John Hartz at 09:55 AM on 17 February 2023Skeptical Science New Research for Week #7 2023
By coincidence, Greta Thunberg adresses CCS head-on in a recently (yesterday) published Op-ed that I today posted a link to on the SkS Facebook Page. A key pragraph from Thunberg's Op-ed:
"Also, the carbon-removal facility in Iceland has some serious scaling up to do. Yet that is clearly not happening, which makes no sense at all. Why foster the idea that this underdeveloped technology could be a substitute for the immediate, drastic mitigation needed? Why bet our entire civilization on it without making the slightest effort to make it work? Why make the world picture a potential solution so vividly that we include it in every possible future scenario and then fail to invest in it? Could it be that it was never even meant to work at scale? That it was just being used — once again — as a way of deflecting attention and delaying any meaningful climate action so that the fossil fuel companies can continue business as usual and keep on making fantasy amounts of money for just a little while longer?"

ubrew12 at 04:16 AM on 17 February 2023The Problem with Percentages
"renewable energy grew 25% in a single year, recent, historical trends indicate that the growth of renewables is not even keeping up with growing, global energy demand." Global energy demand may be accounted in terms if 'fossil energy in' rather than 'electricity out'. As mentioned a week ago on this website, 60-70% of 'fossil energy in' is lost as waste heat upon combustion, the remainder becomes electricity. For fossil energy, the 'energy in-to-power out' conversion is as low as 30%. For renewable energy, it's closer to 80%.

RichardBryan at 17:55 PM on 16 February 2023The escalator rises again
I asked someone to think about climate related trends in terms of what a stock market chart might look like. People can immediately picture and understand that a stock price which declines over the course of a year would nevertheless have periods of days or weeks or months wherein the price was rising and falling and rising and falling, only to close lower at the end of the year. So when looking at charts describing levels of atmospheric carbon dioxide, or surface air tempertures, a short segment in the middle of the graph won't be an accurate representation of what's happening (i.e., a global warming "pause"); looking at the long term is what matters. People intuitively understand stock market charts and I've found this analogy to long term climate changes to be helpful in day to day conversation.

John, Baerbel, Ken & Doug:
I have been sifting and winowing through the internet for more than a decade now to identify quality news articles about manmade climate change and related matters.* During this time, I have seen a signifigant growth in debunking articles generated by journalists, scientists, blog authors, and others.
One such article was posted just two days ago. It is:
Myth-buster: Why two degrees of global warming is worse than it sounds by Daisy Simmons, Climate Explained, Yale Climate Connections, Feb 13, 2023
In the context of the rebuttal update initiative described in the OP, I thought it would be interesting to see which of the Skeptical Science (SkS) rebuttals Simmons' article best pairs up with. It appears that would be the SkS rebuttal, #3 It's not bad.
Having said the above, the existing SkS rebuttal, #3 It's not bad covers almost the complete universe of climate science. Therefore, the best Advanced version of the rebuttal would in essence be the most recent scientific report of the IPCC.
My basic recommendation re this ball of wax is to slice and dice the the SkS rebuttal, #3 It's not bad into distinct chunks.

Bob Loblaw at 23:40 PM on 15 February 2023Climategate CRU emails suggest conspiracy
The Climategate and Peer-review link I gave above is #95 on SkS's "Most Used Climate Myths". (This thread is # 17.)
If you really want to read about corruption of the peer-review process, you should look at # 205 on the list: "How contrarians used pal review to publish contrarian papers". In the contrarians' world it is easy to imagine that the mainstream climate scientists are corrupting the process, because that's exactly what the contrarians are willing to do when they have control of a journal. Accuse your opponent of doing what you are doing...

JonJC @85 ,
the Climategate biz is rather ancient history by now ~ but the science-denialists are desperatey short of ammunition . . . so they have to keep dredging it up (and they can never admit they got it wrong).
My favorite discussion of it is by science journalist "Potholer54" , back in about 2010. Google his youtube video titled "Climate Change - Those hacked e-mails".
His video runs 9 minutes, and you will find it amusing as well !

