Bob Loblaw at 23:22 PM on 2 July 2023Increasing CO2 has little to no effect
Yes, manuel2001nyc, there are some major things missing in the questions you pose in comment #444.
I'll start by trying to address questions 1 and 2 that Rob Honeycutt skips over, but I'll need to explain a bit of background, first.
To begin, your description of "saturation" suggests that you think of CO2 as a reservoir of energy that gradually fills up to the point that it can't hold any more. This is not the case.
- Individual molecules can only store energy at certain levels, dictated by their molecular structure. Electrons "jump" from one energy level to another, absorbing or releasing energy in specific quanta as they "jump". Encyclopedia Britannica has a nice explanation.
- When the absorption or release of energy occurs via radiation, the photons absorbed or released must have a wavelength that matches the energy quanta - photon energy is uniquely linked to wavelength.
- This link between molecular structure, energy levels, and photon energy explain why molecules such as CO2 only absorb and emit certain wavelengths or radiation.
So, for question 1, yes CO2 absorbs and emits at the same wavelengths. And it does not matter whether the IR radiation came from other CO2 molecules or the earth's surface, etc. A 14um photon is just a 14um photon, with no memory of where it came from.
As for question 2: the term "saturation" makes no sense in this context. Individual molecules do not get "saturated". When they absorb a photon, their energy level increases. They very rapidly pass this energy on to any other gas molecules (CO2 or anything else) they collide with. This will increase the energy levels of those molecules. This will raise the overall average temperature of the air.
- Note that "temperature" is not a property of individual molecules. It is the average kinetic energy of a very large number of molecules. Temperature will "average out" because those molecules are always colliding with each other and sharing energy.
- Sometimes, when a molecule such as CO2 obtains energy from a collision with another molecule, it will shed that energy by emitting a photon instead of colliding with a different molecule.
- The warmer the air, the more often a CO2 molecule will obtain extra energy via collision, and the more often it will emit a photon. This is how temperature affects total radiation energy emission - by emitting more photons, not by emitting more energy in each photon.
For additional information on the process of absorption and emission, you might benefit from reading this post here at Skeptical Science. In particular, some of the comments talk more about emission. (The original post is more about absorption.)

I have become so cynical towards a real global response to reducing our still increasing global greenhouse gases. Climate will only respond to action-the talks, studies and asessments and tools are nice, positive affirming to read but when your up against this www.youtube.com/watch?v=7ApjSrB6E1c it's no surprise the enfolding biosphere collapse with us included is inevitable.

One Planet Only Forever at 07:46 AM on 2 July 2023Wildfires are not caused by global warming
PollutionMonster @9,
Regarding 'attribution of Canada's current wildfires to human caused climate change', the following Carbon Brief article may help you: "Media reaction: Canada’s wildfires in 2023 and the role of climate change"
The article states that:
"No attribution studies have so far made a climate connection with the ongoing wildfires in Canada.
But previous studies have looked at the link between climate change and other extreme weather events. One study found that climate change made a 2020 Siberian heatwave at least 600 times more likely. This heat broke temperature records and led to wildfires.
Additionally, the IPCC said that wildland fire has been “identified as a top climate-change risk facing Canada”.
The interactive map below displays a 2020 review of scientific studies finding that climate change is increasing the risk of wildfires globally."
The bolded words in the quote are links to additional information in the article. Read the article to access those links. And read the entire article. It includes additional information you may find helpful in your attempts to help others learn to better understand this issue.

Rob Honeycutt at 03:05 AM on 2 July 2023Increasing CO2 has little to no effect
manuel2001nyc... You've got quite a mishmash of errors embedded into all of your questions here. It seems quite a mess to untangle, but here are a few of examples:
"...absortiom / IR (14/16) emission) by a molecule of CO2 from IR comming from the sun(day)..."
Incoming energy from the sun is higher frequency and does not interact with CO2.
Your questions 1 and 2 are completely indecipherable to me. Maybe others understand what you're trying to get at.
"...it seems termal IR emitted by the sun overpass IR emmitted by the Earth. is this right?"
Here again, you're not understanding that incoming energy is not primarily in the IR spectrum. There is some short wave IR but it doesn't have a lot of effect. CO2 interacts with LWIR (long wave IR).
Your question 4 is also hard to decipher but also seems to contradict your own statement in question 2.
"someone has made calculations on how much themal IR (earth surace) and how much IR from sun is absorved by CO2?"
Same problem here. Incoming energy is in the short wave frequencies, primarily in the visible light spectrum.
Here's a diagram that may help you:
"6) as CO2 accounts for 0.035% how we can explain their impact in global warning?"
Simple answer, yes. This question has been repeatedly asked and answered essentially the same way for well over 150 years.

