MA Rodger at 01:01 AM on 23 August 2022There's no tropospheric hot spot
Cedders @33,
On boosting search rankings, the promotion from page 1,000 up to page 900 because a URL is used a single timesomewhere on the inerweb in my view is not very significant. If you want to give your webpage a proper boost, you'd use other means. But saying that, I do get criticised occasionally for using denialist URLs and thus boosting their rankings (and I am no expert in the matter). You can apparently make such a use without any boost whatever using the 'nofollow' extention in the HTML of a URL (but I'm not sure how you'd use that in the SkS URL inserter).On the URL content, I haven't looked down that URL yet. And it is useful to take the whole argument thus presented (so I 'look forward' to all 24 pages of it) as one approach to dismissing a difficult bit of debunking is to point to all the obvious nonsense argued alongside the difficult debunking. This is of course an ad homenem logical argument but without the difficulty being resolved (one way or the other) it is not in any way a logical fallacy.
On atmospheric cooling from CO2, the equilibrium in the energy balance will be restored following a CO2 forcing. This would result in the troposphere warming by +1ºC per 2xCO2 increase (without feedbacks) which will act over the whole blackbody emissions spectrum of 7.5 to 100 microns, this balancing the +3.7Wm^-2 forcing from the CO2.
When it comes to the CO2 forcing itself, CO2 emissions only acts over a small part of the global emissions spectrum. See fig 5b3 of that useful paper Zhong & Haig (2013) 'The greenhouse effect and carbon dioxide' which shows the spectrum of a CO2 increase 389ppm to 878ppm (2xCO2 from 2013) and how the central micron of the emissions are already past the tropopause and thus cooling the planet rather than warming it. Thus the 3.7Wm^-2 CO2 forcing comes from a rather narrow part of the spectrum 13¼ micron to 16¾ micron (less that central 14½ to 15½ now operating to cool the planet). To make this narrow band have such a big effect, it has to result from a cooling of the emissions altitude, a cooling far bigger than the average that would be required over the full blackbody spectrum. So that emissions altitude increases on average enough to perhaps give you 10ºC drop in temperature.
Do note that the CO2 emissions will be reaching space from vastly different altitudes. The central part of the emissions are up in the stratosphere while the edges of the emissions will be low down in the troposphere. The bits inbetween the edge and the centre will thus stretch all the way up. So this effect will apply to the whole troposphere.
So the emissions altitudes post forcing will rise and thus become cooler by a far bigger amount than the compensating warming of the troposphere to reach post-forcing equilibrium. And that cooling will drop the emissions into space. So any diural temperature variation due to loss of daytime solar warming will be less due to this cooling/drop of IR emissions.
On the significance of this cooling. Meanwhile, because the emissions altitude is higher, there will be a drop in the pressure of the emissions altitude although only for the O2 & N2. The extra CO2 will presumably mean CO2 will be effectively constant. And this drop in pressure will mean a drop in the air's Specific Heat Capacity. (The temperature effect on SHC will be pretty flat.) And this drop in SHC will mean that for a constant loss of energy through the night, any diurnal cooling will be larger. This then operates in the opposite direction to the reduction in IR caused by the cooler emissions altitudes which will lower the energy loss and thus reduce the diurnal range.
And so the question is which effect is the larger? Indeed, are they of a significantly similar size? And given that, is the effect significant for the diurnal temperature range?
Given the proposal comes from this denialist URL, that is perhaps the first place to look for answers. So I will be looking at those 24 pages (although prior to that my own very cursory work on the first two of those questions suggests the pressure/SHC is the larger effect with a ration of 3:1).
I hope all that makes sense.

I completely agree with you that everyone should read the literature to become fully informed.
I my world, with acquisitions and product purchases and other testing we perform due dilegence - a variation of "peer review" with the primary difference is that real money is involved so we strive to get it right. Not that in academia, there are negative consequences are not as bad if you get in wrong.
one of the reasons I provided the link to EIA was because it is an excellent unbaised source for electric generation by source on a real time basis for all the grids in the US.
That being said, I reviewed Jacobsons paper from oct 2021, along with his paper from 2015. I also read the critique of jacobson's work published in june2017 by pnas. His updates are basically minor modifications to his 2015 study/analysis. All his papers are quite dismissive of the hurdles associated with storage and the frequent doldrums associated with renewables.
When comparing and contrasting his analysis of how to deal with the intermitiancy of wind, he glosses over any hurdles. None of his proposals come close to addressing engineering hurdles such as the the event of Feb 2021 in a coherent / reality based manner. I refer back to the EIA which shows the combined electric generation from wind and solar in ercot grid was down 60-90% for 8-9 days , the SWpp grid lost 70% for 6 days. the MIso grid lost 50-90% for 14 days. the MICO grid was also near collapse that the Ercot grid experience.
I have re inserted the link to the EIA . gov website so that other readers of this website can review the SOURCE data.
You can select the time period and grid using the star wheel link in the upper right corner
again I appreciate your comments - especially to become informed - especially to become fully informed and to perform the necessary due diligence to reach an independent unbiased conclusion