Judith Curry recently did an interview on Jordan Peterson's podcast - and she still leans very heavily on Climategate.

If you're not across it I'll suffer through listening to it again and will provide a summary - please let me know if you'd like me to do this. -

ubrew12,
Well presented point about the fundamental, and glaringly obvious, harmfully misleading nature of the proponents of fossil fuel use.
I would go one step further, to be more general. Harmfully misleading promotion of fossil fuels is part of the larger developed collective of harmful misleaders regarding so much more.
There are other harmful impacts of many of the things 'harmful misleaders' want people to 'fear not being able to continue to believe, desire and enjoy'. In almost every case there is a less harmful, but more expensive, alternative that does not require 'petroleum'. In every case it is possible to enjoy life with less of the 'promoted consumption'. And in many cases it is possible to enjoy life without the 'developed desires'.
The reality is that almost everything 'unnecessary but desired' today could be obtained less harmfully at a: higher cost, lower level of convenience, or reduced perception of superiority. That reality contradicts the developed interests of a person who has allowed themselves to be fooled and indoctrinated into 'desiring' understandably harmful beliefs and related actions.

Eclectic at 23:24 PM on 13 February 2023Global warming: a battle for evangelical Christian hearts and minds
EddieEvans @55,
there's a large number of Dr Curry's own articles (among others) to be seen on her blog "Climate Etc" (at judithcurry.com) . But you may find it rather tiresome to wade through a good sample of them. Her modus operandi is to be vague & misleading to the naive/layman reader, by throwing up clouds of maybe & could-be & might-be.
At first glance you might feel that she is being a cautious scientist, in keeping her mind open to possible alternative explanations for modern global warming. But as you look at her track record and persistent line of do-nothingism "until we are really truly exactly sure of the precise amount of warming which is anthropogenic if any" . . . then you see that her AGW policy is in lock-step with the Oil Lobby. Basically she is a propagandist who seriously distorts mainstream climate science, in her own unique way. Plus a smattering of grievance about her persecution by those dreadful mainstream scientists (i.e. the 99%) .
# Thank you for the 2019 article you link to. A short but interesting article, authored by an economist Guy Sorman [age 78]. Sorman seems to have genuine virtues personally . . . though being an Old School free-marketeer (the Market is the solution to all problems).
However, Sorman has re-hashed much of Dr Curry's usual blend of half-truths and misleading information ~ great grist for his "conservative" readers of that City Journal for which he is a contributing editor ( I gather ). But very bad science.

Those same people declare that it is unacceptable to ridicule people who present understandably ridiculous beliefs. They have a ridiculous belief about community-building. They believe that community-building requires acceptance of harmful people who want to promote and prolong harmful misunderstanding.

I received an email from an old acquaintance mired in conspiracy theories. An article, Climate Science’s Myth-Busterboosting, by Judith Curry.
Would anyone share a remark about “findings”? I see that SKS has much about her past denialism.

Jim Hunt @1314 ,
Judith Curry's denizens are, as you well know, much uninclined to engage with you in any true sense. They tend to operate by deflections and faux misunderstandings. (Commenters Joshua, Willard, and David Appell are very much the exceptions ~ but they appear rarely.)
The Curry-ites are somewhat more upper class than the WUWT-ites, on the whole. But you may have noticed that many of them have a sort of Schroedinger Feline brain ~ you cannot be certain whether inside the cranium is something which is brain-dead or brain-alive. Or a brain which is both at the same time, or is rapidly alternating. This might explain how so many of them know that you [Jim Hunt] are correct in what you have (so often) said to them in the past . . . and yet they usually seem ignorant of that information (and are not wishing to know it).
BTW Jim, with my newest VPN version, I do not get to access your website GreatWhiteCon.info ~ stuff comes up like "cannot access this site" or "this site does not support https". Presumably the fault is mine as a computer ingenu . . . but would you mind checking your https status ? Thanks. [No need to reply]