Eclectic at 23:31 PM on 1 July 2023Increasing CO2 has little to no effect
Manuel2001nyc @444 ,
The IR thermal energy absorbed by a CO2 molecule is very quickly passed (by impact) to nearby N2 and O2 molecules. N2 and O2 molecules can give vibrational energy to a CO2 molecule ~ which may then emit a 15-micron IR photon . . . or more probably instead pass vibrational energy back to N2 or O2 molecules. All this happens over and over again ~ many times per second. Similar processes happen with H2O and other Greenhouse gasses.
Therefore "saturation" is unimportant near the Earth's surface ~ but becomes important at very high altitudes in the atmosphere.
Your 6 questions are far too few for an education in the physics. You first need to do much reading to understand the complex mechanisms of radiation entering and leaving the planet.

manuel2001nyc at 20:57 PM on 1 July 2023Increasing CO2 has little to no effect
thank you all for your post, I fully support respectfull debate as a way to create your own opinion. I relly concern about global warning and the future of our planet and as technologist i belive that make the right question leads you to the right asnwer. I read a lot about global warning and its consequences nevertherless i am not an expert. Thus, an after reading here posts from 2001. I reached (learnt) a basic conclusion: the key concept is balance between the ratios( IR(14-16um) absortiom / IR (14/16) emission) by a molecule of CO2 from IR comming from the sun(day) and from the earth surface(night) also considering CO2 saturation . right?
I kindly rise these questions:
1) IS the IR range the same for absortion/emission (14-16)? what happen with the termal radiation between 8um-14um also emtitted by the earth surface?
2) Saturated CO2 is not able to absorve but it emits during 12 hours aprox? how much time does a C02 molecula to be satured? I guess is close to 0 seconds, right?
3) even most of the IR from the sun are under 3um, it seems that there is low percentage in the termal range (8-16un), but considering the global IR emmitted by the sun, it seems termal IR emitted by the sun overpass IR emmitted by the Earth. is this right?
4) A satured CO2 emits energy a very low pace, right? if we consider it is exposed during the day to sunlight and during the night to the thermal IR. When CO2 emits energy?
5) someone has made calculations on how much themal IR (earth surace) and how much IR from sun is absorved by CO2?
6) as CO2 accounts for 0.035% how we can explain their impact in global warning?
thank you in advance for all your asnwers.

Bob Loblaw at 10:58 AM on 30 June 2023The Dynamics of The Green Plate Effect
The bucket analogy does relate to the greenhouse effect in terms of reducing the rate of loss, which requires an adjustment of the bucket level. The reason the bucket reaches a new equilibrium is that as the water level rises, the pressure increases (a linear function of the height of water above the hole), and that increased pressure succeeds in forcing enough water through the smaller hole. We need to remember that there is a pressure term that drives the flow.
The increased pressure in the bucket is an analogy to the increased surface temperature creating a larger temperature difference between the surface and the ubiquitous 255K emitting IR to space in the greenhouse effect.
On the other hand, the Green Plate effect is intended as a specific counterargument to the "cold object can't cause a warm object to heat up" myth. It does not need any reference to the greenhouse effect at all to demonstrate that this "cold object/warm object" myth about the 2nd law is wrong.
If the "cold object/warm object violates 2nd law" argument was correct, then the argument would have to show an error in the Green Plate scenario. If any hard-core denier want to continue with that argument here, they are going to have to do it without any reference to the greenhouse effect. If they can't "disprove" the Green Plate effect, then there is no way that they will be able to apply the [lack of] logic to the more complex greenhouse effect.
-
Rob Honeycutt at 01:57 AM on 30 June 2023The Dynamics of The Green Plate Effect
The green plate analogy is the most fun to argue with hard core climate deniers. It's amusing to watch all the contortions they go through to avoid understanding the concept. You end up with energy appearing and disappearing everytime they say something.
I had one guy insisting that energy actually does disappear because of superposition when a photon is received by a warmer object. (sigh)
-
Evan at 00:47 AM on 30 June 2023The Dynamics of The Green Plate Effect
Eclectic@2, although there may be "one ring to rule them all", I don't think there is ever one analogy that works for all. My hope is not to muddy the waters, but rather to provide a different analogy in case the Green Plate analogy does not work for some people.
-
Evan at 00:45 AM on 30 June 2023The Dynamics of The Green Plate Effect
I should have added that with the smaller hole the flow rate is reduced at the point the size of the hole is reduced. Once equilibrium is reestablished, the flow rate out of the bucket is the same as it was for the larger hole, at equilibrium. But to achieve the same flow rate with the smaller hole as for the larger hole, the water level in the bucket must rise.
-
Eclectic at 00:43 AM on 30 June 2023The Dynamics of The Green Plate Effect
Evan @1 , the "bucket and hole" analogy seems (to me) to be even more distant a connection to "Greenhouse Effect" than is the Green Plate . . . and will start still more argument & confusion among newcomers.
-
Evan at 23:23 PM on 29 June 2023The Dynamics of The Green Plate Effect
Nice post Bob.
Another way to view this is that greenhouse gases cause warming by reducing the energy lost to space. They are not generating energy, they are merely reducing the rate of loss of energy to outer space, which allows the atmospheric temperature to rise.
Much like a bucket with a hole in it being filled by a garden hose. The flow into the bucket balances the flow out of the hole, maintaining a constant height of water at equilibrium. Reduce the size of the hole, and the flow rate of water out of the bucket decreases, allowing the water level to rise. The smaller hole is not filling the bucket, it is merely reducing the water lost from the bucket.

