I am told that the reason for the 9 to 26% range for co2's
contribution to the GHE is because certain IR wavelengths are absorbed
by both water vapour and co2. Why cant scientists determine the % of
these wavelengths co2 absorbs, and the % water vapour absorbs, and
thereby come up with a more definite figure for co2's contribution to
the GHE, rather than just a range?
Again...Im told that the more co2 you add the less is the temperature
increasing effect of the last unit you add. There is a 'saturation'
effect in play. Temperature response to additional co2 isnt linear,
its logarithmic. This makes sense, especially when someone uses the
analogy of adding coloured dye to a clear glass of water; initially
when you add a little dye you get a large discolouration effect; the
more you add the less discolouration effect you get, until you get
virtually no effect whatsoever no matter how much dye you add. This
may seem like a silly question (but im not a scientist so im allowed
ask 'em), WHY should temperature response to co2 increase but
logarithmic and not linear?

In many models CO2 increase is in fact logarithmic, based on normal
statistics and based on power law formulas (which increase
logarithmically, if you change the axis).
BTW, the founder of the "CO2 increases air temperature" theory is a
certain Swedish scientist named Arrhenius, who also discovered the
formula for your example of dye diffusing through a glass of water--
and found that it is in fact proportional to the concentration of the
dye, and thus is in fact logarithmic ( e.g., Y(x) = k*X^n, where
n=concentration factor, k= a constant, so log(Y) = K + n*log(x),
simplifying.

Alas, your questions cannot be answered in terms that would be
comprehensible to you, unless you have completed some years of study
in the relevant sciences and are familiar with the hundred or so
concepts and a thousand or so jargon words that make up the present
study of climate science.
Like Ray has told you, just come here for the flame wars - or go and
study science at your nearest uni.
Scientist didn't detemine it. Politicians stated it. It isn't base
on research or evidence. It's base on what they think people will be
dumb enough to believe without asking any questions. And they were,
for the most part, getting away with it until about a year ago when
myself, James, O'hara and others here in this NG started asking
questions.

Preliminary efforts in this regard showed nothing dramatic.
Consequently the GW cultists abandoned this approach.
GW whackos fear nothing more than conceptual clarity.

Possibly only because the percentage of water vapor
varies so much, but I don't think you can directly convert
"effect" to temperature.

At a constant temperature and relative humidity
they probably can.

Temperature is determined not only by the
amount of heat, but also by the mass of the molecules,
heavier molecules move slower (but still many miles
per hour) than lighter molecules.
And the amount of heat that a certain chemical
molecule can hold depends on the specific heat, if
I am not mistaken, Einstein developed a formula
to predict the specific heat of chemical elements,
or at least some types.
And water vapor can act as either a cooling
medium by evaporation, or by shielding the sun if
clouds form (I think clouds are water droplets), and
a stronger warming medium if the clouds prevent
heat from being radiated to the black sky as it is
on a clear night (there is no dew or frost when the
sky is cloudy).
A clear understanding of the role of water
vapor still doesn't allow the role of water vapor to
be specified as a constant, the same way CO2
or CH4 can.
And the 9 percent is probably not CO2
alone, that is more like the total for all the trace
gases except water vapor (only O2 and N2
are not trace gases).
And this seems to be the reason the
role of water vapor is not made prominent,
it really is the dominant factor in 90 percent
of the atmosphere, and it is misinterpreted
for that reason and under estimated relative
to the CO2 effect.
Water vapor is not dominant above
about 60,000 feet, but 90 percent of the
atmospheric mass is below 60,000 feet.
I am very concerned when physical
properties are misinterpreted because it
can have disastrous effects, truth is very
important in science.
Joe Fischer
Well you know it's hard to prove the impossible. You would think that
someone could at least provide a first order computer model showing
that warming is even possible from additional carbon dioxide in the
atmosphere.
Uh, you and your ilk came here and posted lies. You didn't ask
questions. Like the lie in the first 2 sentences above.

You fear losing your blood money.
At a given location and time they can measure this quite well.
The problem comes from estimating this globally over a period
of many years.

