"close the garage a turn the car engine on in a confined area"

this garage has got a volume of lets say 30 M3
the earth's volume is about 1.4B klm3

now if the carbon content of that garage was 0.04% of 30 m3 that would equal about 12/1000 s of M3 or 12 ML3

Maybe that will worry you and the rest of the wuss brigade
won't worry me
nor will it change the temperature in my garage

got any more genius analogies?