Jim Hunt @1314,
The reference to "Brave New World" is noted. But it can be understood to be the "Same Harmful Old World".
There is currently a resurgence of people demanding the promotion and protection of harmful misunderstandings that excuse understandably harmful developed aspects of the Status Quo. Many people dislike learning that excuses of harm done are misunderstandings. They resist learning evidence-based evaluations done in pursuit of limiting harm done and developing sustainable improvements.
What is seen to be happening regarding Twitter and other media, and clearly dominant in politics, can be well explained as follows:- People who want to prolong harmful misunderstandings demand that presentations of harmful misunderstanding must be 'protected freedom of thought and expression'
- Those same people declare that it is unacceptable to ridicule people who present understandably ridiculous beliefs. They have a ridiculous belief about community-building. They believe that community-building requires acceptance of harmful people who want to promote and prolong harmful misunderstanding. Ridiculing people who persist in resisting learning to change their mind about harmful misunderstandings is deemed to be 'harmfully divisive'.
The future of humanity requires this cyclical resurgence of harmful selfishness to fail. Ultimately what is required is social transformation that limits the harm of attempted resurgence of harmful selfishness. But, unfortunately, as the climate science case proves, the current system is substantially compromised by harmful selfishness. It allows a lot of harm to be done by the promotion and prolonging of harmful misunderstandings. And climate science is not the only matter where more harm is being done due to the ‘ridiculous freedom of harmful selfish people to believe and do whatever they desire and resist being restricted and corrected by Others’.

As blind chance etc. would have it I currently find myself engaging with Judith Curry's denizens under her article about the recent joint venture with Jordan Peterson.
This is presumably the cause of some or all of the "it's the sun, stupid!" nonsense currently being promulgated in the Twittodenialosphere?
As a consequence my Arctic alter ego felt compelled to bring the following NASA article to the attention of one such Dunning-Kruger sufferer:

MA Rodger at 19:14 PM on 12 February 2023It's the sun
Philippe Chantreau @1312,
While Curry is evidently referring to the ACRIM gap of 1989-91 when she talks of "a gap in the satellites measuring the sun's output that occurred at the time of the Challenger shuttle disaster" of 1986, mainly because there is no other "gap". But her reference to AR6.6 'Short-lived climate forcers' as giving discussion of some "great uncertainty in the amount of solar forcing in the late 20th century" that "arises" from the ACRIM gap is deluded nonsense. AR6.6 concerns aerosol forcing and thus the solar aspects of this and nowhere considers any gaps in TSI data.
As you say, the ACRIM gap was an issue of long ago although I think it remains an issue when used in historical proxy TSI reconstructions and whether the Maunder Minimum TSI was 1Wm^-2 or 2Wm^-2 lower than today. But this is not apparently what was Curry attempting to describe in her deluded rant. (The graphics below are from an Andy May discussion of TSI dated 2018.)

MA Rodger @1310 , thank you for extracting some classic Curry.
I particularly liked :- "... huge amounts of [solar] variability ... a lot of issues related to UV and stratosphere and cosmic rays and magnetic fields and ... things that really aren't being factored in [to models] ..."
A quote so typical of Dr Curry. A bit of smoke & mirrors, vague handwaving, followed by more sciencey-sounding vagueness, plus the magic word Uncertainties uttered thrice. And at this point, every Denialist is nodding in agreement, with all critical abilities set in the OFF position. Her style is unique.
If Dr Curry were pressed on some of that nonsense, she would walk it back ~ by retreatiing into more vagueness. She outclasses Dr Peterson in that way ~ he at least can look slightly embarrassed when he is caught out in some of his own nonsenses (and he does, when caught, walk his mistakes back . . . temporarily).
Dr Curry's style of discourse reminds me somewhat of another speaker, but she has never actually suggested fixing solar problems by injecting bleach into the sun.
-
MA Rodger at 02:10 AM on 12 February 2023It's the sun
The link given @1305 leads me to a bunch of YouTube adverts but if you specify a time with the link, the Curry/Peterson nonsense appears. Thus:
https://www.youtube.com/watch?v=9Q2YHGIlUDk&t=60s
Below the video there is a box that can be expanded with a 'show more' tab and that shows a list of a couple of dozen parts to the video (called Chapters) and one of these does mention things solar (which was what panhuag @1306 was asking about) 'The Challenger explosion, how the sun affects climate'. This provides the following from Curry:-"Once you get into the sun, it's even crazier. The IPCC has pretty-much dismissed the role of the sun in the last 150 years but the interesting AR6.6 finally acknowledged the great uncertainty in the amount of solar forcing in the late 20th century and this arises from ... a gap in the satellites measuring the sun's output that occurred at the time of the Challenger shuttle disaster... So one solar sensor was running out and they were supposed to launch another one but all the launchers were put off for a number of years until they sorted out... (the launchers). So there's a so-called gap which depending on what was happening in that gap, you can tune the solar variability to high variability or low variability. So all the climate models are being run with low solar variability forcing.
For the first time in AR6.2 (2.2.1), the observational chapter acknowledges this issue, that there are huge amounts of variability.
And this doesn't even factor in the solar indirect effects.... It's not just the heat from the sun. There's a lot of issues related to UV and stratosphere and cosmic rays and magnetic fields and all these otehr things that really aren't being factored in. They're at the forefront of research but they're certainly not factored into the climate models so there are so many uncertainties out there that affect certainly the projections of what might happen in the 21st century but also our interpretation of what's been going on with the climate for the last 100 years and exactly what's been causing what.A quick look at AR6.2.2.1 shows Curry is doing particularly well ast spouting nonsense here.