Cedders at 07:42 AM on 21 August 2022There's no tropospheric hot spot
Thanks to you both for trawling through this. I was wary that linking to the document might boost its search engine ranking, but here it is via archive.org (16 of the 24 pages in the printed version). It doesn't have the professional gloss of a Heartland publication, but any documentation with one or two specious arguments helps some members of the public justify their preferred position.
Both papers look useful in understanding important features of atmospheric physics before thinking about how greenhouse forcings affect them. I'm not sure why search engines didn't find them for me; or maybe I was looking specifically for greenhouse effects. I find Seidel et al the easier of the two to read and providing the simplest rebuttal: there really isn't much diurnal temperature variation to influence OLR in any case. Gristey et al confirms 'diurnal temperature range becomes negligible at around 100 m altitude' (above surface), suggesting it's surface temperature that is most important in their Sahara example, followed by clouds and convection.
Gristey et al also suggests to me that the effect of increases in LLGHGs and specific humidity will reduce transmittance, so also reducing OLR coupling to surface 'hotspots' and further reducing what small diurnal range there is at, say, the tropopause. I am a bit confused why the OLR varies proportionately more over the day than the temperature at 500 hPa (Seidel fig 3), but suppose the atmospheric window (IR emitted from the surface that never interacts with atmosphere) is important.
On the logic of rising emission layers: 'Being thinner (less O2 & N2 but same CO2), it would presumably have a lower specific heat capacity, so for the same IR flux it would cool quicker,' - well put, that is where I thought there might be some merit in the new argument - 'but being at a higher/colder altitude it would be shooting off less cooling IR.' I wasn't convinced by that caveat, because shouldn't the OLR/cooling IR at the TOA remain what you expect at 255 K? So 'upper atmosphere adjusting quicker' might have a grain of truth in it, but adjusting to what (space mostly?), and doesn't it imply regressing to diurnal mean more quickly? In any case, there's no empirical support for increased diurnal range.'And in the literature I haven't heard of any consideration of the diurnal range up in the upper troposphere beyond cloud formation which suggests if there is some effect, it is all rather obscure.'
Very obscure, but that doesn't mean it doesn't serve the contrarian's purpose. I probably would never have thought about the 'hotspot' itself, not being prone to expeditions in high-altitude balloons or worried about that part of the atmosphere, were it not for various contrarians using the very lack of empirical data to argue for a flaw in established theory. These arguments are about fine details, emphasising them as if they were important, to distract from a central point that someone wants to avoid.

Further to Michael's comment, calling attention to an article highlighted in this very edition:
Hybrid Power Plants. Status of Operating and Proposed Plants, 2022 Edition, Bolinger et al, Lawrence Berkeley National Laboratory
Nonrenewables axiomatically have their own hard limitation and unreliability beyond intermittency: they're not permanent. When whatever it is that we're rearranging to extract energy is exhausted, that's it— that system is kaput for good.
If we're OK with a very brief phase of civilization as we'd like it, non-renewable (temporary) fuel is not a problem. If we'd prefer to be in the long game, we'll inevitably be running on 100% renewables.
Succinctly: resistance to renewable energy is not so distant from wishing for or even believing in perpetual motion.
Meanwhile, for the case of fossil hydrocarbons, the more we burn now the sooner the date at which we have to begin building HC molecules for all the other requirements they fulfill. And (no surprise) doing that requires a lot of energy. The more FF we burn now, the bigger our burden later. The sooner we choke off this error, the better. Calling building materials "fuel" is a bit stupid, after all.

JasonChen @18,
If it is a "demonstrable fact that certain factions within society are eager to see a Great Reset and enthusiastic about the climate agenda and the broadest, most disruptive approaches to emissions reduction," you do need to show it is a "demonstrable fact." Such a 'demonstration' requires a lot more than naming Musk, XR, BLM & AOC as exemplars of folk wanting "political change" and then baselessly assert they welcome the opportunity AGW presents. And to further assert that such folk have influence over the work of the IPCC and beyond into the science of climatology which is, you assert, being used to falsify that science, such assertion requires a lot more than you simply pronouncing on the level of this alleged influence "I don't know, but I certainly wouldn't assume the answer is zero." You do need to show in full detail the "IPCC assessment reports that subsume scientific findings and disputes under an advocacy narrative."
And if you can't do that, you need to go away and rethink your message which presently is reading like the message you'd hear buried in a DJT speech.

Bob Loblaw at 01:27 AM on 20 August 2022Water vapor is the most powerful greenhouse gas
Oh, darn. The moderator has pointed Likeitwarm to a place where the answers to my homework assignment can be found.
The infinite series I had in mind is:
1 + x + x*x + x*x*x....
or
1+ x + x2 + x3 ...
where x is the additional single-step feedback temperature rise added to the initial 1 degree rise. At each subsequent step, x acts on the extra rise from the previous step, hence the x2, x3 terms.
Brilliant mathematicians have managed to find a closed form (finite) solution to that infinite sum, for x less than 1.
sum = 1/(1-x)
As long as x < 1, there is an eventual stable sum. If x = 1, the denominator becomes zero and the sum becomes infinite. If x>1 the sum at each step represents an exponential increase.

Bob Loblaw at 01:14 AM on 20 August 2022There's no tropospheric hot spot
MA Rodger beat me to it. My quick Google search produced the same two papers that he has linked to and discussed.
The term "upper atmosphere" is vague. In the stratosphere, temperature increases with altitude, and increasing CO2 is expected to cause cooling, not warming. . In the upper troposphere, diurnal temperature range is small, and warming due to CO2 is also small.
The Seidel et al paper that MAR references says that upper troposphere diurnal range is <1K.
The Gristey et al paper indicates that factors such as cloud variations, humidity variations, and convective dynamics are dominant.
And I agree that the selected quote is largely incoherent. As for the author being related to a UK politician - that points to some obvious candidates with long records of obfuscation and poor science.

