Apart from ATTP's posts on his own website (with relatively brief comments) . . . there is a great deal more in the above-mentioned PubPeer thread (from September 2019) ~ for those who have time to go through it.
So far, I am only about one-third of the way at the PubPeer one. Yet worth quoting Ken Rice [=ATTP] at #59 of PubPeer :-
"Pat, Noone disagrees that the error propagation formula you're using is indeed a valid propagation formula. The issue is that you shouldn't just apply it blindly whenever you have some uncertainty that you think needs to be propagated. As has been pointed out to you many, many, many, many times before, the uncertainty in the cloud forcing is a base state error, which should not be propagated in the way you've done so. This uncertainty means that there will be an uncertainty in the state to which the system will tend; it doesn't mean that the range of possible states diverges with time."
In all of Pat Frank's many, many, many truculent diatribes on PubPeer, he continues to show a blindness to the unphysical aspect of his assertions.

Bob Loblaw at 22:48 PM on 26 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Although DiagramMonkey may think that I am a braver person than he is, I would reserve "braver" for people that have a head vice strong enough to spend any amount of time reading and rationally commenting on anything posted at WUWT. I don't think I would survive watching a 1h26m video involving Pat Frank.
I didn't start the hagfish analogy. If you read the DiagramMonkey link I gave earlier, note that a lot of his hagfish analogy is indeed discussing defence mechanisms. Using the defence mechanism to defend one's self from reality is still a defence mechanism.
The "per year" part of Pat Frank's insanity has a strong presence in the PubPeer thread bigoilbob linked to in comment 27 (and elsewhere in other related discussions). I learned that watts are Joules/second - so already a measure per unit time - something like 40-50 years ago. Maybe some day Pat Frank will figure this out, but I am not hopeful.

bdgwx at 10:43 AM on 26 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Electic, I appreciate the kind words. I think the strangest part of my conversation with Pat Frank is when he quotes Lauer & Hamilton saying 4 W m-2 and then gaslights me because I didn't arbitary change the units to W m-2 year-1 like he did. The sad part is that he did this in a "peer reviwed" publication. Oh wait...Frontiers in Earth Science is a predatory journal.

Eclectic at 05:09 AM on 26 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Bdgwx @36 , you have made numerous comments at WUWT blogsite, where the YouTube Pat Frank / Tom Nelson interview was "featured" as a post on 25th August 2023.
Video length is one hour and 26 minutes long. ( I have not viewed it myself, for I hold that anything produced by Tom Nelson is highly likely to be a waste of time . . . but I am prepared to temporarily suspend that opinion, if an SkS reader can refer me to a worthwhile Nelson production.)
The WUWT comments column has the advantage that it can be skimmed through. The first 15 or so comments are the usual rubbish, but then things gradually pick up steam. Particularly, see comments by AlanJ and bdgwx , which are drawing heat from the usual suspects (including Pat Frank).
Warning : a somewhat masochistic perseverance is required by the reader. But for those who occasionally enjoy the Three-Ring Circus of absurdity found at WUWT blog, it might have its entertaining aspects. Myself, I alternated between guffaws and head-explodings. Bob Loblaw's reference to hagfish (up-thread) certainly comes to mind. The amount of hagfish "sticky gloop" exuded by Frank & his supporters is quite spectacular.
[ The hagfish analogy breaks down ~ because the hagfish uses sticky-gloop to defend itself . . . while the denialist uses sticky-gloop to confuse himself especially. ]

bdgwx at 03:46 AM on 26 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
I'm sure this has already been discussed. But regarding Frank 2019 concerning CMIP model uncertainty the most egregious mistake Frank makes is interpretting the 4 W/m2 calibration error of the longwave cloud flux from Lauer & Hamilton 2013 as 4 W/m2.year. He sneakily changed the units from W/m2 to W/m2.year.
And on top of that he arbitrarily picked a year as a model timestep for the propagation of uncertainty even though many climate models operate on hourly timesteps. It's easy to see the absurdity of his method when you consider how quickly his uncertainty blows up if he had arbitrarily picked an hour as the timestep.
Using equstions 5.2 and 6 and assuming F0 = 34 W/m2 and 100 year prediction period we get ±16 K for yearly model timesteps and ±1526 K for hourly model timesteps. Not only is it absurd, but it's not even physically possible.

