Martin Watson @ 8:
As a general rule, you can assume that any paper that is linked to at NoTricksZone wiil not say what NoTricksZone thinks it says. That site is pretty much a complete waste of time.

Martin Watson @ 5:
From a quick reading, there is nothing wrong with the information presented in the link you provide. It looks like an accurate discussion of what happens to the energy contained in an IR photon when it is absorbed by a greenhouse gas (CO2 or otherwise). That energy is almost always lost to other molecules (including non-greenhouse gases such as oxygen and nitrogen), and this leads to the heating of the atmosphere in general.
The article you link to also goes on to explain how higher temperatures in the atmosphere lead to more collisions with CO2 molecules (or other greenhouse gases), which will increase the rate at which they emit IR photons. And it explains how those are emitted in all directions, and how this leads to the greenhouse effect.
Just because very few absorbed photons lead directly to an immediate photon emission by CO2 does not mean that the energy is lost forever and the energy is not eventually emitted as a photon. The complete 100% of the absorbed photon energy is added to the atmosphere, and it continues to remain in the atmosphere until it is eventually emitted out to space or absorbed at the surface.
Eli Rabbet's blog has an excellent discussion of this same factor.
In other words, that article is an accurate description of exactly the process by which greenhouse gases such as CO2 lead to warming of the atmosphere. It provides nothing that represents a refutation of modern (the past 100+ years) of climate science. The article does not mean what the people are claiming it means.
If you are in a debate with someone making this argument, perhaps you can try asking them "what happens to the other 99.998% of the energy?" Or perhaps ask them "why are you referring to an article that accurately describes the greenhouse effect and how it causes warming, as if it refutes it?"

Hi Eclectic
Thanks for the reply.
Yes, it was another website making the claim that this research meant the effect of CO2 was infinitesimally small. I then tracked down the geoexpro as the original source of the info. I have to confess I didn't understand it!
This was the website where I first read it:

Martin Watson @5 ,
the absorption and re-emission of IR-photons by CO2 molecules is discussed in "Most Used Climate Myths" Number 74 ~ check the top left of (every) page on the SkepticalScience site. [Click on View All Arguments]
The energized CO2 molecules then then immediately transfer energy (kinetic) to neighbouring molecules (being mostly N2 and O2). Much the same thing happens with other GreenHouse Gas molecules e.g. of water molecules etc.
And N2 and O2 molecules transfer energy by impact to their neighbours ~ including to CO2 as well. All these impacts happening at a rate of billions per second.
Therefore, even though the IR-photon emission "percentage" is ultra-low for a particular molecule of CO2 or other GHGas . . . the billions of impacts produce an emission of a sea of photons per cubic millimeter of air.
Also, the geoexpro article you link to, goes into all this in a more detailed way.
Martin, I did not see that article make a suggestion that CO2 had an "infinitesimally small" global warming effect. Have I missed something ~ or were you confusing your memory with some other article elsewhere on the internet? It would be interesting to examine who or what was making the claim that CO2 (or H2O or other GHGasses) was inert . . . and was making a claim that GreenHouse-type global warming does not exist. Because such a claim goes against all the evidence gathered during the last 100+ years of investigation by physicists.

wilddouglascounty at 23:29 PM on 30 April 2024Pinning down climate change's role in extreme weather
Not to belabor it too much, but the relationship between climate change, the causes of climate change, and extreme weather is the same relationship as exists between a marathon runner's average running time, his use of steroids, and his best running time.
If a marathon runner's average time has been dropping over time since he began taking steroids, from 3 hours to 2 hours 50 minutes, and the next marathon he ran at 2 hours 35 minutes, or 15 minutes faster than his average. The real attribution of this change goes to his continuing steroid use, so it seems a bit wonky to attribute the fast run to his changing average.
This is what we are doing when we say that climate change CAUSED an extreme weather event. I think scientists need to be very clear when talking about causality, because linking the changing profiles of weather events to the changing average, or the changing climate, is confusing the causes with the measurements, which is not as clear as linking it to the increased amount of greenhouse gases in the atmosphere and oceans caused by human activities, with fossil fuel use near the top. This also clarifies the difference between the nature of the current changes in the climate we are experiencing and past climate fluctuations caused by other changes in our climate system: Milankovich cycle, volcanism, etc.

nigel @ 4:
I have to admit that I did not read the link to Bendell's web page before commenting on the portions you posted. Reading the link, I still don't like the way he refers to "elites" and such. What the heck is an "elite"? Although wiktionary includes a definition of "Someone who is among the best at a certain task", it also includes a definition of "A special group or social class of people which have a superior intellectual, social or economic status as the elite of society".
In the context of climate, economic, and social debates, the latter definition is probably closer to what is intended - but it also becomes a dog-whistle for "those uppity people that are trying to control us". The wiktionary definition uses the word "superior" - but that implies some sort of measurable scale by which the ability or status can be determined. If we consider "the elite" as people that have earned that status through demonstrated ability, then it's not a pejorative. In dog-whistle politics, the term "elite" has the implied meaning that the individual or group is unjustified in asserting any sort of superior position.
In that context, Bendell probably has some sort of point to make - but I think he has lost the battle by accepting the framing of the contrarians. The vagueness of the term "elite" works to their advantage - we may not know who "the elite" are, but we know they are Bad™. There is an innate resentment of that vague group, and framing the debate that way feeds the anger (to the advantage of the contrarians).
It used to be an argument of "but that's communism", and we now see "woke" being used in the same fashion. Apply a term everyone "knows" is Bad, and avoid actually making a concrete argument. It's not a new approach.
In reading Blendell's full post and his About page, I also see that he is not a climate scientist - and that some of his comments about contrarian arguments (e.g. climate models) demonstrates a lack of understanding why some of those contrarian arguments are wrong.