Thanks for the words of encouragement in your comment @11.
I plan to continue to be 'anonymous' on the internet. As an anonymous participant I have no copyright on the thoughts I share. I am still learning from others and I am happy to have others adopt aspects of what I share as part of their learning.
I agree with your current understanding that significant social change is required to limit the harm done by misleading pursuers of personal benefit. Without that social change harm will continue to be done by pursuers of status and personal benefit. A 'technological transition' that appears to address the climate change problem could end up being like putting new wall-paper on the walls of a dwelling that is continuing to rot, be burned-out and be pest-infested, but the walls will look nicer - for a little while.

- The web software here does not automatically create links. You can do this when posting a comment by selecting the "insert" tab, selecting the text you want to use for the link, and clicking on the icon that looks like a chain link. Add the URL in the dialog box.
- The Comments Policy specifically states "Any link or picture should be accompanied by text summarizing both the content of the link or picture, and showing how it is relevant to the topic of discussion. Failure to do both of these things will result in the comment being considered off topic." As Rob Honeycutt states, just providing a link without much context is just sending people off on a wild goose chase, and is considered bad form.
- The link does work for me, but the first two names that I see are Judtih Curry, and Jordan Peterson. Neither are particularly reliable. Details on Judith Curry are available here and here. She has a reputation for beating the Uncertainty Drum as if it was a rented mule. Jordan Peterson has no background in any sort of atmospheric science, let alone climate science. You can read more about him here.
If you wish to continue this line of thought, you are going to have to provide some sort of coherent discussion and argument.

please do not go over to WUWT to point out their problems. There is already a (very) small number of scientific commenters in the WUWT threads, but they are continually shouted down by all the loons, goons, and crackpots (including the intelligent Willis Eschenbach and Rud Istvan).
The scientific commenters there are clearly getting some pleasure from tweaking the Denialist noses, yet they do not (and cannot) bring enlightenment to the denizens of WUWT. But their comments are worth reading in themselves ~ and I enjoy reading them, and I manage to stomach (or skip over) the comments by the crazies who oppose them.
There is a Schadenfreude to be had in viewing the statements by the crazies ~ it is challenging & interesting to recognize & unravel their logical errors and motivated reasonings. That gets tiresome rather quickly, though.
# Thank you Bob, for your statistics criticism. My own education stopped at Statistics-101 and has rusted since ~ so I cannot do much more than apply common sense to what I see at WUWT. And it is always impressive how *determinedly* the WUWT-ites refuse to use common sense in their thinking.
[Excuse repeated scathing of WUWT ~ but WUWT deserves no less.]

bobhisey at 05:34 AM on 10 February 2023Clean energy permitting reform needed to boost economy, protect climate and burn less coal
The recently available NASA satellite of infra-red transmission of earth's radiation clearly shows that no energy is escaping the earth in the wavelength range where CO2 can effectively absorb it. (The 14-16micron range). Thus there is no energy left in this range for more CO2 to absorb!
So the whole "decarbonization" effort is an exercise in futility! All the models seen are thus fatally flawed and should be junked on sight.
Green energy is a massive misallocation of resources. More should be spent to find the true cause of global warming.
See NASA Technical Memorandum 103957, Appendices E and F.

