Just Dean at 22:04 PM on 22 October 20232023 SkS Weekly Climate Change & Global Warming News Roundup #42
John,
Thanks. This is exactly the kind of exposure/coverage I was hoping to see here.
I have been disappointed with lack of coverage by the media. It is understandable given recent world events and maybe it is early days. Instead of choosing to cover the overall impact of the release on policy, even the Washington Post chose to zero on a single controversial recommendation, the the banning of natural gas lines in areas that haven't been served.
An article by Sarah Isgur writing for Politico last year resonated with me. Here is a quote from that article,
"Climate change can’t be fixed in four-year increments. To effectively stem carbon emissions, the country needs a long-term plan that can be followed for 25, 50, even 100 years — something that can only be put in place by the U.S. Congress."
I think you could argure that this plan would be a good plan to follow and a good plan today beats a perfect plan tomorrow.

Fred Torssander,
In addition to the helpful responses by MA Rogers and nigelj, I offer another perspective regarding the question you ask @3:
How can we know that government action, external governing of the socioeconomic-political marketplace rather than simply allowing marketplace game players the freedom to believe and do whatever they want, has resulted in reduced harm?
This can be particularly challenging if pursuers of benefit from harmful actions deliberately develop and disseminate disinformation and misinformation.
How much less harmful are things today, or will things be in the future, due to policy actions? A more important question not asked by people asking that question is: How much more harmful are things due to a lack of development and implementation of effective harm reduction actions – especially the lack of effective limitations on the ‘freedom to benefit from developing and disseminating disinformation and misinformation’?”
A good example of this problem is NPR’s recent, well researched and presented (and long and detailed), reporting (in parallel with efforts by the regarding the efforts to cast doubt on the science regarding harm done by gas stoves “How gas utilities used tobacco tactics to avoid gas stove regulations”.
Essentially, the understanding is that "...industry-backed reports confused consumers and muddied the science that regulators relied on about the potential dangers of cooking with gas, according to an investigation by NPR and documents uncovered in a new report from the Climate Investigations Center (CIC), a research and watchdog group." And that can happen regarding climate change impact reduction efforts.
The section of the NPR reporting “How Gas Utilities followed the tobacco strategy” presents ways that science can be harmfully biased by the pursuit of money (the American Gas Association – AGA – referred to its pursuit of popular support for gas use in homes as “Operation Attack”). As mentioned in the article “the AGA was hiring researchers who previously accepted research funding from tobacco companies”.
A particularly enlightening part of the NPR article is
“Ralph Mitchell of Battelle Laboratories conducted work for the tobacco industry and had sought funding for research from Philip Morris in 1964 and the Cigar Research Council in 1972. Mitchell and colleagues at Battelle and the Ohio State University reexamined earlier studies that concluded there were health problems linked to use of gas stoves. Using an alternative, and in some cases controversial, analysis technique, Mitchell's team found "no significant difference in reported respiratory illness between the members of households cooking with gas and those cooking with electricity."
None of the authors of the 1974 Battelle paper are alive today to answer questions about their work.
"The research in question occurred nearly 50 years ago, and it would be inappropriate to speculate on the researchers' methods or conclusions," said Benjamin Johnson, spokesman for Ohio State, in an email to NPR. A Battelle spokesman offered a similar statement and wrote that the organization "conducts research that conforms to the strictest standards of integrity."”
It is challenging to ‘conclusively prove the harm reduction of a policy action’. The only ‘certain way to eliminate doubt about the benefits of harm reduction actions’ is to have a parallel planet where the only difference is the action in question with monitoring for a long enough period of time to be highly confident of the ‘measurable differences’. Without that ‘impossible proof’ any suggested harm reduction action is open to the ‘raising of doubt about its merits’. Of course, there is also an inability to be certain about the benefits of actions that are potentially harmful ... but the potential perception of personal benefit can tragically over-power the ability to learn to be less harmful and more helpful.
An obvious problem is the ways that disinformation and misinformation efforts can unjustifiably raise questions about the effectiveness of ‘likely very effective harm reduction actions’, especially when ‘perceived benefits’ have to be given up to reduce the damage being done, or when being less harmful requires more effort or is more expensive.

