BillJoe @27 , it is 6 years too late to expunge the "gotcha". And it wouldn't make any difference anyway — the denialists will always continue to recycle anything at all which they think (in their febrile minds) scores a "gotcha" point. All you can do, yourself, is to develop some good ripostes — for the benefit of the audience, of course.

Doug_C @25 ,
Quite so. No reasoning with denialists. At the present state of climate scientific knowledge, one can only be a "denialist/skeptic/contrarian" by being intellectually insane.
Fair enough, to point out to Dr Tim Ball (self-alleged "Professor of Climatology") how wrong he is . . . but in doing so, you are "playing to the audience", but you waste your time playing to him himself.
# Despite years of complete disappointment, I still read some of WUWT (and ClimateEtc ) from time to time, in the ongoing hope of discovering some important & valid argument against AGW. Nothing at all of that sort discovered, yet. (You may know ClimateEtc as a kind of upmarket WUWT , but with much less frothing-at-the-mouth in the comments columns.)
Occasionally in WUWT articles, there are some minor points of interest (points I had been unaware of). Most of the articles are tiresome in the puerility of their propaganda slant. The comments columns, I skim at speed (looking for the several "names" where I can expect sensible/insightful comments e.g. Nick Stokes, Steve Mosher, and a very few others — all of whom get excoriated by the hoi polloi of usual commenters). There is some entertainment value in viewing the bedlam antics of the usual commenters — of whom, half or more are in full denial of the GHE and the physics of CO2's radiative properties. And I confess to a feeling of Schadenfreude in viewing the insanity of these people's delusional Motivated Reasoning . . . but I find a spoonful goes a long way !
To return to Dr Tim Ball — if I see his name as author of an article, then I skip reading any of it. Along with a few other names there, such authorship indicates that reading the article will always be an utter waste of time. Utter. Similarly to reading the computations & ratiocinations of Monckton (or any inventor of a Perpetual Motion Machine) -— you know that somewhere in the verbiage is a serious error . . . and so you needn't bother reading any of it.
Monckton's various "re-calculations" of the 97% consensus, are in the same boat.

Thanks again for the replies.
I am well aware that the climate deniers wil use every trick in the book, honest or dishonest, to discredit climate science, including all those studies about the consensus, including the most recent that puts it at over 99%.
There is just no point in giving them a "gotcha".
Even if you think "mainly", "primarily", and "largely" are similar, it is not what was in the study which said "primarily" . And "extremely" in the following quote from the above article is clearly incorrect:
“Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities.”
Again, al I am saying is don't give them a "gotcha" (and I have seen this "gotcha" used many times on internet forums).

I am one of your Deniers. I am a retired geologist of over 40 years and will remind you that sedimentary geology is in fact the very essence of climate change so I am not completely ignorant of the subject. Quite simply, you have had almost 40 years and all the money in the world to prove your CO2 greenhouse gas theory and quite frankly ALL you have is a 97% consensus of scientists that are saying “Because We Say So”. There is not a single quantitative study in the last 40 years that proves the theory and quantitatively establishes CO2 concentrations to global warming and I can say without a shadow of a doubt that your group are not even working on one. WHY? Your 97% consensus might be good enough for you guys but most adults need at least some empirical proof to follo, and if there really was some proof, there would be no need for this comment or for your site. This article and the above comments show an almost unbelievable dismay that deniers can even exist and virtually anything they have to say is garbage in the wake of our overwhelming “consensus“. Well plugging your ears and yelling lalalalalala is not going to make the Deniers go away, nor is this continued Because We Say So. Seriously, there are thousands of scientists that simply do not believe your hypotheses or your theory and until you grant them some respect you will get NONE in return.
Moderator Response:[PS] Sloganeering without an ioto of evidence offered in support. Everything so far you have offered (not much) as counter-evidence has been a chimera and demonstration of your lack of knowledge and your readiness to believe what your suits your wishes instead of critical thought. Enough. (and the irony of statements are amazing).

