Let's get real and admit our part in the whole thing; the enormous weight
of scientific evidence points to human beings as one cause of global
warming. All we can control is ourselves, all we can correct is what
we've caused.

One cause, perhaps... but not the only cause, nor even necessarily a
significant cause. One major volcanic eruption puts more stuff in the
atmosphere in one day than we humans can put there in ten years.

I'd like someone to answer me this. If CO2 emissions from human
technoligical activity is a cause of global warming, and if humans were
to, not merely reduce but complete eliminate all CO2 emissions from
technological activity, what would be the net global effect on humanity?

From what I have heard, 2% less CO2.

Wow! That's HUGE!

The present concentration is about 380 ppm and the
observed rate of increase over the last 50 years has
been about 1.5 ppm/a. That rate is a bit steeper
in recent years, but still not much in excess of 0.5%/a.

So you've heard that if humans quite producing CO2
altogether it would reverse the observed trend and
send CO2 concentration plummetting downward
at four times the rate at which it rose over the last
50 years, right?

He's not said anything about the rate of change of CO2 concentration.
The 2% figure means that if all COT emissions from human technology
stopped, the CO2 concentration would, all other things being equal,
eventually stabilize at 98% of its present concentration.