michael sweet at 23:08 PM on 29 June 2023Gas stoves are even worse for our health than previously known, new study finds
David-acct:
The study titled " Population Attributable Fraction of Gas Stoves and Childhood Asthma in the United States" primarily looks at the United States and attributes 13% of childhood asthma to gas stoves. The study you cited titled "Cooking fuels and prevalence of asthma: a global analysis of
phase three of the International Study of Asthma and
Allergies in Childhood" (free copy of the whole paper) looks primarily at open fires and is worldwide. The selection criteria for the United States study included the term "gas" in the title. Your curiosity about why a worldwide study primarily about open fires was not used in a USA study about gas stoves is completely misplaced.Both studies point out that much more work has been done in developed countries concerning the effect of gas stoves on public health. Since much more work has been done in developed countries on the hazards of gas stoves it stands to reason that the conclusions of those studies are on firmer scientific grounds.
In the study discussed in this OP titled "Gas and Propane Combustion from Stoves Emits Benzene and Increases Indoor Air Pollution" the data and discussion are about the release of the kinown carcinogen benzine into peoples houses. Your comment is about a completely different study and harm and therefor is off topic on this thread. You often post comments that don't really relate to the OP but complain that scientists are making some sort of mistake. Perhaps if you were on topic you would have less to complain about.
I doubt your complaints about PAF have any merit. Professional scientists are better informed than anonymous internet posters.
It is beyond any doubt that gas stoves release large quantities of harmfull pollution into the homes where they are used. You are arguing about a single tree when the forest is indisputable. The gas industry kinew as early as 1911 that gas stoves released harmful pollution into homes and damaged peoples health. This iinformation has been hidden by the fossil fuel industry to further their profits.
In any case, induction stoves, which release no detectable benzene, are better than gas stoves to cook on. You are arguing against the rising tide. In 30 years gas stoves will be as outdated as coal stoves are today.

David-acct at 21:39 PM on 29 June 2023Gas stoves are even worse for our health than previously known, new study finds
pubmed.ncbi.nlm.nih.gov/24429203/
Curious why the study "Cooking fuels and prevalence of asthma: a global analysis of phase three of the International Study of Asthma and Allergies in Childhood (ISAAC)" was omitted from the meta study showing that 12% of asthma was caused by gas stoves. This study involved 500k + children. Key statement "In both age groups, we detected no evidence of an association between the use of gas as a cooking fuel and either asthma symptoms or asthma diagnosis."
Also curious why population attribution fractio was used when it is widely known to be less than robust when there are multiple cofounding variables. Asthma is a disease that is trigger by numerous factors.
The big complaint is that PAF doesn’t work when there are multiple confounding variables. The challenge for academics unfamiliar with the tool PAF is found in many widely used epidemiology texts, but often with no warning about invalidness when confounding exists.
ajph.aphapublications.org/doi/pdf/10.2105/AJPH.88.1.15
Moderator Response:[BL] You have previously made an argument against using PAF (probability attribution fraction) on this previous post about gas stove health risks.
On that previous thread, many of your errors were pointed out, and you did not engage in discussion - neither making counterarguments, nor admitting your mistakes.
To simple keep making the same arguments, without responding to criticisms or correcting errors, borders on several aspects of the Comments Policy, such as excessive repetition and sloganeering.

Gas stoves offer convenience in cooking, it is important to be aware of their potential health implications. Taking appropriate measures to improve ventilation and considering alternative cooking methods can help minimize the risks associated with gas stove use and promote a healthier living environment.

gws at 00:53 AM on 29 June 2023Gas stoves are even worse for our health than previously known, new study finds
Well, as is covered in the paper, methane flames have long been known to create benzene as a minor combustion product. The EPA even has an estimate of the associated annual national emissions (also in the paper).
The main point thus is not the finding that benzene is emitted from gas stoves, but that those emissions are much larger than the previous emission factor derived from a "clean" combustion suggested they are.

