Regarding C14, the gradual decline may be due to the nuclear tests that created C14 that is decaying or disappearing naturally. Ref this paper. Also this paper also looks at 13C/12C ratio, saying the following. Is there discussion on this somewhere?

Abstract
Recent studies have provided evidence, based on analyses of instrumental measurements of the last seven decades, for a unidirectional, potentially causal link between temperature as the cause and carbon dioxide concentration ([CO2]) as the effect. In the most recent study, this finding was supported by analysing the carbon cycle and showing that the natural [CO2] changes due to temperature rise are far larger (by a factor > 3) than human emissions, while the latter are no larger than 4% of the total. Here, we provide additional support for these findings by examining the signatures of the stable carbon isotopes, 12 and 13. Examining isotopic data in four important observation sites, we show that the standard metric δ13C is consistent with an input isotopic signature that is stable over the entire period of observations (>40 years), i.e., not affected by increases in human CO2 emissions. In addition, proxy data covering the period after 1500 AD also show stable behaviour. These findings confirm the major role of the biosphere in the carbon cycle and a non-discernible signature of humans. -
pattimer at 22:27 PM on 2 September 20242024 SkS Weekly Climate Change & Global Warming News Roundup #35
It's undoubtedly true that we need to both face denial and how to create solutions ( both at government/ national level and at the individual level). Sceptical science does a superb job at rebutting denial. I also think denial is part of the continual procrastination process and many of those such as the GWFP that have played a huge role in denial of climate change have changed their procrastination strategies. It seems that they will make political gain by accepting long term strategies for climate action giving us "world leading targets"which they will then make further political gain by reneging on them when the time comes to implement them. Another strategy is raising false hopes that are completely unrealistic to delay implementing existing strategies such as implying that our boilers and cars in the future will have hydrogen delivered along pipes. This they know will make people delay personal changes that would otherwise reduce their fossil fuel consumption. So we not only need to face denial of the climate science but also the denial of solutions that could be presently implemented. I personally arrange regularly visits to my home by small groups of individuals to address the myths about heat pumps for example that the procrastinators have been successful in flooding social media with in the same way they spread climate denial.

Eclectic at 21:13 PM on 30 August 2024Climate Adam: Can Coral Reefs survive Climate Change?
Er .... the GBR [Great Barrier Reef] has never been better than now?
Rose-tinted glasses & cherry-picking are probably not the responsible and sensible approach to assessing and managing the GBR.
Heat (and pollution?) will certainly increase over coming decades, for reasons which you already know. So the GBR corals are facing a long uphill battle.
Perhaps the evolution of greater heat-resistance in many coral types (and their symbiotic algae) will occur ~ but will it be fast enough to preserve the majority of the GBR in a diverse form, or will the GBR deteriorate into something approaching a sad "monoculture"?
Maybe that sort of "recovery" of the GBR will occur in the matter of a decade ~ or perhaps there may be a large "valley of death" until evolution catches up. A lot is uncertain . . . but the corals are definitely facing a long uphill battle against the increasing heat.
MadMackz, your views may have been influenced by your innate cheerful & optimistic nature ~ reinforced by the outlier views of Dr Peter Ridd-Micawber and the false smiles of the GBR tourist boat operators.

MadMackz at 11:08 AM on 30 August 2024Climate Adam: Can Coral Reefs survive Climate Change?
The only issue I have with this is that it doesnt really promote the things that people really should also know about coral reef namely the Great Barrier Reef. It is strange how although through the mass events that have killed off so much precious reef, that since 2022 we have observed Record Highs regarding size, growth and overall health of the GBR in all recordable history in its entirety. 3 years in a row! Which is great! Something else that many people dont know is that although record levels of the reef have been observed there has been a detrimental outbreak of starfish which are one of the largest offending predators of the reef, them along with Fish, marine worms, barnacles, crabs, snails and those pesky sea stars all prey on the soft inner tissues of coral polyps. But that still is not the largest Killer of these beautiful reefs. That...would be waves, from cyclones and storms.. Breaking off large pieces of coral at a time and literally shredding it as the waves flatten it to litteral sand. Its a good thing that those cyclones have been showing a decline in frequency and intensity for the last half a decade. One plus of the warm waters though is the spawn of new reef is increased, Once a year, on cues from the lunar cycle and the water temperature, entire colonies of coral reefs simultaneously release their tiny eggs and sperm, called gametes, into the ocean. The phenomenon brings to mind an underwater blizzard with billions of colorful flakes cascading in white, yellow, red, and orange.
In ways that scientists still do not fully understand, mature corals release their gametes all at the same time. This increases their chance at diversity and has shown the mixing of genes to increase their tolerance to the changing climate and temperatures. And finally while individual coral colonies suffer from a degree of bleaching in any given summer. This is a natural process and not of particular concern, what we do know is the reef has never been better than now and heres to another 3 years of Great Barrier Growth.

