rkrolph at 17:00 PM on 15 August 2023There is no consensus
I have been wondering lately if some of the more famous climate change skeptics, climate scientists like Judith Curry, have modified or adjusted their outlier positions as the global warming crisis grows worse year by year.
But apparently not, based on the article I read in the Torrance Daily Breeze by John Stossel, titled "The fake climate change consensus", that quoted her extensively, Most of the article I recognized as long ago debunked garbage, but it seems surprising to me that experienced climate scientists like Curry would still be promoting this kind of nonsense.

scaddenp at 14:26 PM on 15 August 2023Is Nuclear Energy the Answer?
I know next to nothing about nuclear reactors but I know coal-fired power stations well. When less power is needed then less coal is fed into furnace (making a mile of other adjustments especially to air flow and feedwater as well), so steam output is reduced. I would assume nuclear similarly slows output by slowing the nuclear reaction. To me, a partial shutdown is stopped one or more generation units not reducing steam output.
All steam plants have to reject heat back into the environment to convert steam back to water, usually by cooling towers. High summer temperatures play havoc with this especially if there are restrictions on temperature of cooling water going back into rivers. This usually means easier (and more efficient) to generate at night. If close to limit, then you have to reduce power as the day warms up.

Phillippe Chantreau,
My understanding is that many reactors stop generating electricity on weekends for economic purposes. Since France often has cooling issues on hot summer days, and they are reported to be in drought, a lack of cooling water could also contribute to less generation. If a reactor was off line both days for cooling issues it would not have registered in the data I copied (a good reason not to do your own analysis).
Here are my personal definations:
If a reactor is taken off line so that it no longer generates electricity it has been shut down. It does not matter what the reason is or if they keep the reactor hot so that it can be more rapidly started up again. I do not know the Wikipedia defination.
If a reactors power output has to be reduced for any reason that is a partial shut down and is an indication that the reactor is an unreliable power supplier. I note that nuclear supporters frequently claim that reactors are "always on".
What is your defination of shut down? If they insert all the control rods the chain reaction stops. The decay of radioactive fission products continues to produce a very large amount of heat. Enough heat to keep the boilers hot and requiring a large amount of water to prevent disasters. For me that is completely shut down but a nuclear technician might have a different defination.
Do you have a link that describes what the French do on weekends to lower nuclear power output by 20%? I would also like to know why they generate less power during the peak periods than during the low at night. I suspect waste heat is causing at least some of the decline (as you mention).
My understanding is that some reactors are taken below the critical level. The control of reactors is extremely complex so I could be incorrect.
The dates are from August 2023.

Doug Bostrom at 05:22 AM on 15 August 2023Do phrases like ‘global boiling’ help or hinder climate action?
Less guesswork may be needed than we may imagine. There's extensive literature on this topic. Try and then tweak "emotional language climate change communication" w/Google Scholar to get a foothold.
Susan Moser's work is especially helpful for getting the big picture of climate communications to the public. This slightly old synthesis by Moser is still quite useful: Communicating climate change: history, challenges, process and future directions.

Philippe Chantreau at 02:01 AM on 15 August 2023Is Nuclear Energy the Answer?
I would like participants here to clarify one thing: "shut down."
Growing up in France, I got to do school field trips to nuclear power plants. On these occasions, engineers would instruct us on basic elements of these plants' operation. A reactor is rarely "shut down" except for major maintenance or emergency/abnormal procedures. The reaction can be slowed, the reactor isolated from the rest of the system and/or generators taken offline, is that what we're talking about here? Otherwise it would imply taking the reactor below critical level and that is not practical if it is to be used again, especially on short notice.
Slowing down the reactor can be necessary when cooling is an issue, when the weaather is already hot and they want to avoid spilling too much warm water in the environment. This has become more of a concern as river water temperatures have been increasing. It could be why power output is higher at night in August. Unless of course, these dates are under European format, which would place them in October and May.

I posted this on another thread where questions were raised about nuclear.

I went back and looked at your link to French electricity generation where you claim: :
"This link from France's gov shows no such shutting down of nuclear on weekends.
https://www.rte-france.com/en/eco2mix/power-generation-energy-source#"
My emphasis. The days are not cherry picked, they are the only days I looked at. 8/10 is a Thursday and 8/5 is a Saturday.
date time Power MW

8/10 13:45 30424
8/5 4:15 28489
8/5 16:15 25548Several question about this raw data occured to me.
1) You state clearly that the data shows no nuclear power stations were shut down. Please explain why the power generated on the weekend is so much less than the power generated on Thursday. How does this show that no power stations were shut down over the weekend? It appears to me that about 6 of 31 power stations (20%) were turned off.
2) On both days they are generating more power at night when power is generated at a loss than they are generating during the day when the price of electricity is much higher. Can you explain why the "always on" nuclear plants generate less power during the most expensive part of the day than they do when electricity is cheapest?
This example proves beyond doubt that examining cherry picked factoids without any analysis is a complete waste of time. Please do not cite raw data any more. You need to cite analysis of data that filter out gross errors.