"The explanation for this observation was based on the pioneering work of Eunice Foote (in 1856) and John Tyndall (in 1859), who independently discovered that several gases, including carbon dioxide and water vapour, could trap heat."
This 2019 Research Article in The Royal Society Journal of the History of Science indicates that they independently made their discoveries: "Eunice Foote, John Tyndall and a question of priority"

Robotic Reading: Has the greenhouse effect been falsified?
While Earth’s climate has changed throughout its history, the current warming is happening at a rate not seen in the past 10,000 years.
According to the Intergovernmental Panel on Climate Change (IPCC), "Since systematic scientific assessments began in the 1970s, the influence of human activity on the warming of the climate system has evolved from theory to established fact."1
Scientific information taken from natural sources (such as ice cores, rocks, and tree rings) and from modern equipment (like satellites and instruments) all show the signs of a changing climate.

One Planet Only Forever at 06:24 AM on 25 June 2023Skeptical Science New Research for Week #25 2023
BaerbelW,
The education-related action by Finland is a helpful action in parallel with, but not part of the scope of, the UN actions regarding Information Integrity on Digital Platforms.
A major 'non-censorship' action discussed in the UN document is developing ways to effectively keep disinformation, misinformation and hate messages from being profitable, especially by controlling advertising placement. A related action would be for responsible advertisers to stop advertising on platforms that do not effectively do that.
During my MBA education in the early 1980's my course on Marketing began with the professor telling us that we will be learning about the ability to be temporarily successful by being misleading and warning us about the unsustainability of that Marketing approach.
Attempts to benefit from Disinformation are nothing new. Digital Platforms are just the latest, and potentially most damaging, development that can be abused that way, especially with the rapid unregulated development of AI.
-
One Planet Only Forever at 05:47 AM on 25 June 2023Skeptical Science New Research for Week #25 2023
Nigelj,
I am responding hoping to encourage you to read the UN document about Information Integrity on Digital Platforms.
I agree that Harari’s “21 Lessons for the 21st Century” (and “Sapiens”) are helpful presentations. I read both books a while ago. Your comment prompted me to revisit “21 Lessons ...”
“The Ecological Challenge” sub-section of the “Nationalism (Global Problems Need Global Answers)”, a chapter about the problems caused by nationalism, is aligned with the new UN initiative regarding the harm of successful disinformation production and promotion. Another tragically relevant chapter today is the “Post-Truth (Some Fake News Lasts Forever)” chapter.
The item from Harari’s book that seems most relevant to the new UN initiative is from the “Education (Change Is the Only Constant)” chapter. Though not explicitly stated, the implication is that people who resist increasing their awareness and resist improving their understanding of what is harmful and helpful to the development of sustainable improvements for the future of global humanity ‘will potentially need legal or other government actions to limit the harm done by their preference for preserving a misunderstanding or lack of awareness’.
In the chapter on Education, Harari makes the following important point:
So what should we be teaching? Many pedagogical experts argue that schools should switch to teaching “the four Cs” – critical thinking, communication, collaboration, and creativity. More broadly, they believe, schools should downplay technical skill and emphasize general-purpose life skills. Most important of all will be the ability to deal with change, learn new things, and preserve your mental balance in unfamiliar situations.
The new UN initiative regarding the harm of disinformation, misinformation and hate on digital platforms, including its further development and implementation, is a “four Cs” type of action.
I would encourage you to read the complete UN document. Though I can quickly scan a document, when reading I am usually slower than others because I tend to read every word. It took me 40 minutes to read the entire text (not reading footnotes). For comparison, the Harari sub-section on The Ecological Challenge was a 10 minute read. And it is only 1/4 of the important “Nationalism” chapter. And that entire chapter is only 6% of the book’s ‘well worth reading’ content.
Regarding your stated concern:
However I'm not too keen on governments or the news media or other organizations becoming censors of information. I read George Orwells book 1984 recently and it certainly does a good job of raising awareness of the dire consequences of governmnet and media censorship even if it's well meant.
Of course we do have some established and reasonable limits on free speech, like laws against inciting violence but they are minimal and related to law breaking. I'm talking about going beyond this.
Your concern is addressed in the UN document. Also, the interventions you are accepting are ‘interventions to limit harm done’. That is, or should be, the fundamental principle of laws and their restrictions of freedom. Tragically, I agree that sovereign national or regional governments and pursuers of profit cannot be trusted to constantly govern their law-making, regulation-creation, enforcement or other actions to limit harm done. Pursuits of popularity and profit can create interests for individuals and sub-groups of global humanity that are in conflict with correcting harmful developments and conflict with developing sustainable improvements for global humanity. Those damaging ‘developed and developing conflicts if interest’ include the potential for the sub-group of ‘all of current-day humanity’ having interests that conflict with the development of a sustainable improving future for global humanity.
So, Harari’s book is informative and exposes many important issues. However, the UN document is doing the harder work of applying the ‘four Cs’, to develop global change regarding the integrity of digital information to limit harm done. The section titled “What is the relevant international legal framework?” (page 9) addresses the matter of free speech (as do other parts of the document). It is less than a 3 minute read and opens and ends with:
The promotion of information integrity must be fully grounded in the pertinent international norms and standards, including human rights law and the principles of sovereignty and non-intervention in domestic affairs. In August 2022, I transmitted to the General Assembly a report entitled “Countering disinformation for the promotion and protection of human rights and fundamental freedoms”.15 In the report, I laid out the international human rights law that applies to dis-information, including the Universal Declaration of Human Rights and the International Covenant on Civil and Political Rights. Under these international legal instruments, everyone has the right to freedom of expression.16
...
In its resolution 76/227, adopted in 2021, the General Assembly emphasized that all forms of disinformation can negatively impact the enjoyment of human rights and fundamental freedoms, as well as the attainment of the Sustainable Development Goals. Similarly, in its resolution 49/21, adopted in 2022, the Human Rights Council affirmed that disinformation can negatively affect the enjoyment and realization of all human rights.And the following is a quote from the beginning of the section titled “Towards a United Nations Code of Conduct UN” (page 21):
The United Nations Code of Conduct for Information Integrity on Digital Platforms, which I will put forward, would build upon the following principles:
• Commitment to information integrity
• Respect for human rights
• Support for independent media
• Increased transparency
• User empowerment
• Strengthened research and data access
• Scaled up responses
• Stronger disincentives
• Enhanced trust and safetyI encourage people who are concerned about the harm of disinformation to take the time to read the full UN document.

