As the Defense Council states, global warming is caused by carbon dioxide and other types of heat trapping pollution that are collecting like a blanket in the atmosphere, trapping heat from the earth as it tries to radiate back into space. As a result, the planet is getting warming. In fact, 2002 was the hottest year yet. In an article in World Almanac and Book of Facts, 9 out of the10 hottest years have been in the 90's. There are a few major causes of theses heat trapping gases.

Global Warming and The Environment Global warming is a term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans (All About Global Warming, 2007, para.1). There is no doubt this is an important matter that will impact planet earth for many years to come. Global warming is a critical issue that impacts the entire world and the potential consequences caused by it will have a negative impact if human contribution is not reduced. Although many people disagree with the causes and outcomes, there is certainly enough information available to support the argument. At this time, global warming is said to be a crisis with carbon and emissions of Co2 being made out to be the culprit (Turpin, 2007, p.30).
“The most plentiful human-generated greenhouse gas is carbon dioxide, released by the burning of fossil fuels.”(Global Warming 2001). The growth in population and mass industrialization have put Mother Nature to her knees, begging for the cooperation of human kind and nature to compromise a fair balance of existence. If global warming continues “Planet earth will turn into our sister planet Venus and temperatures will rise to 250 degrees. We are killing it for future generations to come, and eventually it will be too late for anything to be done. We are leaders that are misleading” (11th hour).

Global warming is caused when carbon dioxide and other temperature trapping emissions are discharged into atmosphere, and they perform a similar function to a blanket, letting in light but retaining heat in our atmosphere that would otherwise dissipate, resulting in an increase in temperature. This is known to as the greenhouse effect as it is so similar to the function of glass walls in a greenhouse. The first thing that happens is sunlight shines onto the Earth's surface, where it is soaked up and later releases back into the atmosphere as heat. This is hindered by the previously mentioned “greenhouse” gases, some of this heat escapes, and some of it is trapped in the atmosphere; the more greenhouse gas that is in the atmosphere, the more heat that is trapped. The greenhouse effect in its natural form is a good thing, as without it the earth would be sitting at zero degrees Fahrenheit, rather than the current fifty-seven degrees Fahrenheit.
More importantly, an article titled "Global Warming" published in the New York Times shows that methane, a gas that is emitted from landfills, livestock and oil gas facilities, is a close second to the carbon dioxide impact on the atmosphere (“Global Warming”). Though there are many scientists who support and can prove that global warming really does exist, a team of scientists from Competitive Enterprise Institute (CEI) spend their time and energy disproving the myths behind global warming. According to the CEI website, CEI is a company that specializes in debunking those who warn about global warming and climate change (Competitive Enterprise Institute). CEI was founded in 1984 by a group of scientists who all wanted to answer the same question: is global warming real or is it a myth? A compelling argument is presented by the scientists who work for CEI who believe that global warming is a bunch of nonsense that the government wants the public to believe.
When solar radiation enters the earth’s atmosphere some of the energy is absorbed by the earth, while the rest is refracted back into space. During this process, when radiation emits from the surface back into the atmosphere, greenhouse gases such as water vapor, Carbon Dioxide (CO2), and Methane trap some of the radiating heat in our atmosphere and cause the surface of the earth to warm up. This is a natural process that has occurred on earth even before the existence of humans, and still naturally occurs today. Moreover, clouds, or large masses of water vapor, are natural absorbers and refractors of energy. Although they reflect more solar energy than they absorb, they still help to maintain a warm and tolerable planet for all living kind, thus clouds play a big part in the warmin... ... middle of paper ... ...on the facts presented, it is up to you to decide which theory you believe in.
The process of global warming is that the earth is getting heated by the sun but not all the radiation is released back into space. Majority of the radiation is absorbed in the greenhouse gases. This lets the earth get more heat and it absorbs the energy. The earth will repeat this cycle over and over again. The major greenhouse gases are carbon dioxide.