"It's great - in a way - to have my suspicions and my amateurish comparisions between reported emissions of GHG and measured atmospheric CO2 confirmed by Washington Post no less!"
Yes although I think we all had those suspicions. However IMO while the under measurement of emissions is very concerning, for our purposes it isn't the big issue, because its been reasonably constant going well back. As I stated the big issue is the trend in emissions whether increasing or declining over time, and that trend is likely to be roughly accurate and the growth in emissions looks like it is nearing a plateau from data I've seen.
"Variations in atmospheric CO2, when and if such changes appear, will be hard or even impossible to claim this as an effect of human political (democratic?!) activity. "
Not really. Fistly atmopsheric CO2 levels have been increasing reasonably steadily except that the trend includes a lot of short term wiggles up and down, but those wiggles only last a year or two. They are a result of such things as the yearly seasonal growth cycle, el nino, and the occasional volcanic activity. But these all have very short term effects and known causes.
Once we see something like a change in this atmospheric CO2 trend that lasts at least ten years we could be pretty confident its because of reducing human emissions. It's very difficult to see what else it could be, because no natural cause of emissions is likely to cause a ten year effect on the trend. And if it did it would have to be massive, unprecedented volcanic / geothermal activity of some sort and we would certainly notice that.
"Even in the case that the figures and charts showing temperature confirmed the good news, they would have a margin of error +23%, -0%(!) depending on what the reporting parties (states/nations) pleases."
Temperatures will not be 100% accurately measured, but I doubt temperatures would be that innacurate as 23% out. Where did you get the number?
However I would say atmospheric CO2 levels would be a bit more accurate than temperatures (or emissions trends) and would be the most compelling proof we have made a difference provided we see a decent 5 - 10 year difference in the trend. CO2 levels are quite accurately measured.
"And worse. The emissions of type iii in my first comment, will be compleatly hidden!"
You mentioned el nino and volcanoes. But el nino is not hidden. It is a well known cycle and we know approximately what effect it has on CO2 emissions and its a very short term effect of a couple of years. El nino does not explain long term (greater than five years) trends in CO2 levels.
And volcanic activity is not hidden. Scientists monitor this activity. Unless there is a massive krakatoa sized eruption it is not a significant generator of CO2. Its more significant related to aerosols.
"Lastly: More power produced by "significant solar and wind power" does not neccesarily result in less power produced by burning fossil fuels.Remember Jevons Paradox!"
Jevons paradox says (roughly) that making energy use more efficient does not decrease total energy use, and this has proven to be true, unless you actively fight against the paradox. Germany has had some moderate success making energy use more efficient and also decreasing total energy use, but its required some tight government lead incentives and programmes. And Germany is very disciplined as a people, so other countries might struggle to emulate their modest success.
Regarding the wind and solar power issue, I'm not sure its strictly a Jevons paradox issue because we are not trying to achieve more efficent energy use "per se". We are substituting renewables for fossil fuels. So far those efforts have only stopped the growth in fossil fuels, but as wind and solar power uptake improves in scale, fossil fuel use will fall in absolute terms and has already done in some places. For example, Paraguay, Iceland, Sweden, and Uruguay and France get something like 90% of their electricity from low carbon sources.

It's great - in a way - to have my suspicions and my amateurish comparisions between reported emissions of GHG and measured atmospheric CO2 confirmed by Washington Post no less! But the problem is still there. Variations in atmospheric CO2, when and if such changes appear, will be hard or even impossible to claim this as an effect of human political (democratic?!) activity. So how can we build an informed opinion on claims that "governments have made substantial progress in curbing their climate pollution" and even that "global temperatures are on a less dangerous path than they were a decade ago" which can't be seen, at least I can't see it in the temperature data? Or in the CO2 data.
Even in the case that the figures and charts showing temperature confirmed the good news, they would have a margin of error +23%, -0%(!) depending on what the reporting parties (states/nations) pleases.
And worse. The emissions of type iii in my first comment, will be compleatly hidden!

