Whoops, you're absolutely right :
Greenhouse gas - Wikipedia, the free encyclopedia
Quote:
The most important greenhouse gases are:
* water vapor, which causes about 36–70% of the greenhouse effect on Earth. (Note clouds typically affect climate differently from other forms of atmospheric water.)
* carbon dioxide, which causes 9–26%
* methane, which causes 4–9%
* ozone, which causes 3–7%
Note that this is a combination of the strength of the greenhouse effect of the gas and its abundance. For example, methane is a much stronger greenhouse gas than CO2—about 25 times more heat absorptive, but is present in much smaller concentrations.

Question: If you got the hydrogen from water in the ocean, then could you call that "closed loop"?
Question: What is the current world-wide automobile/CO2 production versus a "100% replacement" with fuel cell cars?