It's call infrared "band saturation."
There is only so much energy the Earth radiates in
any given portion of the infrared spectrum. Once
that is absorbed and scattered, there is no more.
Unfortunately, band saturation isn't going to
save us from global warming. There is more than
enough energy available to do lots of damage.
>From the various text books and scientific sources i have consulted so
far they all give a range of 9-26% for co2 alone. They give about
15%-36% for all greenhouse gases, discounting water vapour and clouds.
Thats what im being told. They all seem to be rather consistent on
this point. I just want to get a clue how they are actually getting
these figures.
Im looking at graphs like this one:
http://www.atmosphere.mpg.de/media/archive/1393.jpg
The above is a pretty poor graph. I've seen better in text books.
These kinds of graphs describe the amount of IR radiation being
emitted by the surface (red line) and the amount escaping the system
higher in the atmosphere (blue). The difference between the two lines
is the greenhouse effect it would seem to me.
Now we apparently know what wavelengths the various gases in the
atmosphere absorb via laboratory experiments. We take that knowledge
and look at the various graphs like the above, which i think are
derived from satellite measurements (atleast the blue one is). We see
c02 absorbs from i think 12-18 microns (i think???) and this would
mean about 9-26% (3-9 oC) by looking at such graphs and doing a few
calculations. There is an overlap with water vapour at certain
wavelengths, hence the range of 9-26%.
This is how i believe they are working things out....errrr???

But there is a degree of saturation none-the-less. Assuming first
that temperature response to c02 increase is a linear thing. And
accepting that c02 comprises just 9% of the GHE, which is roughly 3
oC. If we then double atmospheric co2, we would get another 3 oC
just from doubling co2...without even counting feedbacks. But I think
the IPCC says something like 2.5 oC (mid range figure) warming for a
doubling of c02...and thats with feedbacks. For c02 doubling alone
they calculate something like 1.2 oC. So obviously there is saturation
somewhere or other.
I believe thats the standard line above. Im still not completely
certain how they are working all this stuff out. Itd be nice to
know....More reading i guess!!!!!!!
It must depend on what it is that percentage is for,
and how it is used in the model.
Greenhouse gas numbers are only for trying to
mimic the observed average temperatures with those
derived from a model, and if water vapor and clouds
are discounted, and local sea surface temperatures are
not considered, then the percentages are different than
if all things are considered.
The total thermal heat content of the top 3.5
meters of the ocean is more than the total heat content
of the entire atmosphere.
The amount of CO2 in the atmosphere is only
388 / 1000000 and where there is cloud cover, in the
daytime, it could be considered to be zero, but at night,
the cloud cover has a far greater potential for holding
heat in than all the greenhouse gases.
And when the Sea Surface Temperature is
looked at, the ocean becomes the biggest factor.
http://podaac-www.jpl.nasa.gov/sst/images/reynolds.gif
Control of local air temperatures are more important
than greenhouse gases, and it is water vapor and the
temperature of the ocean, and the plus or minus effect
of evaporation, precipitation and cloud cover according
to daylight or night that regulates the local air temperature
and modeling all of this complex regulating effect and the
big heat sink and source of the heat from the ocean is
not possible using only the greenhouse gas effects alone.
Rather than study greenhouse gas theory, search
google for air temperature control or air temperature
regulation.
Greenhouse gas theory is just a simple explanation
of the general reason the surface of the Earth does not
fluctuate or be colder than it would be without those gases,
which means only N2 and O2, and no water.
It is not even rational to try to model realistic climate
conditions on the basis of average surface temperature,
and that is the problem.
The greenhouse gas theory is a general reason
for a warmer planet, it is not a method of determining
the local temperatures, and an average temperature
is meaningless.
Rather than devoting all study time to greenhouse
gases, include reading articles like;

In a nutshell, the leaders of the IPCC projects are
fixated on the greenhouse gas effect, which really is not
the reason for the temperature anyplace on Earth.
All greenhouse theory says is that the temperature
at 40 degrees North Latitude can NOT be below freezing
unless cold air from the arctic moves down across the
region.
That is it as far as greenhouse theory goes, nothing
more can be pinpointed.
It is sad when one person becomes fixated on some
shallow idea, but when a large political group tries to force
that fixation on the whole world and demands near impossible
tasks by everybody, possibly even denying them the means
to keep warm, it is not just sad, it is insane.
The attitude of the most vocal and abusive AGW pushers
here is evidence enough that they are not only perverted, but
also depraved.

