Can you site a source that agrees with this. There is lot of conflicting
information available, but none of it shows the concentration as being stable. The
UN site is the closest, but it show fairly wide variation in concentrations on
cyclical basis (from a low of around 180 ppmv, to a high of over 300 ppmv - not
including the current period). See the following references (some of which may be
peer reviewed):

Can you site some evidence? Just saying I an wrong does not make me wrong.

Actaully I think my opinion on global warming is just as valid as yours. How many
peer reviewed papers have you written on the subject? How much research have you
done on the subject? What qualifies you as an expert on global warming? You may
have a PhD in chemistry, but other than knowing the chemical properties of CO2, I
don't see where this gives you any special insight into global warming. It seems
to me that you picked your side of the global warming debate based on politics,
not science. I picked mine becasue of self interest. I am not interested in having
my life rearranged becasue a group of liberal chicken littles are claiming the sky
is falling.