"The still accelerating growth of the CO2 part of the atmosphere can have several types explainations - I think. i) First of all (Occhams razor) itt might be that the growth is actually accelerating, and the measurements of emissions of GHG are wrong or falsified. There is still very big money being invested in further expanded use of fossil fuels. "
There is good evidence measurements of humanities total yearly CO2 emissions under report emissions by as much as 23% (much of this is agricultural related emissions) as below:
www.washingtonpost.com/climate-environment/interactive/2021/greenhouse-gas-emissions-pledges-data/
But this has probably been a roughly consistent under reporting over time. We are interested in rates of change and trends. I think its likely that emissions growth is starting to level off. Coal use has started to level off, and the world is definitely building significant solar and wind power and this sort of thing can be independently verified.

MA Roger @4;
Thanks for your answer.a) My use of the word fraction was not meant to create misunderstanding. I ought to have used part or ppm instead. Sorry.
1.) The still accelerating growth of the CO2 part of the atmosphere can have several types explainations - I think. i) First of all (Occhams razor) itt might be that the growth is actually accelerating, and the measurements of emissions of GHG are wrong or falsified. There is still very big money being invested in further expanded use of fossil fuels. ii) Then comes non-antropogenic generation, which varies with the activity of volcanoes and the weather, like El Niño that you mention. iii) Then there is the different effects of growing CO2 part of the atmosphere and of rising temperature. Like for example melting ice-lids on gas kettles. Some containing methane.
There seems to be an adequate amount of scientific work on the non-antropogenic and maby also on the iii) category. But how much is done on the question of mistaken or falsified measurements of the emissions?
The temperature anomaly could be verified by scientific use of a common houshold thermometer. At least in populated areas.
Maby that makes temperature the only useful and reliable measure? In that case mabe good news using other measures should comment on the discrepancies between those and the rising of the temperature?[Berkeley Earth story link]

MA Rodger at 18:28 PM on 20 October 2023New report has terrific news for the climate
Fred Torssander @3,
That's not so easy to fathom.
You presumably** ask about atmospheric CO2 levels.
They should theoretically begin to stop increasing at an accelerating rate when we stop pumping CO2 into the air at increasing rates. So far, our emissions are leveling off but not yet levelled off.
And if we could actually begin to drop the rate of emissions (and we need to do this quickly), the rate of increase in atmospheric CO2 levels would begin to slow and helpfully they would level off roughly when we have halved emissions***.
So a long way to go, theoretically.As for when we should see the good news, the increase in annual CO2 levels is impacted by El Niño (which changes many rainfall patterns across the globe and wobbles annual CO2 increases by some +/-0.5ppm). These resulting wobbles seen in the CO2 increase make it difficult to be precise as to the actual state-of-play. So we can see that the decadal increases**** since 1960 have been accelerating strongly (+0.9ppm/y, +1.2ppm/y, +1.6ppm/y, +1.5ppm/y, +1.9ppm/y, +2.4ppm/y) but being more precise is difficult. While the beginning of the present decade 2020-22 does show the lowest 3-year average increase (+2.2ppm/y) since 2012-14 and Covid would have not made a big change to that, the strong La Niña impacting 2020-22 will have made a big difference.
(** The word "fraction" is not so useful here as its usual use is in the 'Airborne Fraction' which is the ratio of [increase-in-atmospheric-burden] to [the-emissions]. It takes 2.16Gt(C) to raise atmspheric CO2 by 1ppm. So our emissions of ~10ppm would have seen atmospheric levels rise by +4.6ppm if Af=100% & all the emissions remained in the atmosphere.)
(*** The 'Airborne Fraction' is running at about 50% but this is not all because of a single year's emissions. Only a few percent would be due to the immediate annual emissions. The 50% is the sum of the decreasing 'few percents' from years running back many decades.)
(**** The 'trend' numbers given by NOAA on their 'trend'page are a bit odd as they compare only the months at the start/end of the years, not the whole 12 months which I use in this comment. The NOAA method actually adds a bit more wobbliness to their numbers.) -