This is a misconception. A closer study of the 'kinetic theory of
gases', reveals that this is not true. The heavier molecules absorb
the same energy at a lower velocity. Therefore the perfect gas law is
possible.
(also see kinetic theory of gases in this text)
Any gas, except the few abnormal gases, obey the perfect gas law at
low pressure. At higher pressure, differences in radius affect mean
free path and deviations occur.
The pressure of a gas is due to the collective momentum of the
molecules against the side of a vessel. The number of collisions
multiplied by the velocity of the molecules determines pressure. The
number of collisions increases as a direct proportion to velocity.
Therefore pressure is velocity x number of collisions. Mean kinetic
energy increases as a square to velocity. Therefore the velocity
increases inverse to the square of the mean kinetic energy kT, which
is direct proportion to temperature. Inverse square of velocities, x
inverse square of number of collisions = 1. (square root x square root
= 1)
Therefore pressure increases also as a direct proportion to
temperature. This applies to all gases. A good example are the inert
gases which are molecules of only one atom. These weigh very much
differently. But are indistinguishable for temperature, and even heat
capacity. Heat capacity is the energy that must be absorbed from the
environment in order for the molecules to have the kinetic energy of
motion. The heavier molecules absorb the same energy as lighter
molecules at lower velocity.
The same if you pushed on a truck or a car with the same force. The
lighter car would move faster than the heavier truck. But their
kinetic energy would be the same and the force they would deliver as
they collided into a wall would be the same and in accordance with the
force that was delivered to incur their motion.

Isn't that what I said, certainly it is the same energy,
it is just like billiard balls having different masses (weight),
if a heavy ball hits a lighter ball, the energy of each is
changed, resulting in each having the same "temperature"
after (enough) collisions.
A lighter molecule needs a higher velocity to exert
the same pressure on the sides of a container, a heavier
molecule has a lower velocity at the same temperature.
Hydrogen molecules move fastest of all at the
same temperature, but an advanced description of this
should be more precise as to the relative speeds.
Note that the speed of sound depends on this,
and once the gas/medium is specified, such as air,
then the speed of sound depends on temperature.

Ok, I guess, it should be obvious that there needs
to be a specific relationship of energy to all the factors,
temperature, molecular mass, velocity, and maybe other
things, like specific heat of various chemical elements
and compositions.

The heavier molecules have the lower velocity,
the lighter ones have the higher velocity, but chances are
momentum formulas are not used, kinetic energy formulas
are more likely used.

I guess that's right, but in a head on collision,
the lighter vehicle can be accelerated backwards by
the heavy truck, so be careful about using the brick
wall analogy.
A gnat flying into the windshield of a big truck
suffers more than if he flies into a brick wall.
And the number of accidents, and severity of
injuries would be less if more people knew that the
stopping distance on dry pavement is a square
function of velocity, and is derived using the kinetic
energy formula.
Applying all this to the atmosphere helps in
understanding what has to happen if a molecule
absorbs energy, while all three energy transfer
processes are ready to proceed, radiation has to
hurry, else conduction (the collisions) will probably
transfer [the/part of] energy to other molecules.
Convection doesn't have priority until there
is time for buoyancy of a number of molecules to
occur. While radiation can be fast, it may not
all happen at once, and collisions happen often,
and it is not a simple matter to describe/anticipate
whether or not radiation wins out before conduction
occurs in collisions.

in him and in kdeathrage was to test them to see if they understood

It follows directly form infrared molecular spectroscopy, that
is the study of how molecules absorb and emit light in the infrared
region of the spectrum--coupled with the application of the law
of conservation of energy.

There are two clear ways to approach the problem. One
is to determine how much greenhouse effect would remain
if only one greenhouse gas were removed. The other
is to determine how much greenhouse effect would
remain if all but one greenhouse gas were removed.
That gives you two different answers. Some people may
want to average them, so now you have three.
But water has a very high boiling point compared to other
greenhouse gases. Therefor its concentration in the
atmosphere is highly variable. Since there is a lot of
uncertainty as to how much water vapor is in the
atmosphere and how it is distributed geographically,
seasonally, and diurnally, it is very difficult to accurately
do the two different problems described in the previous
paragraph.
OK?