I am really hoping that somebody will be able to debunk the following claim in a way I can understand, or point me to an article which already does that. Yesterday, I was Googling about climate change and I came across a claim about CO2 and photons. Basically, it was saying that out of every 100,000 CO2 molecules which absorb a reflected IR photon from the surface, only 2 will actually re-emit that photon. Instead the other 99,998 molecuales will bump into a molecule of nitrogen or oxygen. And the claim was this means the contribution of CO2 to global warming was infinitesimally small. It seems to be referencing this article. Thanks.

Bob Loblow.
I agree entirely that the first paragraph was not well written. I almost didn't post it - but I felt it was needed for context and cutting bits out of it is tedious work.However it looks like hes just having a moan about mainstream media by suggesting The Guardian are far from perfect and also that its readers are allegdely unaware of the views of the current contrarians (which I would dispute). If you even just quickly scan the link its clear the writer is a bit of a media sceptic himself and also a bit suspicious of elites.
This is why I highlighted material in italics the second paragraph which seemed to summarise the main point of his article, which is the anti elite and anti globalisation agenda and how thats a convenient excuse to do nothing about the climate change. I think you seem to have got distracted by the other stuff.

nigel:
Reading that quote from Jem Blendell in comment #1, I can't tell if the first paragraph represents an argument against standard climate science, or an argument against the contrarian/denial viewpoint. It's not very well worded. In the second paragraph, it seems more clear that he thinks the contrarian viewpoint is not well supported.
When he talks about "the elites" and people being in the Guardian/BBC/CNN "bubble" and "the whole agenda on climate change", it certainly looks like he accepted some rather bogus arguments against climate science. Personally, don't accept climate science because of what I read in newspapers, web pages, or media outlets - I accept climate science from having learned it in university classes, teaching it in university, and reading the scientific literature and reports summarizing that literature such as the IPCC.
That final sentence in paragraph one finally reassures me that Jem Blendell has not drunk the contrarian koolaid, so the second paragraph is more palatable.
The unfortunate reality is that expecting the general public to become more scientifically-literate is a tough row to hoe. The tier-1 contrarians, who know they are peddling lies, know that emotional and bogus rhetoric wll convince a lot of people. There is the old variant of the old saying:
You can fool some of the people all of the time, and all of the people some of the time...
...and that's enough.
There is also the old Christian Science Monitor cartoon:
SkS used to have a web page that highlighted contradictions in "contrarian" viewpoints. Things such as "the temperature record is unreliable" while using the same temperature record to claim "no warming since 1998 2016". (The SkS page was taken down because it was too much work to maintain. There is an archived version here.)
The contrarian "science" is full of such contradictions. The ability to believe multiple contradictory viewpoints at the same time is a feature of compartmentalization.

Some commentary on a recent form of climate scepticism that I thought was interesting:
Prof Jem Bendell: When my book Breaking Together came out in May, some of my climate activist friends were surprised that I gave significant attention to rebutting scepticism on the existence of manmade climate change. I also surprised some of my colleagues at COP27 a year ago, when I gave a short talk on the rise of a new form of scepticism. That new form is couched in the important desire to resist oppression from greedy, hypocritical and unaccountable elites. I think the surprise of some that we still need to respond to climate scepticism reflects the bubble that many people working on environmental issues exist within. That’s a bubble of Western middle classes who believe they are well-informed, ethical and have some agency, despite relying on the Guardian, BBC or CNN for much of their news. Outside that bubble, there has been a rise in the belief that authorities and media misrepresent science to protect and profit themselves, while controlling the general public. That was primarily because of the experience of the pronouncements and policies during the early years of the pandemic. When people who are understandably resistant to that Covid orthodoxy have discovered the way elites have been using concern about climate change to enrich themselves, such as through the carbon credits scam, many have become suspicious of the whole agenda on climate change. Those of us who know some of the science on climate, and pay attention to recent temperatures and impacts, can feel incredulous at such scepticism. My green colleagues ask me: “How can someone deny what’s changing right before their very eyes?”
My correspondence with people expressing a new type of freedom-defending climate scepticism has led me to conclude that something else is needed than simply correcting their views with clear logic and evidence. My answers to the questions, which you can read below, may not have been perfect (he presents a list of climate myths and correct information similar to skepticalscience.com) . But the responses from sceptical people have sometimes seemed irrational. For instance, one type of response is an inconsistent switching between epistemologies (the fancy word for describing our view of how we come to know things about the world). That inconsistency involves sometimes claiming to reject all scholarship as untrustworthy instead to trust only firsthand experience. It is inconsistent because they ignore lots of firsthand experience contrary to their view, while also reaching for second hand and poorly referenced or debunked scholarship (often in the form of a blog or video clip) that might seem to support their view. Another irrational approach is the repetition of a claim that has already been debunked, which is the intellectual equivalent of raising one’s voice. One example is sending a blog or a video that repeats previously debunked claims. Another approach is to switch topic on to values and principles, while repeating false binaries given to them by the media. Specifically, that is the binary that climate change can’t be real because globalist elites are profiting from the issue and trying to control us. Instead, both the former and latter can be true at the same time (yep, quite elementary logic). Finally, the most widespread and pernicious irrationality is to regard these discussions as just one topic, and then choose criticism of the globalists as being the most important response, rather than understanding the situation of the natural environment and responding to it in a better way. That happens when people think “after all this debate, I’m not sure about climate change but I’m certain about resisting the globalists, so I’ll focus on that.” If one’s motivation for inquiring into public affairs is to feel like a moral agentic person and experience a burst of energy from belonging to the good guys in a fight, then such a conclusion is seductive. That is especially because it requires no painful recognition of the ecological tragedy, no sacrifices, no risk taking, no changing of lifestyles, and no complicated participation in community projects. It also generates easy likes on social media from people similarly addicted to narratives that avoid difficult self-reflection and change. Unfortunately, the result of this irrationality is people don’t begin to prepare emotionally and practically for what has already started unfolding around them.