I want to note that there are sources out there claiming widespread bleaching events are killing off the reef .

Alice’s Hatter spoke in the bizarre tangles called word salad as a result of what’s still called Mad Hatter syndrome. It takes even less than that 1ppm in the chronic doses hat makers breathed in from the mercury nitrate (Hg(NO₃)₂xH₂O) they used for about a century to toughen fur fibers, allowing them to matt together better for a firmer hat. The process was called carroting because Hg(NO₃)₂xH₂O is orange.Phyllobates terribilis, Golden Dart Poison Frog, ‘Orange’ (Imagine a picture here)
Dart poison frogs' batrachotoxin's LD50 is 1/1000th of that (1mcg/kg or 1 part per billion), so if those 2 grains of salt in your hand were batrachotoxin, it's a coin flip whether it would be enough to kill you just by holding it, if you had even a tiny cut on your palm. Sorry, there’s no antidote, and you have about 9 minutes left. It would take 6 salt grains worth of VX, while Botulinum toxin kills at 1 thousandth that amount—1 nanogram, or 1 billionth of a gram/kg body weight. One part per trillion of it can kill.
9 ppm is the maximum indoor safe carbon monoxide level over 8 hours. 200 ppm or greater will cause physical symptoms and is fatal in hours. 800 ppm of CO or greater in the air is fatal within minutes.

Christian Moe at 21:33 PM on 26 August 2024It's cosmic rays
PS to comment 123: Apart from the ion/muon confusion, I'd suggest that human radiation doses are a digression that is apt to confuse the reader as to what the issue is here, especially in a short at-a-glance section.
-
Christian Moe at 20:59 PM on 26 August 2024It's cosmic rays
The current "at a glance" section, second paragraph, appears to confuse ions with pions and muons:
"When cosmic rays hit the top of our atmosphere [...] they interact with the atoms up there producing showers of charged particles known as ions. The ions then head on down towards the surface, where they make up just over ten percent of our typical yearly radiation dose. That's approximately equivalent to three chest x-rays."
In my understanding, cosmic rays hitting atoms at the top of the atmosphere produce pions, charged pions decay into muons, which continue down the atmosphere, creating ions as they pass. Ions are charged atoms or molecules. Ions do not (as such) contribute to your radiation dose. Ionizing radiation does (like muons and the rest of the cosmic-ray cascade products).

Nigelj @2 and Michael Sweet@3,
Thank you for researching and sharing the evidence that clearly contradicts TWFA’s poorly justified opinion that “in our lifetimes ... nobody will have abandoned ... their beachfront homes or estates due to climate”.
Based on a short time doing unbiased investigation and thoughtful consideration I offer the following additional evidence contradicting or weakening TWFA’s poorly justified opinions expressed @1:
- many island nations, like the Maldives, are already suffering destruction and forced escape/migration due to climate change impact induced sea level rise.
- The feet of the Statue of Liberty are more than 150 feet above current sea level ... so ... weird statement.
- The Battery Park City Authority is planning major costly mitigation actions (BPC NEW LOOK: STORM SURGE BLUES link here) to try to ensure that “Battery Park will still be there”. Those mitigation/adaptation actions are a costly distraction that would not have been needed if climate change impacts had been reduced sooner with a lower level of peak total impact like 1.0 C achieved. If those mitigation were not required then all that money/effort could have been expended to genuinely improve the future of Battery Park.
- The Obama homes at the Vineyard and Hawaii both appear to be situated high enough to not be at risk of storm surge damage “during our lifetimes” even if ‘our lifetime’ is the 100 year lifetime of a new born today, as long as global warming impacts are limited to 2.0 C. Of course, if ‘our’ is regarding humanity’s lifetime of potentially many millions of years then those homes are likely not high enough.
A final note: Warren Buffet’s actual statement and the context of it are well presented by Investopedia here. Not quite what TWFA opined.