Bob Loblaw at 08:10 AM on 25 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
In the "small world" category, a comment over at AndThenTheresPhysics has pointed people to another DiagramMonkey post that covers a semi-related topic: a really bad paper by one Stuart Harris, a retired University of Calgary geography professor. The paper argues several climate myths.
I have had a ROFLMAO moment reading that DiagramMonkey post. Why? Well in the second-last paragraph of my review of Pat Frank's paper (above), I said:
I am reminded of a time many years ago when I read a book review of a particularly bad “science” book: the reviewer said “either this book did not receive adequate technical review, or the author chose to ignore it”.
That was a book (on permafrost) that was written by none other than Stuart Harris. I remember reviewing a paper of his (for a permafrost conference) 30 years ago. His work was terrible then. It obviously has not improved with age.

Markp @2
The IPCC do indeed have this scientific reticence. Its like a sort of conservatism. But its not just the IPCC. Science has operated that way for centuries and for good reasons.Some initial scientific findings prove to be false so the conservatism is a form of quality control. If the scientific community was too quick to endorse every new scientific finding then all its credibility would have been gone long ago, and everyone would have stopped listening long ago.
We have problems with a public backlash even now, when a theory proves to be incorrect (fortunately its very uncommon) so imagine if the scientific community was less conservative that it is. So although I'm not a conservative sort of person as such, and dislike playing down of risk assessments, I respect that its probably better that organisations like the IPCC are a little bit conservative.
That said how conservative are they? If you read their reports there are charts showing warming could reach 5 degrees this century and 10 degrees by 2300. And charts now upgraded to show that 2 M SLR is possible this century as low probability but high impact event.This does not look excessively reticent or conservative.
And do you think that adding a degree or two to those scary looking numbers would change the public perception much, and lead to stronger mitigation? I'm not seeing it. If the public cant work out that 5 degrees of warming this century under BAU is serious I doubt that saying its 7 degrees would make much difference. All we can do is repeat the implications for the planet of the official projections, explain them as well as we can, and point out the serious climate changes and the increased preponderance of heatwaves and flooding we are already seeing, and as loudly as we can.
Fossil fuel exporting countries do indeed have a malign influence on the Summary for Policy makers. Can't find the reference now but apparently some terms on levels of risk have been weakened and references to fossil fuels minimised. This is a very real concern and does mean we need to understand things are worse than the SFPM suggests. If you read beyond the SFPM and to the fine details, and the actual charts, things are not watered down in the same way. The trouble is who reads that?
Regarding your complaint that billionaires profit out of climate solutions and might have other ulterior motives, and countering this with the suggested alternative of placing solar reflectors on the ground. Its a possible climate solution, but billionaires will still make money out of this one way or the other. Its hard to escape the private sector making money out of climate solutions, given the structure of our economy. I don't care as long as the job gets done, and they are not breaking laws or profiterring as such. It would be good if they reduced their personal climate footprint, and showed some meaningful climate leadership and helped those less fortunate than themselves.

Low sulfur diesel fuel has been out for how long? 25 yr? If this is reducing cloud formation, then diesel engine particulates may have been helping too by shielding the sun, and possibly creating clouds. Now particulates are so low you can't see any smoke. They even have particulate traps. China and India better keep burning coal since the smoke probably reflects the sun. Seems it is more complex than CO2 and could explain some anomalies.