MA Rodger at 00:52 AM on 20 August 2022There's no tropospheric hot spot
Cedders @30,
You don't provide a link to the PDF of this pamphlet, assuming it is on-line somewhere. Given the quotes you provide, the pamphlet does appear to be verging on the incoherent, so the actual argument presented may not make a lot of sense and may easily be entirely unfounded.Indeed, I would guess that any talk of a CO2 IR mechanism is nonsense. Certainly I do not see any mention in the literature (eg Gristey et al (2018) 'Insights into the diurnal cycle of global Earth outgoing radiation using a numerical weather prediction model')
Considering the logic of it, the addition of CO2 to the "real atmosphere" does mean there are more photons flying about in the 15 micron waveband, but because there is more CO2, their 'flightpath' is commensurately shorter as there is more absorbing CO2 as well as more emitting CO2. O2 & N2 simply do not emit/absorb any IR themselves but do transfer energy to/from CO2 through collision which is a temperature thing.
The altitude where IR is shooting off to space will have the same volumetric concentration of CO2 and this altitude will rise upward as CO2 is added. Being thinner (less O2 & N2 but same CO2), it would presumably have a lower specific heat capacity, so for the same IR flux it would cool quicker, but being at a higher/colder altitude it would be shooting off less cooling IR. So I don't imagine a simple process worked out on the back of a denialist's fag packet.
And in the literature I haven't heard of any consideration of the diurnal range up in the upper troposphere beyond cloud formation which suggests if there is some effect, it is all rather obscure.And as you say, the surface diurnal temperature range reduces with an increasing greenhouse effect. The diurnal range is much smaller through most of the troposphere (see Seidel et al (2005) 'Diurnal cycle of upper-air temperature estimated from radiosondes') but the same principle (of increased insulation reducing nighttime cooling & thus the diurnal range at altitude) presumably still carries.
So without sight of that PDF, this effect would likely be very small if it does exist, and given the rarified atmosphere up there in the upper troposphere, don't hold your breath. -

I understand it's a polarizing, politicized issue, and conspiracy theory is a label that's easy to apply and minimizes cognitive dissonance. But that does injustice to the important scientific discipline of hypothesis generation, in which we come up with other potential causes for whatever evidence we observe and hold space for them. Without the commitment to any particular narrative or the paranoia implied by conspiracy theory.
It's demonstrable fact that certain factions within society are eager to see a Great Reset and enthusiastic about the climate agenda and the broadest, most disruptive approaches to emissions reduction. Industrialists like Mr. Musk have already made billions and expect to make many more in the green revolution. Extinction Rebellion and BLM and other Marxist groups are eager to see capitalism torn down, industrialization rolled back, and people suffering enough to support a communist revolution. Politicians like AOC are leveraging climate to propel their careers and justify sweeping political change. For these groups, climate change is not an inconvenient truth at all, it's just the opposite.
To what extent does the IPCC we see today, its output, the choices of which climate research gets funded and which papers get published reflect the influence of such factions rather than pure science? I don't know, but I certainly wouldn't assume the answer is zero.
What might we expect to see if such groups had significant influence, either at the formation of the IPCC or since? An IPCC charter that isn't strictly scientific but reaches into politics, a remit that isn't narrowly focused on some specific goals but one that's broad and vague. We might see IPCC assessment reports that subsume scientific findings and disputes under an advocacy narrative. Rather than push for narrow, achievable climate interventions like "build 1000 nuclear plants," it might instead go broad and endorse every conceivable intervention that might affect emissions, with vague nostrums like "climate justice" sprinkled in to curry political support.

I also got a kick out of the 'science the shit out of it' moment. It fit in the context of the movie and at that moment. Alluding to what he had to do with his excrement was very good.
In this presentation's context I see a connection to the 'hot as hell' consequences of less aggressive corrective actions. But the term seems out of place in the context of a presentation intended to 'appeal to everyone who might be inclined to want to better understand this issue'. Other terms that convey a required 'urgent emergency response' may be better.

