You might want to take a peek back over the history of what we
know of the greenhouse effect and CO2. CO2 was first hypothesised
as responsible for the green house effect at the end of the 19th
century, based on laboratory tests of its spectral absorbtion.
The hypothesis was (and still is) quite plausible, but it was
well beyond science at the time to prove it.

As the ability of experimental science in the atmosphere moved on,
people started embarking on tests to prove the earlier hypothesis.
There have been many attempts, but the proof has been elusive. What
has happened instead is that the tests have shown over the years
that increasing numbers of other gasses are contributors to the
greenhouse effect. So in the 1890's it was thought that CO2 was the
cause based on the hypothesis. The subsequent testing has shown that
other gasses are contributors too, but have not managed to show that
CO2 is a contributor. So the hypothesis has been gradually modified
to correct for CO2's dimishing contribution to the greenhouse effect
us we understand the science better over the years. We are now up to
the point where we can prove something of the order of 70-80% of the
greenhouse effect is caused by water vapour, methane, and ozone,
(water vapour being by far the largest) and we still hypothsise that
the remainer is caused by CO2 as we have no other explaination, and
this is still plausible. 

However, your assertions that "water is not an issue" and "CO2 is
undoubtedly a greenhouse gas" are not credible, based on what we
currently know. Water is an issue (but possibly one over which we
have no direct control). CO2 is still thought likely to be a
greenhouse gas, but it's one that's not understood 110 years after
the original hypothesis.