One Planet Only Forever at 02:54 AM on 25 August 2023ClimateAdam: The Vlog Brothers on geoengineering
Markp,
I agree that the IPCC presentation of understanding regarding 'the problem and the solutions' has been harmfully compromised by 'interests that conflict with the development of sustainable improvements for humanity, regionally or globally'.
However, IPCC is not responsible for 'promoting increased awareness and improved understanding' regarding the understanding that is compiled by the IPCC. The leaders (in political and business, globally and regionally) need to be 'held responsible' for the promotion of increased awareness and improved understanding.
The IPCC report presentation must be consistent with the available evidence. That requirement has resulted in the progressive strengthening of IPCC statements contrary to the desires and interests of the undeserving portion of leadership competitors around the planet. And the latest IPCC statement concludes that, based on the evidence, the lack of leadership action through the past 30 years has created a situation where it is almost certain that 'reasonably limiting the harm done to the future of humanity' will 'now' require dramatic reductions and limits of harmful consumption, especially energy over-consumption (desired but 'unnecessary' consumption), as well as removal of CO2 from the atmosphere - even if those actions reduce the status of people who unjustifiably developed perceptions of higher status (permitting those developing to be like the higher status people to become more harmful while requiring the higher status people to set less harmful examples for everyone else to aspire to).
The awareness and understanding that now undeniably needs to be promoted is that many of the current leaders (winners) are undeserving of their status. They have proven to be unworthy of their wealth and influence through their efforts to weaken the presentation of understanding by the IPCC which made it easier for them to actively promote 'doubt regarding the fundamental understanding of the required corrections and requirement to make amends for harm done' that is presented by the IPCC.
The current situation can be understood to be the result of a history of harmful irresponsible actions by undeserving wealthy powerful people. Arguing for 'significant climate geoengineering actions', rather than promoting the fundamental 'need to end harmful human geoengineering impacts that incorrectly developed popularity and profitability' and 'reducing the harmfully over-developed GHG levels', will not address the real problem ... it will not result in sustainable solutions.

Rob Honeycutt at 00:00 AM on 25 August 2023ClimateAdam: The Vlog Brothers on geoengineering
Markp... "Adam and Miriam accept the logic that the only necessary thing to do in order to reverse GW is to reverse GHGs, in other words, get rid of them. That's a little bit like having your doctor tell you that in order to cure your tobacco-caused cancer, you just need to stop smoking."
This is a grossly innaccurate comparison. GW isn't a cancer, being that cancer is a growth. Tobacco smoking damages cells which then become cancerous. You can't reverse that effect.
Global warming, on the contrary, is not a growth. It is an effect due to the radiative properties of GHG's in the atmopshere. If you stop emitting CO2 you stop the warming, and it's now understood, that cessation of warming would be near immediate when we stop the increase of atmospheric concentrations.
-
Markp at 22:49 PM on 24 August 2023ClimateAdam: The Vlog Brothers on geoengineering
This is a reasonably well-done video by Adam, but there are some points that need to be made.
As many people have learned, the IPCC has done a pretty lousy job of informing the public, and the scientific views it presents have been warped both by the scientists themselves (the dreaded "scientific reticence" effect) as well as the politicians from 195 member countries that have veto power on much of the content released to the public which can be generally characterized as very, very conservative. In other words, it's way worse than they tell us, and their "solutions" not nearly as effective as they tell us. Adam and his friend Miriam are both, from what I can tell, very much cheerleaders for the IPCC. Not surprising: they are fresh out of university and so in that sense have not spent much (any?) time in the real world of working scientists, so their current YouTube careers aside, they may not want to annoy the IPCC-dominated narrative on all things climate.
