Extra Credit question: What is the predominant "greenhouse gas"?

According to Environment Canada's "One Tonne Challenge" website ( http://www.climatechange.gc.ca/onetonne/english/ see the FAQ page), it's Carbon Dioxide (CO2), followed by Methane (CH4) and Nitrous Oxide (N2O).
Nature creates some CO2, heck breathing causes some, but natural 



Naw!!
The main greenhouse gas is Water Vapour!  Without it the average
temperature on the surface of earth would be minus 15 celsius.  So Water
vapour is responsible for almost 30deg warming, and Carbon Dioxide about
one half of a degree, and all the rest together about another half of a
degree.
Without Water vapour life here as we know it would not be possible --


Water vapour is essentially a constant though. However, if we increase the amount of other green house gases in the atmosphere, that raises the earths temperature slightly, which causes increased evaporation rates, which adds more water vapour, making the problem even worse.

What we need to learn is that our planet, like ourselves, are in a fine balance, as long as balance is maintained, or only changed in small amounts, nature can recover the balance. However changing it .01% may be an easy recovery, changing it 50% (like we have in the past 100 years), and recovery could be a long, difficult process.

Mind you, the GHG problem, may be dealt with in another way, if the Peakoil folks are right. If we find alternatives to oil, and the peak oil folks are wrong, then no problem. If the peak oil folks are right, and we do nothing, um, uh, er were screwed.