I visited the outer banks in North Carolina 18 months ago. We stayed in a house on third Street. It was one and a half blocks to the beach. First Street and half of second street were gone.
This week this video was widely on mainstream news of another house there falling in the ocean. I saw a community on the Chesapeake Bay where the houses were uninsurable and a fishing island there is trying to get the feds to spend millions to prevent their island from washing away (a hopeless task).
I saw a video on YouTube of farmers in Vietnam who used to raise rice and now grow salt water fish and crabs. Another foot of sea level rise will overtop their levies and they will become refugees.
The lowest houses are beginning to be washed away world-wide. Insurance rates in Florida and other USA beach front are artificially held down by the government.

nigelj at 07:02 AM on 23 August 2024What should you do to prepare for the climate change storm?
Climate change could indeed make properties uninsurable and hard to sell. From stuff.co.nz:
"Homes on parts of New Zealand’s coast will begin losing access to affordable insurance within 15 years, according to a stark new report. Wellington will be hit first, and Christchurch hardest, but all four major cities will be affected, according to new research led by climate and insurance specialist Belinda Storey for the Deep South National Science Challenge.By 2050, at least 10,000 homes in our biggest cities will be effectively uninsurable, however spiking premiums and policy exclusions could start being felt as soon as a decade from now, it concluded."
"In Wellington, just 12cm of sea level rise could see average premiums more than quadruple for about 1700 homes, the report estimates – if insurers fully priced the increased risk into policies. At those levels, people may effectively find they have no insurance cover, said Storey."
Ten to fifteen years is not far away. So it may pay to research the risks in your area now, and sell well before you suddenly find insurance is unavailable. I would say that when insurance companies start increasing premiums to high levels, or refusing cover at any price it could also happen suddenly without much warning. Decision making ruminates away for a long period then reaches sudden tipping points like other things in life..

Head for the hills! Warren Buffet said the time to be scared is when people are greedy, and the time to be greedy is when people are scared, so it sounds like oceanfront property should become a bargain once the scared migrate to Michigan. My own prediction is that in our lifetimes the Statue Of Liberty will not have wet feet, Battery Park will still be there and nobody will have abandoned Manhattan or their beachfront homes or estates due to climate, it will just be wealthier folks living there, like the Obamas with their oceanfront estates in the Vineyard and Hawaii, with an additional two climate escape pods in D.C and Chicago.

Bob Loblaw at 00:57 AM on 21 August 2024Are climate models overestimating warming?
ubrew12:
As MA Rodger says, climate models do include soil moisture and surface albedo. The surface component of these models will also include vegetation cover, as this strongly influences the evapotranspiration rates. This is an essential part of the climate modelling process, as the surface energy balance has major implications in partitioning energy within the climate system.
The surface energy balance involves:
- solar radiation reaching the surface,
- IR radiation emitted from the atmosphere to the surface,
- IR radiation emitted from the surface to the atmosphere,
- energy transported as "sensible" heat (temperature) between the surface and the atmosphere (on average, upward)
- energy transported as "latent" heat (evapotranspiration, condensation) between the surface and the atmosphere (on average, upward, representing water movement from the surface to the atmosphere)
- energy transported via the conduction of heat between the surface and the subsurface (soil or water).
The concept of a "surface energy balance" is based on the idea that the surface is an infinitely thin plane that separates the atmosphere and the earth (land/sea). With no thickness, it has no mass, so it cannot store energy. There must be an energy balance that sums to zero for all energy flows to or from the surface. In this concept, the land itself is the sub-surface (which can store energy).
NCAR has a good web page describing their models. The overall climate model is built from several components: atmosphere, land, ice, etc. For the land component, the docuimentation table of contents lists (under "special cases") things like "Running the prognostic crop model" and "Running with irrigation".
So yes, it is possible to run these models with various aspects of surface conditions. Whether anyone has is another question - and getting appropriate historical surface data to do so accurately is an even bigger question.
-
MA Rodger at 02:08 AM on 20 August 2024Are climate models overestimating warming?
ubrew12 @3,
The models do certainly calculate soil moisture and account for surface albedo. I don't know how accurately this is done. Presumably, if it were done badly enough to affect the modelling generally, such a failing would be quickly corrected.
You ask this because you wonder whether the 'Dust Bowl' could be the reason for these Corn Belt states having seen such low warming rates 1973-2022. Perhaps they began the period with warming already in place.
The GISTEMP web site easily allows such ideas to be tested. Over the full 1880-2022 period of data, the same low warming trend is still seen across the eastern USA thro' summer months on a global map. It is actually there all year and strongest in Autumn,weakest in Winter & Spring. So using this region to be representative of AGW, it is simply a dishonest cherry-pick (which is what 'Derwood Turnip' is doing). And as a region testing the climate models, as shown in the global map above in the OP, it is again a dishonest cherry-pick (which is what Roy Spencer is doing), although Montana/North Dakota would give a more dramatic result, indeed the most dramatic result.