Two big issues: 1) we need geoengineering more than they tell us, and 2) there is more to geoengineering than SAI.
1) Like so many climate scientists under the spell of the IPCC, (for many reasons which take too long to unpack here) Adam and Miriam accept the logic that the only necessary thing to do in order to reverse GW is to reverse GHGs, in other words, get rid of them. That's a little bit like having your doctor tell you that in order to cure your tobacco-caused cancer, you just need to stop smoking. Fighting the cause isn't always guaranteed to bring about a result in a timely manner. Reducing GHGs, yes, but who is doing that? Miriam said something like international agreements like Paris have "already reduced warming by 1C" and I say huh? All the talk of international agreements sounds good but isn't our reality, as anyone looking at our world's biggest problems today knows in an instant. Our "efforts" to reduce emissions are nowhere. It's not happening. Targets and discussions aren't enough. The point that people behind geoengineering make is: emissions reduction is not and WILL NOT happen fast enough to stop our ecosystem from collapsing. Additionally, carbon removal methods, whether nature-based or mechanical, have huge scaling problems. Yes, nature has dealt with CO2 in the past, but not like what we have now. They are very slow, are not always even feasible (tree-planting a perfect example, look at the studies) and have other issues such as water constraints making them impossible at scale. And mechanical CO2 removal is even worse. When it works, it's fast, but unscalable, with DAC being the most obvious case. So after the IPCC cheerleading stops, we have to face the music. We don't have time to rely only on the method of "turn off the tap and clean up the mess."
2) Geoengineering (you heard Adam slip in "SRM" as well, Solar Radiation Management, a type of geoengineering) is almost always equated with just ONE currently discussed method, which is Stratospheric Aerosol Injection, or SAI. That's because it's got a lot of billionaire-potential!
SAI is NOT more than a theory at this point, however. But you won't find that mentioned by many of its proponents. It is not the only way to go, is not loved by many (unbiased) climate scientists, has oodles of scientific problems to overcome if it would even work, and so is NOT the end of the geoengineering or SRM story. So Nigelj's characterization above, which makes it seem that SAI is ready-for-take-off, is wrong.
I will admit that, like the VAST majority of actual movement on climate we have seen, geoengineering efforts have a lot in common with disaster capitalism, and so should be checked out very thoroughly. Making money off of GW is the most effective thing we humans have done to date, which is a crime against humanity. Period. Governments now throwing large sums of money out for grants only on very narrowly-defined work chokes real progress. What we forget is that scientists have to get paid. Who pays them? Why? Most scientific research is arguably being funded by those who are expecting a product to patent and sell if things go well. Scientists are NOT always out there trying to find the fastest most practical fix here. The more tech that goes into it, the better. The more career-building we can get out of it, the better. That's why we see people talking about, of all things, space mirrors, as if simply putting them on the ground here to do what clouds and snow do is out of the question. There are people promoting that very idea and it has vastly more promise than any other geoengineering solution but is largely ignored (but that's changing) because it doesn't create billionaires and cannot be weaponized.
Like many things, this discussion has so much more to it than meets the eye. We need to think, REALLY think, and be realistic, and stop listening so much to government institutions (or their cheerleaders) that have almost never served anyone other than the powerful very well.