( I don't entirely agree with the writers own tendency towards criticism of globalism and elites, and of the mainstream authorities motives, and of the idea of covid lockdown policies, but I thought he makes some good points on other issues as above)

Bob Loblaw at 05:28 AM on 26 April 2024Climate - the Movie: a hot mess of (c)old myths!
The similarities of climate and Covid (or other) denial psychology are indeed of interest, and sort of loosely on-topic, but let's try to not get into details Covid discussions.
For the psychology aspect, I have several times referred to the web site The Authoritarians. There is a long ebook there, plus a few other blog posts as follow-ups. It discusses the learnings of a social psychology prof that spent a career looking at what he called "authoritarian followers". That is to say, he was more focused on the psychology and behaviour of the people that follow authoritarians - not the authority figures themselves (although that is also discussed).
Sadly the most recent note on that web page is the announcement that the author - Bob Altemeyer - had passed away. Eclectic's note that Dan Kahneman had passed away was something I had read about in my local paper.
As for the sequence of "denial" thought patterns, it has been long discussed that the sequence often goes along these lines:
- It's not happening
- It's not us
- It's not bad
- It's too late, and why didn't you warn us?
Philippe's comment about "a matter of when, not if" regarding Covid extends to my experience. As a grade school student, I learned that the Spanish Flu had killed more people than the first world war, and there was concern it could happen again. Any post-Covid cries of "we never expected this" seemed rather hollow - given I learned about it in grade school.
In a similar vein, on a weather-related topic, I remember watching a cable news channel reporter interviewing a local police official on the US east cost, a few days before a hurricane was expected to hit. (This was in the early days of TV sending reporters into the middle of disasters before they happened.)
- The reporter asked "How long have you been preparing for this hurricane?"
- The official said "25 years."
- He continued by pointing out that they lived in an area prone to hurricanes. You don't wait until one is in the forecast before you decide how to deal with it. You know that you are eventually going to need those plans.
We can see previous commenters on this thread that firmly believe that action is not warranted until after harm has happened.

Eclectic at 04:14 AM on 26 April 2024Climate - the Movie: a hot mess of (c)old myths!
It would be interesting to see an intensive study of the overlap in mentality of Climate-Deniers and Anti-Vaxxers and Flat-Earthers. All three groups show a rigid delusional thinking, which has (thus far) proved to be impervious to rational discussion/education.
But delusions & other irrationality of thinking woud be a hard topic to study well ~ and possibly it would be somewhat unethical to spend the effort & money in studying such intransigent minds.
# Note : The prominent psychologist, Prof. Daniel Kahneman (author of "Thinking, Fast and Slow") is known for his studies of the "kinks" in the human mind. His death at age 90, was announced last month.

Philippe Chantreau at 02:39 AM on 26 April 2024Climate - the Movie: a hot mess of (c)old myths!
Indeed, it would be inappropriate to launch the C subject here, although the conspiratorial thinking aspect is shared with many other efforts of organized denial found in other subjects. I personally have very little patience for it, after working in the ICU throughout a crisis that anyone who ever had a microbiology class knew was not a matter of if but a matter of when. It may be the only one I see in my lifetime but certainly won't be the last.

One Planet Only Forever @27
I am with you on this issue. I am currently trying to present such points in the best way to inspire deniers to change on a channel where somebody posted this film which garnered some positive resonance. As an environmentalist, vegan activist who studied ecology and human ecology in which, in 1992 we delved into the idea of man-made climate change at a time where it was generally seen as a laughing stock, I wanted to chime in with some relevant points:
The channel I am referring to is actually more Covid centred. I find myself in the fairly unusual position of being very pro consensus science in the field of environment, whereas I find medical science is riddled with corruption, mistruths and effective lobbyism which came to a head with Covid together with coercion at a level where it is entirely rational to assume plausibility of at least some conspiratorial aspects. Plenty of evidence is there.
I am mentioning this partly because you touched on the topic but more importantly because I believe it is important to understand the psychology of climate deniers in a more nuanced manner, i.e. in more depth. Unfortunately, as far as I understand it, many people with legitimate concerns regarding Covid measures, associated discrimination and other significant costs to society, got drawn in to certain (predictably) politically motivated groups and for whatever reason, emotional triggers, legitimate lack of trust in the system for some aspects, lack of time for the reviewing the details (big one) etc, have just fallen for climate denial propaganda.
This is at least one part of the spectrum of the climate denial "group" which theoretically could be won back to rationality and trust in the areas of science where trust is actually deserved.
It may be that more emotional people are attracted to these traps. The more we can refine our understanding of the psychology of transformation, the better chance we have of inspiring rationality and deserved trust. Unfortunately, simply facts normally doesn't do it very well. So we have to get creative as scientific mindsets who are characteristically not so emotional on average. It's very important for people to sense they have been heard and taken seriously, even if we strongly disagree with their perceptions and belief systems.
In short we need to apply kindness and compassion even when we feel like throwing that out of the window and slamming people for being ignorant et cetera. An invitation to follow the money could be useful, like you pointed to. Funding and wages in science it's a very variable thing depending upon the type of science. Environmental science is probably on average at the lowest end a financial return, compared with "science" that largely comes straight out of industries, wishing to make profits on their products.
I'm not going to hammer out my evidence for the C topic because my comment will most likely be deleted. I am new here so don't know how this works yet but if you really are interested I will (somewhat begrudgingly) spend even more of my free time to lay it out in a private message ;) otherwise we may have to just agree to disagree.

