Global warming is the gradual increase in the earth’s surface temperature. There are many things that contribute to global warming human activity, carbon dioxide, some scientists even blame on the sun becoming hotter over time.(Wikipedia) Scientists around the world have been studying the warming of the earth’s surface for the past fifty years. The results that they have achieved are not looking good for living things on the earth. Since 1949 here in the United States, we have unexplained heat waves that can are damaging to the wild life and also elderly people. Some other reasons global warming is becoming more evident and a growing problem is other unexplained events such as: sea levels rising, glaciers retreating, and severe storms without warning. (Wiley 2000-2008)
There is without a doubt that living things such as humans and animals contribute to global warming. Humans contribute to global warming on a daily basis whether it is burning fossil fuels to heat your home, cook your food, or use a car or public transportation. Fossil fuels including carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs) and trosopheric ozone (O3) are polluting the atmosphere by daily human activity. A good example of something that is a part of a human’s everyday life would be a car. A car releases carbon dioxide, nitrous oxide, which triggers the production of trosopheric ozone. Global warming occurs because of these gases being releases are absorbed infrared radiation which is heat from the earth’s surface. This prohibits the natural flow of heat... [continues]