"However I'm not too keen on governments or the news media or other organisations becoming censors of information."
There are other means organizations can prevent - or at least minimize - the spread of misinformation. Warning messages that content has been contested for example, or a setup that would-be commenters or sharers first have to answer a question related to the article before they can do either.
And then, there's that whole idea of inoculation, that goes along with improving media literacy of large swaths of the population. Imagine how effective it would be, if nobody falls for all the FLICC-techniques any longer and mis- and disinformation than no longer gets shared? Finland seems to be well ahead of many other countries in that regard, based on this article published recently:

OPOF, thanks for the very useful copy and paste quote.
The misinformation is very troubling. The climate denialists are still very active although its swiched to some extent from denialism about the science, to denialism about the impacts of climate change and the solutions.
However I'm not too keen on governments or the news media or other organisations becoming censors of information. I read George Orwells book 1984 recently and it certainly does a good job of raising awareness of the dire consequences of governmnet and media censorship even if it's well meant.
Of course we do have some established and reasonable limits on free speech, like laws against inciting violence but they are minimal and related to law breaking. I'm talking about going beyond this.
But at he same time the way Musk has allowed twitter to revert to an open slather for hate and misinformation is equally as troubling. It all leaves me unsure what the best solution is.
However there is no justification for algorithms that send people a deluge of climate denial. This is just manipulation to increase profits.
I recommend this book to people: 21 lessons for the 21st century by Yuval Harari. Very good chapter on climate change and other environmental issues. IMO this man has a great grasp of reality.

I would add that these young plaintiffs, and many others like them (including older concerned people), need help bringing about the increased awareness and improved understanding of the need for significant corrections and improvements of the developed socioeconomic-political systems.
I recommend reading "Our Common Agenda Policy Brief 8 Information Integrity on Digital Platforms, United Nations" (same link as the second item listed in the ‘Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change’ of the "Skeptical Science New Research for Week #25 2023").

