Global Warming 1Important Facts about the increasing problem of Global WarmingSandra PerezAxia Collage University of PhoenixGlobal Warming 2Global Warming is a change temperature of the Earth. This is a problem that is an original process of Mother Nature; however, has been altered or speeds with the help of human behavior. The consequences of this problem have already been seen and will continue to intensify if something does not get done to slow it down or stop this process. If we do not take this serious, the result will be the extinction of humankind and the destruction of our planet Earth. There are many options were everyone can get involved to help the cause and make a difference with this problem. While many people ignore everything about causes and consequences of Global Warming; Global Warming should be everyone's concern.First of all, we will have to start with, what is the definition of Global Warming? "Global Warming begins with sunlight. When light from the Sun reaches the Earth, roughly 30 percent of it is reflected back into space by clouds, atmospheric particles, reflective ground surfaces, and even ocean surface. The remaining 70 percent of the light is absorbed by the land, air, and oceans, heating our planet's surface and atmosphere and making life on Earth possible. Solar energy does not stay bound up in Earth's environment forever. Instead, as the rocks, the air, and the sea warm, they emit thermal radiation, or infrared heat. Much of this thermal radiation travels directly out to space, allowing Earth to cool." (Riebeek, H, 2007 pp1) This is more commonly known and recognize by everyone as the increase of temperature in the atmosphere of Earth.Global Warming 3This is something that has been present and part of the Earth. However, as mentioned by Nodwin (2008) Scientifics have been keeping track of Global Warming since 1880 were they have seen a major increase in two particular times "one beginning around 1910 and ending around 1945, and the most recent beginning about 1976." (pp3). Now we have a clear understanding of what is Global Warming. Therefore, we should be moving to; what is causing Global Warming?Second, we will discuss what is causing Global Warming? There are many causes for the increased levels of temperature related to Global Warming. However, they can be divided in to two groups; natural cause and human cause. Natural cause is anything caused by nature. One of the natural causes is that the Earth goes through a cycle of climate change that last for 40, 000 years. An example of this cycle of climate change is an ice age. "Ice Ages are intervals of time when large areas of the surface of the earth are covered with ice sheets (large continental glaciers)." (Illinois State Museum [ISM], 2007) As said by the NASA (2005) a small group of scientists believe that some of the causes of Global warming could be coming form the energy emitted by the sun. The majority of the climatologists agree that is true but only in a...
