Effects and Causes of Global Warming

By otikokorsuonana Feb 28, 2009 1260 Words
What is Global Warming? Global Warming is defined as the increase of the average temperature on Earth. As the Earth is getting hotter, disasters like hurricanes, droughts and floods are getting more frequent. Over the last 100 years, the average temperature of the air near the Earth´s surface has risen a little less than 1° Celsius (0.74 ± 0.18°C, or 1.3 ± 0.32° Fahrenheit). Does not seem all that much? It is responsible for the conspicuous increase in storms, floods and raging forest fires we have seen in the last ten years, though, say scientists. Their data show that an increase of one degree Celsius makes the Earth warmer now than it has been for at least a thousand years. Out of the 20 warmest years on record, 19 have occurred since 1980. The three hottest years ever observed have all occurred in the last eight years, even. Earth should be in cool-down-period But it is not only about how much the Earth is warming, it is also about how fast it is warming. There have always been natural climate changes – Ice Ages and the warm intermediate times between them – but those evolved over periods of 50,000 to 100,000 years. A temperature rise as fast as the one we have seen over the last 30 years has never happened before, as far as scientists can ascertain. Moreover, normally the Earth should now be in a cool-down-period, according to natural effects like solar cycles and volcano activity, not in a heating-up phase. Global Warming; Cause And Effect Global Warming Have you ever wondered what it would be like to go a whole winter without even seeing snow? Well the way the atmosphere is heating up today you just might experience this kind of event in the future I chose to do my cause and effect paper on global warming because I believe it has a major impact on humans, not only today, but especially in the future. In this paper I am going to explain the causes and the effects of global warming and how it will impact our lives in the long run. Greenhouse gases are gases such as carbon dioxide, methane, nitrous oxide, and ozone, and play an important roll in the earth's atmosphere. Without them it would really be cold, but that does not seem to be the problem in today's life. Over the past sixty years, the world's ozone layer has built up tremendously because of trapped gases being. Because of this build up it does not allow the gases to leave the atmosphere, which is a bad thing for the atmosphere. For example, greenhouse gases are like riding down the road with the windows up and the sun shining through the car windows. The windows allow the light and heat in, but there is no where for it to go after it enters. This causes the inside of the vehicle to heat up. This is basically what is happening to our atmosphere. Our atmosphere is heating up like global warming, which is exactly like the heat being trapped inside of the car. The major effect of global warming is that it is heating up the entire world. Which is not exactly a good thing. Because when the atmosphere heats up so does the Antarctic Ocean. In fact, over half of it is made up of ice burgs and ice. When they heat up, they melt, which causes mass amounts of flooding, yet another effect of global warming and greenhouse gases. Another leading cause of global warming is us, humans. As years go by, more and more land is being cleared off, which is most commonly known as deforestation (Wikipedia). People are... Professor Aida Owens

Factors That Cause Global Warming

How many of us have ever lived in or visited a warm, tropical city? Whenever you were

there, did you enjoy the warm feeling of the sun touching your skin? Chances are we all "soaked

up some rays" at some point in our life and felt good about it. Now imagine the climate always

feeling that good year round. There's nothing wrong with that, is there? So why does the media,

the government, and politicians try to scare us all into believing that global warming is a bad

thing? A good example of the scare tactics used by the media is the fight global warming ads

on television and radio. The government insists that automobile manufacturers need to make

lower emission producing vehicles. As far as politicians, they will say anything just to get your

vote. We hear so much about how we are affecting and changing the climate on Earth. Is this

an assumption or are we really contributing to the rising temperature on Earth? In order to

answer this question, we have to first understand what is global warming.

The easiest way to understand global warming is to compare it to a greenhouse. If

anybody has ever been inside a greenhouse, you know it is very warm inside. The

atmosphere above the earth traps heat in that is put off by the sun. Some of the heat is absorbed

by the earth and the rest of the heat is absorbed back in to space. This is known as the

greenhouse effect. The greenhouse effect is the natural warming of the... The Causes And Effects Of Global Warming THE CAUSES AND EFFECTS OF GLOBAL WARMING This essay is on the causes and effects of global warming. How will this affect the world? Will we be ready for when this happens and how will we prepare for this? All these questions will be answered in this essay. The causes of global warming are said to be the ‘human race’ in general. There are many arguments of what the true causes of global warming really are. The other main cause that is being discussed is all the carbon emissions from all of the factories and manufacturing plants. The reason why we are concerned is because the temperature is supposable changing rapidly. This is said to be the highest temperature we have seen since thousands of years ago. The other thing that is thought to produce the extreme temperature changes is the greenhouse gasses. These are made up of carbon dioxide which is the number one cause for the raise in temperature. Everyone fears the effects of global warming on the earth. The main effects that are feared to happen are the melting of the glaciers and the drying of the rain forest. The melting of the glaciers would raze the ocean so much that it would put five miles from the shore under water. There would be less rainfall in numerous places with the result of the deaths of many crops. Storms would become more frequent. The types of storms would include hurricanes and tornadoes of immense power. The extreme changes in the weather and environment would put a lot of species into extinction. The human race would even have trouble surviving. We will be ready for this when it happens because we are putting a lot of our tax money into finding ways to avoid the effects of global warming and the secrets to stopping it. We are already changing our fuel to ethanol. This is a clean burning fuel and will not contribute to the greenhouse gasses. We are also using more solar panels to use more raw energy rather than taking it straight from the earth....