One Planet Only Forever at 03:03 AM on 24 June 2023Skeptical Science New Research for Week #25 2023
As an engineer with an MBA I am interested in new information and feedback that helps me understand how to limit harm done.
The weekly Skeptical Science New Research listing continues to be a helpful resource for increased awareness and improved understanding, especially the category of ‘Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change’.
Politics can be understood to be the system for influencing/governing/controlling/delaying the development of social and economic systems and understanding. There is a parallel to engineering which develops new things and changes (improves and corrects) existing things.
Imagine if the engineering of things was significantly influenced, was allowed to be compromised, by disinformation developed by pursuers of status/success in competition for popularity or profit. Now imagine the more massively damaging results if political leadership was influenced/compromised that way (no need to imagine it – just become more aware of today’s developed reality).
Anyone concerned about the harm done by pursuers of personal benefit from disinformation, and the related harmful spin-offs of unjustified sharing of misinformation and the potential related unjustified fear, anger and hatred (which includes the development of hatred for people who try to increase awareness and improve understanding of climate science and the required corrections of popular and profitable developments), would benefit from reading "Our Common Agenda Policy Brief 8 Information Integrity on Digital Platforms, United Nations" (same link as the second item listed in the ‘Articles/Reports from Agencies and Non-Governmental Organizations Addressing Aspects of Climate Change’).
The document is fairly easy to read. And there are only about 16 pages of text in the 29 page document.
The following excerpt, from the section titled “What harm is being caused by online mis- and disinformation and hate speech?”, captures the nature of the challenge/threat and the importance of effective collective limits on the success of people who pursue benefit from disinformation and the related lack of increased awareness and lack of improved understanding of the harm being done:
Similarly, mis- and disinformation about the climate emergency are delaying urgently needed action to ensure a liveable future for the planet. Climate mis- and disinformation can be understood as false or misleading content that undercuts the scientifically agreed basis for the existence of human-induced climate change, its causes and impacts. Coordinated campaigns are seeking to deny, minimize or distract from the Intergovernmental Panel on Climate Change scientific consensus and derail urgent action to meet the goals of the 2015 Paris Agreement. A small but vocal minority of climate science denialists30 continue to reject the consensus position and command an outsized presence on some digital platforms. For example, in 2022, random simulations by civil society organizations revealed that Facebook’s algorithm was recommending climate denialist content at the expense of climate science.31 On Twitter, uses of the hashtag #climatescam shot up from fewer than 2,700 a month in the first half of 2022 to 80,000 in July and 199,000 in January 2023. The phrase was also featured by the platform among the top results in the search for “climate”.32 In February 2022, the Intergovernmental Panel on Climate Change called out climate disinformation for the first time, stating that a “deliberate undermining of science” was contributing to “misperceptions of the scientific consensus, uncertainty, disregarded risk and urgency, and dissent”.33
Some fossil fuel companies commonly deploy a strategy of “greenwashing”, misleading the public into believing that a company or entity is doing more to protect the environment, and less to harm it, than it is. The companies are not acting alone. Efforts to confuse the public and divert attention away from the responsibility of the fossil fuel industry are enabled and supported by advertising and public relations providers, advertising tech companies, news outlets and digital platforms.34 Advertising and public relations firms that create greenwashing content and third parties that distribute it are collectively earning billions from these efforts to shield the fossil fuel industry from scrutiny and accountability. Public relations firms have run hundreds of campaigns for coal, oil and gas companies.35
Mis- and disinformation are having a profound impact on democracy, weakening trust in democratic institutions and independent media, and dampening participation in political and public affairs. Throughout the electoral cycle, exposure to false and misleading information can rob voters of the chance to make informed choices. The spread of mis- and disinformation can undermine public trust in electoral institutions and the electoral process itself – such as voter registration, polling and results – and potentially result in voter apathy or rejection of credible election results. States and political leaders have proved to be potent sources of disinformation, deliberately and strategically spreading falsehoods to maintain or secure power, or undermine democratic processes in other countries.36
Hopefully this UN effort will help reduce the damaging success of disinformation. And hopefully it will be more effective more rapidly than the “Universal Declaration of Human Rights (1948)”.
The powerful ability to benefit from disinformation and its spin-offs of popularity of misinformation and hate requires a significant correction of the developed political systems and the resulting social and economic developments and corrections.
Climate scientists, likely unwittingly, were a significant factor in exposing the problem and forcing the increased awareness and understanding of the need to correct a lot of what has developed, especially the abuse of disinformation by political game players.

prove we are smart at 13:35 PM on 23 June 2023Inside the unexpectedly wild landmark Montana youth climate trial
Consumer capitalism has distracted us all from our connection to nature, we are literally destroying our own ecosphere. From the country of capitalism on steroids another example of why it seems "We can solve our problems, but it's not clear that we can solve our problems and get rich at the same time, and that is the current requirement for all solutions."
Good luck to our 16 young plaintiffs- afterall, it is their future and those that follow who will experience the tipping points set in motion.

One Planet Only Forever at 09:45 AM on 22 June 2023At a glance - Is Al Gore's An Inconvenient Truth correct?
I am reading Greta Thunberg's compilation of contributions by many experts - "The Climate Book" . Hopefully it will effectively increase awareness, and more effectively than 'An Inconvenient Truth'.
Unlike 'An Inconvenient Truth' being attacked by claims that Al Gore made it up, 'The Climate Book' cannot be claimed to be 'Just Greta's opinion'. It is a comprehensive presentation of the history and current understanding of the diversity of implications of human induced climate change. Each chapter is independently written and compelling. But I am particularly impressed by how holistically the issue is covered in the following chapters:
- 1.5 'The science is as solid as it gets' by Greta Thunberg
- 1.6 'The Discovery of Climate Change' by Michael Oppenheimer
- 1.7 'Why Didn't They Act?' by Naomi Oreskes
Go Greta 'the High School Climate Protest Graduate'.