MA Rodger at 19:42 PM on 25 April 2024At a glance - Is the CO2 effect saturated?
Eclectic @14,
You say the work of these jokers Kubicki, Kopczyński & Młyńczak failed the WUWT test, being too bonkers even for Anthony Willard Watts to cope-with. I would say Watts has happily promoted work just as bonkers in the past.
And as you say, there is no WUWT coverage of this Kubicki et al 2024 paper although Google shows it is mentioned once in one of the comment threads, as is an earlier paper from the same jokers. Indeed, there are two such earlier papers from 2020 and 2022. Thankfully, these are relatively brief and thus they easily expose the main error these jokers are promoting.
In Kubicki et al (2020) they kick-off by misusing the Schwarzschild equation. The error they employ even gets a mention within this Wiki-ref which says:-
At equilibrium, dIλ = 0 even when the density of the GHG (n) increases. This has led some to falsely believe that Schwarzschild's equation predicts no radiative forcing at wavelengths where absorption is "saturated".
They then measure the radiation from the Moon through a chamber either filled with air or with CO2 and show there is no difference and thus, as their misuse of Schwarzschild suggests, that the Earth's CO2 is "saturated." In preparing for this grand experiment, they research the thermal properties of the Moon as an IR source and thus tell us:-
The moon. The temperature of its surface varies a lot, but for the part illuminated by the Sun, according to encyclopaedic information, it may slightly exceed 1100ºC.
This well demonstrates that these jokers are on a different planet to us as it is well know our Moon only manages 120ºC under the equatorial noon-day sun.

Eclectic at 01:29 AM on 25 April 2024At a glance - Is the CO2 effect saturated?
Thanks for that, MA Rodger @13.
Possibly - just possibly - the ultimate Thumbs-Down on the Kubicki et al. paper . . . is that it has not been trumpeted at WUWT website (which usually trumpets any crackpot paper which seems "anti-mainstream" science. And that's despite many of the WUWT denizens regularly/continually asserting that the CO2-GreenHoouse Effect was now irrelevant (because "saturated") or was always non-valid anyway.
Now perhaps I have failed to remember "Kubicki" being a Nine-Day Wonder at WUWT ~ or perhaps I failed to notice "Kubicki" among the mountainous garbage-pile accumulating at WUWT. But as a final check, I used the WUWT Search Function . . . and turned up Nothing.
Something of Contrarian pretensions would need to be pretty bad, not to get 15-minutes of fame at WUWT. But maybe I speak too soon?

MA Rodger at 00:15 AM on 25 April 2024At a glance - Is the CO2 effect saturated?
The paper Kubicki et al (2024) 'Climatic consequences of the process of saturation of radiation absorption in gases' is utter garbage from start to finish. When something is so bad, it is a big job setting straight the error-on-error presented.
As an exemplar of the level of nonsense, consider the opening paragraph, sentence by sentence.
Due to the overlap of the absorption spectra of certain atmospheric gases and vapours with a portion of the thermal radiation spectrum from the Earth's surface, these gases absorb the mentioned radiation.
I'd assume this is saying that the atmosphere contains gases (or "vapours" if you are pre-Victorian) which absorb certain IR wavelengths emitted by the Earth's surface. Calling this "overlap" is very odd.
This leads to an increase in their temperature and the re-emission of radiation in all directions, including towards the Earth.
The absorption if IR does lead to "an increase in their temperature" but the emission from atmospheric gases is determined by its temperature. Absorbed IR only very rarely results in a re-emission of IR (and if it does, the IR energy is not cause "increase in their temperature").
As a result, with an increase in the concentration of the radiation-absorbing gas, the temperature of the Earth's surface rises.
This is not how the greenhouse effect works. For wavelengths longer than the limit for its temperature defined by 'black body' physicis (for the Earth, about 4 microns), the planet emits IR across the entire spectrum. The level of emission depends on the temperature of the point of emission which for wavelengths where greenhouse gases operate is not the surface but up in the atmosphere. For IR in the 15 micron band, CO2 will result in emissions to space from up in the atmosphere where it is colder and thus where emissions are less. If adding CO2 moves the height of emission up into a colder altitude, emissions will fall and the Earth then has to heat up to regain thermal equilibrium.
Due to the observed continuous increase in the average temperature of the Earth and the simultaneous increase in the concentration of carbon dioxide in the atmosphere, it has been recognized that the increase in atmospheric carbon dioxide concentration associated with human activity may be the cause of climate warming.
This was perhaps true before the 1950s but the absorption/emission of IR by various gasses was identified and measured when the USAF began to develop IR air-to-air missiles. The warming-effect of a doubling of CO2 (a radiative forcing of +3.7Wm^-2) has been established for decades.
So just like debating science with nextdoor's cat, taking the heed the whitterings of Messers Kubicki, Kopczyński & Młyńczak is a big big waste of time.

