Global Warming
Global warming is a hotly debated theory that states that there is an increase in the earth's average atmospheric temperature (Global Warming). The tedious bickering over if global warming is occurring has stopped with science showing that average temperatures have risen. The argument has now shifted to whether humans are contributing to the warming. Also at debate is whether or not global warming is causing Earth’s climate to change. Both sides of the debate attempt to use science and logic to support their viewpoints.
Proponents to the belief that humans are causing global warming attribute the earth’s temperature rise to emissions/pollutants that collect in the atmosphere, trapping the sun's heat and causing the planet to warm up (Global Warming Basics). .The science behind global warming is simple. Global temperatures have shown a temperature increase over the last 100 years, with a very steep increase in the last three decades. Likewise, NASA has shown the average United States temperatures have increased steadily over the same time period. Other scientists and science organization, from around the globe, have shown rising sea levels. Furthermore, scientists have also studied ice cores, tree rings, and coral reefs in an attempt to study the earth’s temperatures thousands of years ago.
Scientists, in attempting to find a cause for global warming, have narrowed down the potential causes of global warming to three things, the sun, Earth’s reflectivity, and