Eclectic at 09:16 AM on 14 August 2023It's not bad
Sorry, Jlsoaz @420 , but you would be on a Fool's Quest if you try to make the definitive Debunk of temperature-related deaths and suchlike measuring-sticks of what is (or isn't) an emergency or catastrophe. The idea you put forward is quite fundamentally flawed.
" Catastrophic" is a rubbery weaselword. Too much room for semantic sophistries & lawyerly one-sided advocacy & "Gotcha" public debating of incomplete truths. # Also there is the question of when to use catastrophe ~ is it only for right now today, or is it including major problems which are approaching us in the near- or mid-term future? ( Or the approaching Heat Death of the universe? )
Is it a catastrophe or calamity when you run your car off the road at high speed? . . . or only when your car overturns or strikes a large boulder, etc? Or is it like the old joke about the optimist who experienced the catastrophe of falling off the top of the Empire State Building ~ yet reassured himself by counting the number of floors he had fallen past without encountering a catastrophic outcome?
A fool's game there, Jlsoaz.
[ On side-note : It is not only "premature deaths" but also many other adverse effects that now (or in the future) can be consequences of AGW. In particular the "temperature-related deaths" that show up in studies of heat-related vs. cold-related deaths are rather poorly-documented for comparison purposes. Cold-deaths are usually well-documented, while heat-related deaths are rather poorly documented because they tend to occur more in a Third-World country, where the deaths are poorly recorded in cities & slums . . . and in the remoter regions, may not be recorded at all (in any medical/official assessment). ]

Hi -
As has been remarked by others, arguably this "It's not bad" response is good, but may be trying to cover too much ground. In particular, I'm here to request that the team consider writing a response to the related or subordinate myth(s), which are in my opinion arguably the most important myths not yet debunked on this site, that
- nobody has died from climate change,
- any claim of increased deaths can't be attributed to climate change.
- and, therefore, calling this a "climate emergency" is exaggerating, alarmist and hysterical.
I believe the science here would fall in the area of social science or biological sciences (i.e.: discussing increased mortality above what is expected per time period, and whether it is attributable, under established scientific practices, to climate change). There are peer reviewed publications out there which may give some idea and basis for a proper rebuttal, though admittedly we could use more of such publications to lean on in the face of such arguments. A couple of examples:
https://www.nature.com/articles/s41558-021-01058-x
Article
Published: 31 May 2021
The burden of heat-related mortality attributable to recent human-induced climate change1. I think these two links relate to the same study published in Nature in 2021:
LINK
Global Study Evaluates Heat-Related Deaths Associated with Climate Change
By David Richards
2.
Also in 2021, this may be a completely different study (I can't tell for sure at a glance. It seems to have been published in The Lancet Planetary Health.
LINK
World’s largest study of global climate related mortality links 5 million deaths a year to abnormal temperatures

---------
These above are just one or two recent examples. There are probably other credible-seeming ones if the team is able to look, in preparing a rebuttal, and they may vary as to which climate change impacts (heat, drought, rise in sea level, increased storms, etc.) have what mortality increase (or decrease, in some isolated cases, I suppose is possible) figures associated with them. As to "associated", I think it's to the scientific papers to clarify what the correct approach is.
Anyway, to simplify, please take a look at what I believe to be arguably the most important myth not yet addressed on this site.Moderator Response:[RH] Shortened and activated links. You can do this yourself in the future. Just look in the tabs above the text box.

You have still not linked the Jacobson et al report you claim to be citing. Perhaps it is this one.
In the paper you appear to be citing the analysis by Jacobson et al show that renewable energy can provide all needed energy for the entire world 24/7/365 with a monetary savings of approximately US$62 trillion per year (mostly health savings from reduced pollution). The system will be at least as reliable as the current fossil system. The supposed problems you claim to expose have been dealt with completely. Linking to cherry picked factoids with no analysis does not support your argument (and you provide no links).

You continue to insist that the industry standard terminology is misleading. If you do your homework you will be able to understand commonly used technology terms without confusion. Industry terms are intended for use by people who have read the backiground information and understand the meaning of the vocabulary used.
Your nuclear comments are off topic. World wide nuclear capacity factors are much lower than your cherry picked high years in the USA. 80% capacity factors is more the mark. France, the country that generates the highest fraction of their electricity using nuclear power, had a capacity factor of 51% in 2022. I addressed this in the post linked above.

