What is the sensitivity?

<b>What is the sensitivity for each 1% of the most prolific "greenhouse gas" (namely water vapor) in Earth's atmosphere?</b>

To help any of you answer the question, here are some facts:

<b>Fact 1:</b>  Water vapor absorbs a significant amount of incident solar radiation as shown <a href="https://www.google.com.au/search?q=solar+absorption+spectrum+images&amp;biw=1920&amp;bih=989&amp;tbm=isch&amp;tbo=u&amp;source=univ&amp;sa=X&amp;ei=Yv8FVYXhAYvo8AXsyoLgAg&amp;ved=0CDEQ7Ak#imgdii=_&amp;imgrc=nZPQWcmcfvv7rM%253A%3BZsBVhE4WQrQ-5M%3Bhttp%253A%252F%252Fupload.wikimedia.org%252Fwikipedia%252Fcommons%252F4%252F4c%252FSolar_Spectrum.png%3Bhttp%253A%252F%252Fen.wikipedia.org%252Fwiki%252FAir_mass_(solar_energy)%3B800%3B595" rel="nofollow">here</a>. The atmosphere absorbs about 20% of incident solar radiation and that absorbing is not by nitrogen, oxygen or argon. (Carbon dioxide also absorbs incident photons in the 2.1 micron range which each have about 5 times the energy of 10 micron photons coming up from the surface.  On Venus over 97% of the energy from incident solar radiation is retained in carbon dioxide molecules.)

<b>Fact 2:</b>  The concentration of water vapor varies between about 1% and 4%.  (The concentration of carbon dioxide above Mauna Loa is 0.04% and, as <a href="http://americantraditions.org/Articles/Positive%20Proof%20that%20Carbon%20Dioxide%20(CO2)%20Is%20Not%20a%20Driver%20of%20Global%20Warming.htm" rel="nofollow">this</a> graph shows, temperatures there have not increased since 1959.)

<b>Fact 3:</b>  The IPCC claims that water vapor does nearly all of "33 degrees of warming" of Earth's surface.  It must do most of it because it dominates CO2 in concentration and also in the number of frequency bands in which it absorbs and radiates.  But in fact water vapor lowers the "lapse rate" so that the temperature profile rotates downwards at the surface end, making the surface cooler.  (In fact, as per my <a href="http://www.climate-change-theory.com/Planetary_Core_and_Surface_Temperatures.pdf" rel="nofollow">paper</a>, there is no 33 degrees of warming being done by any back radiation because it is gravity which props up the surface end of the temperature profile.)

When you have answered the question, work out how much hotter the IPCC conjecture implies a region with 4% water vapor would be than a similar region with 1% water vapor at a similar altitude and latitude. Then look up the study in the Appendix of my <a href="http://www.climate-change-theory.com/Planetary_Core_and_Surface_Temperatures.pdf" rel="nofollow">paper</a> and see what real world data tells us about how water vapor cools rather than warms.  And if you don't believe my study, then spend half a day doing your own.

Finally, note that it is quite clear in the energy diagram <a href="http://climate-change-theory.com/PSI.html" rel="nofollow">here</a> and the text I wrote beneath it that they have certainly added 324W/m^2 of back radiation to 168W/m^2 of solar radiation in order to use this in Stefan Boltzmann calculations to determine the temperature of the surface.  Obviously they worked out by difference what the back radiation figure had to be and made it 66% greater than the 195W/m^2 of upward radiation from the atmosphere to space.  They need not have bothered, because their whole paradigm is wrong, because they ignored the fact that the Second Law of Thermodynamics tells us that gravity forms the temperature and density gradients - which represent the state of thermodynamic equilibrium.

Why would anyone credit

Steve,
Sorry mate, but this is laughable:
<blockquote>Keyes, I think Dr. Connolley is generally preferred in these circumstances.</blockquote>I'm laughing. You've made me laugh.

Why would anyone credit what "[you] think" on the subject of contemporary social mores among humans when your concept of etiquette begins with calling me "Keyes"? ROFL

As for your suggestion that our gracious host is such an insecure mediocrity that he'd actually insist, with a straight face, in 2015, that everyone who visits his <i>blog</i> validate his supposed completion of a PhD on an unknown subject—though he doesn't even see fit to mention this anywhere else on the page!—well, what can I say, Steve? <i><b>Nobody</i></b> could be as pompous as that. And (a posteriori) they're NOT, are they? Look around. <i><b>Nobody on this page</i></b> typed "Dr. Connolley" until you did, Steve. Not even our host. Who signs his blog 'William Connolley.'

Yes, you're the epitome of class

Yes, you're the epitome of class and hence entitled to lecture others on the subject.

Censored again!

As Cook wrote on Skeptical Science

New comment on your post "rigorously eschewing the unfortunate ad hominem arguments that too often characterize public “debate” about human-caused climate change"
Author: Tom Fuller
Comment: Marco, (snore)

"As Cook wrote on Skeptical Science, “We’re basically going with [a definition of] AGW = “humans are causing global warming” Eg [sic] – no specific quantification.” This is very different from what the IPCC says–that humans have caused 90% of global warming."

During the study that was the basis for QTC, two teams of citizen scientist analysts classified papers using 7 different categories ranging from explicit endorsement to explicit rejection. The Cook et al study data base has seven categories of rated abstracts:
1. 65     explicit endorse, &gt;50% warming caused by man
2. 934 explicit endorse
3. 2,933 implicit endorse
4. 8,261 no position
5. 53     implicit reject
6. 15     explicit reject
7. 10     explicit reject, &lt;50% warming caused by man

The highest level of endorsement–“Endorsement level 1, Explicitly endorses and quantifies AGW as 50+%.(human actions causing 50% or more warming)” was assigned by the raters to a grand total of 65 out of the 12,000 papers evaluated. This certainly is a weak finding. Even combined with level 2’s 934 papers it amounts to less than 10%.

&quot;“Let’s walk through that sentence again. The Cook et al 97% paper included a bunch of psychology studies, marketing papers, and surveys of the general public as scientific endorsement of anthropogenic climate change. http://www.joseduarte.com/blog/cooking-stove-use-housing-associations-white-males-and-the-97

The movie District 9 ... was an allegorical reference to racism in South Africa. Fitting that AndPhysics and Chinky Stoat help each out so much.

I'm with William

Comment: [Redacted -W],

I'm with William. Please stop self-censoring on our account. If you opine something, say something.

People are beginning to talk. An unkind meme is now in general circulation to the effect that you lack the verbal and cognitive dexterity to come up with a clever insult, hence your continual and cliched retreat to the "I can't tell you what I really think of you" position. Which is a fiction, of course: William (and I!) would gladly welcome the historic event of your giving someone a piece of your mind.

Do it already, [Redacted -W].

<b><i>PS</i></b> Let me point out for the benefit of third persons that [Redacted -W] antipathy to me, passive-aggressive as it may be, is entirely justified. I used to be bemused by it myself, but then I found out we'd <a href="https://totheleftofcentre.wordpress.com/2013/01/04/1906/" rel="nofollow">met in a previous life, when [redacted -W] was TLOC</a>. Having re-read that thread I can't blame him for nursing a vendetta, not for one second.
