There is actually a school of thought that thinks that atmospheric CO2 is an indicator, not a cause, of climate change. During periods of increased solar activity, the oceans are warmed, releasing more CO2 into the atmosphere, much in the way that warm soda doesn't hold its CO2 as well as cold soda.
I've never heard that before, but it's a good one.
By the way dudes, vegetarians are responsible for methane pollution produced by cows. Look at all the cows in India that are just chillin' and NOT being eaten.
Oh yeah and cows have four rumens, not four stomachs.