Cedders at 21:46 PM on 19 August 2022There's no tropospheric hot spot
Hello again. I hope this is a reasonable place to post a potential new myth or misunderstanding related to the upper atmosphere, which I read in a pamphlet by a noted contrarian (brother of a UK politician; a PDF is online and an earlier version found on a Reading University student debating blog). The confusing tract is almost entirely myths already covered on SkS, confusions of carbon stocks and flows, graphs of Antarctic CO₂ lag, faulty logic of causation, a proposal that increases in atmospheric CO₂ are a reaction to the MWP and coming from the oceans, and an incomprehensible suggestion that back radiation doesn't conserve energy. Then it mentions lapse rate and emission layer displacement but that 'this model also says that with more CO₂ the upper atmosphere at a certain level will get warmer ... the hotspot turned out to be a coldspot!'
Now it's not clear how the auithor made that connection; maybe it was the both emission layer displacement and 'hotspot' involve temperature lapse rate. I understand, as explained on the intermediate page here, that the negative lapse rate feedback is due to increased evaporation and latent heat transport from warming oceans, not directly related to CO₂. The pamphlet then ventures three reasons for the alleged inconsistency of model with experiment, never mind that it's actually consistent: these include changes in lapse rate curve (actually the basis of the hotspot), that 'transpiration cooling by plants... increases with CO₂' (the reverse is true, surely?), and then something that I can't verify one way or the other:
In the real atmosphere there are day/night temperature fluctuations (eg in upper atmosphere). They are larger with more CO₂ because CO₂ (infra red absorber / emitter) gains & looses [sic] heat easier than N₂ & O₂ and so enables all the air to adjust quicker.
So translating into my terminology, the idea is that diurnal temperature range at the top of atmosphere increases with CO₂ and contributes to temperature heterogeneity, total outgoing flux and negative Planck feedback. As GHG concentration increases, the effective top of atmosphere rises to less dense air, correct? (Which means daytime air might lose a similar amount of energy initially, but cool faster but then need mixing from lower layers to continue the same radiative flux to space. Or something.) So could it be a valid interpretation? My reponse would be that any such effect is covered in GCM models, but it would be quite difficult to pull it out and quantify it as a separate effect. It seems it might be a small negative feedback on the first-order effect, but is the logic of the speculation sound? Diurnal temperature variation at the surface will decrease with CO₂: will it decrease or increase or stay the same at height? Thanks for any references or insight.

US Energy generation by source provided by the US Energy Information Administration is one of the best sources to understand the practical limitations of renewables.
A few things to note for the period July 1 2022 through Aug 15th which covered most of the US heat wave of the summer of 2022. Electric generation from wind was at the low point most every day for that 45 day period from late morning until evening with few exceptions.
The nice thing about the interactive chart is that you can select any grid in the US and select any time period, ( see the star wheel in the upper right of the chart which provides the options to change grids and time periods). Using that feature allows the individual to see any time period. That being said, one of the other data to see the the frequency of 2-3 day periods when electric generation from wind is in the doldrums.
So, even though the LCOE is considered to be low for wind, LCOE becomes meaningless with the wind doesnt produce or when it produces more than the grid can handle (

"What's not that list is physics goals of fixing the climate or even predicting it well. 30 years later, the climate is neither fixed nor on a path to be fixed. Fixed hasn't even been defined. The IPCC hasn't identified anything close to a seat belt. The response strategies it has formulated have a conspicuous overlap with Klaus Schwab's agenda for maximal disruption. Large chunks of the world are rejecting them as economically and politically unpalatable. These are just facts."
Your stream of mostly nonsensical, wrong, evidence free, citation free assertions is getting tiresome. I wish you would take your trolling somewhere else. You also have a habit of confusing various things.
For the benefit of sane people:
"What's not that list is physics goals of fixing the climate"
Fixing the climate is not a physics goal. Physics is about understanding the climate. Mitigation is about fixing the climate.
And The IPCCs stated goals of assessing the relevant scientific information obvious directly imply the requirement to understand the physics.And their stated goal of formulating response strategies is clearly about "fixing the climate".
"or even predicting it well"
IPPC does not predict the climate. It reviews predictions made in various modelling exercises and the predictions have been quite good:
"the climate is neither fixed nor on a path to be fixed."
The fact that the climate problem has not been fixed is nothing to do with the IPCC or some undefined nebulous global elite. Neither are tasked with fixing the climate problem. Its because governments have weak policies, corporates have been slow to respond, and individuals have been complacent.
"Fixed hasn't even been defined. "
Fixed has been defined: Net zero by 2050 under the Paris Accord Agreements. You may disagree with the definition, but stop telling people there is no definition.
"The IPCC hasn't identified anything close to a seat belt."
The IPCC have defined the science very well. Their latest report runs to about 10,000 pages and references many thousands of peer reviewed studies. The science goes back over 100 years. This website discusses this issue if you go through their menu system to find relevant information.
"Klaus Swabs agenda".
Jason you better put on your tin foil hat.
"Large chunks of the world are rejecting them as economically and politically unpalatable. These are just facts."
Large chunks of the world are rejecting climate mitigation strategies for a range of reasons. For some its because they don't want to pay any costs, but there are many other reasons including vested interests, holding on to establiashed patterns of a materialistic displays of status, campaigns of climate science denialism and for various psychological reasons. But equally large chunks of people want mitigation strategies implimented, if you read polling studies by Pew Research.
Those are the real facts, with some relevant sources noted..

You like asking questions that you think are "gotcha's", don't you?
Tell you what: what you are describing is an infinite series. Put the infinite series into a mathematical form, including a variable that tells you how much H2O increases by for a given temperature increase, and then how much that temperature increase will increase H2O, and see how it behaves?
You will probably find that not all infinite series lead to infinite increases. Some of them have finite limits and asymptotically approach a limiting value (as long as the appropriate mutiplliers fall within certain limits).

Regarding my comment @11,
There is growing understanding that 'being less of a consumer' can reduce impacts more than 'being more attentive to choosing lower impact options'.
'Reduced Consumption' can be really helpful. Energy use, and waste, is associated with almost any consumption. And there can be many other impacts from consumption, including non-climate change impacts of energy use, that are cumulatively more harmful as each person's consumption impacts add up. Tragically, every little bit of harm done adds up.

But people who improve their lives beyond a basic decent life should try to limit their 'excess optional' energy consumption.