Thanks Bob - and all of you - for taking the time to answer me. I'm just one of many lay people trying to raise the awareness, and we don't always have sufficient science training to be sure of our ground, so it's very helpful when you engage, without too much impatience!

Bob Loblaw at 23:43 PM on 23 April 2024At a glance - Is the CO2 effect saturated?
Theo:
Taking a quick look at that paper, I see it refers to Angstrom's work in 1900 to support their "saturation" argument. This is already discussed in the Advanced tab of the detailed "Is the CO2 effect saturated?" post that this at-a-glance introduces. Short version - we've learned a few things since Angstrom wrote his paper in 1900.
Searching the recent paper for "saturation", it seems that they are using the typical fake skeptic approach that applies the Beer-Lambert law (which is exponential in nature, and a standard part of radiation transfer theory) to the atmosphere as a whole. That is - they look at whether or not IR radiation can make it through the atmosphere in a single pass.
To nobody's surprise, this turns out to not be the case - IR radiation in the bands absorbed by CO2 rarely makes it directly from the earth's surface to space. The energy in the photons needs to go through a series of absorption/re-emission cycles as it gradually works its way up through the atmosphere. When these processes are included in the calculations, it turns out that this particular flavour of the "saturation" argument falls flat on its face, and adding more CO2 (compared to our current levels) does indeed have an effect.
Executive Summary: the authors of that paper have no idea how the greenhouse effect works, as Eclectic has stated.
Read the full rebuttal here for more discussion - and the details of the Beer-Lambert Law are also discussed in this SkS blog post.
Elsevier is usually considered a reputable publisher, but they screwed up on this one. The rapid passage from "received" to "accepted" is indeed a red flag. The journal - Applications in Engineering Science - is clearly an off-topic journal for this paper. On the page I link to, it mentions "time to first decision" as 42 days, and "review time" of 94 days. If you click on "View all insights", you get to this page that also gives "Submission to acceptance" as 77 days, and "acceptance to publication" as five days. The seven days for this paper (from "received" to "accepted") is, shall we say, a bit shorter than usual?
It is worth noting that several other papers in the same issue also have very short times between "received" and "accepted". Of the four I looked at, none of them had any indication that the authors were asked to revise anything, which is rather unusual. Someone at that journal is in a rush.
(If you click on "What do these dates mean?", below the title/author section of the web page for the appear, it specifically states that "received" is the date of the original submission, and they will say "revised" if a more recent version is submitted - e.g. after review.)

Addendum:
Theo Simon @7 and earlier :-
I should have mentioned that, if you still have a nagging doubt and wonder if Kubicki et al. have really made an astounding breakthrough ~ then the easy course for you is to put your feet up and relax and observe for 6 or 7 months.
Because in October or November this year (2024) the Nobel Committee will maybe be announcing Kubicki & colleagues have won the Nobel Prize in Physics. If that were to happen . . . then all over the world, the enjoyers of scrambled eggs would celebrate a collapse in the price of their favorite egg-dish . . . as a million physicists wipe all the egg off their own faces. And the name Kubicki will rival the fame of Einstein ! (Excuse my flippancy.)

Theo Simon @7 :
Theo, please don't waste your time (or anyone's) in going through the details of that Kubicki paper.
It is just like when you encounter someone's submitted "paper" showing (with an avalanche of complex mathematics & diagrams) why his design for a Perpetual Motion Machine is certain to work beautifully, as soon as he gets finance to build it. You yourself know that there must be one or more errors buried away in the midst of his presentation ~ but why would you bother to search? Life is too short and precious, to spend time dissecting some crackpot ideas which have already been proven to be fundamentally flawed. Proven and re-proven to be garbage.
NoTricksZone is a cynical recycler of nonsenses, to get clicks & profits ~ and happily recycles any garbage which the climate-science denialists themselves keep recycling at intervals. But I admit to some interest in the psychology of how & why some people with science degrees, even professorships - usually Emeritus types - manage to delude themselves in various ways. Yes, they are often misreported . . . and yet they seem mostly motivated by rather extremist political views and are handicapped by their own Motivated Reasoning.

Thanks, I did notice that it was taking a position, which I took as a red flag. But I struggled to understand if it was making new claims regarding saturation, based on new experimental evidence, or if the explanations on this page essentially cover it already.
I'd be very interested to know how valid this papers arguments are and if they have been rebuffed, or found wanting in peer review, as I think this line of attack will be a very popular one in the coming months. I've already met it from numerous trolls elsewhere who currently think it's their "gotcha!"

Theo Simon @4 :
As John Mason says @5 , there are certainly some Red Flags attached to that Kubicki paper ~ including it's citations of papers by Harde; by Humlum; and by Idso . . . those prominent luminati of the Alternate Universe.
Theo, to save your reading time in future ~ whenever you see a "gotcha" article in NoTricksZone .com , claiming that the mainstream science (of anything) is quite wrong . . . then there's a roughly 99% probability that the article is a load of taurine excrement [abbreviation = BS ].
Reading the cited [Kubicki] article's Abstract quickly demonstrates that the authors have simply failed to understand the basic physics of the atmosphere & GreenHouse Effect [abbreviation = GHE ]. And this first impression gets confirmed by reading the article's Conclusions, which are comprised of an excessive amount of word salad and bizarro politics.
Kubicki et al. seem to have discovered ideas that have been well & truly debunked . . . many decades ago. If only the authors had troubled to have their "novel" ideas reviewed by experts, before presenting their paper to the world ! They could have saved themselves so much embarrassment, as well as saving dollars.

