The Greenhouse Defect

The most disruptive site on climate science

In one of the last articles I investigated the “radiative flux” (sic!) concept. With it, although I am afraid it is based on really bad logic, it is at least possible to reproduce the canonical CO2 forcing estimate of some 3.7W/m2. However even this theoretical approach is no remedy for a (primary-) water vapor (WV) feedback of some 1.8W/m2. There is simply no way to get even close to this figure. Even if you push all the limits, you will get no higher than 1.2W/m2. I mean it will be a lot lower anyway, as WV is vastly overrated as a GHG.

 

The situation is odd enough, given radiative…

Ok, this is a little issue I ran into and I really wanted to source it out, rather than having it bloating up another article, while not properly addressing it. If you look up the literature, like the famous Kiehl, Trenberth papers, or Wikipedia, you will get a straight forward answer. The atmospheric window is about 40W/m2 in size, and of course it is all settled science.

 

In reality the settled rather means consensus, and consensus means the abolishment of all scientific principles like pluralism and criticism to promote an all too important message. Just digging a little deeper reveals,…

Sorry for being silent here for way too long. I guess I just took on a bad habit of starting articles and not finishing them. Partly this is because I like to go into depth before making a statement, partly it is because “climate science” is just a target rich environment. There are so many absurd stories worth to be told, which strangely enough were never covered. I can only emphasize again what a miserable job the “critical side” is doing. Anyway..

 

Michael Mann’s famous (or rather infamous) hockey stick has been talked about a lot. He was brave enough to “hide the decline” in tree ring…

I have written a couple of articles investigating climate sensitivity and asserted it was almost negligible. Well, since “negligible” is a circumstantial term, let me be more precise. Based on line-by-line calculations and some necessary corrections to what are identifiable mistakes in the orthodox approach, I did end up with a figure of around 0.5K only. That would allow for CO2 forcing and WV feedback, though not for other feedbacks like cloud- and albedo-. These however, even when considered in orthodox magnitudes, would barely affect the outcome.

 

All these calculations were implicitly…

Last year, when Gavin Schmidt explained the CO2 problem in six easy steps on the realclimate blog, I could not help to hint towards the surface emissivity problem. You know, while the consensus largely assumes an emissivity of unity, it is rather about 0.91 in reality. This blunder alone produces a chain reaction of more severe consequences, like overstating the GHE, getting the attribution wrong, overstating climate sensitivity and messing up climate models in a way that no super computer will ever fix.

 

Gavin was so kind to respond: “Not really sure why you think this, but LW emissivity…

It is funny how the content of this largely ignored site sometimes diffuses into the world. Of course such education is its scope, but one might expect people to communicate a little more open on what their source is, or ask for clarification if the content is too complex for them. After all this would help to spread the word and gain me some well deserved reputation.

 

Bob Irvine’s misunderstanding

 

Just a few days ago I had a little déjà-vu while reading an article on WUWT. The title was “The Climate Feedback Debate”, sounding interesting to me. After a couple of paraphrases I could not…

Aerosols, although poorly understood, play a vital role in climate models. If you ask why global warming only really started in the 1970s, aerosols are the answer. If you wonder how the only moderate warming witnessed so far shall support high climate sensitivity, again aerosols are the answer. So it is about time we take a closer look at them.

 

Aerosols and Volcanos

 

It is true, aerosols can cool the planet. In fact declining (surface-) temperatures have been observed many times over after volcanic eruptions. In the course of an eruption, lots of hot gases, most importantly sulfur, get…

I do not know why, but „Climate Science“ seems to be cursed to get everything wrong, even if it is completely pointless. It puts me into an awkward position to sort out all these side shows, when there is a far more significant main line. Yet you can not really skip it, since sooner or later it would haunt you anyway. What can I say..

 

The Polar Amplification, what does it mean? It is pretty simple, the poles tend to heat, or cool respectively, much stronger than the rest of the planet. Something makes the climate there specifically sensitive. When we are talking about ice ages and…

I know focusing on contrails as the main cause for global warming may look a bit strange to most people. Are they not reflecting sun light? Should that not be cooling the planet? And even in the scientific literature, although by now it is consensus new they have some warming momentum, this was quite disputed for a long time. However, if you understand the basic physics of the GHE correctly, and there is a lot of confusion out there, then contrails are a logical subject of interest.

 

As with any component of the atmosphere, there are two sides to be considered. That is a) the SW- and b) the…

As we have discussed GHGs and clouds are overlapped all over the place. “Climate science” largely ignores this and the logical implications to it. Moreover however, GHGs overlap themselves so to say. It is for this reason, that a doubling of CO2 will not double its radiative forcing, but will only cause a gradual increase. Some people call this “saturation”, suggesting CO2 and other GHGs would hardly enhance the GHE with additional quantities. While this is essentially true, there is no innovation in it, as the orthodoxy claims nothing else.