Eclectic @24
I think some people are clearly beyond reach. There was an article entitled something like "Water vapour is the most important greenhouse gas not carbon dioxide, the scam revealed" by Tim Ball on a site not to be named.
I pointed out the basic contradiction in his primary theme, that water vapour is in fact present in the atmosphere in the form of a vapour that can be in multiple phases at the same time. While carbon dioxide is present there as a gas that is in one state only. Meaning if all the persistent CO2 was removed from the atmosphere, within decades almost all of the water vapour would have precipiated out of the cooler atmosphere.
His only response was some ad hominem, he didn't even bothering to address the science.
For some people this has stopped being a scientific issue. At best it is an economic or political issue, at worst it is religious. For these it is no longer an impersonal academic subject, it is a very personal one to the poiint where many deniers treat objective science as a personal attack.
How do you reason with people who have strayed so far from rational thought?

Nigelj @23 , perhaps you should say something more. New ideas?
I don't think there's a point in doing any hand-wringing about the imperfections of the past (and hindsight will always allow us to be wiser). But conceivably there might be some future way of making a brilliant chess-move to stymie the nit-pickers/nay-sayers in the deniosphere. Myself, I can't think what that move could be. As Philippe C. says @16 , the denialists will simply do what they do . . . with or without them having any ammunition to use.
For 2013, John Cook & associates were I'm sure very conscious of the likelihood of strong opposition to the Consensus study's conclusions . . . but they may not have anticipated the intense fury it stirred up. (Even more fury than a certain Emperor might have felt as his lack of clothes was pointed out.)
As you know, John Cook made the brilliant pre-emptive move of having an author-self-rated section in the study, to confirm the study's validity. (A confirmation which the denialists strenuously ignore, to this day.)
But all that being so, we still find Monckton & cronies going to vast lengths of absurdity in order to re-define 97% as e.g. 34% or 0.3% . In the face of such blatant and persistent insanity, I suspect it is futile to try to use reasonable evidence to convince the denialists. And the various consensus studies are aready done — and they are all essentially in agreement with each other — and there's probably no point now in re-confirming 97% or 98% or 99% .
What remains, is to "get the message out" more effectively into the ears of the general public.

I've been following this critical issue for more than half my life. In the mid 1980s the science was sound from what I could see and it has just gained confidence in the subsequent decades while the real world catastrophic impacts are seen all around us.
I find it inconceivable we are still discussing consensus or uncertainty on an existential issue. If there was even a 5% chance we are facing a global crisis of this magnitude it should result in immediate action and an end to meaningless speculation. But the chances even with conservative studies places the chances at over 95%.
There is no elite climate research institute that is about to release a groundbreaking study that this was all some mammoth misunderstanding and we'll all be fine now. Instead we are now in a position of trying to save as much of the biosphere as we can before the impacts of our actions become so catastrophic that there will be no coherent response possible in the chaos of climate change emergency after emergency.
The systemic cognitive dissonance over this issue is staggering. In Canada we are going into a fall election and one of the central issue still remains "is climate change real", there is a discussion of it this afternoon on our national broadcaster CBC.
Earlier this year the current government declared a "climate crisis" in Parliament one day and the next approved for the third time the controversial Trans Mountain pipeline expansion that would eventually be piping to terminal almost 1 million barrels of dilbit from the Athabaska tar sands. One of the most carbon intensive sources of energy on the planet. Our government has already spent $4.5 billion buying the current pipeline and will have to put in more than that to triple the line.
The fossil fuel sector here indicates no sense of emergency at all, the new Premier of Alberta which drives energy policy in Canada has effectively declared war on the science of fossil fuels driven climate change.
Jason Kenney touts $30M 'war room' but provides few details
There is no scientifically meaningful uncertainty left over whether climate change is occuring or the most likely forcing based on not just decades but centuries of science. Just politically motivated efforts to deny it.

