Maxed out already??????? Please enlighten me as to how you've come to that
conclusion.
Actually I do know how CO2 warming works and unfortunately you haven't a
clue and you continue to argue with your narrow-minded, finger-pointing and
branding me a "leftist". Whether I am or not is not the issue here.
FYI: The reason CO2 affects T is because it can absorb IR (I'm assuming
that's what you meant by a "VERY" small segment of the light band). And it
does so, because the wavelength of IR is about the right value to interact
with the O-C-O bonds. A carbon atom attached to two Oxygen atoms in a
linear array, with C in the middle. When IR radiation hits the CO2 molecule,
the C atoms move back and forth, vibrating back to something that is more
linear. That's how CO2 traps heat.
The experiments showing the heat absorbing effect of CO2 go back to the 19th
century, when John Tyndall, in attempting to explain the ice ages, examined
the "heat blocking" effect of certain gases. He discovered that CO2, water
vapor and methane were all very effective at blocking (absorbing) heat.
This is what I was trying to point out regarding the feedback effects when
CO2 values become elevated in the atmosphere.

IR radiation is trapped within out atmosphere, and is now at higher
levels in the atmosphere than ever recorded in any ice core in the past
800,000 yrs. (about 375 ppm today, compared to a long-term historical
high of 270 ppm)As I pointed out before, CO2 is a greenhouse gas that maxes out in the
neighborhood of 200 ppm. But by all means try to believe that somehow it
behaves differently than science has shown it does.

Quoted message said:2. CO2 has increased from 313 ppm to 375 ppm since just 1960.
We most certainly have to be concerned about increasing levels of CO2. The
problem is that man is only the tiniest portion of that increase and the
other 97% is natural.Quoted message said:3. No one has yet observed in the 800,000 year ice core record a greater
rate of T increase or a greater rate of CO2 increase.The leftists have been quoting CO2 levels from tests performed on bubbles
obtained from ice in glaciers. It has since been shown that the CO2 in
these bubbles IS NOT stable and CO2 slowly filters out of the bubbles into
and through the surrounding ice and that the _supposed_ level of 280 ppm
was completely wrong and suspected to vary around the same neighborhood it
is today.Quoted message said:4.. The arctic ice cap and glaciers throughout the world are at their
smallest sizes ever.Yet strangely after they spent all that time decrying how those glaciers
in Austria had been there for millions of years, as they melted away there
were HOUSES and VILLAGES under them. Funny thing about stupid people -
they tend to believe anything someone they believe to be an authority
tells them.Quoted message said:6. One of the problems in understanding the climate system is in
understanding the feedbacks. If we pump more CO2 in the atmosphere, then
the atmosphere warms; this can lead to increased evaporation off the
oceans, which means more water vapor in the atmosphere, so more heating.
A negative feedback is that with increased CO2 there is global greening
(which is very real) so there are more plants to absorb more CO2.Please learn how CO2 warming works - it works by blocking a VERY small
