global warming

Global warming occurs when the levels of greenhouse gasses rise and less
infrared light, or heat, escapes the earth's atmosphere. Thus, the
temperature experienced on Earth begins to rise. Climate change is a part
of the Earth's history. There have been dramatic fluctuations in overall
average temperature for the past 150,000 years that suggest a direct
association with carbon dioxide levels. In the past the temperature highs
and lows have been in tandem with carbon dioxide level highs and lows,
this does not seem to be a coincidence.

Carbon dioxide currently accounts for 0.03% of the gas content within the
atmosphere. However, it has a disproportionate impact on the earth's
temperature. Thus, minor fluctuations in the percentage of atmospheric
carbon dioxide will likely have a significant effect on the global
temperature. The percentage of atmospheric carbon dioxide has risen over
the past century at an alarming rate. Industrial civilization is
essentially driven by fo...
