One of the comments from the site includes this tidbit:

Every gallon of fuel we burn through an internal combustion engine creates 20+lbs of CO2.

I don't think physics works that way.

They know most people are stupid, and will buy it.

That’s why they’ve dumbed-down education.

Considering the gas it’s self only weighs 6 pounds per gallon in the first place.

[Bob434]

A gallon only weighs 6.073 lbs or so. There must be some special kind of demonic liberal witchcraft going on to create 20+ lbs of co2 lol

[HartleyMBaldwin]

Every gallon of gas does produce about 20 pounds of CO2 when burned. Remember that each carbon atom combines with two oxygen atoms from the air.

Gasoline is mostly long chain carbons with hydrogen attached.
Atomic weight of Carbon =12
Atomic weight of Oxygen =16
Atomic weight of CO2 =44
He is about right on his calculations. However, do not worry. CO2 is plant food.

The people who write this crap are idiots. You become dumber just by reading what they write.