Bob Loblaw at 01:44 AM on 10 February 2023The escalator rises again
I don't have the stomach to go over to WUWT, but the author of this blog post has also reposted it on his own blog, and here have been some interesting comments over there.
Willis Eschenbach, of WUWT fame, has commented, and posted a graphic of what he calls "an actual structural breakpoint analysis" for the period 1969 to now. He draws attention to the steps, claiming "this is not done by 'cherry picking' but by mathematical analysis, this brings up the interesting question … what is causing the jumps?".
Spolier alert: the "jumps" are an artifact of an inappropriate statistical analysis, and Willis has no explanation of any physical process to explain them, other than a brief hand-waving about El Nino events. But let's entertain the possibility for a bit.
I pointed out in the comments over at ATTP's that the month-to-month change in the anomalies (i.e., this month's anomaly minus last month's) shows absolutely nothing to suggest that the anomaly goes through any sort of slow change (as suggested by the linear segments) interspersed with sudden jumps. If you take the entire BEST record, this is what you see for the month-to-month change in the anomalies:
The month-to-month change in anomaly looks pretty much like random noise to me. If Willis' hypothesis of meaningful "jumps" existed, I'd expect to see periods of fairly steady (i.e., unchanging) anomalies, with periodic short episodes of large changes representing "jumps" No such structures appear in the data.
I also took the information from the graphic Willis posted of his "structural breakpoint analysis" and added the six line segments he created to a graph of the 1969-present BEST anomalies. This is a reproduction of that information from Willis' graph:
The point I made over at ATTP's is that Willis six-segment linear fit to the data provides virtually no additional statistical explanation of the overall data. The equation on the above graphic is the basic linear fit for the entire data set. Note that the r2 value is 0.81. The regression standard error is 0.145 C - indicating the remaining "unexplained" variation in the residuals from the regression.
How much better does Willis do with six line segments (and five breakpoints)? Not much. The accumulated standard error from the six regression lines is 0.133C - just over 0.01C better than the simple fit.
If we look at some statistics for the six segments, we get:
End Year Standard error P-value R^2 1976.8 0.131 0.07 0.0353 1986.9 0.141 0.764 0.0008 1994.7 0.141 0.25 0.0143 2001.8 0.137 0.376 0.0095 2014.9 0.119 0.005 0.0504 2022.9 0.137 0.126 0.0001 The P-values do not account for auto-correlation (there is lots), so take them with a grain of salt. But only one of Willis' line segments looks remotely significant, and the r2 values are very low.
The fact is that nearly all of the statistical explanation in Willis' analysis is in the jumps, but there is no reason (looking at the month-to-month changes) to expect this analysis to come up with anything that is not just a misrepresentation of the noise.
A basic linear regression does almost as well, with only two parameters (slope and intercept). In Willis' analysis, he needs 17 parameters: six lines (slope and intercept = 12 parameters) and five break-point years. This is not particularly parsimonious.
Splitting a gradual increase in the data into a bunch of "jumps" that are a function of noise may be entertaining, but it's not particularly scientific.

Eclectic at 13:12 PM on 9 February 2023The escalator rises again
The (Monckton) thread comments count is now up to 566. The monthly Moncktonian review of the New Pause has always been a very "popular" thread for the denizens at WUWT. This one, with over 500, is probably well above its usual level ~ but I am not going to bother to check back through the past 12 months of records there.
(A) As usual, Monckton turns a blind eye to Ocean Heat Content
(B) The long term UAH data trend continues to rise.
(C) The Monckton thread commenters have many wrangles about what constitutes statistical significance +/- confidence levels +/- Dr Pat Frank's peculiar ideas of Growth of Uncertainties. What many of them seem to have forgotten, is that this is not a case of statistical analysis of an abstract set of figures, but an analysis of physical events where the underlying causations are known.