Models are unreliable
Dr. Christy has a long history of presenting irrelevant, cherry-picked (tiny parts of the Sierras to argue that snowfall isn't decreasing, temps in Alabama which is relatively unchanged relative to other regions of the US), over-averaged (averaging rainfall over the US, ignoring that some regions are changing drier, others changing wetter), unnormalized (temp. extreme records without normalizing for the length of the observations at each station), and/or deceptively graphed data (his temp. record graph, which uses a variety of choices that all exaggerate variability in models/observations while his own look better than they actually are). And yes, I can point to concrete examples of each of those, most directly in the various testimonies he's submitted to Congress.
It's well worth taking any climate statement from Christy with both a large grain of salt and a careful examination of the evidence presented.

MA Rodger @20
Quantum Mechanics are the most powerful tool we now have to understand physical interactions at the level relevant to this issue. Before we had QM there was very strong evidence that carbon dioxide is the most important persistent gas in the atmosphere for moderating the global climate. After the development of QM that became far stronger as we then had a detailed explaintion as to why that has allowed experimentation to a degree that simply wasn't possible before.
And the science on carbon dioxide concentration in the atmosphere and its intimate link to global climate got stronger as more data was produced.
My point about uncertainty is it is being misrepresented by the denialist campaign, not placed in its proper context. There will never be 100% certainty on global warming in scientific terms because there is always room left to expand and adapt scientific theory as new information is acquired.
The standards of scientific certainty are far higher than in any other discipline, in legal terms the confidence on the link between CO2 emissions and the serious impacts have been recognized at the highest level a long time ago.
Massachusetts v. Environmental Protection Agency
The use of uncertainty in the case of global warming denial has nothing to do with advancing our understanding of the physical aspect of this phenomena, it is almost entirely political and economic in nature. It is simply not valid scientific skepticism.
I use the term existential in regards to global warming in the threat to the existence of human technological culture and society on a global level and the threat to a significant portion of the existing biosphere that is already in the process of accelerated extinction as climate conditions change far faster than many species can adapt to or migrant along with.
How can you refer to a process that is already well acknowledged to be underway as looney fringe?
We are already seeing massive dieoffs in the oceans in some of the most important ecosystems, if fully half the Great Barrier Reef system dies off in two years with a projection of almost all coral reefs systems and their diverse biotas gone by mid century, is that not a signficant loss of biodiversity from that one source.
Plus the research showing many insects populations in rapid decline, it's at an estimated 2.5% per year now. Many avian species are in rapid decline as well.
We now have an estimate of 1 million species at risk of extinction, that would have a profound impact on the overall biosphere.
Keep in mind that global warming and climate change is not taking place in isolation, it is the major human impact on the physical and natural systems on the Earth. But is taking place in the context of rapid deforestation of much of the worlds rain and temperate forests. In conjunction with a removal of a huge amount of species from the ocean for food with an equally massive polluting of the ocean environments.
Plus everything else we are doing to replace and remove those natural systems that make complex life possible on Earth in the quantity and diversity it currently has.
The truly loony fringe are those who think we can keep doing this for any longer without causing a systemic biological collapse.
Climate change denial is probably the most irrational organized behavior of our species yet.

Doug_C @19,
I rather disagree with your comment or at least feel it sould be better explained.
There are certainly differing qualities of work that comprise denialism. There is a large protion of that denialist work that is incompatable with very basic science. (I'm not sure that your mention of Quantum Mechanics is entirely correct or helpful to your assessment.) There is also a large protion of that denialist work that is incompatable with scientific data and thus contrdicts the resulting inferences that can be established by that data. None of this is a great distance from your comment.
What I don't see is any remaining denialist work that is properly supported by evidence. The entirety of the 3% sitting beyond the 'consensus' is surely incompatable with the scientific data and it is actually not a proper constituent part of the science.
What I particularly feel is a step too far is suggesting that:-
"The few percents of research that show doubt are simply there as part of the uncertainty that is inherent in science, it may as well be stated in terms of a 100% consensus when it comes to evidence driving policy on global warming."
This statement is saying that there exists "uncertainty ... inherent in (the) science" which is exactly the denialist message. The likes of, say, Richard Lindzen or Judith Curry who constitute the 3% outside the 'consensus' will argue that there is enough uncertainty to infer that Climate Sensitivity is low and thus AGW will not be a problem.
Now, we can see that Lindzen with his cloud iris theorising or Curry with her large natural climate wobbles are part of the scientific process. But the doubt they may have sown scientifically is long dispelled. What we are left with is the likes of Lindzen & Curry continuing to spread their now-unscientific message to policymakers as though it was legitimate science. It is unscientific to represent these messages as scientific and their messages ar become part of the "finely tuned stream of disinformation" (although the "tuning" may not be a conscious process on their part).
And masquerading as legitimate science, their message can then be presented as though it had the same scientific standing as the IPCC Assessment Reports rather than a loony fringe opinion, indeed one balanced by those who grossly exaggerate AGW.
I note you use the word "existential" without making plain to what it applies - ie what it is that has its existence threatened by AGW. I would suggest that it is but that loony fringe (that is balanced by the denialist looney fringe) that describes AGW as an existential threat to the human race when AGW is surely only an existential threat to the world economy whose collapse would not be a pretty sight and likely reduce human populations to a fraction of today's total.

