But... but... but... isn't burning fuel contributing to "man made global warming"?
Burning fuel only contributes to global warming if the carbon in the fuel is from fossil sources that have been sequestered from the environment for millions of years. If you derive the carbon in your fuel from atmospheric CO2 then release it again when you burn it there is no net change in the amount of carbon in the carbon cycle.
