Yes, of course, no-one disputes this. This does not rule out the
possibility, however, that the increase of carbon dioxide in the air due
to burning of fossil fuels contributes an additional change to the
climate, global warming (though, since the Earth is complex, this
doesn't mean the same increase in temperature everywhere, and might even
mean a decrease on some places), and on a timescale shorter than most
natural variability.

It doesn't matter to the Earth or to life on Earth in the big picture.
It DOES matter to us, though. If the temperature increae is man-made,
then it makes sense to ameliorate its effect by decreasing the output of
carbon dioxide.

Every day in my professional life I hear people describe a symptom or event
(something melted/end-to-end performance has degraded over time), and then
postulate a solution (use less carbon fuel/buy more hardware) without ever
considering that in order for a solution to "work" it must be proved that it
will act on the cause and thus reverse the trend or stop the degradation.

That might be true, but people who don't know what they are talking
about who support a given hypothesis does not automatically rule out
that the hypothesis is true, since it might be supported by valid
evidence.

The biggest fool in the world can say the sun is shining, but that
doesn't make it dark out. The truth of a statement is unrelated to the
competence of the speaker.

Without being able to demonstrate the a causal relationship between event A
and result B, all postulated solutions are logically invalid - ie. just a
wild guess.

Of course. But that has no bearing on the important questions of
whether a) global warming is real, b) it is primarily man-made, c) is
caused by increased output of carbon dioxide and d) the trend can be
reversed or lessened in impact by decreasing carbon dioxide.
