IntroductionGlobal Warming, aside from pollution is one of the biggest scientist's concerns. Global Warming is the term used to describe increase in the temperature of the Earth. It is the process, which is continuously warming the earth. The Earth's surface temperature has risen by about one degree Fahrenheit in the past century, with accelerated warming during the past three decades. There is stronger evidence and proof that most of the warming over the last fifty years is attributable to activities of human. Human activities have changed the chemical composition of the atmosphere and environment through the buildup of greenhouse gases, which are main cause of Global Warming.There are four steps in the Greenhouse effect, which are, Ultraviolet rays from the sun, through space, to earth's atmosphere. The sunlight enters the atmosphere and hits Earth. Some of sunlight turns into heat energy in the form of infrared light. The heat gets impregnated by enclosing air and land, which in turn makes it hot. Infrared rays that are remitted into the atmosphere are captured by greenhouse gases. The gas then absorbs the light and is sent back to the surface of Earth and warms it even more.According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases - primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth's climate responds to them. (Lubchenko 1998)EPA Global Warming: ClimateMethane and carbon dioxide are some of the naturally occurring greenhouse gases. This is the manner in which the Earth keeps itself temperate enough for humans to live on it. The only concern with this is that humans are enhancing the process even further and it will result in Global Warming. Over the past many years the emissions of greenhouse gases have been multiplying due to the rapid growth in technology that humans have perfected like, factories which are emitting such dangerous gases which includes methane, carbon dioxide, nitrous oxide, and ozone depleting substances such as CFCs, also known as Hydro-fluorocarbons, Chlorofluorocarbons, and Per-fluorocarbons.Basically global warming is the ascent of the earth's surface temperature due to chemicals in the atmosphere. The threats that global warming brings along with it includes: affecting the climate of the Earth and even the health of the people. This also includes altering of crop seasons. Global warming also affects the way organisms survive on the planet.Signs and EffectsA large amount of the United States is probable to warm, even though sulfates possibly will...

You ask - what does the greenhouse effect have to do with global warming? When humans release gases into the air, the greenhouse effect will alter the temperature of the earth. More gases in the atmosphere means the earth will start to get warmer, and the result is global warming. On