nigelj at 06:18 AM on 24 August 2023ClimateAdam: The Vlog Brothers on geoengineering
Lets imagine a scenario where the world fails to reduce emissions enough to adequately fix the climate problem, leaving tropical countries sweltering in the heat with unendurable heatwaves.
The world debates geoengineering, but countries like America are (rightly) concerned about side effects of geoengineering and prefer sucking CO2 out of the atmpsphere - but the costs on the global economy are considerable. Nobody can make a decision.
Tropical zone countries become desperate and form a group and they start spaying aerosols over huge areas of the planet, risking negative side effects for everyone. All it takes are a fleet of aircraft. How would you stop them? Shoot aircraft down? Trade embargos? Beg them to stop? Whatever you do to try and stop them, it looks like a huge problem to me.

Bob Loblaw at 23:29 PM on 23 August 2023At a glance - How substances in trace amounts can cause large effects
ubrew12:
Your analogy is a bit hard to follow. I presume that the point you are trying to make is:
- The best players in the world will not be very effective in stopping you from reaching the goal when their shoes are tied together. As a result, your chances of scoring are high. This is analogous to IR radiation easily passing through gases that do not absorb well.
- Even a mediocre player that is free to run around and get in your way has a good chance of stopping you, even if he only represents 2% of the players on the field (most of whom are limited by having their shoes tied together). This is analogous to CO2 blocking IR radiation, even though its concentration is small compared to the gases that are not blocking IR radiation.
- So, your chances of scoring are largely the result of the one player free to run around and defend against you, not the 50 players with their shoes tied. Expressing the concentration of untied players relative to the tied players is misleading.
To extend the analogy, if they took away 25 of the players with their shoes tied, the local high school player would now be 4% of the total opposition. But that does not mean that he would be twice as effective at stopping you. He's still only one player.
For a further look at how concentrations of CO2 in ppm can be misleading, it is worth reading this blog post (to beat my own drum):
-
Bob Loblaw at 23:11 PM on 23 August 2023Climate Confusion
Markp @ 19:
In your first paragraph, you appear to be confusing two different scenarios:
- net zero implies that anthropogenic net additions to atmospheric CO2 are zero (which means emissions are zero, or we have found ways to remove CO2 as well as add it).
- Stabilize CO2 means that atmospheric concentrations are not changing - which can happen when anthropogenic net contributions are still positive, but are balanced because natural removals exceed natural additions by the same amount.
In the first case (net zero), natural removals (which currently exceed natural additions) will cause a reduction in atmospheric CO2 over the next decades, and we expect to see temperatures stabilize. The decreasing CO2 will not lead immediately to cooling, because the current CO2 levels still have "warming in the pipeline" that will offset the immediate direct cooling effect of less CO2.
In the second case (CO2 stable), there is still "warming in the pipeline", so we expect to see temperatures continue to rise for a while.
Once you understand this difference, I expect that much of your confusion will dissipate.
-
Eclectic at 22:20 PM on 23 August 2023Climate Confusion
Markp @19 , your final paragraph is, in itself, showing lack of clarity.
Cynical people (like you and I ) as well as non-cynical people, should surely wish to take practical action to achieve nett-zero carbon emissions in a reasonably quick manner ~ even though those scientists (with various levels of "ept" ) fail to give perfect precision of projection of the probable prospective developments [futurists refer to this as the problem of pppppd scenario ].
More seriously, Markp . . . what alternatives are you suggesting?
-
Markp at 20:25 PM on 23 August 2023Climate Confusion
I'm still not sold on the idea that zero or net-zero emissions implies no future warming, as Evan says "A world where the best we do is to stabilize CO2 has, for all intents and purposes, "warming in the pipeline", something that does not occur if and when we reach net-zero emissions."
First of all, it is not ultimately GHGs that determine warming, it is the EEI that does that. In other words, as I understand it, if the EEI is positive, but GHG emissions are zero, Earth still warms.
I also find it problematic that the idea of "zero emissions" or "net-zero" seems to imply to most people that all we are talking about are human emissions, when the possibility of an end to human emissions could exist while (significant) non-human emissions (for example permafrost melt) could still create warming, so that we are actually not at zero or even net-zero emissions regardless of source.
I have long searched for a really solid scientific explanation of the concept of baked-in or committed warming that carefully tries to help people understand why some scientists say it exists and some say it doesn't. But the Zeke piece (and I don't trust for-profit scientists on this) is not convincing and neither is the Scientific American piece.
Neither is the MacDougall 2022 ZECMIP study paper which clearly states "The most policy relevant question related to this research is: will global temperatures continue to increase following complete cessation of greenhouse gas and aerosol emissions? The present iteration of the study aims to answer part of this question by examining the temperature response in idealized CO2-only climate model experiments. To answer the question in full, the behaviour of non-CO2 greenhouse gases, aerosols, and land-use-change must be accounted for in a consistent way," which is another way of admitting that ZECMIP at this point is still "garbage in, garbage out."
In fact, the pieces I have found seem to rely purely on models which are always incomplete, as is ZECMIP.
And neither is this piece by Evan able to clarify this for me. Evan simply says it does not happen, as if that's been settled. He does not mention the warming, for example, that would come from the (potentially sudden? would it even matter?) end of reflective fossil fuel aerosols.
The amazing lack of clarity on this subject, which is absolutely crucial to the discussion of any need to lower emissions, is astonishing, and leads cynical people like me to assume that it is a result of the IPCC-induced obfuscation and the complete ineptitude on the part of scientists to recognize that this issue is important and to do something about providing clarity.