ubrew12 at 21:58 PM on 19 August 2024Are climate models overestimating warming?
This article includes a graph of the worlds 1970-2023 prediction anomaly. This is pure speculation, but the anomaly in question may not be simply 'unforced variability'. We know that in the 30 years before 1970, the Corn Belt was recovering from the 'Dust Bowl': non-evaporative fallow land was being replaced by irrigated crops. Post 1970 this trend would have continued, as better agricultural practices filled the summer Corn Belt with evapotranspirating crops: a form of human agency the climate models may not include as a boundary condition. If so, then such a overprediction anomaly may also be found in other cropland areas, like in Ukraine.
An opposite effect might be expected in places where evapotranspirating jungle was, post 1970, being cut down and replaced with relatively inefficient ranchlands, soybeans, and palm oil plantations: Brazil and Borneo. Hence, they show up colored blue in that graph.
I'm just speculating. Do the climate models account for this kind of human agency, land-use change, as a boundary condition?
-
MA Rodger at 20:40 PM on 19 August 2024Are climate models overestimating warming?
ubrew12 @1,
Your friend should rest assured that his crystal ball, ouija board and morning cuppa are all safe. Even Foghorn Leghorn can sleep easy in his bed. The fake human 'Derwood Turnip' obtains the best divinations ever in history and he uses other means.
In the case of the corn state summer tmperatures, there is a bit of a disconnect between 'Derwood Turnip' and the information he presents. The actual author is the blunderful denialist Roy Spencer who posted an analysis on his blog in June 2023 and then included it in a pack of nonsense he had published in January 2024 by a bunch called The Heritage Foundation. It took 'Derwood Turnip' eight months to re-post the published graphic.
Such delay is something 'Derwood Turnip' has a history of creating. An example of a shorter 82-hour delay 'Derwood Turnip' created back in 2019 involved Hurricane Dorian, initially a Cat-5 hurricane but soon to be dropping to Cat-2. 'Derwood Turnip' used his position as POTUS and his very own exceptional analytical skills to give warning to the good citizens of Alabama (and others) that they "will most likely be hit (much) harder than anticipated" by Hurricane Dorian which was "looking like one of the largest hurricanes ever."
Yet during this 82-hour delay, the situation with Hurricane Dorian had changed dramatically. Advisory #021 had been updated multiple times (as is normal, with updates 4-times-a-day), having been superceded by Advisory #032A three hours prior to the warning of 'Derwood Turnip'.
The enormity of the wisdom of 'Derwood Turnip' can be seen in his detailed explanation for the remarkable variance between his wondrous analysis and the reality he so often wrestles with.
Trump, Sept. 4: I know that Alabama was in the original forecast. They thought it was get it — as a piece of it. It was supposed to go — actually, we have a better map than that, which is going to be presented, where we had many lines going directly — many models — each line being a model. And they were going directly through. And, in all cases, Alabama was hit — if not lightly, in some cases pretty hard. Georgia, Alabama — it was a different route. They actually gave that a 95 percent chance probability.
It turned out that that was not what happened; it made the right turn up the coast. But Alabama was hit very hard, and was going to be hit very hard, along with Georgia. But under the current, they won’t be.
-
ubrew12 at 15:52 PM on 19 August 2024Are climate models overestimating warming?
Derwood may be put into a position to make climate policy. If not computer models, what predictive tool was he planning to use to evaluate that policy before implementing it? Crystal Ball? Ouija Board? Tea leaves? Chicken bones? Asking for a friend.