You say nothing about how the heat is applied to generate the
pressure. Infrared energy is measured in joules, but some gases are
transparent to it, thus no heating, no kinetics, no pressure increase.
Other gases are opaque to IR, thus they absorb joules of energy,
convert it to kinetic energy, pass it to neighbors in the manner in
which you describe.
You must must include the form of energy which goes into heating the
gases in the real world. The real world is not some abstract
hypothetical theory.
A common blackbody IR radiation frequency is 10.7 microns, the
frequency built into satellite detectors to observe H2O vapor
concentrations shown as clouds.
A length of 10.7 microns is smaller than the dot on the end of this
sentence. If that length is spun every which way around it's center
the ends define a spheroid shape.
Using the Ideal Gas law we can compute the number of air molecules in
a sphere whose diameter is 10.7 microns. Using the accurately measured
amount of CO2 in the air of 381 parts per million we can compute the
fraction of air in a spheroid 10.7 microns in diameter which is CO2.
The computed answer is: 6,769,010 molecules of CO2.
We can perform the same computations for all the photon wavelengths of
blackbody radiation to determine the energy absorption potential of
air at different wavelengths of IR radiation.
Joules is an abstract term. Nobody has ever seen a joule in the
laboratory or in the real world. Photons are real items and nobody can
see anything without them -- our eyes are sensors for some wavelengths
of photons, and we have prothetic eyes to see wavelengths that our
natural eyes cannot see,
Photons are real. Joules are abstractions only meaningful when coupled
to real things. IR photons are real and are seen by satellites with
artificial eyes tuned to 10.7 microns. Nearly every photograph of the
top of a hurricane you have ever seen was taken with a 10.7 micron
sensor.
The gases take up energy in the only three ways allowed by the
universe: (1) Conduction, (2) Convection, and (3) Radiation.
It makes a difference which form of heating energy is applied, and it
makes a difference which form of heating any gas molecule can respond
to. All fluids (including gas or liquid) use convection to spread
heat, which is differences in pressure within the vessel. All would
use conduction, which is contact of gas molecules at the wall of the
container. Some energies, no matter how many joules would be totally
ineffective: microwaves, sound energy, TV waves.
TV radiation passes through the air without heating it. TV stations
broadcast at 100,000 watts, 360,000,000 joules, without heating the
air.
One must be aware that different chemistries are different because
they are not the same, and cannot be all lumped together as the same.
CO2 is a different chemistry from other parts of the air. It responds
to specific photons that other air chemistry molecules do not. It
converts energy, photons, joules (abstraction), into heat which is
real and measurable. It only selectively converts photons it has a
sensitivity for and not others.
As stated above, conduction is a primary heat transfer means for most
elements and compounds (good heat insulators, like asbestos, being
among the rarer exceptions). Some gases are chosen a preferred because
they have exceptional molecule-to-molecule heat transfer properties,
which is why the choice of gas for Solar Stirling Engines is not air,
and it is not most gases which are cheaply available -- but instead
Solar Stirling Engines uses hydrogen gas as the preferred heat
transfer working gas because of unique chemical properties not shared
by other gases. Rapid heat-up, rapid-cool-down, are required for Solar
Stirling Engines.
You are careless and reckless in your statements. After being
corrected in public you continue to promulgate falsified statements.

that bit about the day night bit cooling and heating "sorry pal thats

The other source of warming is the gravity of planets the moon and the
sun interacting with earth pulling at it from all directions , this
turns Earth and many other planets and moons inside out. Analogy is
placing a thick frozen soup in a pot a slowly heating it till it boils
and then reducing the heat to a simmer.

