Water vapor is indeed a greenhouse gas, but the amount in the

I got into a discussion with someone about CO2 being a greenhouse gas
but he stumped me with a comment about "saturation".

CO2 has these huge absorption bands in the IR but (and I'm looking at
my super-duper atmospheric spectrum wall chart) it's a BIG
absorption. I mean, it looks like CO2 is absorbing 99.999% of the IR
light. So what does it matter if CO2 concentrations go up and the
absorption increases to 99.9999%?

I didn't know how to counter this arguement. Any ideas? Or is this
guy correct and CO2 conc. is a paper tiger?

Don't know for sure, but I think I agree (I need to
cross the "i's" and dot the "t's"), but there is a
parallel thread in the group Sci.physics.foundations,
wherein Dr. Francis supports your thesis.

My personal reasoning supports both of your PoV's.
If I have a standard set of sunglasses, that reduce
light by 1/2, then if I wear one on top of the other
I would reduce the light to 1/4, IOW"S (1/2)^n.

So adding more sunglasses dimishes the effect
of blocking or retaining heat, so if I wear 8 or 10
sets, we have a "saturation" effect, beyond which
adding GHG's will have small nominal effect, is that
agreeable?

If I understand correctly, we have actually reached
that saturation of CO2 and H2O, and changes will
make very little difference.

That returns to the idea that the Sun is actually
going through a heating cycle, which is evident,
and the human caused GHG's is mostly BS.

Yes, Ladies and Gentlemen, I think we need to
deploy resources properly. Let's work the problem
and respect causal inputs.

If the CO2 is absorbing 99.999% of the IR, I wonder what is making my
skin
warm when I stand in the sunlight. Any idea?