John Mason at 16:53 PM on 23 April 2024At a glance - Is the CO2 effect saturated?
re - # 4: I've just taken a look at that paper. The reason we didn't mention it was that it came out very recently.
This however is part of the conclusion:
"However, the intention of the authors of this article is not to encourage anyone to degrade the natural environment. Coal and petroleum are valuable chemical resources, and due to their finite reserves, they should be utilized sparingly to ensure they last for future generations. Furthermore, intensive coal mining directly contributes to environmental degradation (land drainage, landscape alteration, tectonic movements). It should also be considered that frequently used outdated heating systems burning coal and outdated internal combustion engines fueled by petroleum products emit many toxic substances (which have nothing to do with CO2). Therefore, it seems that efforts towards renewable energy sources should be intensified, but unsubstantiated arguments, especially those that hinder economic development, should not be used for this purpose."
In scientific literature, a conclusion should be about the work that was done, and not an arm-waving diatribe! The Introduction likewise gives its first 400 plus words over to arm-wavy waffle about the IPCC. I'm surprised it got beyond peer review on that basis. Indeed, its submission/acceptance dates (Received 4 December 2023, Accepted 11 December 2023) suggests it never was reviewed. In most cases a period of months divides those two dates because the peer review process is quite slow. These are all warning signs that 'something is up' with this item.

I am not science trained but trying to understand. This rebuttal doesn't mention the alleged evidence presented in the paper "Climatic consequences of the process of saturation of radiation absorption in gases" by Kubicki and others - or does it? The current denialism talking point is that additional CO2 has now been shown to have no additional warming effect, and claims new proofs of this:

Absurd indeed. The IEA has said that the clean energy transition would save the world $71 trillion by 2050. The cost would be $44 trillion, but $115 trillion in fuel savings.
So it's worth doing even without climate change costs. -
nigelj at 06:56 AM on 22 April 20242024 SkS Weekly Climate Change & Global Warming News Roundup #16
Regarding the story of the week: "Wednesday's study from the Potsdam Institute for Climate Impact Research (PIK), which is backed by the German government, stands out for the severity of its findings. It calculates climate change will shave 17% off the global economy's GDP by the middle of the century." Now compare this with the DICE economic model (Richard Nordhaus) : "The updated results imply a 1.6% GDP- equivalent loss at 3 °C warming over preindustrial temperatures, up from 1.2% in the review for DICE- 2016.19 Mar 2."
The time frames of the two studies look approximately the same. 3 degrees warming would be about mid century. The difference in estimated damages between reducing gdp by 17% compared to 1.6% looks absolutely huge.
You cant reconcile this easily. This has me puzzled so I'm hoping I haven't misinterpreted something. However the DICE model has been heavily criticised by several experts as seriously underestimating the costs of climate change and being an absurd study in its handling of risk assessments.

Spooky @899 , you should not really be surprised ~ since the OP article is referring to Global temperature changes.
Not to the local rapid changes in the boreal icesheet region (e.g. Denmark, Greenland, Alaska : during the last glacial age) as shown in the Bolling-Allerod warming and in the briefer Dansgaard-Oeschger events. Those local northern regions are affected by "sudden" changes in local oceanic currents ~ both smaller & larger (e.g. the AMOC). But that has little effect on the global scale, except when it involves a massive event like the melting of the Laurentide Ice Sheet (i.e. the Younger Dryas).
In India, the Indian Monsoons (to which you allude) show much fluctuation resulting from very small alterations in local temperatures & winds (winds which may bring more oxygen18-rich water) . . . even in the absence of a 30-year climate change.
For global temperature changes, there need to be global-scale changes in albedo / insolation / particulates / or greenhouse gasses.
-
Spooky at 01:33 AM on 21 April 2024Climate's changed before
I am surprised that the rapid temperature increase which happened about 15'000 years ago during Bolling-Allerod period is not mentionned. Records indicate a 3C warming in less than 90 years, and therefore was way faster than current warming. Those records are specific to the gulf of Alaska and do not prove by themselves that the warming was global. However brutal variations of Delta18 ratio have also been observed in Greenland and India at the same peiod (I have not checked if it was at the exact same time). I would be interested by comments of experts about this. Thank you.

Paul Pukite at 01:19 AM on 20 April 2024How extreme was the Earth's temperature in 2023
nigelj said: "El ninos release ocean heat that has been building up"
The complement to this is that La Ninas absorb atmospheric heat as the cold thermocline approaches the surface, thus exposing a large area heat sink. Thus, a complete swing is -cold to +hot.
So the fact that we have been in a La Nina state the prior few years makes the warming spike even more stark.
Also the AMO shows a significant El Nino-like peak. This is perhaps expected, as the precursor to this situation occurred in 1878 (see chart below) when one of the largest El Ninos recorded occurred in the Pacific, while a similar scaled peak occurred in the Atlantic's AMO.