michael sweet at 23:07 PM on 13 August 2023Is Nuclear Energy the Answer?
David-acct:
It is not my problem that you have not done your homework and do not know that France nuclear reactors shut down on weekends. From Wikipedia:
"France's nuclear reactors comprise 90 per cent of EDFs capacity and so they are used in load-following mode and some reactors close at weekends because there is no market for the electricity.[59][10] This means that the capacity factor is low by world standards, usually in the high seventies as a percentage, which is not an ideal economic situation for nuclear plants."
It is common knowledge among those who have done their homework that France generates too much nuclear power at night. They sell some at a loss to their neighbors (presumably those who use cheaper solar during the day). They shut down some reactors on the weekends since no-one wants the power.
In 2022 France generated approximately 279 TWh of nuclear electricity. Their installed capacity was 61.4 GW. I calculate their capacity factor at 51.8%. They forecast generating about 330 TWh in 2023 which gives a capacity factor of 61% in the unlikely event that they make their forecast. They have to shut down many reactors on hot days. Will that work with record hot summers?
Since nuclear reactors can't really load follow (in France they just shut them down on weekends), they generate too much power when load is low and not enough when load is high. They average out the daily usage in the data youo show so that it appears that they generate more usable power than they really do. They sell at night at a loss and buy during peak power at the highest prices. France uses their reactors differently than other nuclear countries because they were stupid and over built their reactor fleet.
They have limited storage so they turn off the reactors. In the USA the biggest pumped hydro storage plants were built to store nuclear power at night for use during the day peak. Nuclear supporters ignore the immense cost of storage for nuclear reactors while exaggerating the cost of storage for renewable energy.
No current scientific groups studying future energy systems recommend building any nuclear plants.
I recommend you read more background information (this thread would be a good start) so that you don't keep repeating long debunked nuclear myths.
Nuclear is too expensive, takes too long to build and there is not enough uranium.

John Mason at 10:58 AM on 13 August 20232023 SkS Weekly Climate Change & Global Warming News Roundup #32
One issue we all have here is just what constitutes 'doomerism'? It's a term that is currently thrown around too loosely.
One man's doom is another's bad weather day, after all. The ultimate picture is that Earth and biodiversity will survive the human age. We know that through the fossil record. Evolution will once again fill any gaps it can over a few million years. That has happened time and again through the deep past.
So putting that aside, it's about - as Katharine Hayhoe's book title clearly states - saving us! In that case, 'doomerism' needs a very clear definition, for I do not think there is such a thing at present. -
nigelj at 08:11 AM on 13 August 20232023 SkS Weekly Climate Change & Global Warming News Roundup #32
Regarding "With Temperature and Other Climate Extremes Shattering Records, Should We Call it 'Global Boiling'? 'Weirding'? Or...? by Tom Yulsman"
The idea discussed is that too much doomy rhetoric demotivates people. This is correct. It can have a deadening effect on people where they give up on contemplating solutions and habituate to the doom and just choose to live with the problem as best they can, like people in a war zone frequently do.
If there is any doomy rhetoric, its important to at least offer people solutions.
Another idea discussed is that creating too much climate fear is not a good thing.This is different from doomy rhetoric. However fear is a natural human motivator. We are hardwired genetically to feel fear when threatened and this generally motivates action. We communicate threats to each other that will cause fear and motivate action. This is all psychology 101. So its absurd to suggest we should somehow soften rhetoric to not make people fearful. This would be a dangerous manipulation that could backfire. It would not even be accurate.
However if the climate threat is innacurately described or exaggerated to try to cause fear this could backfire horribly because its likely the innacuracies or exaggerations will be exposed. We also cant solve problems effectively If we dont state them as accurately as possible neither understating or overstating a problem.
The reasons for the slow pace of climate action are probably not so much the way the threat is communicated anyway. Most people must know the basic problem by now and the scientists consider it serious, unless they have been living under a rock for the last 25 years. The reasons for slow progress are many and varied but one issue is we are psychologically hardwired to respond most urgently to immediate threats (like a wild animal attacking us) rather than slowly unfolding future threats like climate change even if they are very serious. Given climate change is now being more present and dramatic this might start motivate more change. Reference:
Other reasons are raised by people like OPOF to do with many leaders in society being reluctant to make lifestyle changes or support carbon taxes, because they are very addicted to materialistic displays of wealth as status signals.
However these problems do suggest to me we should try to motivate people to make changes by putting a lot of focus on the wider benefits of climate solutions, like EV's being more reliable cars, less reliance on imported petrol, cleaner electricity generation, etcetera.This is actually probably why renewables are gaining some traction.
Daniel Glick says " In communicating about that threat, we’ve tried terms like global warming, global weirding, climate emergency, and now global boiling." And he asks if any of this gets through to people and motivates people to make changes.
I can only give my gut reaction. Global warming - accurate. Climate emergency - a bit too colourful for me and people easily dismiss it as an exaggeration by giving examples of obvious dramatic and very present emergencies like Ukraine war. Global boiling - quite good. Nobody with any sense takes it literally, but this sort of satirical hyperbole might resonate with people. It does with me. Global weirding - accurate.
Just call anthropogenic climate change what it is: a huge problem for reasons xyz but that we have viable solutions.

