"The contribution to the greenhouse effect by a gas is affected by both the characteristics of the gas and its abundance. For example, on a molecule-for-molecule basis methane is about eighty times stronger greenhouse gas than carbon dioxide , but it is present in much smaller concentrations so that its total contribution is smaller. When these gases are ranked by their contribution to the greenhouse effect, the most important are:
|Water Vapor||H2O||36 – 72 %|
|Carbon Dioxide||CO2||9 – 26 %|
|Methane||CH4||4 – 9 %|
|Ozone||O3||3 – 7 %|
Since human leakage releases water which vaporizes and is destroying the planet more than CO2 why isn't the Al Gore crowd telling people to hold it as long as they can?
