Lets get a little more into the REAL Chemical/ Physics aspects versus "GW" Myths.
Before we close the chapter how Maun Lua & the arctic Astro Labs are cheating
with the "moisture corrected Molar CO2 ppm" I think its also necessary to
point out that none of these labs record the ACTUAL barometric pressure,
the ACTUAL temperature and the ACTUAL humidity for the air samples they took.
The MS Spreadsheet calculation simply plugs in a "standard atmosphere" of 20 deg C
etc in and then bloats up the actual ppm to "moisture corrected Molar ppm".
I need not say, that arctic air is cold and dense and in reality You sampled way more air
with 1 liter as You would have if You`ld draw air @ 20 C and >50% relative humidity.
Curiously the Mauna Lua calculation does correct for altitude pressure, after all
"GW" picks even the little scraps that work in their favor..
But even there the actual air temperature & RH of the sample is not recorded...
The "calculation" simply uses the same value for each sampling.
Now on to the "positive feedback effect".
GW with the minuscule amount of Infrared, that CO2 can absorb does not compute
without a "positive feedback"...it`s important to understand this.
Lets now examine how this Hollywood special effect is conjured up.
They quote the Clausius Clapeyron Equation to "substantiate" this "positive feedback"
and since they did have to acknowledge that water vapor IR absorption dwarfs
CO2 IR absorption into irrelevant oblivion, they parrot the CC equation and
the increased amount of water that an increase of atmospheric CO2 allegedly will
cause to happen.
First of all water evaporation has been monitored many decades before this CO2 fraud became
a political issue...and none of this is reflected in the world wide "pan evaporation" data
set. There was NO world wide INCREASE IN WATER EVAPORATION ....!
Furthermore the Clausius Clapeyron Equation says nothing of the kind as GW politics
would like to have you believe.
It`s a simplified equation Chemists use all the time if they don`t have
an actual vapor pressure versus temperature for a given substance at a
pressure and Temperature other than the value listed in the Merck or the "Rubber Index"
of physical data for all known substances.
(I got the entire set these cost ~ U$ 200 per book...
it`s a job requirement for REAL SCIENTISTS to own these..)
So we use the CC equation to extrapolate for a best possible estimate.
But we are talking about water here, not some exotic substance and only someone
who wants to make a theatrical appearance would quote Clausius Clapeyron.
There are vapor pressure versus Temperature to the hilt for water...!!!
Throwing buzzwords around like that is strictly Wizard of Oz theatrics.
Furthermore the CC equation is for a CLOSED SYSTEM...!!!
It will give You the partial pressure any component will contribute to
the total pressure the closed system will be at the temperature You are
interested in, and that is all it will give you.
No way can you pretend that this equation states a "positive feedback"
with an increase in temperature
, unless of course you are sure that your audience `s eyes glazed over
when You mention something like the Clausius Clapeyron equation...
any Chemist would burst out laughing if You cite this equation while
you are talking about common water vapor .
And to apply this equation, chiefly designed for calculating expected
pressure inside an autoclave during a chemical reaction to our atmosphere
is beyond ridiculous.
Every man in the street knows, that when water evaporates and the
relative humidity increases, that contrary to Clauses Clapeyron the
barometric pressure is NOT GOING UP, but is falling.
But Clausius Clapeyron was never even intended for atmospheric
pressure changes due to the predicted increase in partial vapor pressure
of water as the temperature goes up, but it does so rather accurately for
a CLOSED SYSTEM like a vacuum distillation or the opposite
an autoclave for a high pressure environment that some chemical
reactions require.
But the most ridiculous part is citing this equation to "prove a positive
feedback"...
All things considered now, lets look again at this Hollywood "positive feedback" stunt...
1.) the temperature has to go up to begin with, so that the vapor pressure
of water increases...
2.) They say, because more water evaporated and water absorbs a lot of IR (which is true)
that...:
3.) The temperature will now climb more, .....and call it a "positive feedback"....
And no one accounts where the extra heat energy +temperature to raise the water vapor pressure
came from to begin with...!!!!!
What we have here is a typical Hollywood special effect which makes it
possible to pull up global temperature like a cartoon character pulls himself up by his own boot straps...
By the way, the term "positive feedback" comes from the field of electronics...
Differential Amplifiers are wired either in negative or positive feed back mode.
You feed a portion of the amplifier's output back to the input...
The "positive feedback" is when the input and the output are in phase, and
in a negative feedback mode input and output are 180 degrees out of phase
but the cruel reality is, that the extra energy to achieve the "positive feedback" result has to come from
a power supply...it`s not as if you could get an output increase just from
the tiny amount you were feeding back to the input side and thereby "boosted" the
energy with the tiny input...
Too bad, else we could have perpetual motion motors that power
our entire civilization...
Its also amazing how many people even today claim that its
only a question of time till "science" makes this final breakthrough
But Al Gore and "the positive feedback Globalwarming science " pulled his feat off in public
not in a laboratory but on a political stage ...and that`s why he got the
Nobel Peace Prize, instead of the Nobel Prize in Physics
look at this fraud artist posing as a "scientist"...:
He sat down for this Photo with his tree in front of a shelf with Erlenmeyer and Volumetric Flasks, a stack of Petri Dishes and some boxes of filter paper to appear as a "scientist"...
and would not even have a clue what any of that stuff behind him is for...as if You`l need to be in a Chem Lab to count tree rings!