One Planet Only Forever at 01:54 AM on 10 August 2024What Project 2025 would do to climate policy in the US
Thank you for sharing this item. It’s a great supplement to the Story of the Week in “2024 SkS Weekly Climate Change & Global Warming News Roundup #29”
Doug Bostrom’s observation about the selective secrecy of the politically conservative collective pursuing Project 2025 is a justified concern.
Harmful exploitation of flaws and weaknesses in the US Constitution is possible and can be very damaging. The US Constitution has been proven to be open to biased poor judgment interpretations. An example is that the Constitution can be interpreted to never require the Senate to vote to approve Supreme Court (SC) nominees. The death of SC Justice Scalia on February 13, nearly 9 months before an election, did not require the New Right Republican Senate to vote on the President’s nominee replacement. But the death of SC Justice Ginsburg on September 18, less than 2 months before an election, resulted in the New Right Republican Senate expediting voting to appoint a new SC justice.Exploitation of that systemic flaw shows how the freedoms and fairness of democracy can only survive if rational judgments govern and the institutions that make a socioeconomic system work as a democracy are defended against irrational influence.
The secrecy regarding the “fourth pillar” of Project 2025 is a serious concern given the following ‘open declaration’ in the item linked to by Doug:
“The 2025 Presidential Transition Project has convened the conservative movement in support of the ideas that will reclaim our nation.”
The New Right Republicans behind Project 2025, including Trump in spite of his denial, do not consider the USA to be a nation for anyone other than ‘their type of people’. By saying “reclaim” they imply that the majority of the current US population is a threat to ‘Their New Right Nation’.
As noted by nigelj @2, Project 2025 is understandably a collective of poorly justified passionately held emotion-based anti-intellectual opinions that conflict with ‘better judgment based on unbiased investigation and thoughtful consideration in pursuit of learning to be less harmful and more helpful to Others’. However, it is well understood that many people can tragically be tempted to passionately fight to embrace and preserve emotion-based opinions, regardless of their ability to learn that they are harmfully incorrect.
Many people who understand the importance of rapidly ending climate change impacts are likely to vote against that rational understanding because of a more powerful harmful desire for Other emotion-based opinions excusing poorly justified harmful Interests.

MA Rodger at 22:43 PM on 8 August 2024On Hens, Eggs, Temperature and CO2
Keith R @14,
You are correct that the Koutsoyiannis paper does not assess the on-going +2ppm/yr of CO2 resulting from fossil fuel use (less the ocean and biosphere draw-down).
But your comment has goaded me into a back-of-fag-packet assessment of how much out-gasing the wobbles in the global temperature record would actually achieve. (I'd reckon beforehand it would be exceedingly tiny.)
If the last ice age saw CO2 rise by about 100ppm and global temperature rise about +4ºC, that would suggest a big El Niño-induced temperature rise of +0.4ºC would see CO2 rise 10ppm but only if equilibrium was achieved (which would take about a millenium).
An El Niño temperature wobble is up-&-down in a single year so there is of course no equilibrium. The out-gasing would be greater earlier and quickly tail off: say 50% happening in the first century, so 5% in the first decade and 0.5% in the first year? That would suggest an out-gasing CO2-rise resulting from a +0.4ºC temperature rise in temperature following a big El Niño of just 0.05ppm.
The actual CO2 wobbles the Koutsoyiannis paper relies on being temperature-induced out-gasing (and not drought-induced reductions in forest growth) are about 1ppm. So "exceedingly tiny" is a good description. -
Keith R at 20:51 PM on 8 August 2024On Hens, Eggs, Temperature and CO2
Here’s a simple way to look at the Koutsoyiannis paper… It claims that the data from 1980-2019 has correlations demonstrating that temperature changes drive CO2 and no correlation supporting CO2 driving temperature. He then concludes that this proves CO2 changes can’t drive temperature changes. There is a leap here from not seeing an effect in a 39-year period to the conclusion that it doesn’t happen.
The temperature drives CO2 side of the relationship occurs when something else such an El Nino, solar cycles, etc. causes a temperature change which causes a change in the degassing rate from oceans and that causes CO2 levels to change. These events occurred during the 39-year period and are shown in the Koutsoyiannis analysis.
The CO2 drives temperature side of the relationship occurs when something causes the CO2 concentration to change which modifies the strength of the greenhouse effect and this changes the temperature. Humans were emitting CO2 at a steadily increasing rate during the 39-year period and it is not clear that there were any changes in the rate of CO2 emissions that were significant enough to cause the temperature shift that would be detectable by Koutsoyiannis.
The mechanism used in the paper to look at shifts in the moving difference between values and the previous 5-year average will not detect a steadily increasing CO2 concentration causing a steadily increasing temperature. The paper is focused on the cause-and-effect of shorter-term fluctuations. The paper only shows that all the short-term changes during the monitoring period were the result of temperature changes driving CO2. The claim that this proves CO2 doesn’t drive temperature is unjustified. -
Doug Bostrom at 13:39 PM on 8 August 2024What Project 2025 would do to climate policy in the US
It's notable that the Heritage Foundation is keeping details of the so-called "fourth pillar" of Project 2025 a closely held secret.
Although we cannot identify its exact composition, we can think of the fourth pillar as a cylinder of compressed public policy gas to quickly fill the vacuum created by an incoming president with no interest in or knowledge of public policy.
With no organic competence in forming an administration, this person is an ideal pipeline for delivery of the Heritage Foundation's crafted payload. A uniquely dangerous person but ultimately a uniquely gullible type of chump, considering the relatively picayune takings he'll enjoy from his success compared to the enormous collective monetary advantages to be afforded his handlers by successful implantation of their scheme.
"The fourth pillar of Project 2025 is our 180-day Transition Playbook and includes a comprehensive, concrete transition plan for each federal agency. Only through the implementation of specific action plans at each agency will the next conservative presidential Administration be successful.
Pillar IV will provide the next President a roadmap for doing just that."
The details are presumably too ugly and controversial to disclose lest they cement the failure of the carrier candidate.