BaerbelW,
Thank you for exposing a minor improvement to my comment.
I should have stated "Without that significant increased awareness, especially in the Nation with the greatest ability to be helpful or harmful, the situation today ..."
As a Civil/Structural engineer with an MBA (in Canada) my personal interest has always been constantly learning to develop sustainable improvements with actions including:
- limiting the harm done by new developments
- correcting dangerous existing developments (reducing the risk of damaging results)
- stopping the use of dangerous and damaging systems until they are corrected (that action can be applied to structures, but not to the developed systems of human activity impacting a planet - changes of the human developed systems and norms is what is required).
The impacts of pollution from fossil fuel activity (extraction through end-use) had been effective arguments against continued fossil fuel use. And they continue to be arguments against continued fossil fuel use even though some reduction of harm has happened due to government intervention in the Marketplace of thoughts and actions.
An Inconvenient Truth expanded my ability to 'try to correct misunderstandings being presented by people who did not want to reduce their ability to benefit from harmful fossil fuel use'. And Skeptical Science, improved by your engagement, has been even more helpful.

A more important question regarding "An Inconvenient Truth" is: Did it increase awareness and understanding regarding the damage to the future of humanity being caused by human climate change impacts (primarily the use of fossil fuels)?
The undeniable answer is YES.
Without that significant increased awareness in the Nation with the greatest ability to be helpful or harmful the situation today would likely be far worse because of less being done to reduce the harm being done.
The people fighting to benefit more from understandably damaging unsustainable activity are still very influential (being more harmful is more profitable and popular if it can be gotten away with, especially if there is a lack of awareness). But they have been steadily 'winning less' of their endless attempts to get away with being freer to believe and do whatever they please.

That comment is very definitely going to get deleted by the mods, Peppers, because you couldn't follow a very simple instruction to post it in the appropriate thread.
Moderator Response:[BL] The comment you are referring to, plus another that followed, have indeed been deleted as off-topic.
Continued behaviour such as this by Peppers will likely result in his posting privileges being rescinded.
On second thought, no point in waiting. Peppers will no longer be participating here.

Peppers, here is a link to the appropriate thread for the breathing CO2 topic. But before you respond, please take the time to read the article and consider the science presented.

peppers at 05:01 AM on 19 June 2023Cranky Uncle: a game building resilience against climate misinformation
Philippe, your ad hominem aside, I went to your thread shown and it is far from decided. The cycle discussed is not calibrated for a 5 times increase of people breathing. There is a rush to return to fossil fuel as the cause on that thread.
I wouldnt be surprised if fossil fuel were paramount. More people also mean more fossil fuel use. But submission participants who were really interested wanted to know and caculate how much Co2 is emited per person, etc. No one answers that there.
Ill see what I can dig up. Whether it is from breathing or from more fossil fuel use and if it is because we now have more people, this starts a lot of prioritizing junctures over again. I think. Thx D
Moderator Response:[BL] Take this to the correct thread. Any further off-topic posts will be deleted entirely.

Rob Honeycutt at 04:49 AM on 19 June 2023Cranky Uncle: a game building resilience against climate misinformation
I actually take Peppers at his word thinking he actually believes these are pertinent questions to ask. I think he's likely operating at a very low level of understanding on climate science issues, thus everything seems pertinent. The problem is he's not understanding that he's asking very low level questions for which there are simple answers.
It's rather like when climate deniers say the warming is caused by the sun on the ridiculous assumption that climate scientists have never bothered to check.
All very "Cranky Uncle" stuff.
I guess it's far easier to believe there's a conspiracy rather than reading the published research to learn there's not.

Bob Loblaw at 04:05 AM on 19 June 2023Water vapor is the most powerful greenhouse gas
OK, Charlie Brown. I agree that I overstated it when I said that "a lot of IR loss to space comes from the stratosphere". But the important point is that what is seen at any height, looking up or down, is not from a single level above or below the observation height. I think we agree on that.
The IR emitted in the stratosphere will easily be lost to space, due to the small number of molecules at that height, as you mention. We've discussed on other threads how the view of upward-directed IR at high altitude has its origins at different levels, in a kind of inverse view of Beer's Law. Beer's Law tells us the probability that a photon will be transmitted through X path lengths, and the flip side is that it tells us the probability that a photon seen at altitude Z came from a source X path lengths away. A high probability that it came from somewhere close; a low probability that it came from somewhere far away. Exact values of "close" and "far" are dependent on the absorption coefficient for that particular wavelength.
When we "see" an individual photon, we have no idea how far it has travelled, as all photons of that wavelength look the same and carry no memory of the temperature they were emitted at. With a large number of photons, we can start to talk of the probability distribution that it came from altitude Z. It could have been emitted by a layer just below, or well below, or just emitted locally.
In a model, you will have access to internal calculations that tell you how much of the upward flux was transmitted from lower layers, versus how much was emitted within the layer. Field measurements will just give you the sum of the two, though. (In part, it's because field measurements don't have "layers" in the way a model does.)
The MODTRAN page you link to has a button "Show raw model output". That has a lot of detail. I don't know if there is a way to parse that to get the split between "transmitted" "emitted" in the flux. It is a very useful site, none-the-less.
All of which is to say that the words Vidar2032 posted in #383 have serious shortcomings. I don't know if we will see Vidar return with any clarification on his/her thoughts.