Ah-hah. Jason really wants us to notice Klaus Schwab.
Here's some background on why (note the parroting*). It helps to explain Jason's "hiding in plain sight" angle.
Jason's mapping the original Great Reset crowd-sourced anxiety onto the IPCC. It doesn't make the jump very well.
We're seeing a kind of platypus being stitched together.
Still not hearing any complaints about what we know about why we should deal w/warming, how this controverts common sense. Instead, hints of descent into old fashioned, dull and boring denial are becoming more visible. All roads lead there when there's no useful argument against "seatbelts are good."
The discussion remains substantially stuck on "my ideology is offended."

"Or are you disputing that the IPCC is pushing the same agenda? Their mitigations report doesn't propose a focused list of completable projects to halt AGW and fix the climate, but just the opposite.

I completely disagee. It's like you must be looking at another page. The page you linked clearly shows a list of multiple climate change mitigation options and they would obviously resolve the problem, if properly applied. There may be other approaches but that is beside the point.
The page includes another column of information on how this relates to the UN sustainable development goals. So what? These are not a " great reset". I would suggest most countries and political parties would already subscribe to them in principle anyway and clearly many countries are already working towards these with varying levels of success. The following are the UN sustainable development goals:
GOAL 1: No Poverty
GOAL 2: Zero Hunger
GOAL 3: Good Health and Well-being
GOAL 4: Quality Education
GOAL 5: Gender Equality
GOAL 6: Clean Water and Sanitation
GOAL 7: Affordable and Clean Energy
GOAL 8: Decent Work and Economic Growth
GOAL 9: Industry, Innovation and Infrastructure
GOAL 10: Reduced Inequality
GOAL 11: Sustainable Cities and Communities
GOAL 12: Responsible Consumption and Production
GOAL 13: Climate Action
GOAL 14: Life Below Water
GOAL 15: Life on Land
GOAL 16: Peace and Justice Strong Institutions
GOAL 17: Partnerships to achieve the Goal -

In addition to my suggestion @3 that forests may be a good alternative to Titanics, in keeping with a 'living thing theme' maybe Blue Whales or Elephants could be used.
I am going through the presentation a second time to better understand it and provide additional comments.
On the Communicating Uncertainty image the Confidence image does not show that the confidence level is the combination of the amount/quality of evidence and the degree of agreement between the types of evidence. The presentation of the two as axis of a graph with confidence increasing diagonally up and to the right would be clearer.
Also on that panel the word "Asessing" under Confidence needs another 's'.

JasonChen:
You are either playing word games, or not understanding basic writing.
"Assessments" are not taking actions to address a problem. The IPCC reviews available scientific literature and summarizes it.
"Formulating strategies" is not taking actions to address a problem. It is giving advice. In the case of the IPCC, it is using the knowldege of the science it has assessed to indicate what the effect of various actions might be. Then policy makers can use that advice (or ignore it) when they choose to try to address climate change.
You know, don't you? That pesky "Summary for Policy Makers" that accompanies each report?
You are seeing monsters under every bed you see.

the IPCC's primary purpose is not addressing anthropogenic climate change.
Of course its purpose is to address climate change. Specifically:
- To make assessments of available scientific information on climate change.
- To make assessments of environmental and socio-economic impacts of climate change.
- To formulate response strategies to meet the challenge of climate change.
What's not that list is physics goals of fixing the climate or even predicting it well. 30 years later, the climate is neither fixed nor on a path to be fixed. Fixed hasn't even been defined. The IPCC hasn't identified anything close to a seat belt. The response strategies it has formulated have a conspicuous overlap with Klaus Schwab's agenda for maximal disruption. Large chunks of the world are rejecting them as economically and politically unpalatable. These are just facts.
Are they addressing climate change? Sure they are, in some sense.

I've now looked at all of it - much easier to read at this link
Re: 'The bath' graphic.
It might be more 'denier proof' if it had proprotionately thick or thin pipes to account for the fact that the inflow/outflow of the natural carbon cycle is much bigger than the human caused one.Re: 'The bad' graphic
I'm always unhappy about how activists say that Big Fossil Fuel is subsidised to the tune of, in your graphic $555 billion, but do not say that this is mostly standard tax breaks for investment employment etc that any business would get. There is an insinuation that these subsidies are 'special' ones just for Big Oil!Re: Two fruit bowls
I think an unfortunate omission in the 'higher hanging fruit' tree is advanced geothermal, which seems to be currently under most people's radar. Scroll down to, or search for, 'enhanced geothermal' or EGS.Without going into the various new developments, this holds out a very credible technology that would, besides being virtually emissions free, be widely available in almost every country on Earth 24/7/365, giving those countries significant energy independence. Planned plant have a very low 'footprint' area, unlike wind or solar... It has the further benefit that it would redeploy much of the work force and machinery of the oil and gas exploration industry to a good end, thus minimising the economic dispruption that would follow the shuttering of that industry.
RE: Demand side management
I love the 'buy less crap' line. Perhaps have a look at Buy me Once - a website that is trying to encourage the world to buy quality that lasts, rather than 'crap' that has to be purchased over and over againModerator Response:[BL} I have deleted what appears to have been a duplicate of this comment. If it contained new information, please outline it as a new comment, not as an attempt to revise an old one. (I am guessing it was an accidental resubmission.)