Thank you for the steer, Dean! The NAS report is of exactly the type we like to include.
The "purpose and methods" boilerplate could use some updating. Especially it doesn't mention at all our "government/NGO" section, added a couple of years ago. Marc Kodack handles that part of the weekly compilation and it's entirely manual. With "final assembly" happening on Wednesdays, a Tuesday release date ends up as a bit of a squeaker as to whether an item will get in the same week's review.
As well, it's possible to have a clean miss; a glance at Marc's bio shows how well suited he is for this work, but it's a big world emitting a constant Niagara of material for consideration. It's undoubtedly the case that more eyes would help, if they can be harnessed properly. We have the UI parts in place to widen our net by soliciting community input but that will need process methods and additional labor to support without descending into chaos. Fingers crossed, we may arrive there.
In the meantime, we're delighted to accept suggestions here and in the case of the NAS report we'll make sure it's in next week's edition even if it doesn't surface directly for Marc.

According to this article, the most common lithium ion batteries now will be replaced by lithium iron phosphate batteries (LFP) in the near future. Major car manufacturers are making the switch already. So, no cobalt, manganese or nickel, making them cheaper, while having less environmenal impact, and almost impossible to catch fire.

I'm reluctant to engage with a commenter that peppers a comment thread at a rate of one every couple of hours for almost two full days without establishing some form of understanding as to their purpose. But here goes...
Rabelt @46,
The OP does not claim to show that "emission from FF are responsible" for changing levels of atmospheric CO2. It is providing an explanation of "how measurements of changing isotopic ratios are described" and this in regard to the atmospheric 13C:12C ratio.
This ratio is shown in the OP fig3 waggling over a whole millennium in a very similar way to the level of atmospheric CO2. CO2 levels go up/down and the 13C:12C ratio goes down/up. Such a remarkable correlation tells us (although this is beyond the message of the OP) that the source (and sink) responsible for the changing CO2 levels has a 13C:12C ratio far lower than the atmosphere. Thus that the oceans cannot be the source/sink of that extra carbon waggling the atmospheric CO2 levels.
The source of this rogue CO2 messing up the atmosphere is thus plants, either by their direct destruction or indirectly via fossil fuels which retain the low 13C:12C ratio.
(The middle section of your comment @46 mentions "this change" but does not make entirely plain whether you refer to the "changes in discourse" or the "changes in Delta C13". So, if it is in any way relevant, it is not clear which you don't accept.)
Your comment make two final assertions which I find a little odd. You suggest annual and cumulative CO2 emissions 1750-1900 do not explain the changing atmospheric CO2 levels, the latter being "too small". Further you suggest a mismatch in the AtmosCO2:Delta C13 ratio "the 1950s-2010s periods."
The Global Carbon Project is always a good go-to source for annual carbon emissions. Although their historic LUC data only runs back to 1850, it is plain from their various source-sink numbers that the Atmospheric Fraction does not show emissions that are "too small" prior to 1850. You may have sight of other numbers which show it different and if so you do need to explain such 'other numbers' properly. (I note @34 you put the CO2 emissions for 1850 = 0.2Gt(CO2). This is presumably ignoring the LUC emissions which would increase the full 1850 emissions to 2.6Gt(CO2) using the Global Carbon Project numbers.)
It is also not clear what you are considering with this 1950s-2010s mismatch which you perceive between accelerating CO2 levels and steadily decreasing Delta C13 levels. If it is the OP's Fig 3 (& I don't see a problem there), perhaps a sight of the original may help as it shows the data points without the assumed solid δ13C trace.

Rabelt at 16:48 PM on 18 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Rob Honeycutt,
This post claims emission from FF are responsible yet decides to use a completely different measurement, that changes the discourse from emissions to co2 concentrations, which as the other kid mentioned can not be the cause of changes in Delta C13; even accepting this change, which I dont, the problem still persist, 1750-1900 yearly and cumulative emissions are unable to explain the changes in co2 concentrations, they are too small, and the co2 concentrations show an acceleration during the 1950s-2010s periods that dont match with the steady decrease in Delta C13.
Moderator Response:[BL] This simply repeats previous assertions without evidence. This violates the portion of the Comments Policy that states:
Comments should avoid excessive repetition. Discussions which circle back on themselves and involve endless repetition of points already discussed do not help clarify relevant points. They are merely tiresome to participants and a barrier to readers. If moderators believe you are being excessively repetitive, they will advise you as such, and any further repetition will be treated as being off topic.

