Greenhouse effect has been falsified

The term greenhouse effect is a slight misnomer, in the sense that physical greenhouses warm via a different mechanism. The greenhouse effect as an atmospheric mechanism functions through radiative heat loss, while a traditional greenhouse as a built structure blocks convective heat loss. Two different things, same name. When the very terms of scientific study are confusing and ill defined, some flags are raised.

There's no empirical evidence

198 topics and none of them directly address the problem of particulate pollution. Anyone that has been to a number of big cities has noticed the large problem of air pollution by particulates.

Particles in the atmosphere cause scattering of incoming radiation, so the amount of solar radiation that impact the earth's surface is affected, either incoming or outgoing. This means that higher elevations receive more solar radiation including ultraviolet or UV radiation. So why doesn't greater exposure to solar radiation result in higher air temperatures with elevation? The answer is that very little of the atmosphere is heated directly by absorbing solar radiation. As any chemist will explain to you, air is mostly vacuum, void. Instead, most incoming solar radiation is either scattered in the atmosphere or passes through it and is absorbed by the earth. This is why the ground is often warmer than the air surrounding it.

Therefore, what warms the air, is the direct contact with the ground and liquid surface of the ocean, the interface. Solar radiation (e.g. light) will pass through the air.

Temperatures decrease with distance from the earth's surface.

So another factor to be considered is the absorbtion of solar energy by the earth's surface that is clearly changing (in color, material composition, etc) by human activity and natural activity.

CO2 is not the only driver of climate

I will rephrase my question:

Where is the proof that CO2 is driving the climate change (via greenhouse effect) and CO2 variation is not an effect of other variables, like solar energy. Please post the evidence that proofs undeniably this supposed fact. Correlation does not mean causation.

Where is the proof that CO2 rising levels in the atmosphere is causing increasing global surface temperature? Don't give me general comments like its all over this website, or all over IPCC reports, please point to me to the exact evidence, the definite and exact published scientific reasearch paper, who is the author, when was it published, in what journal, and so on.

CO2 is not the only driver of climate

gzzm2013 @60,

I am curious as to what you actually mean by describing CO2 as either "driving the climate" or being "a third exogenous variable."

Beyond than you ask for 'undeniable proof' of 'causation'.
While, as the response indicates, there is s great deal of evidence to show this "causation", perhaps the simplest "proof" is the IR spectrum of Earth's cooling system. The big bite out of the spectrum at Wavenumber 666 is "undeniably" due to CO2 and thus "undeniably" the direct cause of a quarter of the planet's greenhouse effect and this being so is also "undeniably" the driver of the other three-quarters.

Eclectic at 16:19 PM on 24 January 2021

CO2 is not the only driver of climate

Gzzm @60 ,

the evidence regarding CO2 ~ is to be found in the latest IPCC report, and also in many other places such as the websites of the learned scientific societies (e.g. American Academy of Sciences, the U.K. Royal Society). They all give the same basic information for you, yet you will find the most detail at the IPCC.

Since you seem to be starting from scratch, and it will take some hours of instruction, you should not ask Tom to spoonfeed you.

Gzzm @1282 ,

thank you for replying to Tom Dayton, who, I gather, was inclined to bet that you yourself were simply one of those "timid-but-angry" commenters who make a drive-by comment . . . and are never seen again here, owing to their strange psychological make-up.

Gzzm, clearly you are made of sterner stuff and wish to add some rational intelligent points to the online discourse. And it's never too late to begin in earnest !

In reply to your point /4. [in brief because off-topic] :-

4. Where is the proof ... CO2 ... variable like solar energy ...

Alas, Gzzm, this is "off-topic" here at this thread. You will find the evidence you ask for, at the Top Left of this page, via MOST USED Climate Myths number 2 "it's the sun" . . . or the other thread recommended by the Moderator. Indeed, your education would be greatly enhanced by you reading through at least the first half-dozen Myths in their Original Post form [basic thru advanced ] . And as has already been suggested, please read the OP of this thread here (which you appear to have omitted from your things-to-do-first list.)

Back on topic, Gzzm, with the models are unreliable ~ I can recommend some later reading for you, for the counter-arguments which can be found on the WattsUpWithThat blogsite. At WUWT the view is that all the scientists' models have subsequently proven to be completely wrong . . . and therefore all climate science is wrong.