Although the title may be a bit misleading, as some minor feedbacks actually do exist, they do not play the role “climate science” wants to make us believe. There is very straight forward logical evidence denying the basic claim and to my knowledge, it has not been discussed so far. Also this shall be a synopsis of my previous work with an argument Lord Monckton tries to rightfully bring forward.

When it comes to alternative explanations for “global warming”, most climate skeptics are inclined to point to the sun. It makes sense in a way, as the GHE is responsible for a certain deviation in surface temperature, while the sun is responsible for the bulk of it. Without the sun, if Earth was a rogue planet, the surface temperature would be close to zero Kelvin. So in a way the sun is the gorilla in the room, and it would be foolish to ignore it when it comes to natural climate change. Also we know the sun is prone to cycles, though because of the infancy of civilization and modern day…

After exploring the relevant pieces finally has come the time to put them all together. I have dealt with a number of mistakes, all having pivotal impacts on ECS estimates. Oddly enough, all these mistakes produce biases in the same direction, that is overheating the planet due to CO2 emissions. To provide an oversight let me recapitulate the main points.

 

The Lambda Mistake

 

Lambda, as a conversion factor of radiative forcing or feedback to temperature, is assumed to be 0.3. The figure is derived from the assumption a surface at 288K would emit 240W/m2 into space, as 1 / (((289/288)^4 -…

The “lapse rate feedback” is the other component of vapor feedback, and it is negative by nature. In order get a comprehensive understanding of vapor feedback as whole and ECS estimates, we need to explore it. The orthodoxy seems not just to lack an understanding of its magnitude, but also of its nature.

 

As discussed in the first part of this article the radiative effect of a 6.5% increment of vapor will only result in 0.5W/m2 forcing, rather than common estimates of 1.5-2W/m2. Forcing? Yes, if we would assume an endogenous increase in vapor that would be a forcing, if we assume an…

The inclined reader of this site may have recognized things go a bit different here. To those who think to know “climate science” it may look like alien technology. I do not give much on opinions, not even my own. Neither I like to ask questions I can not answer. Rather I enjoy some narcissist pleasure over exploring and providing answers, simply because I can. You know greyhounds need to run, geniuses need to solve. It is the most natural thing. For sure “climate science” requires some deep penetrating, laser sharp analysis as opposed to some dilettante theory building, or “polar bears are…

As an undisputed basic fact of climate science, vapor is the most significant GHG, providing a strong feedback to any (exogenous) forcing. Regrettably this “fact” is utter nonsense and it only has been undisputed because no one had the brain to get it right. Let us change this for good.

 

I have dealt with this issue before, yet in order to discuss vapor feedback, we should have a deeper look on it. And I must admit in the course of doing so, it provided me with some interesting insights I did not expect. Let us first recall what Gavin Schmidt says about the GHE of vapor, since it pretty much…

In this article I am going to analyze CO2 forcing estimates, put them into perspective, account for the major flaws there, and finally produce an accurate estimate. It is quite a significant achievement I would think, as for the first time in the history of “climate science” this kernel of climate modelling will be done correctly. Brace for impact!

 

It is one of the most profound questions of climate science. What is the ECS (equilibrium climate sensitivity) for any delta in CO2. Practically this term is commonly used on a doubling of CO2 concentration in the atmosphere, though it could be…

Ok, this is a purely theoretical article and probably it could not get any more boring than this. Also it should be totally unnecessary to even explain such a basic logic. One could make it a simple question within an IQ test, so at least the article will be short. Yet on the other side there are two reasons making it totally necessary to explain. First of all, most people fail on some IQ test questions, which is the reason why not everyone has at least some 145 IQ, a minimum requirement to do science I would say. Also having many unqualified scientists will not be compensated by…

The fun has not yet ended, we will continue discuss “greenhouse defects”, yet the time has come to turn serious, dead serious on the subject of ECS estimates. Insights have consequences, and all the mistakes “climate science” has made with the GHE do translate into ill-fated climate projections. No supercomputer in this world can fix stupid, and so we are going to learn how climate projections are magnitudes off, as they are all rotten in their core. Take this as an introduction.

There is nothing exciting here to be revealed, just a few notable details to round up our understanding of the physics. If you should ever look up the GHE of CO2 you would need to be very lucky to find any consistent answer. For instance wikipedia will tell you CO2 contributes 9-26% to the GHE, as.. “It is not possible to assign a specific percentage to each gas because the absorption and emission bands of the gases overlap.. Clouds also absorb and emit infrared radiation and thus affect the radiative properties of the atmosphere”