Moderator Response:[BL} Alas, you have forced me to disconnect from the discussion, and switch to moderator role.
You raised the issue of the IPCC and "the main narrative" in comment 22, and clearly it was nothing more than bluster.. You obviously have nothing constructive to say. Please read the Comments Policy. This post is a clear violation of t he following portion of that policy:

Rabelt... Assuming your "main narrative" is "[d]elta C13 starts decreasing around 1750 and continues to decrease ever since, the main narrative blames it on FF"... Your narrative is a basic misinterpretation of the science.
The C13 narrative (if you want to call it that) is merely the physics behind carbon isotopes for natural sources vs through burning hydrocarbons. That it. If you're saying this area of physics is wrong, you need to explain why.
The accepted understanding of this physics merely creates a prediction that can be tested. If the increasing concentrations of CO2 are primarily due to the buring of FF's, then we should see a corresponding relationship with C13. And that's all this is. It's just one piece of evidence that contributes to the scientific understanding that our uses of FF's is the source of increasing CO2 in the atmosphere.

This report is yet another example of climate alarmism and is nothing more than choosing to ignore the facts to fabricate yet another over blown story. The facts are that the algal blooms have affected all coastal U.S. states. They are most commonly caused by dinoflagellates or diatoms but can also be caused by cyanobacteria. Harmful blooms form where there are high levels of nutrients such as nitrogen and phosphmates, otherwise known as fertilisers used by farmers which run off the land into rivers, lakes and seas. The blooms are not just at surface level but also much deeper and will be harmful to ecosystems in the sea, hence the lack of krill for the whales, nothing to do with climate at all. It is yet another man made problem but not one that can be attributed to climate change.
Dont climate alarmists get that the more they make up stories where they ignore the real facts that more and more people are turning away from climate change and see it as a hoax. This is doing a great disservice as I want to see much more care being taken of our planet but these idiotic stories are back firing.

Rabelt @ 40., 41.
All I see is your narrative. It does not resemble any scientific narrative. In comment 22, when you introduced "main narrative", you said:
...so I will continue using the main narrative (IPCC, NASA, CSIRO, etc) as the argument I am debating
Since you want to use the IPCC as a source, please show the sections of the IPCC reports that illustrate this "main narrative".

Bob Loblaw,
Now show me where does the IPCC address those changes in the trends, or where in this great library of knowledge there is an explanation fo them.

Bob Loblaw,
Already said what the main narrative had to say about C13, comment 34.
If you want the entire narrative, you have the reports of the IPCC.

There has been not a single argument coming from you except the massively broad term "Carbon Cycle" and mentioning that you read followed as caused and supposedly it was my fault

Once again, you have nothing more than your eycrometer of patterns. You continue to ignore any sort of analysis that actually looks at the physics of the carbon cycle.

Rabelt:
Where is your explanation of exactly what "the main narrative" is?
Until you actually provide a coherent argument, there is no counter-argument to present.

Rabelt at 06:07 AM on 18 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Bob Loblaw,
Let me explain your own field of expertise: Delta C13 starts decreasing around 1750 and continues to decrease ever since, the main narrative blames it on FF.
I see that the human emissions are too low for the mayority of this 270 years period, as we can see in the cumulative and yearly emissions.
I also see that even though the emissions multiply by tens and hundreds of times the speed of Delta C13 decreasing doesnt show any meaningful acceleration.
You use the wildcard "Carbon Cycle", as if that explains something; supposedly this wildcard is able to produce massive amount of co2 with a "deficit" in C13 to compensate the 1750-1850 yearly emissions, as the emission from this years are 0.048 GT of CO2 per year on average with a max of 0.2 GT in 1850, while also making the decline of Delta C13 steady from 1750-1950, even though the yearly emissions have multiplied from 0.01 GT of CO2 per year to 6 GT of CO2 per year.
This also happens during the 1960-2015 period in which the decrease of Delta C13 is quite steady even while the yearly emissions change from 9 GT of CO2 per year to 35 GT of CO2 per year.