I agree the cranks are a small subset of denilaists and that many of the denialists are fundamentally driven by selfish and economic motives. However you should add political motives to the list, being an ideologically motivated dislike of government rules and regulations. Of course these things are interrelated.
I have a bit of trouble identifying one single underlying cause of the climate denialism issue. It seems to be different denialists have different motives to an extent, randging from vested interests, to political and ideological axes to grind, to selfishness, to just a dislike of change to plain old contrariness. Or some combination. But if anyone thinks there is one key underling motive for the denialim I would be interested in your reasoning.
The cranks are not all deniers as such. Some believe burning fossil fuels is causing warming but some of them think other factors play a very large part like the water cycle or deforestation. A larger part than the IPCC have documented. They unwittingly serve the hard core denialists cause. They are like Lenin and Stalins "useful idiots."
I do visit WUWT sometimes, and I know what you are saying.
"To very broadly paraphrase Voltaire : It is horrifying to see how even intelligent minds can believe absurdities."
Voltaire is right. Its presumably a lot to do with cognitive dissonance. Intelligent minds are not immunue from strong emotively or ideologically driven beliefs and resolving conflicts between those and reality might lead to deliberate ignorance. Reference on cognitive dissonance:
www.medicalnewstoday.com/articles/326738#signs
This does suggests cranks might be driven by underlying belief systems not just craziness.

Eclectic at 11:06 AM on 12 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Nigelj @17 :
Cranks or crackpots do inhabit the Denier spectrum, But IMO they are outliers of the main body. Dr Frank's wondrous "Uncertainty" simply produces absurd results ~ see his chart showing the envelope of uncertainty which "explodes" from the observation starting point, rendering all data nearly meaningless. Yet he cannot see the absurdity. He falls back on the bizarre argument of uncertainty being separate from error. (But in practical terms, there is a large Venn Diagram overlap of the two concepts.)
WUWT blog is an enjoyable stamping ground where I observe the denialists' shenanigans. Most of the commenters at WUWT are angry selfish characters, who do not wish to see any socio-economic changes in this world ~ and hence their motivated reasoning against AGW.
Certainly, WUWT has its share of cranks & crackpots. Also a large slice of "CO2-deniers" who continually assert "the trace gas CO2 simply cannot do any global warming". (WUWT blog's founder & patron, Anthony Watts initially tried to oust the CO2-deniers . . . but in the past decade he seems to have abandoned that attempt.)
Dr Frank's comments in a WUWT thread are worth reading, but sadly they rarely rise above the common ruck there. Much more interesting to read, is a Mr Rud Istvan ~ though he does blow his own trumpet a lot (and publicizes his own book "Blowing Smoke" which I gather does in all ways Smite The Heathen warmists & alarmists. Istvan, like Frank, is very intelligent, yet does come out with some nonsenses. For instance, Istvan often states mainstream AGW must be wrong because of reasons A , B , C & D . And unfortunately, 3 of his 4 facts/reasons are quite erroneous. He is so widely informed, that he must know his facts/reasons are erroneous . . . yet he keeps repeating them blindly (in a way that resembles the blindness in Dr Frank).

A few points to clarify context - Using gross capacity factor is misleading since it greatly overstates the projected electric generation as noted by the except below from the US energy department.
https://www.energy.gov/ne/articles/what-generation-capacity
Capacity factors allow energy buffs to examine the reliability of various power plants. It basically measures how often a plant is running at maximum power. A plant with a capacity factor of 100% means it’s producing power all of the time.
Nuclear has the highest capacity factor of any other energy source—producing reliable, carbon-free power more than 92% of the time in 2021. That’s nearly twice as reliable as a coal (49.3%) or natural gas (54.4%) plant and almost 3 times more often than wind (34.6%) and solar (24.6%) plants.
When comparing capacity factors, its important to fully understand the different reasons why each type operates below their capacity ratings. Fossil fuel generation has greatly reduced generation below capacity during the spring and fall when demand is the lowest, while achieving much higher rates of capacity when needed in the winter and summer. Whereas, Wind and solar produce at or near capacity when weather conditions are optimal. You have to compare apples with apples
-
nigelj at 07:51 AM on 12 August 2023At a glance - The tricks employed by the flawed OISM Petition Project to cast doubt on the scientific consensus on climate change
I agree with NP.
It may also be about the term catastrophic which I believe is a strawman. Because climate science never claimed at that time that heating would be catastrophic, which is a colourful, imprecise, loaded term that many may associate with billions dying very fast. Science claimed anthropogenic warming will cause very serious problems xyz, and cause a significantly increased mortality rate in the tropics.
So its understandable that a petition saying there is no convincing evidence of catastrophic heating of the atmosphere would get plenty of signatures. If the petition had just said there is no convincing evidence of serious problems it probably wouldn't have got nearly as many signatures.
But by using a strawman the denislists got plety of people to sign and thats what people notice more than the significance of the word catastrophic. Dont be fooled by the denialists tactics.

