How can 1 gallon of gasoline at approx 8lbs per gallon churn out 19+ pounds of carbon dioxide? I realize the combusted carbon combines with 2 additional oxygens, but CO2 is a much lighter molecule then the complex aliphatic hydrocarbons gasoline is made from. I am not arguing this but compared to industry (including power generation) cars are a small chunk of the CO2 output. One volcano eruption produces more CO2 then atleast the last 100 years of human activity. I am just curious where all these statistics are coming from. The big problem is there are no conclusive statistics in the "global warming" argument because all the statistics come from one special interest group or another and are all skewed in their respective favors.