Bob Loblaw,
So you dont have an argument so you evade the topic, great.
Again no argument so you avoid responding to you putting words in my mouth and not responding to the strawmaning mentioning the "Carbon cycle" as if it was so kind of deity, I am sure you are of much help in the debate. If you are gonna accuse me of not understanding the effects of the Carbon Cycle in Delta C13 I would like to see a quote or a set of specific pages, not a extremely vague statement that mentions the entirety of the concept "Carbon Cycle".
So follow to you means caused, got it, it is my fault for expecting a minimum of comprehension; still I already said that there had to be a natural process that changed co2 concentrations and Delta C13, not sure why you continue to not read it.
Didnt adress any point just wanted to score another "debate bro" point using that joke called FLICC, debate the argument not your ego, please, and thank you. We even have a name for people like you, imagine how unoriginal your tactics of debate are.
"I am talking about emissions not co2 concentrations" It is not directed at you, but following (not causing) another line of debate with another person, but using your own fantasies now I am gonna start accusing the author of this post of believing that co2 concentrations causes changes in Delta C13, because mister Bob teached me how I am supposed to read others people words.

Bob Loblaw at 04:33 AM on 18 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Rabelt @ 28: "quote which part I said anything dismissive about the carbon cycle."
The fact that you say virtually nothing coherent at all about it - when it is essential to understanding the graph/data you criticize - is all the evidence that is needed.
@ 29: "I love how the guy putting words in my mouth is acussing me of strawmaning his arguments,"
I am not accusing you of strawmanning my arguments - you have strawmanned "the main narrative" (in the context of what climate science - e.g., the IPCC - has said). If you want to provide a counter-argument, you need to give a thorough explanation of "the main narrative" (including the carbon cycle). Until you provide actual evidence that you have at least a basic level of understanding the carbon cycle (not just an assertion), then you're just blowing smoke.
Also @ 29: "Quote my comments and explain why they follow your supposed "logical consequences"
I did quote you, in my comment 19.
You finish with "I said Delta changes previous to human emissions following co2 concentration not FF emissions as there were none, and the ones that existed were accountable for insignificant amounts of co2." The way you have worded this suggests that you think that either CO2 concentration changes cause C13 changes ("delta changes ... following CO2 concentration"), or that C13 changes cause CO2 concentration changes ("delta ... accountable for ... CO2").
You have not responded directly to that, to provide any sort of clarification or indicate what you really meant. Yet you come back with "Again, never said co2 concentrations cause changes in Delta C13..." From this view, it looks as if you are just dodging the question.
And now you are stating "Differences in the carbon cycle are expected, yet only are accepted if they dont contradict the main narrative,"
Congratulations. You have now scored a third point on FLICC - the 5 techniques of science denial. - Conspiracy theories.
Since you clearly are unable to actual specify what "the main narrative" is, your speculation about what contradicts it is not worth the electrons used to transmit it.
And finally, @ 30 "I am talking about emissions not co2 concentrations"
Yet the graph that you began this whole flood of nonsense over is a graph that shows two things as a function of time: CO2 concentrations, and C13 isotope ratios. There is no coherence or consistency to what you say. Buy a clue please: CO2 concentrations, CO2 emissions, CO2 uptake - all are part of the carbon cycle that you keep dismissing. Oh,, sorry - not "dismissing" but just "ignoring".

Thank you for this example of cooperation and collective effort. More spotlights should be directed to these types of examples showing the power of working together: it's really what makes the world go around.
Too bad so much money making is based on riling people up into opposing camps! We've kinda blown the positive potential of the internet by building our algorithms on the fact that fight or flight is a more reliable attention getting device than examples of community building and cooperation.

I am talking about emissions not co2 concentrations.