MAR @14. Good points.
Franks "wondrous theory" does indeed sound crazy. What mystifies me is how a guy with a Phd in chemistry, thus very highly scientifically literate could get relatively basic things like that wrong. Because its fairly well doumented that the up and down variation in year to year temperatures is due in large part to a component of natural variability cycles. And he does not seem like a person that would dispute the existence of natural climate cycles.
It makes me wonder if he hasnt actually read much background information like this on the actual climate issue - and perhaps feels he is such a genius that he doesn't need to. Yet this would be astounding really that he is unaware of short term climate cycles and cant see their relevance. I do not have his level of scientific training by a long way, but its obvious to me.
It seems more likely he is he just being crazy about things for whatever reasons and this craziness seems to be the main underling characteristics of a crank. But their frequent narcissim means no matter how much you point out the obvious flaws they just go on repeating the same theories, thus their nonsense certainly compounds over time.

Your unsupported claims also have no merit.
Renewable energy is the cheapest electricity in the world. While the turbines and solar farms cost billions to build, they saved more billions when gas prices went up. Carbon Brief has several articles where they analyze the enormous amounts of money saved by renewable energy and document that "cutting out the green crap" in the UK ended up costing consumers billions more when gas prices went up. Simply stating how much it costs to build renewaable installations without considering how much low cost electricity is generated is deceptive.
Battery storage currently competes on cost with gas peaker plants. Battery costs are rapidly decreasing. Batteries will replace all peaker plants due to economics in the near future.
You argue that wind energy at night is wasted (without any citations to support this wild claim) and then say that nuclear, which cannot be turned off at night, is the way to go. That is a direct contradiction that negates your argument. In France nuclear generation is only 70% of nameplate because they have to close up on weekends. They sell nuclear electricity at a loss at night.
Nuclear supporters like you ignore the fact that nuclear requires at least as much storage as renewable energy does. The largest pumped hydro storage facilities in the USA were all built to store nuclear electricity generated at night. This is a second contradiction in your arguments that negates your claims.
In any case, nuclear is too expensive and there is not enough uranium to build a significant amount of nuclear.

Dav8id-acct:
Everyone knows that new build power supplies are rated by maximum capacity to generate. You are simply arguing semantics when you object to the industry standard.
I note that you have no citations to support your claims.
The Jacobson et al paper you cite with no link concludes that a fully renewable system using batteries at the current cost would be the cheapest way to generate future energy. He finds that there will be no problems supplying electyricity 24/7/365. Renewable energy that produces 20% of rated capacity is the cheapest electricity in the world. Your unsupported claims have no merit.

Nick Palmer at 22:24 PM on 11 August 2023At a glance - The tricks employed by the flawed OISM Petition Project to cast doubt on the scientific consensus on climate change
I've always thought that the exact wording of the Oregon Petition
"no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing or will, in the foreseeable future, cause catastrophic heating of the Earth's atmosphere and disruption of the Earth's climate"
was grammatically constructed to actually have been technically signable AT THE TIME OF FIRST LAUNCH even by such climate luminaries as James Hansen.
It comes down to the artful use of "is causing" and "will cause" - instead of 'may cause' - catastrophic heating and disruption etc. The petition does not state that its wording assumes that mainstream climate science was asserting that emissions will continue to rise sharply and that climate sensitivity to CO2e was at the top end of published expectations back then (somewhere around 6°C per doubling if I remember, although 10°C was mentioned https://skepticalscience.com/climate-sensitivity-advanced.htm ) but it is the underlying insinuation (of the text) that climate science was saying these things that enables the rhetorical deceit inherent in that exact wording. It allows any scientist who was fairly familiar with the science back then to jump to the conclusions that, because such emissions rises weren't certain to take place, and that ensemble figures for climate sensitivity were showing a 'most likely' figure of ~3°C per doubling, then it was definitely not certain that 'catastrophic heating' would occur. -

