change the atmosphere so much and so fast that all sorts of plants and animals might soon be in danger os extinction. If this rise in sea level was to occur many areas would be much more prone to flooding, and generally much deeper floods would be experienced than nowadays. Right now it is moving so that North America is going to be close to the sun in the winter. The Cretaceous Period occurred over 100 million years ago. While going through this cycle it will change the climate of areas. Overall, the global temperature could rise anywhere from 5 to 9 degrees over the next fifty years. What is meant by the term, the greenhouse effect, is that the heat from the sun comes into the Earth's atmosphere and cannot get out so it becomes trapped.