MA Rodger at 05:59 AM on 9 February 2023The escalator rises again
I think Monckton was using RSS TLTv3.3 for previous rants flat warming trends. He now switches to UAH TLTv6.0 although the wobbly nature of the TLT record is the cause of this nonsense (not the slow rate of TLT warming) and which record you use thrugh recent years (since 2005) doesn't make a significant difference. I think using RSS TLTv4.0 would today only provide a 100-month of flat trend.

Everyone wanting to better understand the required ‘transition’ should read the Report that is discussed in the Story of the Week. That would help develop the awareness and understanding of the required transition to most effectively limit harm done and develop sustainable improvements.
A key point is that ‘Social Transition (socioeconomic-political systemic change)’ is required. Technological transition without that systemic change is likely to be the most harmful pathway (the BAU case). ‘Climate problem solutions’ developed by the BAU socioeconomic-political system would be harmful in many ways. The harmfulness of the technological transition can be severe if the focus is on the perceived climate change harm done by energy use. Other harmful impacts of energy use could be ignored or excused.
Reduced energy consumption, limited to ‘necessary consumption’, with a transition to less harmful energy systems, all harms considered (not just climate impacts), is the least harmful ‘solution pathway’. What has developed is significant ‘unnecessary energy use’. And a lot of harm reduction, not just climate impact harm, can be done almost immediately, and could have happened 30 years ago, without technological improvements. That significant, but essential, ‘social transition’ is required to limit the harm done to the future generations.
The ‘resistance to reduced consumption and responsibly learning to be less harmful’ by many wealthier people, and people who aspire to be like them, through the past 30 years has created the current situation. The situation is now more harmful than it needed to be. Indeed, because the current situation is more harmful, the ‘responsible transition to limit the overshoot of 1.5 C impacts and bring impacts back below 1.5 C’ could involve changes that some current day people would see as ‘draconian reductions of their developed perceptions of success and limits on their opportunity for future perceptions of benefit’ (for some people, any external limitation of their freedom to believe and do as they please is Draconian).
A related point is that the harm of 1.0 C of warming is significantly unacceptable. Arguing that 2.0 C warming will not produce significant risk of unstoppable feedback is an example of the problem of ‘promoting the positives to the detriment of consideration of the negatives’. It needs to be understood that an overshoot of the 1.5 C target is a serious problem that requires rapid correction to limit the harm done. It can be argued that future generations will make the required correction. But that argument is a harmful misleading systemic BAU ‘kicking the can down the road’ cycle-of-harm argument. It is understandably important to break the systemic cycle of ‘excusing harm done because of the opportunity for benefiting from being more harmful’.

Eddie and Slum... Are you both aware that the 2°C limit is at least partially predicated on the fact that was how warm the Eemian interglacial got? There are reasonable assumptions that under 2°C the climate system would not set off feedbacks that send us toward far higher temps. There are also reasonable assumptions that the actions that are taking place can put us on a path to keep the earth at or below 2°C.
The challenge before us (humanity) is truly massive. Yelling that the ship isn't turning fast enough doesn't change its direction. Real energy solutions do. Positive support for those solutions does. Barring the use of private jets does vitually nothing. Putting a price on carbon so that flying in those jets comes in line with the damages they impose, along with all other FF uses, does.
The technical solutions for successfully transitioning off of FF's are already here. They're continually being improved upon. Spreading rhetoric that the game is already lost is doing the bidding of the FF's industry, because when people believe all is lost they give up trying. And that's exactly what the FF's industry wants.

Sorry, but even "ground all airplanes, set a date for outlawing the use of private fossil fuel vehicles, eliminate industrial animal agriculture, place a moratorium on the manufacture of cement, and diminish all forms of international trade that require any form of physical transport."
The rich and powerful will continue to march on paving over earth until they too bottom out. I'm watching CO2 ppm climb and people are arguing over bedroom ethics.