Doug_C at 17:02 PM on 19 August 2019Millions of times later, 97 percent climate consensus still faces denial
The science of global warming and climate change is fundamental, for it to be overturned would take a revolution in our understanding of how the Universe works at a primary level.
Even before quantum mechanics were discovered in the early part of last century we knew that the Earth was much warmer than it should be. Over 150 years ago it was shown which gas in the Earth's atmosphere is almost certainly the cause of that warming, carbon dioxide.
Since the development of quantum theory we now have a very good idea of why carbon dioxide is so effective at moderating a planet's global climate. Heat emitted by the Earth is tuned to be absorbed by CO2 but sunlight arriving at the Earth is not. Adding or subtracting CO2 from the Earth's atmosphere creates a radiative imbalance that will be corrected by an increase or decrease in the global average temperature.
The most radical hypotheses would have the Earth not warming as the atmospheric concentrations of CO2 increase.
The few percents of research that show doubt are simply there as part of the uncertainty that is inherent in science, it may as well be stated in terms of a 100% consensus when it comes to evidence driving policy on global warming.
It is very clear from the current situation that the only thing preventing evidence driving policy with global warming in what is likely an existential phenomena is an artificial factor being introduced to prevent that. That is a very intentionally and finely tuned stream of disinformation that still blocks the valid application of what really is now one of the most fully studied and understood phenomena in nature.
And we also have a very well documented record of where that disinformation comes from.

BillyJoe @17 and prior ,
fair enough to point out the wisdom of keeping "ammunition" out of the hands of children & denialists.
But the track record of the climate-science denialists is that they *simply-do-not-care-a-damn* about truth, logic, evidence or honesty. (Philippe Chantreau @16 expresses it all exceedingly well.)
They will whip out a magnifying glass or a fine-tooth comb (please pick your metaphor of choice ! ) and look for a fly-speck on Mona Lisa's face . . . or look for a gnat on an elephant . . . and then they assert that this minuscule imperfection justifies denouncing the artistic worth of the Mona Lisa . . . or justifies ignoring the elephant in the room. They are a lost cause, altogether. Instead, any useful/interesting communication should be given for the benefit of the open-minded majority — who don't nit-pick, yet who are inundated with disinformation from "bad actors".
More explicitly on the 97% Consensus matter, as individuals we should step back and look at the "big picture". Which is a dichotomy situation — scientists are in two basic groups: (A) those who recognise that humans are the (approximately 100%) cause of the recent rapid global warming, or (B) those who do not recognize the evidence (i.e. who state that the global warming is non-existent or negligible ).
When you boil it all down, the question of largely , mainly , primarily etc, as "qualifiers" is irrelevant to the underlying situation. There are two groups of climate-knowledgeable scientists — those inside the consensus, and those outside. (Arguably, there is almost no-one with a foot in each camp, even though there are a few who claim to be ! )
BTW BillyJoe, if you look at the current-day consensus, it is well over 99% , according to the criterion of published science. The Consensus study by Cook et al 2013 is based on historic figures which are centered/averaged around the year 2005 approx. Quite a while ago !
Here in 2019 , there is no realistic debate about the climate consensus.