Gzzm, you may not have heard of WUWT , or perhaps you have been warned to avoid it because of its strong tendency to promote half-baked science (or disproven science) and even more to repeatedly promote rubbish which is "Not Even Wrong". But fear not, Gzzm ~ among the pig-swill there, you may occasionally find a pearl or two from genuine scientists like Nick Stokes. Alas, Stokes does not appear there often . . . likewise there are a few other scientific minds to be found in the WUWT comments columns, but few and rare, because they generally get driven out of WUWT by the editors/censors. (Or perhaps these scientific minds get tired of the incessant torrents of mindless vitriol they receive at WUWT .)

Nevertheless, Gzzm, the WUWT blogsite is a fascinating exhibition of logical fallacies and intellectual insanity. An excellent guide to What Not To Do with one's brain. Most interesting of all, is the huge amount of anger there, underlying the flakey thinking and political extremism and lack of human compassion.

Gzzm, I have the strong impression that you yourself may be able to enlighten me about the deepest psychiatric basis of the sheer anger in these disparate "contrarian" minds. Some of it may be a genetic personality-type anger in all or most of the denialists, but there may well be one or more other factors. Your own insight would be welcome ! (But please reply on a more appropriate thread.)

2 and 3. So let's put it this simply, let us draw an analogy. Many so called sciences like economics claim that they have economic "models" , which model complex systems, but the fact remains that the economics science is not able to predict the next global financial crisis in magnitude or timing or nature.

Yet people are claiming that the climatic models are reliable and can actually predict future climate (but long term trends only). I would like to hear from the best model, you chose it, name it, locate it, say who programmed it, who maintains it, who financed it (the onus is on the claimant, not me) and say what is the sea level (however they define it) in year 2025, 2030, 2035, 2040, and so on until year 5000. Also change in global temperature (however they define it, give the formal unchanging definition). We of course don't know what the sun is going to do, or volcanoes. So the prediction is contigent of factors that are unforeseable, so the predictions are a function of different combinations and series and progressions of multivariable values. I want to see the data. Should not be hard for a proven theory, right?

1. So you are saying that because those models are to be run on expensive computers they cannot be accessed by the general public. Why can't the public enter the input to the model, send it to the operators, then get the output of the model? Is the public not paying for the models? Every model has inputs and outputs. Its that simple. Can you list what are the input parameters of the best model? And what are its output parameters? Are the models too busy with experts entering inputs on them all the time that there is no time for the public to use what they paid for? Can things not be explained in plain English? Someone very smart said that if you can't explain it to a 6 year old you don't understand it yourself.

In his Politics, Aristotle believed man was a "political animal" because he is a social creature with the power of speech and moral reasoning: Hence it is evident that the state is a creation of nature, and that man is by nature a political animal.

To think that the IPCC is not political is naive at best. The United Nations Security council is formed by the victors of WW2, nations that have been colonial empires and empires. They are great exporters of weapons and they have financed the United Nations.

You cannot analyze the science of climate change without questioning its funding, motives, mechanisms, governance and who is not sitting at the table, and who is not represented.

It's waste heat

Climate Detective from elsewhere, [link URL not being uploaded https://skepticalscience.com//news.php?n=4962#136555 ]

Forgive me for demonstrating the major fallacies within your grand work but as you say "The calculations are not difficult to do."

The assertion you make that "All energy generation by humans results in an output of heat or thermal energy" is fundamentally wrong. It is "power" that is generated and when this is through the application of kinetic energy from passing fluids, through the burning of recently grown plant matter or from intercepting solar energy that would otherwise be absorbed by the ground, there is not net increase of the planet's surface energy. It is only the absorbing of albedo-decreasing solar energy, the splitting of heavy atoms or the burning of fossil fuels to release chemical energy that does result increased the planet's surface energy.
Further your attempts to suggest a significant level of climatic warming in an area such as the UK is due to these increases in surface energy ignores what would be the absence of such warming in adjacent areas where there is effectively no such surface warming, like the North Sea, the North Atlantic or for that matter, the whole of Africa. Taken over the whole globe, the UK is exceptional as it uses ~1% of global primary power but within ~0.05% of the global surface area. Because, as with all small areas of the globe, UK temperatures are very much dictated by the adjacent climate, the global average is the relevant value and that is trivially small. (Generally the energy released by FF use is exceeded by the GHG effect of the CO2 thus released in 9 to 18 months, depending on the type of FF employed.)

nigelj @4

The calculations are not difficult to do. I have done them here and here.

What Dr. S. Jeevananda Reddy appears to be saying in comment @1 (if I understand correctly) is that even renewable energy use will increase global temperatures. This is obviously true. All energy use ends up as heat and entropy, i.e. temperature. The second law of thermodynamics tells us that.