That level of water chemistry is not needed to convey or understand the concepts of equilibrium and lead/lag for CO2 and temperature. It would be needed to go on to explain acidification or total dissolved carbon.

Charlie Brown @ 669:
One needs to be careful about referencing Henry's Law when it comes to CO2. CO2 does not just dissolve in water - it ends up dissociating and forming carbonic acid. This complicates the solubility equations.
SkS has a very good series on ocean acidification - in 20 parts. The 9th part discusses Henry's Law. The entire series is summarized in the 19th and 20th posts in the series.

Charlie_Brown at 07:37 AM on 7 August 2024CO2 lags temperature
When considering lead/lag with CO2 and temperatures, there are two fundamental concepts to understand. One is Henry’s Law that dissolved CO2 in water will reach equilibrium with CO2 concentration in the air. The other is the overall global energy balance. At steady state equilibrium, nothing changes. Change occurs when there is an upset in the equilibrium. Major ice ages are caused by the major Milankovitch solar cycles which upset the energy balance. During the onset of ice ages, water gets colder and CO2 dissolves. The reduced greenhouse effect of lower CO2 concentrations allows more radiant energy loss to space. At the end of an ice age, CO2 evolves, reducing energy loss to space. This is the first time in the history of the planet that anthropogenic greenhouse gas emissions have upset the equilibrium CO2 concentration in air first. This time, the overall global energy balance has been upset by greenhouse gases rather than by responding to changes in solar irradiation.

The previous Koutsoyiannis paper that MA Rodger refers to - "On Hens, Eggs, Temperatures and CO2: Causal Links in Earth’s Atmosphere" - was subject to an analysis by Giacomo Grassi, in a guest blog post here at SkS in late May.
Koutsoyiannis has a habit of repeating the same errors paper after paper after paper, so I doubt there is much point in trying to read the entire "new" paper. In the abstract, he once again concludes "unidirectional causality", which defies physics. The abstract implies that he is using the same "stochastic methodology of assessing causality" that has been shown to be wrong before.
A key issue, buried in MA Rodger's reply to you, is that they use detrended data - ΔT and ΔCO2 - which hides the current cause of CO2 rise (steady input of CO2 from burning fossil fuels).
There are links to other discussions of previous Koutsoyiannis works on the SkS blog post (and comments) I link to in my first paragraph.

Blusox69 at 22:00 PM on 6 August 2024CO2 lags temperature
Thanks for the replies so far. I read the paper over a few times and it didn't sit right with me. Under section 4.1 he neglects to show data or even graphs for the CO2 to T as he states they "did not provide useful results". Straight away that rang alarm bells. I've never omitted data from my studies, even if the results were not useful as it lays the foundation for being accused of cherry picking data/results. I'm not a statistician, but I'm sure the same logic would be applied to their work too.