Say I'm on the soccer field. The ball is infrared radiation. Against me are 50 of the best players in the World. Can I make a goal? Did I mention their shoes are tied together?
Now, put one more opposing player, from the local high school, only his shoes aren't tied together. Can I make a goal? Suddenly, it's not as certain. The opposing team has only grown by 2%, but my chances of making a goal have dropped around 50%.

Thanks OPOF!
Yes, it's a bit frustrating and indeed ironic that we don't have the full Samoilenko & Cook paper on tap, only the submitted manuscript.
An object lesson of sorts on the weird intersection between for-profit publishers and science. Climate Policy is published by Taylor & Francis, which in turn is owned by Informa, which as a publicly traded company is intended for the purpose of rent-seeking for the benefit of investors as opposed to advancing the state of human knowledge. The rent-seeking objective is quite successful; by jealously guarding and obfuscating scientific information, Informa yielded three quarters of a billon dollars of profit last year. We could wish that selling sewage was a more profitable avenue thus luring the cloud of investor flies looking for free lunch in that direction. But as it stands now, hiding information from the public is the best deal on offer.
It may be that the authors still have managed to cling to the right to individually share what they've learned and won't be sued if they do so. Try emailing john[at]skepticalscience.com if you're keen to see figures.

The developed understanding can be understood to apply to misinformation attacks on other efforts to increase awareness and understanding, like the Sustainable Development Goals, that result in requiring:
- changes of direction of development (Systemic Change)
- correction of development that has already occured (Changing the Status Quo)
- making amends for harm done by past actions (Systemic Change that Changes the Status Quo)

Climate Policy. doi.org/10.1080/14693062.2023.2245792" paper highlighted on "Skeptical Science New Research for Week #33 2023")
The short statement by J4sonian can be considered to be a dog-whistle appeal to people who have developed a motivation to disrespect and be dismissive of 'Al Gore'. The 'delivery guy' term can easily be interpreted that way.
The nasty thing about dog-whistle misleading messages is the way that they can be claimed to 'not be the misinformation appeal to people who are inclined to be unjustifiably impressed that it is intended to be'. 'Delivery Guy' could be claimed to have been a friendly colloquial way of describing a diligent pursuer and presenter of increased awareness and better understanding
A history of clearly attempting to help increase awareness and improve understanding regarding climate science by J4sonian could convince me that their comment was not meant to 'disrespect Al Gore as a means of being dismissive of the information he raised awareness of'. And a part of that would include J4sonian admitting that when Al Gore produced An Inconvenient Truth he had a significantly better awareness and understanding of climate science that many 'geologists at that time' and many 'geologists claiming to be well informed regarding climate science today'.
In summary, a reasonable sounding clarification from J4sonian could be a more subtle dog-whistle appeal to people who are motivated to dislike increased awareness and improved understanding regarding climate science and the related required corrections of 'harmful over-consuming developed ways of living' and 'making amends for the harm done'.

Bob Loblaw at 03:36 AM on 20 August 2023A Frank Discussion About the Propagation of Measurement Uncertainty
Thanks, bigoilbob.
That PubPeer thread is difficult to read. The obstinance by Pat Frank is painful to watch.
One classic comment from Pat Frank:
Everyone understands the 1/sqrt(N) rule for random error, Joshua.
Except, apparently, Pat Frank, who in the paper reviewed above seems to have messed up square rooting the N when propagating the standard deviation into the error of the mean. Unless he actually thinks that non-randomness in errors can be handled by simply dropping the sqrt.
Pat Frank is also quite insistent in that comment thread that summing up a year's worth of a measurement (e.g. temperature) and dividing by the number of measurements to get an annual average gives a value of [original units] per year.
Gavin Cawley sums it up in this comment:
I had a look at your responses to reviewers on the previous submissions, which seem also to contain this very poor attitude to criticism. It tells me there is no point in me explaining to you what is wrong with your paper, because you have made it very clear that you are not prepared to listen to anybody that disagrees with you.