The relevant question is, by how much does this energy use increase local temperatures? The answer is, that in advanced economies with high population densities current levels of energy use can increase temperatures by more than 1 °C since pre-industrial times, and this will only get worse with more population growth and economic growth. Even the average suburban housing estate will heat the local environment by over 1 °C (see here). More importantly, this has nothing to do with CO2 and the greenhouse effect. It applies equally to all energy sources, but obviously CO2 will make it even worse via radiative forcing or feedback.

The point is, green energy is not a free lunch. Therefore zero carbon emissions is not a panacea either.

Philippe @31 ,

Greetings. And no offense taken by me. For anyone interested in the science of climate science, the WUWT blog is indeed an almost complete waste of time.

However, as a student of human nature, I must say that WUWT illustrates some of the human response to the challenges of AGW ~ and in that connection WUWT is a marvellous microcosm of mental pathologies. And being somewhat of a gentleman of leisure myself (sadly, far more a bourgeois gentilhomme than a true gentilhomme ) it is easy for me to find time to indulge my hobby there. Also helps me to keep some practised ripostes at the ready, against Denialists.

But I must not deflect further from this thread's topic. Despite the WUWT attractions of the ridiculous Christopher Monckton and the slightly less ridiculous Andy May, Willis Eschenbach, et alia. And despite the "peanut gallery" as you call it ~ a gallery rich in old chestnuts as well as peanut ideations, and even including some Brazil nuts (well, one or two from Chile or Argentina actually, as expatriate Yankees).

So I had better get off my hobbyhorse, and return the thread to its main topic, which seems to be the good Doctor Reddy.

Moderator Response:

[BL] Actually, the topic here is discussion of the various items posted in the digest.

2021 SkS Weekly Climate Change & Global Warming Digest #1

DSJR,

I will not comment on your quality or ethics, as I really have no interest in it. This is not about you, or me, but helping readers form understanding. I reiterate that the framing of your argument on satellite data suggests nefarious intent, although you provided no substantiation of such intent. Perhaps you don't see that and it's a language issue.

There is on this site abundant discussion of satellite data, including the repeated shortcomings of the UAH team, who had to have others show major mistakes on at least 2 occasions. There are also detailed posts on the height of the "slices" where the measurements are taken from which temperatures are derived. Go hack at it there. Perhaps this is about other satellite data than the ones we are most familiar with, then more references are needed, so we can check for ourselves. Usually, when corrections are done, papers about the why and how of the corrections are published.

As for the idea that solar and wind power plants have any measurable effect at a global scale on surface temperatures, I'll say that what you provided falls short by so much that, under the current state of knowledge, it puts that hypothesis in the "not even wrong" category. However, my opinion is always open to modifications in the face of new findings. If the idea attracts research and it turns it had merit, I will acknowledge that. However, as of now, I don't see that we are anywhere close to have the weight of evidence necessary.

Don't take it personally. Once again, this is not about you.

2021 SkS Weekly Climate Change & Global Warming Digest #1

Thank you for the compliment, Eclectic, and no offense was intended. I know it is necessary to monitor the crazyness of the denialist crowd, I just don't ever find that I couldn't do something better with my time. I've been at this long enough to have fond memories of Steven Goddard and the carbonic snow in Antarctica :-)

Nowadays, Watts is a little more careful to weed out whoppers of such magnitude. But then, there was BEST, and the NOAA studies that completely invalidated the basic argument for the very existence of the site, and eventually Watts'own results that did exactly the same thing, all met with anger (toward BEST) and more denial.

The attitude of the WUWT peanut gallery when faced with reality taught me everything I needed to know about these clowns. Not to mention, of course, the "outing" of private addresses of scientists whose work they disliked, predating methods that have unfortunately become more common.

Philippe Chantreau at 04:26 AM on 15 January 2021

2021 SkS Weekly Climate Change & Global Warming Digest #1

Bob, to elaborate, I'll repost this here, where it is even more relelvant than on the wildfire thread:

NOAA has just put out an assessment of the costs of climate change related extreme events over the past few decades. The steady increase in the yearly number of events and the yearly costs is staggering. The acceleration is interesting: the 2010s saw 119 events, of which 50 occured inthe past 3 years. Although 2020 ranked 1st with 22 events (probably due to the hurricane season), that's an average of 11.9 events per year, almost double the rate of the 2000s (6.2 per year).

Meanwhile, the subsidies to fossil fuels are not exactly slowing down.

The economic argument is making less and less sense, and the adverse effects of climate change are no longer some diffuse problem diluted in a somewhat distant future. It's here, now, slapping us in the face once a month.

Today (01-14-21) Politico (an online news organization) posted an article claiming that major banks and insurers want to start sending more money to address the climate crisis. Apparently they want a promenent seat at the table during the Biden administration.