There would be some interference among CO2 molecules, so with the
interference, the increase would be expected to be sublinear. As to
why it doesn't fall off as
(x)^0.75 or some other obscure ratio, I figure the theoretical
argument went something like this:
1/ e = 0.367879... is the limit as x goes to infinity of ( 1- 1/
x)^x
(1/e)^n is the limit as x goes to infinity of (1 -
n/x)^x
Photons being reflected from Earth's surface will be intercepted by a
specific
CO2 molecule a certain fraction of the time, say n/x. With X CO2
molecules in the atmosphere, each having an equal chance of catching
the photon, the probability that the photon will escape into space
without being captured by a molecule is
( 1 - n/x)^x. With X quite large, and n/x quite small, that chance
of capture is just
1/(e^n).
Double the number of CO2 molecules, and the probabilty that the
photon escapes capture by each molecule is ( 1- n/x)^2x = (1- n/x)^x
squared.
Since (1- n/x )^x = 1/(e^n), (1-n/x)^x squared = (1/(e^2n) .
The log of (1/e^2n) is just half of the log of (1/e^n) . That's
where the logarithmic effect of CO2 comes from.
- A. McIntire
All of your arguments are bogus, based on the assumption (bogus) that
molecules at room temperature are virginal (bogus) and can absorb one
photon at a time (bogus), and must emit one if they receive another one
(bogus).
70 degrees Fahrenheit, 21 C, is 294 degrees K, chock full of so much
energy that oxygen has transitioned two phases from solid to liquid to
gas. So too have the other gases. Any material in the universe found in
the gasous state is chock full of lots of photons, more than you can
think about. They are in no-way virgins.
Satellites use the 10.7 micron frequency for IR photographs of weather,
so I use that 10.7 micron wavelength as an example. A length of 10.7
microns (smaller than the period at the end of this sentence) taken as
the diameter of a sphere would contain 6,769,010 molecules of CO2 if that
sphere was filled with air at normal temperatures and air pressure.
It is just as appropriate to talk of CO2 molecules per photon as it is to
say photons per CO2 molecule.
Trying to picture the quantum world using billiard balls models or wee
little solar systems is a fools errand that leads you to say stupid
things as we saw above.
It may be hard for you to comprehend the internal machinery of atoms, but
when a photon is absorbed it no longer exists as such. There is not one
atom in the universe above zero degrees Kelvin that doesn't contain the
energy quanta of many photons.
Infrared, like television, is part of the electromagnetic spectrum. TV
waves are not solar systems or billiard balls either. You can use metal
of certain kinds to screen or block TV waves, or you can use it to
conduct them through cables and distribute them to paying customes along
a route. You can even use the exact same cables simultaneously to route
internet communications in the opposite directions as the incoming TV
waves. Isn't that a miracle? Isn't that about 100 times beyond your
understanding of Electromagnetic Radiation?
Now try to get used to the fact that you know nothing of any importance
about anything of any importance, and nobody who is not almost as dumb as
you are cares to bother to try to explain your many mistakes to you.
Because you are a hostile anti-social homicidal killer willing to murder
the entire planet, really, even other killers don't find you very
attractive or worth explaining things to you. You might try working on
your people skills: once you can fake sincerity the rest is easy.

These two cities are about the same latitude and elevation. They have
extremely great differences in water vapor content year round.
The spectroscopic evidence of the water vapor is here, but there is no
evidence whatsever of effect of bolstering temperature. Even in
nighttime temperature drop.
The basic grenhouse theory stipulates 100 - 200 Wm-2 of radiative
forcing from water vapor. No evidence of it here.
This is clear proof that it does not happen at the surface. So where
does this magical thing happen that all the followers of the doomsday
theory believe in so much??
If these great differences in water vapor cannot show the effect of
'grenhouse' gases on temperature, why should anyone believe that
change of 1/10000 of CO2 should be such terrible threat to the
temperature stability of the earth??
The scientists of climatology appear to have no interest in actual
scientific rendering of their postulate. Perhaps they will not like
the conclusions of those that do render them to science.

Ditto because you bite eh owwwww!
These basic facts entirely disprove the concept that grenhouse gases
affect temperature of the earth. I know that that is not what many
enjoy to believe. Those with carreers in AGW are certainly not
interested in direct science. Those with monetary investement do not
care what the science shows, they wish to ram their fraud through
anyway.
There is no valid claim of 4Wm-2 returned to the surface from
grenhouse gases and this is direct proof. Therefore it is also
completely impossible that grenhouse gases have any capability to
cause warming of the oceans. Any indication of warming ocean
temperatures is proof of another and natural cause of temperature
fluctuations other than anthropogenic causes.
Climate is temperature over long periods. What change are you talking
about? Fluctuations are natural. The mass of the earth, atmosphere and
ocean is very great. There is no science to support that humans are
affecting overal temperature at all.
But it is all just words and postualtion if you cannot quantify or
mathematically prove your idea. We could say that cow farts are going
to cause the earth to tilt over. But if you cannot mathematically
establish this, it is nonsense.
There is enough data and means to check this postulate of CO2 caused
warming. But the simple scientific approach is not taken with this
data or investigations. The initial assumptions and definition of
words is taken as foregone, and the logical points are built upon
these assumptions.
Although they have no direct science, these scaremongers claim to have
enough certainty of doom to insist upon complete control of the use of
energy. Any dissent is not very lightly tolerated within this psuedo-
science business of milking the taxpayer and demanding economic
control.
The AGW movement has succeeded because they always claim to be working
on something that may affect humanity greatly. Thus they scare
administrators into funding. They enjoy this and are not about to
admit to any science that sheds doubt upon their propounded beliefs of
the catastrophe from which they aim to save everybody and all the
funding this brings to find out if it is TRUE?