Blusox69 @664,
The paper you link-to is Koutsoyiannis (2024) 'Stochastic assessment of temperature–CO2 causal relationship in climate from the Phanerozoic through modern times' which is hot off the press. The author should immediately ring alarm bells being a known perveyor of crazy denialism.This SkS thread deals with the Temp → CO2 → Temp relationship prior to recent times when mankind began to increase atmospheric CO2 levels by burning fossil fuels and clearing forests.
The author of Koutsoyiannis (2024) also co-authored Koutsoyiannis & Kundzewicz (2020) 'Atmospheric Temperature and CO2: Hen-Or-Egg Causality?' which addresses a different relationship and does so with eye-bulging stupidity.
[To explain this stupidity, the measured CO2 record of recent decades has wobbles caused by El Niño impacting rainfall patterns and thus reducing vegitation growth in tropical regions. This effect is enough to slow the draw-down of CO2 and accelerate the atmospheric CO2 increase from human emissions, delaying the absorption of perhaps 15Gt(CO2) over a matter of months. Such a wobble is quite visible on the measured CO2 record. The whole process has been measurd from satellites.
An El Niño also causes a wobble in global average temperature and this temperture wobble arrives earlier than the CO2 wobble This is the situation Koutsoyiannis & Kundzewicz are measuring, a Temp wobble preceeding a CO2 wobble.
What Koutsoyiannis & Kundzewicz entirely fail to explain is the long-term rise in CO2 due to human emissions. This becomes eye-bulgingly stupid when they address the source of this long-term CO2 rise if it is due to rising temperature. They "seek in the natural process of soil respiration" and also "ocean respiration" but fail to actually look and find it. This should be no surprise. While warming biosphere and oceans would release CO2, the CO2 content of the biosphere & oceans is today increasing not falling, not exactly what you'd expect in a CO2 source.]I cannot say I have read Koutsoyiannis (2024) properly. After a lot of blather, it tells us it there are questions to be asked about the role of CO2 within the climate system. Is it a GHG? Is it "decisive" in this role? Is the GH-effect enhanced in the last century? Are human emissions increasing the GH-effect? Are human emissions "decisive" in this regard? Is mankind the cause of rising CO2 levels? Is CO2 increasing global temperature, or visa versa, or both?
Koutsoyiannis (2024) then lists a bunch of references to support the assertion that "conventional wisdom" is wrong although the science behind the "conventional wisdom" is rather unwisely (and unscientifically) ignored. Note that all nine of Koutsoyiannis's bunch of references is authored by Koutsoyiannis. He has, according to himself, managed to overturned the scientific understanding of our planet's greenhouse effect.And this new paper, Koutsoyiannis (2024), proceeds to use 12,000 words examining the temporal relationship between CO2 and global temperature for periods back 541million years. I have not read those 12,000 words but they certainly comprise more eye-waterlingly stupid blather.

Blusox69 @664 :
Are you referring to the new 10/July/2024 article by Dr Demetris Koutsoyiannis ? (your link is not activated)
If so, then you will find that some previous articles by Dr K. have already been discussed on the SkS website here.
IIRC, those articles showed gross errors in his understanding of climate physics. If you can show that Koutsoyiannis has made a large step forward in his understanding of climate mechanisms ~ then I (among others) would be happy to spend time analysing his new July paper. But you would need to make a good case that it wasn't just Dr K. seeking to recycle/republish his old erroneous ideas.
Over to you, Blusox69.
.
btw, the title of his new paper is: "Stochastic assessment of temperature-CO2 causal relationship in climate from the Phanerozoic through modern times". ~A rather discouraging title, which suggests that he is relying on a statistical analysis [which might well be misleading] rather than looking into the actual physical mechanisms which produce climate effects. Real science requires real demonstrated mechanisms of physical action.

during a recent discussion the below paper was mentioned regarding the lag of CO2 and temperatur. it's a very recent paper and doesn't pear to have been discussed on here.
I would like to hear your thoughts on it.