While the proposals described in the Politico article do not go as far as many climate activists would like, it seems to me that it is a hopeful sign that financial institutions are talking about the climate crisis.

This carbon brief article claims that models used by the IPCC severely underestimate the damages currently caused by climate change. Apparently the IPCC models try to estimate general damages from climate change and assume extreme weather events cause little damage since they are rare. If fact, extreme weather events currently cause billions of dollars and a large part of that damage is attributable to climate change. For example hurricanes have long existed but Hurricane Harvey did more damage from increased rain due to climate change.

If insurers become concerned that they are losing money from climate change the pressure to take significant action will increase dramatically. Even 5 years ago financial institutions were mostly silent about climate change. Hopefully this will result in significant action being taken. I am interested in what other SkS readers think about this topic.

Your claim that language is not relevant to science is mistaken. Not only language is crucial for communication between members of science teams, but also for communicating science findings, whether that would be to a specialized audience or the general public.

Ok sorry I misinterpreted your comment. But please note that breathing is carbon neutral. Refer below:

skepticalscience.com/breathing-co2-carbon-dioxide.htm

It should also be understood that while the growing human population potentially burns more fosssil fuels, etc, population growth is generally slowing down in most places, and even falling in absolute terms in some countries like Japan. We could perhaps make it slow down faster, but there are limits to what can be achieved with policies that would be generally acceptable to people. So our main focus has to be on things like a new energy grid. Hopefully any educated person can understand that, its simple enough.

Dr. S. Jeevananda Reddy @16,

♥ Indeed, your book Reddy, S.J., (2008) 'Climate Change: Myths & Realities' is mostly available to read on a Google Books preview up to page 87 but pages 88-193 "are not shown in this preview".

♥ And nobody would mistake the critique within the 'blog' by William Connolley as your work.

♥ As for your assertion that my use of the adjective "erroneous" is not backed up by science, that is yet more "erroneous" input from you.
I haven't read past your comment @6 but that yields conclusive findings for me.
Your suggestions that solar or wind power are contributing to global warming is plain silly. A wind farm mixes air, and actually extracts energy locally to be transported for use elewhere. Temperature increases are simply the result of mixing of air, not the generating of warming.
A solar farm will decrease albedo but the additional solar energy absorbed is comparable to the waste heat from a fossil-fuelled or nuclear powerplant. And this is without the CO2 from a fossil-fuelled powerpalnt which will add to AGW.

Any positive climate forcing raises global temperature and this in turn will be amplified by feedbacks, particularly through the resulting higher specific humidity.
Thus you write condescendingly @6: "increased CO2 raises temperature slightly and that produces an increase in water vapour, which does have the capability of raising atmospheric temperature" but with the added comment "However, it is not the case." So how is it that a climate forcing from increased CO2 (at 3.7wm^-2 per doubling) does not increase global temperature and thus initiate further warming from feedbacks? What scientific principle could you invoke to argue such a thing?

DRSJReddy ,

Thank you for your extensive information about yourself.

Evidently you are a serious and important person.

But to use the modern English colloquialism : "Enough already!"

Speaking for readers here, I can say it would be much appreciated if you now began at the various topic threads [see post #5 moderation listing] and clearly addressed those aspects of mainstream climate science which you consider to be incorrect. Of course, specifying your supporting scientific evidence (as may exist in the peer-reviewed articles of reputable scientific journals).

Moderator Response:

[BL] Dr. Reddy will be monitored closely - as will this entire thread - so please everyone: leave the moderation to the moderators. In particular, if egregious violations of the comments policy are seen, wait before responding. The next stage of moderation will be deletions of all or part of comments, not just warnings.

You used the word used by WUwt — in science whether English is first language or second is immeterial. My first two articles published in international journal in 1970. My 10 articles were published in international reputed peer reviewed journal in 1983/84.

Let me present three examples:

1. At TROPMET conference scientists analysed the satellite data and presented their results. The satellite data was provided by Ahmedabad institute – a scientist from Ahmedabad got up and said the data is not accurate. Then I asked him, if so why did you supply such data? or why you did not inform those scientists? There was no answer. Same was the case with satellite global average temperature data series. I presented this data on the global average surface temperature data series – around 1980 to 2000 in 2008 in my book. Later this data series disappeared from internet and appeared new data series saying that previous data series are not correct. Both satellite and surface data series by different groups present different values. Why?
2. When I was a scientist with ICRISAT, my group [two other scientist] tried to test A&M Texas Sorghum Growth model for India. They experimental data for Indian locations and few other countries and tested the model by adjusting radiation component. They presented the results at a meeting Chaired by DG of ICRISAT [a former soil professor from Hawaii] and Arkin from Texas who developed the model was also present. The result showed poor correlation for grain and biomass. Then the chairman/DG asked me you test the model by replacing the soil water balance model used in the model with my model [ICSWAB]. With this they presented the result on the next day. The correlation improved from around 0.30 to 0.85. But Arkin refused to change his model. Stopped the work. Then they brought in Monteith’s model from UK. This also failed. In fact the soil water balance model used in Arkin model works under conserved soil moisture which was the case where he developed but in India the model should account rainfall with crop and soil parameters. This is simple science and not English.
3. I submitted a paper to an international journal. They sent to two reviewers. One made few observations and accepted for publication. The other made good comments but said “the data can be fitted to linear curve”. Based on this observation, the regional editor rejected the paper for publication. Then I wrote to the Editor-in-Chief a 100 latter questioning the integrity of editorial committee members. This was sent to three regional editors [Australia, UK & USA], who concurred with my views. Then the Editor-in-Chief asked me to divide it in to three articles [articles related to editorial committee members of that journal]. They were published under discussion/comments on the articles I referred. After this, Editor-in-Chief asked me to resubmit the paper rejected. I did not do that but included in my 1993 book – as the reviewer used same statement which I used in the case of his article in Agronomy Journal/USA. IMD Journal is one of reputed journal — I published several articles during 70-80s, referred to date.

Humans breath Air and use Oxygen and release CO2.

CO2 contribution to global warming, present equation that showed the relation — in fact what you all are talking is not global warming but it is trend that relates to all human induced contributions — see the definition of climate change by IPCC/UNFCCC/WMO. ----

"So, the information obviously just does not exist — a false observation. This shows you decided something you don't accept others version and make cheap statements like "rant" ."

Oh the information exists does it? Please show me where, with a copy and paste and a link. You havent so far depite repeated requests. Whether it exists or not you are making certain claims, so the onus is on you to provide specific evidence, which you are totally unable to do.

And rant. Pfttt. I apply the term to my own writing sometimes. Its not derogatory. Rubbish would be impolite although arguably very accurate.

"The whole talk on CO2 — you plot CO2 versus population from 1960 to date present a simple linear trend."

Correlation doesn't prove causation. What are you a doctor of, out of curiosity? Astrology? I bet its another question you wont answer directly.

DSJR,

It seems English may not be your first language, and it makes your post somewhat difficult to sort through. It is not mine either but most of my secondary education took place in English so I have no difficulty in understanding, speaking, reading and writing.

Let's clarify a few things. I did not say anything about your afiliations, I have no real interest in it. However, you should acknowledge that this site routinely refers to peer-reviewed work published in high impact journals and that they do carry more weight. I note that, among the multiple citations in your most lengthy post, the majority are to yourself. You are arguing the quantification of attribution, and other things, without referring to the major works of the major contributors in the field who do publish in high impact journals, but by referring mostly to yourself. My skepticism is not unwarranted.

Secondly, I do not "want" you to do anything. I reserve the right to gauge the usefulness of your contribution.

From the starting of my research carrier, I am not associated with any organization and institution as you said. You can see from my publications, all is my own work as an individual. After returning to India from my assignments with FAO & WMO, I brought out a book in 1993 based on my work up to that time [based on articles published in national and international journals and my Ph.D. Thesis, ANU, Canberra]. The book review was published in an international journal by Chairman of Agrometeorology Group in WMO at that time. [Also edited TROPMET symposium held in 1995 at space science centre — published in 1999 titled "Advanced Technologies in Meteorology --.] This is a reference book for Agrometeorology at post-graduate level. On the request of a publisher I revised it and it was published in 2019.

I participated in Dot Earth discussions in New York Times until it was closed. During these sessions one commentator asked me whether I know Prof. Jagdish Shula. I replied to her saying we both worked in Pune met services – I was in IMD and he was in IITM. Now, you raised that I am from Wuwt but I stopped participating in this. In fact the article published in watts up with that [wuwt] as guest article, I in fact presented it as invited talk at a national conference on 7th December 2013. Since long I am not participating in wuwt. I concentrated publishing four books and arounsd 20 articles on online journals – all on request. Also presenting invited/Keynote presentations at institutions in Hyderabad/India as I stopped travelling outside Hyderabad. Also actively participating on environmental issues in Hyderabad.

All you say is that you want me follow you leaving science path. Sorry I don't do that.

[BL] Accusing everyone else of not understanding how science is done is not a good start to your participation here.