JasonChen,
I have been following this discussion.
I offer the following alternative perspective regarding the motives of parties acting related to the IPCC.
The first step is establishing the proper historical evidence based understanding of the formation of the IPCC. The history of the formation of the IPCC is no mystery. It was formally established by the UNEP and the WMO and was endorsed by the UN General Assembly in 1988. The motivation for forming the IPCC was the increased awareness and understanding of the harmful unsustainable developments that competition for status, including economic and political competition, created. And the first global conference to make the environment the major issue was the UN Conference on the Human Environment in Stockhom in 1972. That triggered many pursuits under the umbrella of pursuit of developing sustainable improvements for the future of humanity (in addition to earlier actions like the UN Universal Declaration of Human Rights)
That history is aligned with the research history that Doug Bostrom has focused on.
That independently verifiable evidence based understanding leads to the awareness that there is a nefarious group ... The misleading marketers trying to delay the limitation of harmful pursuits and the related required compensation to people who have been harmed by harmful unsustainable pursuits of benefit and status.

Doug Bostrom at 01:35 AM on 19 August 2022Skeptical Science New Research for Week #32 2022
Here's your claim, Jason:
"Are you doubting the Great Reset includes climate mitigation? Of course not, it explicitly calls for green infrastructure and ESG and all the usual globalist causes. It's not the Modest Reset or the Limited Reset, after all.
Or are you disputing that the IPCC is pushing the same agenda? Their mitigations report doesn't propose a focused list of completable projects to halt AGW and fix the climate, but just the opposite. It inventories every category of human and economic activity and invites governments to re-engineer all of them, with no expectation of a "done" state ever. It's a roadmap for everything but fixing the climate. Klaus Schwab's agenda, with a different sort order."
Shorter: the IPCC's primary purpose is not addressing anthropogenic climate change. In fact, the opposite. The IPCC's stated mission intentionally obscures its true objectives.
So, you appear to believe that we have a political/economic agenda "The Great Reset" sailing under false colors. "Globalists" (where is party headquarters?) are promoting their hidden agenda by expediently attaching themselves to climate research.
Supposing this conjecture were true and even if "globalists" had actually seized or conjured the IPCC for their hidden agenda, we're still left with the problem of anthropogenic climate change itself. Again, the worth of the message "you should wear seat belts" is independent of whether the advice comes from a communist or a capitalist, because the momentum of a human body moving at speed is independent of political ideology.
Others may perceive it differently, but what I'm hearing from you is some rather desperate straining to avoid fastening your seatbelt. Because the argument for fastening seatbelts is pretty much air tight, you must invent reasons for why doing so is to become putty in the hands of Big Safety. So, the invention to deal with this is that Big Safety is actually pursuing a hidden agenda to control your life and it becomes (apparently, because here we are) a matter of principle to oppose behaving sensiibly.
[And I'm left wondering: if we can't mutually discern the difference between mysticism and physics, between religious thought and scientific research, is there any point in proceeding with this discussion? When we begin hearing comparisons between the Catholic church and the scientific enterprise, that's suggestive of a profound gap in understanding, the need for intensive and broad remediation we won't be able accomplish here.]

Hello John Lang, Wow! These graphics and the graphics in the other work listed above will be incredibly valuable for me in my advocacy work. I am a fortunate Making-Sense-of-Climate-Denial alumni who went on to become a volunteer Climate Reality Project Leader.* I am now working with 1. the Climate Reality Project, 2. the Climate Reality Boston Metro chapter**, 3. HACE (Harvard Alumni for Climate and the Environment)***, and my town's Climate and Sustainability Action Plan Steering Committee. I will continue to investigate your work and share it wherever it seems applicable. I will also contact you to introduce myself and explain whenever I'd like to use your work for specific applications and how you'd like me to cite it. I am excited. I've only begun to think of how I can "speak" with your graphics. Your work is an incredible resource for me, and I argue for everyone who wants to speak with the general public about these issues as you and Katharine Hayhoe so eloquently point out is essential.

The presupposition being that anything you haven't run across in climate journals is "hidden" or "nowhere?" Yeah, I don't know about that.
Was the IPCC's founding a conspiracy? I don't know about that either, but it did have a purpose and a point of view which are revealed in these secret gauzy conjectural conspiracy documents.

Doug Bostrom at 16:02 PM on 18 August 2022Skeptical Science New Research for Week #32 2022
Thank you for answering my question, Jason.
Nowhere do the people and organizations you're traducing describe themselves, their origins, purpose, goals or activities as you claim.
Hence, you're describing a hidden agenda disguised as something else, a concerted organization operating covertly.
Put another way, you're describing a conspiracy, offering a conjecture of conspiracy.
Your portrayal doesn't rise to "conspiracy theory" or even hypothesis. It's too gauzy.
You can improve your conjecture by hard graft, the difficult work of tearing into literature and showing us where public policy that is emerging as a result of scientific research is being misguided. We make this easier; in a given month we offer hundreds of articles in an easy-to-find format. Have at it. Perhaps you'll find an important crack in the wall, but until you do no amount of hand-waving or evidence-free imputation will substitute.
Meanwhile— while we're waiting for that— public policy needs to be made and implemented, and commerce, markets and quite a bit of the rest of the human enterprise.need to adjust in respect of what physics tells us is happening and will happen, what we can see happening (see above, as usual). There's no option to wait while somebody indulges in and explores wild ideas. There's a clock running (see above, as usual).