Responding to nigelj @12, particularly regarding skepticism of Trump’s denial of knowledge of Project 2025.
Trump winning appears likely to result in increased amounts of harmfully biased and noisy leadership judgment, especially if New Right Republicans win control of the House and/or Senate in addition to their already potentially very long lasting harmfully biased majority influence on judgments by the Supreme Court (SC).
This July 16, 2024, Inside Climate News article “Trump’s Environmental Impact Endures, at Home and Around the World” presents the legacy of actions by New Right Republicans last time they ‘owned’ the Presidency. And a significant part of that legacy is the ways the current day SC has continued to make harmful noisy biased judgments against everybody who is concerned about the future of humanity and learns to be less harmful and more helpful to Others.
Passionately held emotionally-based opinions can be aligned with better understanding that is developed through unbiased investigation and thoughtful consideration of how to be less harmful and more helpful to others. But in many cases the pursuit of better understanding results in changes and corrections that conflict with established passionately held opinions. Tragically, instead of learning, many people are easily convinced, susceptible to being conned into believing, that they are victims of attacks on their passionately held harmful misunderstandings.
The truth about what Trump will try to do if he is elected President appears to be exposed by this July 27, 2024, NPR article “Trump tells Christian voters they 'won't have to vote anymore' if he's elected”. Trump appears ready to try to lock in passionately held irrational misunderstandings as ‘what rules in the US’. The following quote appears to be Trump’s honest promise (in brackets are my clarification of more specific understanding regarding over-generalized terms misleadingly used by Trump).
"Trump also urged (fundamentalist anti-learning) Christians to turn out for him ahead of Election Day, calling it the "most important election ever." He added that if elected, (fundamentalist anti-learning) Christian-related concerns will be "fixed" so much so that they would no longer need to be politically engaged.
""You won’t have to do it anymore. Four more years, you know what? It’ll be fixed, it’ll be fine. You won’t have to vote anymore, my beautiful (fundamentalist anti-learning Caucasian only-English speaking) Christians," he said."That harmful promise by Trump is in addition to the additional harms his leadership would inflict on climate science understanding.
The New Republicans definitely appear determined to promote harmful misunderstanding to “fix” things in their favour on many important issues (like they “fixed” the SC) to the detriment of Others, especially to the detriment of all the future Others.
Paraphrasing nigelj's last sentence: Its all consistent with the New Right Republican interests in resisting learning to be less harmful and more helpful to Others.

MA Rodger at 20:43 PM on 1 August 2024It's Urban Heat Island effect
mihai @75,
The recent paper you refer-to Soon et al (2023) 'The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data' isn't that 'recent' and its content is likely 99% recycled from earlier offerings, it being the latest offering from Willie Soon and the Connolly brothers. (The phalanx of co-authors are likely no more than window dressing and not contributors to the work. It is not impossible that a fair few of them had no knowledge of this co-authorship.)
The main authors are "infamous" both for their climate denial and also their remarkable incompetence. They do however manage to string words together to create very lengthy papers, and in this case the offering comprised three lengthy papers (the other two here & here). As for the egregious error they have actually managed to incorporate into these particular offerings, that would take somebody to read through the drivel they present, no easy task when error is piled so high on error. Luckily, somebody has already done so, although for a detailed blow-by-blow rebuttal, there was a rebuttal of the rebuttal from Soon which was just as error-filled as the initial offering.

Reading OPOF's links, Agenda 2025 appears to be trying to forcibly restore an earlier version of America of the 1800's or earlier, where the traditional family was the model in society and was the only thing permitted, and you had very small government. There's nothing inherently wrong with the traditional familty of course, but but history shows this was a mean and nasty society with no care for human diversity, or government help for people who are struggling, and terrible economic depressions.
This was a system that was ultimately rejected by the vast majority of people during the 1930s period with its socio-economic reforms, that essenetially expanded the role of government and took a more compassionate view of people. Now the administrative state is under attack by the ultra conservatives..
Agenda 2025 sounds like something authoritarian and pretty close to fascism. The implications for the natural environment and limiting anthropogenic climate change are horrendously bad.
Fascinating that the writers prioritise freedom then want to forcibly impose the traditional family model on everyone and remove the freedom of choice to buy the abortion pill. The contradiction would go right over their heads. They are not exactly geniuses. They seem to have an aversion to diversity, and are very uncomfortable unless everyone conforms to a specific lifestyle.
Interesting how Donald Trump is distancing himself from Agenda 25. I suspect he is doing this because he knows it will be rejected by the majority, and so linking himself to it would damage his election chances. But make no mistake, once elected he will embrace virtually every aspect of Agenda 2025. Its all consistent with his values.