BillyJoe at 08:38 AM on 19 August 2019Millions of times later, 97 percent climate consensus still faces denial
Thanks for the replies.
I guess what I'm suggesting that no ammunition be given to climate deniers. As I said, I have seen this inaccuracy used against the idea that there is a consenus,
The cook paper has the following three categories of supporting papers:
1) Explicitly states that humans are the primary cause of recent global warming
2) Explicitly states humans are causing global warming or refers to anthropogenic global warming/climate change as a known fact.
3) Implies humans are causing global warming. E.g., research assumes greenhouse gas emissions cause warming without explicitly stating humans are the cause
Only the first category is consistent with the qualifiers "Largely", "primarily" and "mainly". But why not use the word actually used in the study, which is "primarily" and not apply it to the 97%.
When referring to the 97%, none of these qualifiers apply, becasue the second two categories - which are included in the 97% - do not use a qualifier at all. They simply agree that humans are causing global warming but say nothing about the extent to which humans are causing global warming.

Of course, you've seen it criticized in the denialosphere, that's what they do. They criticize anything and everything that does not suit their world view. Look critically at the stuff they embrace without any scrutiny and compare to the hair splitting about language. What does that suggest about the genuine character of their skepticism, their intellectual honesty, the very validity of their arguments?

Postkey @14,
While Monckton continually lays on the bunkum, his grand work Monckton, Soon, Legates, Briggs, Limburg, Jeschke, Whitfield, Henney & Morrison (2018-unpublished) 'On an error in applying feedback theory to climate' surely demonstrates the apex of his incompetence. (I should mention that some of the many co-authors may be unaware of their co-authorship.) According to the write-up on the planet Wattsupia, Monckton's grand work was supposed to set out how:-
1. It can be proven that an elementary error of physics is the sole cause of alarm about global warming – elementary because otherwise non-climatologists might not grasp it.
2. It can be proven that, owing to that elementary error, current official mid-range estimates of equilibrium sensitivity to anthropogenic activity are at least twice what they should be.
Monckton's bunkum certainly goes beyond incompetence, but Monckton's grand work takes it to a new mind-numbingly high level.

Billy Joe @10, the statement "what is the real percentage of climate researchers who agree that climate change is largely man-made?" seems much the same to me as using the terms mainly or primarily man made. These three words mean much the same thing. But it would have been better to just use one word for consistency.
The statement "Climate-warming trends over the past century are extremely likely due to human activities.” is a different thing referring to whether humans have a role. They should really have said "Climate-warming trends over the past century are extremely likely to have mainly been caused by human activities".
-
Eclectic at 12:26 PM on 18 August 2019Millions of times later, 97 percent climate consensus still faces denial
Fair comment, BillyJoe @10 .
Mainly , primarily , and largely . . . are all well-justifiable. But extremely is a bit . . . er . . . extreme . Yes, it's a logical consequence of the other three descriptors, but it doesn't present well.
Word choice is close to irrelevant, in some ways. The "climate denying blogosphere" will attack anything, anything at all, that it dislikes. Words, logic, arithmetic — all can be perverted to serve the denialist agenda.
# Only just today, I was admiring Lord Monckton's assertion that the climate science consensus was 0.3% rather than the more truthful 97-ish percent. And I am sure every reader here can think of multiple examples of other intellectual insanities promulgated in the "deniosphere".
And speaking of the good Lord M — I have begun reading the (very lengthy) "Lord Monckton's Rap Sheet" from the Climate Asylum blogsite [ bbickmore.wordpress.com ]. Amusing +++ . As the blogger says: "Nobody could make this stuff up". But we already knew we were dealing with a most peculiar personality !