I was interested in what the two reviewers listed actually said. I couldn't find it. Wunsch is highly unlikely to have given it a 5* review and I don't think Zanchettini, who is much less well known, would either.
The reason it would be helpful to know is that Frank's recent '23 paper and its past incarnations, such as '19, are currently being promulgated across the denialosphere as examples of published peer reviewed literature that completely undermines all of climate science. If one knew that Wunsch and Zanchettini had both said seomthing like 'the overall construction of the paper was interesting but has some major logical and statistical flaws in it', and Frontiers in Science had decided to publsih it anyway, that would be very useful anti-denialist 'ammo'. -
MA Rodger at 18:52 PM on 11 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Nigelj @13,
The paper Frank (2019) did take six months from submission to gain acceptance and Frontiers does say "Frontiers only applies the most rigorous and unbiased reviews, established in the high standards of the Frontiers Review System."
Yet the total nonsense of Frank (2019) is still published, not just a crazy approach but quite simple mathematical error as well.But do note that a peer-reviewed publication does not have to be correct. A novel approach to a subject can be accepted even when that approach is easily show to be wrong and even when the implications of the conclusions (which are wrong) are set out as being real.
I suppose it is worth making plain that peer-review can allow certain 'wrong' research to be published as this will prevent later researchers making the same mistakes. Yet what is so often lost today is the idea that any researcher wanting publishing must be familiar with the entirety of the literature and takes account of it within their work.
And for a denialist, any publication means it is entirely true, if they want it to be.In regard to the crazy Frank (2019), it is quite simple to expose the nonsense.
This wondrous theory (first appearing in 2016) suggests that, at a 1sd limit, a year's global average SAT could be anything between +0.35ºC to -0.30ºC the previous year's temperature, this variation due alone to the additional AGW forcing enacted since that previous year. The actual SAT records do show an inter-year variation but something a little smaller (+/-0.12ºC at 1sd in the recent BEST SAT record) but this is from all causes not just from a single cause that is ever accumulating. And these 'all causes' of the +/-0.12ºC are not cumulative through the years but just wobbly noise. Thus the variation seen do not increase with variation measured over a longer period. After 8 years in the BEST SAT record is pretty-much the same as the 1-year variation and not much greater at 60 years (+/-0.22ºC). But in the crazy wonderland of Pat Frank, these variations are apparently potentially cumulative (that would be the logic) so Frank's 8-year variation is twice the 1-year variation. And after 60 years of these AGW forcings (which is the present period with roughly constant AGW forcing) according to Frank we should be seeing SAT changes anything from +17.0ºC to -12.0ºC solely due to AGW forcing. And because Frank's normal distributions provides the probability of these variations, we can say there was an 80% chance of us seeing global SAT increases accumulating over that 60 years in excess of +4.25ºC and/or decreases acumulating in excess of -3.0ºC. According to Frank's madness, we should have been seeing such 60-year variation. But we haven't. So as a predictive analysis, the nonsense of Frank doesn't begin to pass muster.
And another test for garbage is the level of interest shown by the rest of science. In the case of Frank (2019), that interest amounts to 19 citations according to Google Scholar, these comprising 6 citations by Frank himself, 2 mistaken citation (only one by a climatological paper which examines marine heat extremes and uses the Frank paper to support the contention "Substantial uncertainties and biases can arise due to the stochastic nature of global climate systems." which Frank 2019 only says are absent), a climatology working-paper that lists Frank with a whole bunch of denialists, three citations by one Norbert Schwarzer who appears more philosopher than scientist, and six by a fairly standard AGW denier called Pascal Richet. That leaves a PhD thesis citing Frank (2019)'s to say "... general circulation models generally do not have an error associated with predictions"
So science really has no interest in Frank's nonsense (other than demonstrating that it is nonsense). -

"In 2020 wind generation of uk output was 25%, remember though that includes night time generation that went to waste. "
I wonder if thats accurate. Because when demand for power is very low, I recall reading somewhere that wind farms get turned off. So I would think the 25% of generation would only include when the turbines are actually generating power. I stand to be corrected if anyone can post a link saying otherwise.

I alway like to be able to cross check against the source data. The 25% generation of capacity in the UK from solar seems slightly high given UK's latitude.

nigelj at 07:37 AM on 11 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
I enjoyed Bob Loblows article because it did a thorough debunking and I learned some things about statistics.
Some of the errors look like almost basic arithmetic and I thought a key purpose of peer review was to identify those things? They did an awful job. It looks like they didnt even bother to try.
Regarding whether such papers should be debunked or not. I've often wondered about this. Given the purpose of this website is to debunk the climate myths it seems appropriate to debunk bad papers like this, or some of them. It would not be possible to address all of them because its too time consuming.
There is a school of thought that says ignore the denialists because "repeating a lie spreads the lie" and engaging with them gives them oxygen. There is some research on this as well. There has to be some truth in the claim that responding to them will spread the lies. It's virtually self evident.
Now the climate science community seems to have taken this advice, and has by my observation mostly ignored the denialists. For example there is nothing in the IPCC reports listing the main sceptical arguments and why they are wrong, like is done on this website (unless Ive missed it). I have never come across any articles in our media by climate scientists or experts addressing the climate denialists myths. The debunking seems to be confined to a few websites like this one and realclimate.org or Taminos open mind.
And how has this strategy of (mostly) giving denialists the silent treatment worked out? Many people are still sceptical about climate change, and progress has been slow dealing with it which suggests that giving the denialists the silent treatment may have been a flawed strategy. I suspect debunking the nonsense, and educating people on the climate myths is more important than being afraid that it would cause lies to spread. Lies will spread anyway.
A clever denialist paper probably potentially has some influence on governments and if its not rebutted this creates a suspicion it might be valid.
However I think that actually debating with denialists can be risky, and getting into actual formal televised debates with denialists would be naieve and best avoided. And fortunately it seems to have been avoided. Denialists frequently resort to misleading but powerful rhetorical techniques (Donald Trump is a master of this) that is hard to counter without getting down into the rhetorical gutter and then this risks making climate scientists look bad and dishonest. All their credibility could be blown with the decision makers.