Was it decided that we must rearrange parts of our physical economy? The passive voice and the cryptic "we" rob the question of any meaning. "We" don't decide anything. "We" may be perfectly happy to drop hammers, more concerned with our paychecks and careers and reputations and self-images than with most of the 70 billion toes out there.
What appears to have happened in the 1980s is that some faction at the WMO succeeded after a long lobbying effort in getting the UN to charter the IPCC with a half-scientific, half-political mission to assess the AGW science and make recommendations to governments on climate interventions to essentially slow the spread of global warming. Both the fact of AGW and the need for interventions were baked into the mission from the start.
30 years and countless billions later, the bench of researchers has swelled enormously. Careers have grown, new institutions born. The question of the future of the world's energy production has taken sharp political contours, because how could it not? The IPCC sits atop the great pyramid you describe. Everyone with an office in the pyramid agrees with the IPCC and stand united against the mobs of Deniers fuming in the sands outside.
Seems to me we cannot tell from this picture whether that WMO faction was right or wrong back in the 1980s. If they were right and the ranks of researchers since then have vindicated their predictions, we get the pyramid.
On the other hand if they were wrong, institutions take on their own momentum and quickly outpace any individual's ability to shift their course. Political institutions in particular are always concerned about political optics and pathologically unable to admit error. Over the years the power structure naturally evolves to filter for true believers and loyalists and to cast out boat-rockers. The institutions come to be filled with people who support the institutional narrative for the same reason 97% of popes support Catholicism. We would still be looking at a pyramid.

"The media distorts and misuses..."
Whoops. We're not talkiing about "the media," popular media. There are fundamental, profound differences between popular media and academic research journals and articles published therein. If this isn't clear and plainly obvious, it's a failure of communications on our part.
Pictures would help, but in the meantime, take a look at a sampling of articles above. Notice that each article sits on a "pyramid" (it would look like a pyramid if all the work was printed and stacked) of other articles, with new claims in aritcles sitting at the tip of the structure and supported by what's below. Notice that as one descends "layers" of papers in this pyramid, the same convention of support from below applies, with the network of support rapidly expanding. There is a huge degree of connection here, and agreement. Understanding this is key to understanding how scientific literature is a most implausible collaborator in any policy enterprise operating evidence-free.
Significantly, the entire structure is available for examination and 20:20 hindsight.
So that we're in understanding, Jason, is it your proposition that first it was decided we must rearrange parts of our physical economy, then that the entire scientific community was enrolled in the plan?
And if not, and if what we know says "we need to make some changes" and this is a matter of broad agreement (we shouldn't drop hammers on our toes), what is the problem you see? I ask because most people wouldn't see a problem with this.

JasonChen at 12:01 PM on 18 August 2022Skeptical Science New Research for Week #32 2022
I'm still not clear whom you're debunking. The initial reference was "a globalist elite promoting CC as part of a Great Reset." It seems pretty easy to identify factions meeting all four criteria. They need not be secret, nor coordinated, and like all of us they will have a gamut of motivations from the practical to the ideological. There need not be any org chart, no overarching organization, no mastermind coordinating the planet to make the Reset Great again.
Specifically, what articles are you expecting to see that you're not? The media distorts and misuses climate research constantly and everywhere. "Sunny day could be linked to climate change." "Experts shocked by latest findings." "It's even worse than we thought!" I wouldn't expect academic journals to publish letters from aggrieved researchers done wrong by the Washington Post. Nor exposés of the narrative advanced in the IPCC reports.
-
Doug Bostrom at 10:25 AM on 18 August 2022Skeptical Science New Research for Week #32 2022
The "Great Reset" purports that pragmatic reasons are secondary to ideological ambitions, Jason.
This is a fallacy based on inverted predicates.
Physics created a market for safety belts, mitigation against catastrophic injury as a side-effect of a human activity and its unintended outcomes.
Given that we're speaking of human nature including greed and self-interest, it was pretty much inevitable that improvement of vehicle safety would require regulatory oversight, adults in the room (us, acting together through public policy) to heed. Seatbelts required intervention against self-interest, yes— secondary to newly understood information.
But improvement started with physics, passed on to address human nature, reaching an acceptable outcome.
Political philosophy doesn't set physical constants, material properties. In the mid '70s the USSR mandated safety belt use, far earlier than any US state. Does this belated obedience to physics on our part mean we became communists? No— it means that physics doesn't depend on political philosophy. Here in the US as a matter of political belief and practice we're sometimes seemingly confused between freedom to think, speak and worship vs. freedom to die foolishly and needlessly after striking a hard object at speed. But kinetics remains aloof from our thoughts, visible as a serene constant when we don't think carefully.
Science first, mitigation second. Evidence then reply to evidence. It's not complicated. Here physics is telling us about forces much larger than a body passing through a windshield. But it's still physics first, policy reply second.
There is indeed a much larger market for ideas in for stepping over and past anthropogenic global warming. Money will move from one industry to another. That after all is why we're having this 30-years-stale conversation. We're part of the "addressing human nature phase," our waste of time and energy prolonged because stakes are high.
Meanwhile, we can (as indicated above) be pretty sure that if hundreds of thousands of researchers practicing within their own domains are seeing their work distorted or abused in furtherance of a hidden agenda by other investigators, with (let's say) 300,000 researchers victimized and a 1% objection rate we'd be hearing from about 3,000 of them— published in the collection of journals we see above, with great delight and zero chance of going unnoticed and unremarked.
These researchers would be showing exactly how their work was being misused, with arguments built on supporting citations. That isn't going to happen, obviously; nobody's going to or can argue against 9.8m/s/s. While this situation is a bit more complicated than an apple falling from a tree, the problem of warming is only the revealed product of a large unpacking of some basic principles.
As well, it's worth noting (as we can see from the densely dendritic connections between articles and their authors) that contradicting publications by offended workers would in turn would trigger an explosion of replies in various forms, a "prompt criticality" effect, producing the academic equivalent of a saloon brawl with geometrically increasing numbers of pugilists.
Where are these articles? Where's the sound and fury? It's nowhere. We see a few papers attempting to disprove AGW from first principles and failing badly when tested, hence fizzling as a source of research energy. Beyond that, crickets.
Meanwhile, I think in fairness we need to see a coherent org chart of The Great Reset. What's the leadership? How do instructions flow? How is agreement on the agenda decided and agreed? Who pays the bills, and where are the books? China's government is at loggerheads with the US government on many matters, but they privately agree to execute a hidden agenda with nary a slip? What does this look lik as a matter of record? Etc. Short of having all that to see, the great reset sounds like great conjecture unsupported by facts. Coupled with the lack of objections by persons who actually do know better and could explain how, the whole concept seems greatly unlikely.
There's no explanatory or predictive power in "they're perfectly all in it together," because that assumes invisibility, hence unfalsifiability, leaving us with nothing to work with. On the other hand, we have a mountain of well founded consilience.
There's no exciting mystery here, no shadowy forces, nothing really more dramatic than "you shouldn't drop that hammer on your foot," widely agreed. Physicists say the hammer will develop kinetic energy, doctors say this will cause injury at a certain statistical rate, bootmakers sell steel-toed boots to address accidents, and maybe we'll figure out a safer tool than the hammer we're used to holding. Some of us are such that we'll need some help understanding why and how this is all commmon sense— including those who sell hammers for a living. Change forces at play, scale, see AGW, fix.That's all we're talking about. Let's all calm down and not get in a lather about conspiracies.