BillyJoe at 10:23 AM on 18 August 2019Millions of times later, 97 percent climate consensus still faces denial
Maybe I'm just being pedantic here but you made four different statements about the consenus in this article, each one less emphatic than the one before:
Extremely:
“Multiple studies published in peer-reviewed scientific journals show that 97 percent or more of actively publishing climate scientists agree: Climate-warming trends over the past century are extremely likely due to human activities.”
Largely:
"So, what is the real percentage of climate researchers who agree that climate change is largely man-made?"
Primarily:
"Our team’s review of the abstracts yielded a 97.1 percent consensus that humans are primarily responsible for recent global warming;"
Mainly:
"we demonstrated that between 90 and 100 percent of climate scientists and their peer-reviewed research agree that humans are the main cause of recent global warming"
I have seen this criticised in the climate denying blogosphere. They quote the more emphatic statements and show with quotes from the paper that this is not justified.
Would you please clarify.

I have supported one or another variation on the Carbon Tax for most of my adult life (a long time for an 80-something). In discussions with people of a wide range of political, relligious, socio-political, ethnicity etc orientations, I have found almost all to be amenable to some form of the Carbon Tax, once they understand the issues.
I cannot prove it, but I really believe that nail-the-flag-to-the-mast opposition of vested interests is that they fully understand it will work just as intended, if properly implemented.
Why the opposition of so many well-intended self-declared climate champions? I think of Van Jones. One morning my wife and I were listening to him on television. She observed that he is charismatic, articulate and handsome but… she wished "God had granted him a more generous serving of brains."

Nick Palmer @6, while libertarian anti government thinking is obviously at the heart of the most vociferous climate denial, some of the general public who are in denial vote left, so dont think like this and so probably just resent change. I doubt they are are all hard left eco fascists. It's a whole other category of denial, but probably one open to persuasion because it's not based too much on ideology.
But I agree about the motivations of oil companies and their reasons for supporting certain think tanks. As you imply one of their biggest fears is probably heavy handed government control so they might accept a carbon tax in preference to something more draconian. But only grudgingly.
The basic issue is the free market has proven entirely incapable of fixing the climate problem with literally the only progress coming from governmnet subsidies, taxes and the like. There are more heavy handed anti capitalist approaches and massive government programmes like the GND. I think society has to make a choice of what approach they prefer, carbon fee and dividend looks the smoothest and least disruptive and most business friendly to me, but the longer that is deferred the less time we have which will leave only more heavy handed government responses. So business better understand this. Capitalism better watch out!

Nick Palmer@6,
The Delayers of Correction are an important part of the big picture. Their efforts to maximize their personal gain while delaying the understood required corrections are fairly obvious.
After 30 years of powerfully supporting the incorrect popular denial of climate science, they are grudgingly accepting (not pushing for) a gradual introduction of Carbon Taxes. That action, that by itself, will only be a minor help in achieving the required 2.0 C limitation on human impacts (and will not achieve the real need to limit the warming impacts to 1.5 C).
If those pursuers of maximum personal benefit (status) from fossil fuels had supported action like carbon fees starting 30 years ago there would be less evidence of how harmfully correction resistant the developed systems are. Now there is ample evidence that the current developed systems of popularity and profit are very harmfully correction resistant (and not just regarding fossil fuels).
Allowing the developed systems to 'self-correct' (harmfully slowly) for the understood harm that is undeniably being done is not a solution. In fact there is a significant chance that without external influence and changes of the rules and penalties, the games of popularity and profitability will not helpfully self-correct, they will get worse.
Defending the developed systems against correction, and pushing for them to be even more harmfully free from thoughtful considerate governance of what is allowed in the competitions for popularity and profit, implies accepting that the human developed systems and resulting status-quo need to be allowed to produce a significantly greater amount of warming. That will be the result of not rapidly correcting the undeniably harmful resistance to correction that is being baked into the systems. And it is undeniable that the delay of action through the past 30 years has created the bigger problem today that is forcing the need to more dramatically correct the system and the results it has developed (and the more powerful resistance to that correction may be exactly what the delayers of action through the past 30 years had been hoping to develop).
The developed human systems have tragically proven the need for dramatic correction, and the harmful powerful developed resistance to correction.