Eclectic @7, agreed overall.
I didnt mean to imply all cranks are narcissists or lean that way. It just seems to me a disproportionately high percentage of cranks are narcissists. It's just my personal observation but the pattern is rather obvious and striking. I tried to find some research on the issue but without success.
Perhaps the crank tendencies you mentioned and narcissism are mutually reinforcing.
And remember narcissists do frequently come as cross as nice, normal likeable people, just the same as sociopaths (psychopaths) often do. They find this front works best for them. In fact they can be especially likeable, but its about what lies beneath and eventually one notices oddities about them, or in their writings, and if you get into a close relationship with them it can end very badly. Have seen some ciminal cases in the media.

MA Rodger @ 9:
It is an open question whether it is better to ignore papers such as Pat Frank's most recent attempt, or spend the time debunking it. I chose to debunk it in this case, but to paraphrase Top Gun, "this is a target-rich environment". There are so many logical inconsistencies in that 46-page tome that it would take weeks to identify them all. Just trying to chase down the various references he uses would require months of work.
I took this as an opportunity for a "teaching moment" about propagation of uncertainty, as much as an opportunity to debunk Pat Frank. Thanks for the reference to Lenssen et al. But what Pat Frank needs to do is start with a Statistics 101 course.
Nick Palmer @ 10:
I'm sure the general answer to your question is "yes", but I did not try to chase down every blog post and link in the lengthy chain exposed by the linked post at ATTP's. I did read parts of some, and remember that some of his earlier efforts to publish involved open review.
Nigelj's comment that some people "...are unable to ever admit to themselves or others that they are wrong about something..." seems particularly true about Pat Frank.

Correction ~ my apologies Davz. If the UK's 40 million vehicles use 2 gallons of lubricating oil per year each . . . then the wind turbines are using only about 1% of that (not the 10% figure I mentioned above).
-
Eclectic at 04:43 AM on 11 August 2023Just how fast will clean energy grow in the U.S.?
Davz @3 , you are quite right that it is only the actual production of electricity that should be stated. Like you, I am irritated by public announcements of XYZ generation capacity newly installed . . . when it would be more honest to quote the actual effective generation (which is in the 15-30% range, for various wind & solar).
Since you have used UK figures (rather than the OP's North American bias) ~ there we see wind turbines supplying around 20-25% of electricity needs. Planned turbine growth will exceed expected growth of UK electricity needs.
The UK usage of lubricating oil is an interesting topic. Davz, on your figures the oil usage by wind turbines is close to 10% of the lubricating oil used by the UK's 40 million vehicles. More turbines = more oil, and yet more more electric vehicles = less lubricating oil. A nett advantage for EV's (and that also ignores the fuel oil used by ICE vehicles).
Davz, please check the figures for lubricating oil used by nuclear plants ~ on the little that I have seen, it is reported that "nuclear" uses a much higher oil amount per MegaWatthour than does coal / gas / wind turbine. And then there is the problem of nuclear's huge costs & very slow build times (but I presume you know that).
Costs of batteries is red-herring. When wind turbines are over-producing electricity, the turbines are feathered or stopped down. Future battery costs . . . who knows? . . . but the technology is leading to much lower prices. Eventually, a small household battery may get to the price of a household refrigerator.
# By the way Davz, please return to your comment on another thread, where you suggested that climate warming had no way of contributing to increased wilfires. It would be ethical of you to discuss your point further ~ or acknowledge that you were wrong.

