Global Warming: Greenhouse Effect

Effectively, the earth and its atmosphere are warmed as a result of the actions of the greenhouse gases.The solar rays as well as the heat generated by the earth are not dissipated entirely and instantaneously into space vacuum because of the gasses which trap them into the earth's atmosphere.This is needed because if there were no heat being trapped,the earth would overall be about 30 Celsius cooler and life would not be as we know it. After millions of years the delicate balance has been fractured, perhaps irreparably in the last 100 years.In the last century humanity's technological advances and the resulting lifestyle choices have increased the production of greenhouse gasses. As more greenhouse gasses are trapped in the atmosphere, more heat is generated. And too much heat causes climate change.
The earth's atmosphere's composition is:

Nitrogen: 78%
Oxygen: 21%
Greenhouse Gases: 1%
The Greenhouse Gases are: Carbon Dioxide, Methane, Nitrous Oxide, Ozone, Water Vapour and Halocarbons