Peppers' comment @ 22 above should be on this thread:
This old dead horse has been flogged ad nauseam already and has no value. It casts serious doubt on the sincerity of anyone willing to stoop so low as to use it. It is even worse when it is accompanied by thinly veiled accusations of "suppressing" dissenting voices, accusations for which there is not a shred of credible evidence, especially in the post making the accusation. Anybody who can think quantitatively will quickly see the vacuity of the "human breathing causes CO2 rise" argument. The "just asking questions" trolling method has been seen around here innumerable times, it is no more amusing now than it was years ago.
Moderator Response:[BL] Note that although the displayed text for the "breathing" page is garbled, the actual link behind the text points to the correct page.

Rob Honeycutt at 03:45 AM on 19 June 2023Cranky Uncle: a game building resilience against climate misinformation
Peppers, the problem is when you say something like, "I find some questions intriguing. We must ask more questions."
Asking questions is perfectly reasonable. It's great to ask questions. But you also must put that in context of your level of understanding of the subject. The way you're stating this implies that you're asking something that isn't fully understood by researchers.
You seem to be posing questions for which there are simple answers you're currently unaware of. But you're not taking the time to research if there is a simple answer and rather prefer the idea that you're somehow presenting some new concept researchers haven't considered.
Again, I will state here, in order to ask pertinent questions worthy of substantive discussion you must first spend some considerable time researching the topic before hand.

CO2 is up and still increasing primarily because we continue to rely on fossil fuel sources of energy.
Human respiration is part of the active carbon cycle regardless of the numbers of humans on the planet.
The increase in atomospheric concentration of CO2 is a function of humanity reintroducing sequestered carbon back into the active carbon cycle through buring of FF's.
Human respiration is not an "equalizing factor" because human respiration does nothing to sequester carbon.

peppers at 03:09 AM on 19 June 2023Cranky Uncle: a game building resilience against climate misinformation
Hi Rob, OK thanks for trying to understand. The world has completely changed and Co2 is just a one part of these changes. But this is proving hard to relate, especially in this settled and denier climate.
But Co2 is up, and increasing. Still, there are a lot of questions that have answers that are being suppressed.
Hey, allow me a tickler for you. This is not any main point of mine at all, but I would love to hear a rebuttal.
I understand the premise that human respiration on earth is an equalized basis; that an equal amount of Co2 is expired based on the photosynthesis that happened to create the Co2, as a cycle. What about if one quotient were increased by a factor of 5 times, such as human population inceasing from 1.6B in 1900 to 8B today? Foliage has increased according to Nasa, by not 5 times worth. With 5 times the 'engines' of people respirating Co2 being in play, but without the photosynthesis being up to speed at the same rate, wouldnt the atmosphere be 'banking' Co2 until the other parts of this cycle, used to explain the human equalizing factor, be a possible explaination to increased Co2 in our world? I find some questions intriguing. We must ask more questions.
Moderator Response:[BL] Accusations of dishonesty on the part of scientists snipped.
This is getting increasingly off topic, and increasingly tiresome.
Philippe (below) has pointed you to a proper thread for the breathing/CO2 discussion. Here it is again:
https://skepticalscience.com/breathing-co2-carbon-dioxide.htm
Before you go and pollute that thread, ask yourself:
- How much carbon is stored in 1B people?
- How much carbon is stored in 8B people?
- If people breathing out have been adding net carbon to the atmosphere, how does that jive with your estimates of the change in storage between 1) and 2)?
...and when you sit down to have your next meal (or ten), look at what you are eating, and ask yourself where the carbon in that meal came from, and how long it was in that form between the time it came out of the atmosphere and went into you.
You need to spend some time looking at the cycle of [anything], and thinking over the difference between quantities in storage and quantities moving between different forms of storage. You seem to be extremely confused between high storage and high rate of transfer. You should also look at this post on residence time, and this post on residence time.

a) Has modern medicine reduced infant mortality rates in the past 150 years? Of course.
b) Is that a clear proxy for "human suffering." No. You can have low infant mortality and great human suffering.
c) Is CO2 a necessary byproduct of human advancements? No. Access to energy likely is and thusfar that access to energy has been supplied by fossil fuel sources. But today renewable energy is cheaper and cleaner and will replace those FF sources over the coming decades.
d) Will the human population return to 1B? It likely could and probably should, as that is probably what this planet can reasonably sustain over the future millennia.
There are estimations I've seen suggesting the natural decline in the human population into the 22nd century could be rapid as more of world's people attain first world status. We already see this effect occurring in many first world nations. It's most obvious in Japan due to it's strict immigration laws. The US would have a falling population if not for immigration. China's population is now starting to fall as well.