"Do you have any link to specific statements from Carl Wunsch? Curiosity arises."
Specifically, this is what I found. Old news, but not to me. I hope that I did not mischaracterize Dr. Wunsch earlier, and my apologies to both him and readers if aI did so.
"#5 Carl Wunsch
I am listed as a reviewer, but that should not be interpreted as an endorsement of the paper. In the version that I finally agreed to, there were some interesting and useful descriptions of the behavior of climate models run in predictive mode. That is not a justification for concluding the climate signals cannot be detected! In particular, I do not recall the sentence "The unavoidable conclusion is that a temperature signal from anthropogenic CO2 emissions (if any) cannot have been, nor presently can be, evidenced in climate observables." which I regard as a complete non sequitur and with which I disagree totally.The published version had numerous additions that did not appear in the last version I saw.
I thought the version I did see raised important questions, rarely discussed, of the presence of both systematic and random walk errors in models run in predictive mode and that some discussion of these issues might be worthwhile."

OPOF #8 - that was my impression and it was why I responded sharply: however, if I have miscalled comment #5 then I apologise for that.

Bob Loblaw @7,
I agree more with John Mason's approach. But I would go further and ask J4zonian to explain how they are more qualified today regarding the awareness and understanding of climate science than Al Gore was when he developed An Inconvenient Truth. Al Gore was a very aware individual at the time with a significant understanding of the science. And he knows far more today.
I am more inclined towards the perception that J4zonian is unjustifiably disrespecting Al Gore. And I sense that the disrespect is due to a dislike for the understanding that Al Gore shared.
The understanding that Al Gore 'shared' increased the common sense awareness and understanding of the issue, especially the need for harmful inconsiderate over-consuming Americans, and others like them, to change how they live to be less harmful and more helpful to others (contrary to the untruthful declarations by both 'Bush' Presidents of the Neoliberal mantra that harmfully over-developed Americans are 'the winners' and did not have to change how they lived or make amends for the harm done by 'their success' - Many Republicans and Some Democrats still chant versions of that untruth).

John @ 6:
I don't think J4zonian is saying "don't believe Al Gore because he's just a delivery man". I think J4zonian is saying that Al Gore is a messenger of the science, so even if he gets a little bit wrong here and there, the original diagnosis and medicine is largely correct.
I think.

"because a single doctor misdiagnoses a condition, medicine should be abolished in its entirety."
It's Al Gore. It's more like a delivery guy misdiagnosed a condition.

Don Williams :
Since you seem reluctant to engage in rational discussion ~ may I suggest you instead join the comments columns of WattsUpWithThat blog?
There at WUWT one will find scores of commenters brimming with anger at the world ( and at themselves, inwardly ). Plenty of disingenuousness and deliberate ignorance there . . . enough to satisfy any like-minded spirit. You might well be pleased!
At WUWT blog, the ice age has never ended.

MA Rodger @ 138:
Yes, this discussion is wandering off the blog post's topic. There is no way to determine Don Williamson's motives unless he explains them, but it appears that he is trying to do two things:
- Take Oreskes' paper out of context to make it look like the 1970s "cooling" story was an indicator of a huge shift in climate science [it wasn't] - I presume to discredit climatology as a science [he hasn't].
- Bootstrap the idea that "they don't know what they are talking about - they'll just make stuff up" by using the hiatus as an indicator that warming isn't linked to CO2 increases [he's wrong] and we might flip back into decades or centuries of cooling even if we burn every last bit of fossil fuels [we won't].
I have an off-topic challenge to Don that he has not yet responded to (review one example of the many "hiatus" papers he insinuates support him). I need to let him respond, if he is willing or able.
If the off-topic sound bites continue without responding to that challenge, I will probably need to bow out of the conversation and take on a moderator role.

I agree that science will simply ignore the paper. But the target is probably not the science community: it's the "we'll believe ABC [Anything But Carbon]" community, which unfortunately includes large blocks of politicians with significant power. All they need is a thick paper that has enough weight (physical mass, not significance) to survive being tossed down the stairwell, with a sound bite that says "mainstream science has it all wrong". It doesn't matter that the paper isn't worth putting at the bottom of a budgie cage.