-
Jan at 17:45 PM on 19 April 2024How extreme was the Earth's temperature in 2023
Made it a little bit nicer, as it is important:
On the causes of the exceptional temperature jump in 2023
First things first:
What was special about the warming in 2023 was, that it happened all in the last 6 months, so it was a much larger jump over these months than the mean values of 2023.
Further, only a moderate El Nino existed, so not too much warming came from here.
Reasons where:
SOx reductions over the shipping routes amplified the marine heatwave signal across the mid-latitudes.
The El Nino in combination with a positive Indian Dipole - both lead to a larger heat release of the tropical oceans as a clear and strong circulation cell is supported over the tropical oceans due to the zonal SSTs gradient.
Sea ice reductions around the Antarctic caused circulation changes that led to moist and warm air advection over Antarctica (strong effect on the warming as exceptional heat waves rocked Antarctica), as well as radiative effects of the sea ice reductions and heat release over sea ice-free areas.
Then that climate warming warms the oceans now more than natural variability is often able to produce colder than normal SSTs - at one time only some ocean regions existed with colder than normal temperatures.
Then we had the vast expansion of marine heatwaves across the global oceans, especially across the mid-latitudes reaching a coverage of more than 40% in July.
The warmer-than-normal Oceans created a cloud feedback thereby increasing shortwave absorption (reinforces marine heatwaves).
From 2012 to 2016 we had a non-linear increase of moisture in the marine boundary layer caused by exceptional SSTs. The next jump will have happened in 2023 causing a water vapor feedback over large parts of the oceans to increase. And tropical moist air advection is causing marine heatwaves in the subtropics to mid-latitudes. So also here is another feedback as more water vapor radiates longwave radiation back to the surface.
Further, we had during summer to autumn large areas where the soil-moisture-temperature cascade came into play producing these exceptional continental heat waves. It comes along with a cloud feedback and supports stalled/fixed high-pressure systems as these heat domes redirect the jet around them (higher troposphere).
Then we had the pattern effect of increasing zonal (east/west direction) temperature gradients at the ocean surface and continents which disturb the overlying circulation, often causing blocking patterns (also a reason for the marine heatwaves to build up)
Then we had towards autumn a heat release of the marine heatwaves across the mid-latitudes, as the atmosphere gets colder. Also, cold core and warm cors eddies cause extreme temperature gradients in the western boundary extension regions leading to a larger latent heat releases over these ocean regions (small-scale pattern effect of SSTs increases wind speeds).
Last it has been possible that the oceans released heat from the subsurface that had built up. Across the mid-latitudes warm freshening water masses are accumulating under the surface as shallow as 150m depth. And these heat depots could have been tapped, as the jets speed up during winter, as the density gradient between the tropics and poles increases in the upper atmosphere while it decreases near the surface, especially during winter. More and stronger low-pressure systems due to increased shear are the outcome. And all these extreme low-pressure systems in autumn and winter across the mid-latitudes in 2023/24 could have tapped these subsurface heat depots. But no study here as this is a new development seen in the intensity of the low-pressure systems the last years (e.g. number of atmospheric rivers hitting the US west coast)
Main problem thou is the expansion of marine heatwaves, as they are feedback driven by global warming heating the oceans from the surface too fast (thermal stratification increases non-linear in the upper 300m of the oceans in various regions), in combination with the pattern effect which disturbs global zonal circulation with the result of more stalled high-pressure systems (low wind speeds are in most instances the main precondition for marine heatwaves to form besides thermal stratification and shallow upper mixed layer depth).
Last the warming of the northern latitudes can also be included in the factors driving global warming in 2023.
In short, the warming of 2023 was feedback-driven by various systems forcing each other into a heating mode with the systems of the oceans, atmosphere, and landmasses acting in unison!
The exact series of which contributed to what extent to the heating science has to find out. But it would have to be done on a monthly basis!
The next jump will have devastating consequences as they become larger...
In my opinion, the model spread is now a joke as it is way too large proving the uselessness of models as they will increasingly become unable to predict what is coming as too many parametrizations prevent them from simulating the non-linear character of the mutually reinforcing systems with many processes operating on small scales...
p.s. we warm the oceans too fast from the surface that is our main problem!

nigelj at 07:08 AM on 18 April 2024How extreme was the Earth's temperature in 2023
Some explanations for the unusual global warming levels in 2023:
James Hansen thinks the anomalously high global surface temperature in 2023 are due to AGW + El Nino + Aerosols reductions. I can't find the related commentary, and have to go by memory, but Hansen suggests that the quite abrupt reductions in shipping aerosols in 2023 added to reductions in industrial aerosols over the last ten years warmed the oceans and this energy comes out after a time delay and it all came out in 2023. Perhaps someone has the details of his suggestion and comments on its credibility.
El ninos release ocean heat that has been building up. I note that the high sea surface temperatures are in the northern oceans are away from the centre of el nino activity.
From NASA: Five Factors to Explain the Record Heat in 2023. But what caused 2023, especially the second half of it, to be so hot? Scientists asked themselves this same question. Here is a breakdown of primary factors that scientists considered to explain the record-breaking heat ( I have cut and pasted the key statements only):
The long-term rise in greenhouse gases is the primary driver.
The return of El Niño added to the heat.
Globally, long-term ocean warming and hotter-than-normal sea surface temperatures played a part.
Aerosols are decreasing, so they are no longer slowing the rise in temperatures.
Scientists found that the Hunga Tonga-Hunga Ha‘apai volcanic eruption did not substantially add to the record heat.earthobservatory.nasa.gov/images/152313/five-factors-to-explain-the-record-heat-in-2023
From PBS News: ‘We’re frankly astonished.’ Why 2023’s record-breaking heat surprised scientists. A range of factors including general warming due to human-caused climate change, the El Niño climate pattern, record-low Antarctic sea ice and others — contributed to 2023’s record-breaking heat, but they don’t tell the full story. Schmidt said more work has to be done to fully understand why the year was so hot.
“In 2024, we’ll be seeing whether this persists or whether it kind of goes back to a normal pattern,” he said. “And that will be kind of telling as to whether 2023 was just a very unusual combination of things that all added up to what we saw, or whether there’s something systematically different going forward.” (Seems like good comments to me)
From Copernicus:
Some alternative suggestions on 2023 warming including changes in regional wind patterns over the northern parts of the oceans bringing heat to the surface:
atmosphere.copernicus.eu/aerosols-are-so2-emissions-reductions-contributing-global-warming
(This is not a reference to el nino, but to other changes in wind patterns to the north. For me it raises the question of caused the changes in wind patterns)
Clearly there is no definitive answer yet on why 2023 was so unusually warm ( ditto 2024 thus far). As scientists say next years data will help illuminate the causes.

