A lot of science that I was going to write and thus avoided sore fingers

I would just like to add that the source of the excess CO2 that is now
being measured is fossil fuels. This is no guess, the isotopic ratio of
the carbon in the "new" CO2 is identical to that found in fossil fuels.

I also note that Andre did not explain how the increasing levels of CO2,
a known greenhouse gas, could be failing to produce a greenhouse effect,
instead he said that this was "irrelevant".

How do scientists recognize 'new CO2'? Is it by the gauche manner of the
molecules? Their clumsy attempts at Brownian motion?

The 'greenhouse effect' of CO2 is many times smaller than that of H2O
so Andre is right; it is pretty irrelevant.

**No, it is not and no, he isn't. CO2 is less influential on global warming
than water vapour, but not by "many times". (
http://en.wikipedia.org/wiki/Greenhouse_gas ) CO2 is STILL a major
greenhouse gas. As the planet warms (due to the influence of extra CO2),
then more water vapour will enter the troposphere, thus accelerating the
effect still more. We can't control water vapour, but we can control CO2. We
should do so, and do so now.