Rabelt... "...yet the annual and cumulative emissions are too small to create any perceptible change..."
By what method are you making this determination? When I look at the graph I see a clear and proportional correlation between the two.

Rabelt at 23:57 PM on 17 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Bob Loblaw,
I love how the guy putting words in my mouth is acussing me of strawmaning his arguments, 10/10.
Quote my comments and explain why they follow your supposed "logical consequences", just saying it again, as you dont show the ability to read the comments I am posting.
"You see a correlation over the period 1750-1860, and then expect to see the exact same response at later times" During this entire period is a stable trend downwards, yet emissions during this period are incapable of generating such a trend. This is only one of the multiple periods I talked.
Again, never said co2 concentrations cause changes in Delta C13, I even said that there had to be other natural mechanism capable of producing this effect. What a great ability to read.
Differences in the carbon cycle are expected, yet only are accepted if they dont contradict the main narrative, unless you wanna say that the decrease during the beginning of the industrial revolution was natural, which I completely agree.
Again another fantasy about what I belive or think, saying I am trying to invalidate climate science, I only talked about 1 specific thing but the entire field will crumble to the ground for just this specific inconsistency, what a joke of an argument.
Sorry to say that your ability to read degrades quite quickly, I never said you didnt have knowledge on the carbon cycle, I said you didnt have any authority to say what the main narrative states, and I was right, as you are just another of the thousands of people that provide research and not a spokesman or director of the main organizations.

Rabelt at 23:25 PM on 17 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Michael Sweet,
Again for the 50th time, I have never said that the carbon cycle is irrelevant, inexistent or not worth being mentioned, on the contrary, yet for some reason 3 of you have repeated the same dumb statements like it addresses anything I said; quote which part I said anything dismissive about the carbon cycle.
I worry about your ability to see, if you are saying the 1000-1800 period is flat, there is multiple trends that vary from increase to decrease, those trends fit Delta C13 with co2 concentrations, not emissions; for industrial periods (1750-2015) we can see 3 main trends, 1750-1900, 1900-1960 and 1960-2015, this 3 trends periods encompass multiple different trends in co2 emissions

Bob Loblaw at 23:20 PM on 17 October 2023From the eMail Bag: Carbon Isotopes, Part 2: The Delta Notation
Rabelt:
Again, you are saying "I never said..", and avoiding the logical consequences of what you are saying.
The conversation has all the hallmarks of the following sequence:
A person says:
- A = 3
- B = 8
- C = A+B
Someone else says "So, you are claiming that C = 11?
And the first person says "I never said that C = 11. Stop putting words in my mouth."
You keep referring to "the main narrative". Unfortunately, what you have written here tells me that your idea of "the main narrative" is pretty much a strawman. I don't think you have any clue how the carbon cycle works, how different carbon isotopes fit into that cycle and why they would change over time.
Your comment at 23 illustrates this very well. You see a correlation over the period 1750-1860, and then expect to see the exact same response at later times. You seem incapable of realizing the following:
- There is no direct cause-effect between C13 ratios and atmospheric CO2 levels. They are part of the same large carbon cycle, but one does not cause the other, regardless of any fantasies you have about "the main narrative". As long as you ignore all the indirect connections (known as "the carbon cycle"), you will continue get everything wrong.
- The different time periods have different conditions, different fluxes, and different relative important of atmospheric inputs and sinks of carbon as a result, they would be expected to show slight differences in the patterns.
- Your overly-simplsitic "I see with my little eye..." analysis is telling us nothing about the global carbon cycle. Where you see inconsistencies you think can't be explained (because you won't look) and invalidate climate science, climate science sees the carbon cycle working as expected (because they have looked).
You are hitting two of the five main components of FLICC - the 5 technicques of science denial:
- Logical fallacies [your misunderstanding of "the main narrative" is just one]
- Impossible expectations [your overly-simplistic view of what you think should be happening, and your belief that this disproves something]
FYI, yes I have some authority with respect to carbon cycles, having been involved in analysis of forest carbon cycles and storage, and having my name on several publications related to that. You can read more about my background on the SkS Team page.