Of course so many people could never keep the Great Reset a secret, that's how we know about it. That and all the publicizing from the WEF. The lack of secrecy doesn't prove it's imaginary, it shows it's real. So what are you debunking?
Are you doubting the Great Reset includes climate mitigation? Of course not, it explicitly calls for green infrastructure and ESG and all the usual globalist causes. It's not the Modest Reset or the Limited Reset, after all.
Or are you disputing that the IPCC is pushing the same agenda? Their mitigations report doesn't propose a focused list of completable projects to halt AGW and fix the climate, but just the opposite. It inventories every category of human and economic activity and invites governments to re-engineer all of them, with no expectation of a "done" state ever. It's a roadmap for everything but fixing the climate. Klaus Schwab's agenda, with a different sort order.

Like Nick I have not yet finished reading the entire presentation. What I have seen so far does look like it should help someone who is interested in being more aware and better understanding things.
I wonder if it would be helpful to use the tonnes of carbon in a square kilometre of mature healthy forest (with the value per square mile in brackets). The complication is clarifying that one number would be for the average amount of carbon contained in the forest and another number would be the annual additional carbon capture and sequestration. A further complication to explain would be the range of values by forest type. But all of that additional explanation in a footnote could be helpful.
I suggest the square kilometer (mile) rather than hectare (acre). I am not convinced that many people in the general population have as good an idea about the size of an acre or hectare.

I haven't been through the whole post yet (I'm otherwise busy) but this section stood out
"After much internal angst and external debate, I chose to illustrate the weight of human-caused CO2 emissions using Titanics rather than, for example, London double-decker buses. Both are too anglicized, so I’m all ears for a more universally relevant suggestion. The Great Pyramid of Giza? "
How about using some US centred icons, as that's where a lot of opposition comes from? Possible icons: Mount Rushmore, Mount st Helens, Statue of Liberty, Empire State building, Golden gate Bridge, Hoover dam etc -
prove we are smart at 12:46 PM on 17 August 2022Geothermal heating and cooling: Renewable energy’s hidden gem
"Doing the right thing in a corporate setting", very unusual words coming from the corporate states of America!
Another positive, fossil fuel reducing fixit. Upon reading this last link given on this repost architecture2030.org/why-the-building-sector/ , that was an eye-openner! The amount of urban growth the globe will need by 2060 is "the equivalent of adding an entire New York City to the world, every month, for 40 years."
That certainly wont help our over-shoot problem and keep quiet about endless growth on a finite planet. Look, these renewable energy solutions are needed and good news, geo-thermal with heat-pumps are great and also proven to be a good solution to fossil fuel types but how long till these innovations are common place?-we are running out of time.
"In 2022, we predict this seasonal cycle to peak at a monthly mean value of 421.5 ± 0.5 ppm in May (Figure 1, Table 2). This will be the first time in the Keeling Curve record that monthly CO2 levels have exceeded 420 ppm, and from comparison with reconstructions of past CO2 levels from isotopes of carbon and boron in marine sediments, this will be the highest atmospheric CO2 concentration for over 2 million years." Taken from www.metoffice.gov.uk/research/climate/seasonal-to-decadal/long-range/forecasts/co2-forecast
I appreciate these engineers helping to prove a transition away from fossil fuels in a real world improvement for our biosphere. But with some tipping points activated with no turning back, and probably worse to come-it's all too little,too late..