I thought I'd explained my suspicions as to why oil company execs use organisations who use denialist rhetoric to sway public opinions! I am more and more convinced that Big Fossil Fuel, as an entity, no longer believes denialist misinformation, this can be infererred because nowhere on their corporate websites these days will one find a trace of denialism - I think that is history...
I think they use lobbying organisations, who do still use the 200+ arguments that this website combats so well, not because they believe in them but because they have a proven ability to muddy the waters and push the buttons of the political forces they want to influence. It is clear that some of the command and control 'solutions' put forward by the more extreme campaigners and environmental organisations are based largely on an anti-capitalist hard left viewpoint which seems to want to completely dismantle our industrial society.
Whether Big Fossil Fuel is wrongly or rightly taking a Macarthyist 'Reds under the Bed' approach is unclear but, as I hinted above, there are solutions that businesses feel would work better for them and society which would sidestep draconian socialistic government type interventionist methods. It is notable that some oil majors have introduced a notional carbon tax into their accounting procedures in recent years, preparing for when the world may decide to go for a 'carbon tax and dividend' modified freemarket approach, like the similar method (Cap and Trade) which worked well to reduce acid gas and smoke stack particulate pollution in the early 90s -

"1. If CO2 isn't driving the initial temperaturte rise, then what reason is there to cite it in subsequent rises?"
Ah... because that's the difference between a forcing and a feedback.
Without that CO2 feedback the initial orbital forcing would only produce a very small change in temperature. The resulting feedback is what gives us glacial/interglacial cycles.
Regardless, the effect is the same. CO2 is a gas with radiative properties. Adding CO2 to the atmosphere will cause the planet to warm. Add lots of CO2 and the planet will warm a lot.

Good list and explanations, but I think you also have to add people with strongly vested interests in fossil fuels, such as oil company executives, transport sector executives, people who own cherished ICE cars etc, some of whom appear to be in denial of the science and / or mitigation in my experience, and it stands outside of right wing political convictions or a galileo complex. Not everyone who votes left wing supports either the science or mitigation, because polling tells us that suggesting they are just attached to fossil fuels at a deep level.

Joe Wiseman, I get your point, but I doubt that many scientists fit the sociopathic label. Out of curiosity I had a look at what occupations attract sociopaths and why here. There is no mention of scientists, and the sociopathic personality described in the article doesn't seem to sit that comfortably with the scientific profession.

Youjaes @376 , LOL but please do not bite me ;-)
1. . . . was expressed rather ambiguously. For each rise (or fall) of temperature in glaciation/de-glaciation, the first 10% is caused by slight variation in "insolation" and the subsequent 90% is caused by change in CO2 level (i.e. change in GreenHouse Effect). Rough figures, of course.
So your comment #1 was 90% wrong. Ah, if only you had read the Original Post and subsequent comments! ;-)
2. Ice core data conforms with the 10% / 90% description (above).
No problemo !
3. The so-called (but poorly-named) GreenHouse Effect [ = GHE ] has already been shown with data from satellites. Long ago. ( But half the crazies at WhatsUpWithThat blog . . . are still in full denial about it all ! . . . even though the good Mr Watts occasionally whispers that they're wrong to deny it. )
No need for backyards or front yards being involved.
4. As global warming has proceeded, wind speeds have slowed very slightly, I am told. But WUWT has made a mountain out of a molehill, on that. Kind of a nothingburger. Strange, since WUWT is usually trying to make molehills out of mountains ! ;-) ;-) ;-)

