Magnitude of Green House Effect and the contribution of Carbon di oxide

Global warming is due to many factors such as the variation in the incoming solar radiation, earth´s magnetic field, atmospheric conditions such as cloud formation, aerosol content, Green House Effect, etc. In the present study, the contribution of Green House Effect is being explored. First, a theoretical estimate of Green House Effect is presented with a verification using the observed values. Then, the contribution of the Green House Gases based on its concentration is calculated. Of the various Green House Gases, we have taken Carbon di oxide, Methane, Nitrous oxide, Chloro Fluoro Carbon-11 & 12 for our study. Of these gases, the contribution of carbon di oxide alone is found to be about 66% of the total magnitude of the Green House Effect.