MA Rodger at 02:40 AM on 11 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
I'm not sure Frank is responsible for 'propagation' or the spreading of nonsense. He is the creator of nonsense that others happily spread. But strangely the remarkable level of stupidity achieved by Frank and other denialists is not an issue for those who spread such denialist messages, or those who happily receive them.
As for debunking Frank's crazyman attack on climatology, this debunking can be achieved in many ways. There is plenty of opportunity as the man is evidently heavily in denial over AGW and stupid enought to feel he is able to prove that his denial-position is correct while the whole of science is flat wrong.
I'm not of the view that climbing down the rabbit hole to chase his nonsense round down in the wonderland world of Pat Frank is the best way to debunk Fank's lunacy. (I talk of 'chasing his nonsense' because his latest published serving of nonsense is an embellishment of work now a decade-plus old while a whole lot different from his nonsense from four years back featured in the video linked @4.) Yet this SkS OP is attempting such a chase.Frank's obvious stupidity does lend itself to debunking although his embellishments with lengthy coverage of associated stuff in this 2023 paper provides him a means of obfuscation. In such a situation, I'd go straight for the conclusions, or in Frank's latest paper 'final' conclusions.
So Frank agrees that there has been warming since the 19th century (as shown by phenology which certainly does indicate "unprecedented climate warming over the last 200 years, or over any other timespan" has occurred in recent decades). But generally Frank's paper would suggest the instrument temperature record cannot show any warming. Indeed having told us of the phenological "direct evidence of a warming climate" he then tells us "The 20th century surface air-temperature anomaly, 0.74 ± 1.94 °C (2σ), does not convey any knowledge of rate or magnitude of change in the thermal state of the troposphere." That 0.74 ± 1.94 °C (2σ) surely suggests a 23% chance that measurement of actual temperature represents a cooling not a warming, with a 5% chance of a cooling of -1.2 °C or more.
And really, if anybody were attempting to question the accuracy of the global temperature instrument record, it would be sensible to start with the work already done to establish such accuracy, eg Lenssen et al (2019). But Frank seemingly doesn't do 'sensible'. -
Davz at 01:12 AM on 11 August 2023Just how fast will clean energy grow in the U.S.?
All sounds great until a realistic analysis of the energy creation in countries that have invested billions into clean energy and it's not all it's cracked up to be. Here in the UK we have over 12000 wind generators, mostly off shore. The amount of energy they create looks on paper to be a reasonable return on the investment until you start looking at the numbers. The issue is that generating the electricity carries on through the night and these figures are used by the govt to mislead the tax payer as the energy from the night isnt required, the vast majority of the population are asleep in bed. It would be great if the energy could be stored but the cost of batteries is at the moment twice the gdp of the uk! In 2020 wind generation of uk output was 25%, remember though that includes night time generation that went to waste. In 2021 generation was 7% as the wind didn't do its job. So to compensate for years the wind doesn't blow the Uk would have to invest in at least 100k wind generators and batteries for storage, that would cost many times more than gdp.....completely unaffordable. Then we have the problem that each wind generator Requires 80 imperial gallons of oil every year for lubrication, if the whole world invests in wind farms oil will still be needed. The only realistic solution is nuclear.

This article describes the massive increases in new electric generation from solar installations by noting the huge increases in solar "capacity" including the following quotes:
"....project that the U.S. will install about 63 gigawatts of new solar capacity by the end of 2024"
" the record 24 gigawatts of solar capacity added in 2021 will likely be broken in 2023 "
Gross increases in solar capacity should be read in full context. If one is going to discuss increases in electric generation from solar, one should be using realistic numbers. As noted by Jacobson in his study of 100% renewables, the US actual solar generation is approx 20.8% of capacity . See his table S11 in his recent 2022 study. Canada actual generation from solar is slightly less at 18% of capacity and Europe is only 17.6% of capacity. Also note that the winter months, the northern US and Canada the electric generation from solar is in the range of 10% or less of capacity.
Below is a link to the German electric generation by source. Note that during the summer months, solar generates 12k GW's -15k GW's daily, while in the winter months, the electricity generated from solar ranges from 1k GW/s -4k Gw's and often falls below 1k GW's.

If only we could expand wind and solar as fast as China has.
In 2020 they installed 72 GW of wind and 48 GW of PV solar.
In 2022, they installed another 37.6 GW of wind and 87.4 GW of solar.
In just the first two months of 2023 they installed over 20 GW of solar.
But then, I think they have invested a lot in HVDC long distance transmission lines. -

Nigelj @8 , you are correct about some of the characters that you yourself encounter at RealClimate blog. Psychiatrically though, the WUWT blog presents a "target-rich environment" for a wider range of pathologies. And Dr Pat Frank is still to be seen making brief comments in the WUWT threads . . . but mostly his comments match the run-of-the-mill WUWT craziness stuff, rather than relating to the Uncertainty Monster.
Anecdote ~ long ago, I knew a guy who had spent a decade or more tinkering in his garden shed, inventing an electrical Perpetual-Motion machine. Continual updates & modifications, but somehow never quite hitting the bullseye. He had a pleasant-enough personality, not a narcissist. But definitely had a bee in his bonnet or a crack in his pot [=pate]. R.I.P.
And the Uncertainty Monster still lives in the darker corners of public discussion. Living sometimes as a mathematical nonsense, but much more commonly in the form of: "Well, that AGW stuff is not absolutely certain to six decimal places, so we ought to ignore it all." Or existing in the practical sphere as: "It is not certain that we could eventually power all our economy with renewables & other non-fossil-fuel systems . . . so we should not even make a partial effort."