William,I have been away.
The risk is : we try and transition aways from fossil fuels without a better alternative - all previous significant energy changes have occurred naturally - when we have had a better alternative.
I don't think you have provided any evidence that alternative energy systems are not a better alternative. Especially when considering all factors like climate change, health impacts of pollutions, etc
One day we likely will have a better cheaper alternative to fossil fuels - at the moment we don't . Renewables cannot replace fossil fuels they are too unreliable and expensive ,Constantly repeating this does not make it true. You have been provided with peer-reviewed evidence to the contrary. The Lazard analysis of levelized energy costs is putting unsubsidized wind+storage and solar+storage ahead of all but fully depreciated FF stations.
Fossil fuels have brought untold benefits.
I don't dispute this for a second, but I fail to see why it is relevant. FF are now doing a great deal of harm and we have alternatives. We don't "owe" FF any loyalty for past benefits. That would be absurb.What puzzles me is why you obviously dont believe peer-reviewed analysis of alternatives but instead opt for what seems to me to be either uninformed opinion or worse, FF propoganda. You seem to be deeply commited to the status quo, and trying to find arguments to defend that. Why do you think that is and how do go about evaluating competing claims?

And yes, the WUWT blogsite does have its points : (a) It is very, very active as a website, both in articles per day, and in 100's of comments per day. True, the articles are selective & slanted as outrage-stimulating propaganda . . . and the comments are highly repetitious venting. But interspersed with a few useful comments (by a handful of real scientists who enjoy tweaking the Denialists' noses).
~(b) WUWT is a slanted mirror, enabling the viewer outside to gaze over the parapets of the Deniosphere ~ and into the Bedlam that lies within. The denizens there are not insane [per legal definition] . . . but most are intellectually & morally insane. Arguably, they are psychiatrically insane too.
~(c) Possibly . . . and arguably . . . WUWT is a "good thing", for it acts as a flame to attract & amuse the climate nutter/moths of the Anglosphere, and give them a feeling that they are being "active" in their cause.
Sid , the SkS site is very much the opposite (of WUWT ) : it is a small site, run by volunteers, and provides only a few comments per day ~ but provides a wealth of easily-accessible climate science information for those who wish to educate themselves. So the site cannot be expected to be the "mover & shaker" on the world scene (such as a President like yourself would desire).

Thank you. You are doubtless correct but the scientist in you should scream that what matters is what people actually do not what they say (evidence not stated opinion).
At least one major branch of economics (which some would like to call a "science") would insist that the "price mechanism" in a free market economy cannot be bettered (that does not at all mean that it is error free!).
Re: This blog's policy on Politics would seem to allow some political/economic discourse on this thread's topic. The "Movie" seems to me to be (unfortunately) very much about politics.
Democracy, by which I mean one person one (SECRET) vote, can at times produce perverse outcomes as often as not as a result of campaigns of misinformation (such as "Climate: The Movie"). It behoves scientists (and the media) to produce effective counters. This site goes a long way towards that but how far does it actually reach and can it be bettered?

Plymouth Sid @104 : you are certainly correct in your scientific assessment.
IMHO, the "climate problem" is like a coin ~ one side is the mainstream science; the other side is the politics of How & When to take action against the problem.
The science side is very straightforward ~ and only a handful of genuinely well-qualified scientists are nay-sayers or doubt-mongers (and even these, on closer examination, are often guilty of speaking out of both sides of their mouth).
The politics side ~ is a hot mess of denial, sloth & inertia, and short-term self interest. Of which we are all guilty to a greater or lesser extent. Plus, we need better technology too, to fully replace fossil fuels.
On SkS here, I occasionally rant against the notorious WUWT website (a website I view frequently, to experience some laughs . . . and some Schadenfreude). WUWT shows both sides of the coin continually ~ the participants there are largely in denial of the realities of climate science . . . and at the same time they exhibit a political extremism brimming with anger, selfishness, and uncharitableness. WUWT is a very toxic site : and the participants love "Climate - The Movie" and seem oblivious to its many severe flaws.

Plymouth Sid:
The choices that humans make can be guided by science, but those choices also include values that are not really amenable to scientific examination. You can use science to study people's choices, and associate the choices they make with other measurable items, but values are hard to measure. (You can record what people say about their values, or you can assign "value" labels to their actions or words, but there is a degree of subjectivity about individual behaviour.)
As for politics: that also can be guided by science - but often it is not. Here at Skeptical Science, we try to avoid purely political discussions - but there are times when political issues do connect with climate science. The Comments Policy states this as follows:
No politics. Rants about politics, religion, faith, ideology or one world governments will be deleted. Occasional blogposts on Skeptical Science touch on issues intimately related to politics. For those posts this rule may be relaxed, but only if explicitly stated at the end of the blogpost.