Dana, I'm not sure continuing to demonise the fossil fuel industry by implying they are still sponsoring 'denialism' is useful anymore. No doubt they continue to use lobbying think tanks etc that use denialist propganda techniques to influence policy makers, and the general public, but a more sophisticated appreciation of matters than 'Big Oil bad' seems more appropriate these days. I think it far more likely that Big Fossil Fuel uses these lobbyists, not because they want to deny the science but rather that they want any proposed solutions to mitigate global warming to be as business friendly as possible. In short, BFF fears imposed heavy handed bureaucratic or left wing type solutions so uses lobbyists to campaign against this. As the well known denialist fighter Potholer54 (Peter Hadfield) has written, there are right wing low government solutions too.
Anyone who routinely takes on denialists, as I've been doing for decades now, should rapidly realise that there are four basic types of motivation. In order of numbers I would say most are A) right wing/libertarian deniers B) left wing deniers C) fundamentalist Christian deniers and, finally D) Galileo wannabes.
A's deny because they are led to fear that climate science is faked up by the left wing, the 'New World Order/Agenda 21' and politicos who, they assert, only fund scientists who toe the line. They are led to fear that climate science is all a plot to increase taxes and government control, to take away their 'freedoms' (and, sometimes, guns..). Some will even, adopting a faux humanitarian stance, assert that climate change policies are a bad idea because they will hurt the 'poor peoples' of the world by denying them cheap energy... This attitude is not helped by those of the more fanatical climate campaignes who assert that the capitalist system is the real problem and only by doing away with it completely, will we succeed - it's no wonder right wingers strongly resist this 'watermelon' (green on the outside, red on the inside) motivation!
Bs deny, or at least did historically, although there still exists some far fascist left denialism such in 'Spiked', because they see climate change policies as denying the third world the cheap energy they need to develop out of poverty and thereby threatening the richer nations.
Cs deny the science because they think God the designer is in charge, and so loves us that he wouldn't allow us to significantly destabilise the climate to our detriment, so he must have designed in feedbacks to prevent this which means they think that IPCC projections are a crock of s***.
Ds are probably the most irritating because they believe their hypotheses are superior to all others. Tend to believe that climate science is invalidated by the laws of thermodynamics, cosmic rays, variations in the magnetosphere.
I think there is evidence that support for the denialoshere is imploding and what will remain will be political rhetoricists using old denialist zombie memes to sway the minds of the public so they vote against the implementation of solutions that the 'other side' likes... -
One Planet Only Forever at 01:26 AM on 17 August 2019Millions of times later, 97 percent climate consensus still faces denial
Joe Wiseman@1,
It is an error to presume that 4% of climate scientists are sociopaths and that 97% consensus means that 25% (not 1%) of the climate scientists who are sociopaths accept the developed and improving understanding of climate science and the related corrections of developed human activity.
Building on Joe Wiseman's point about the science showing that a significant percentage of the population lack the instinct to care about how their actions harm other life forms including future humans (more words, but a clearer statement of the problem than the term 'sociopath'), it is important to understand that the competitions for perceptions of status based on popularity and profitability encourage people to compromise their instinct to be helpful or caring, developing harmful results that can powerfully resist correction.
Tragically for the future of humanity, the socioeconomic-political systems that develop tend towards harmfully undeserving people becoming the Higher Status and more powerful people. And that includes a higher percentage of the 'people who lack the instinct to care about how harmful they are' among the Higher Status than in the general population (google it).
And that higher percentage of the instinctively harmful (because of a lack of the instinct to care or be helpful) among the winners is the evidence that the system they were Winners in promoted and excused that type of behaviour. In those systems others who have the instinct to care are ata competitive disadvantage and are encouraged to compromise their Caring instinct for other interests or instincts. And Jonathan Haidt has identified the set of human Instincts that can work against the Good Work of developing a sustainable constantly improving future for humanity.
The following is the Wikipedia presentation of Haidt's 'Human instinctive/reactive' (not thoughtfully considered) Tastes that he incorrectly identifies as Moral/Ethical (having read Haidt's book I know that Wikipedia has correctly presented them):
"1) Care/harm: cherishing and protecting others; opposite of harm
2) Fairness/cheating: rendering justice according to shared rules; opposite of cheating
3) Loyalty/betrayal: Loyalty or ingroup: standing with your group, family, nation; opposite of betrayal
4) Authority/subversion: submitting to tradition and legitimate authority; opposite of subversion
5) Sanctity/degradation: abhorrence for disgusting things, foods, actions; opposite of degradation
6) Liberty/oppression: objection to coercion by a dominating power or person; opposite of oppression"
Any of the Other 'passionate impulses' can result in a contravention of the Help/Harm consideration (even a claim of needing to be Fair can be abused to defend harmful unsustainable actions - compromising helpfulness in order 'to be fair to those who want to be harmful'). It needs to become understood to be Unethical and Immoral to allow those Other 'instincts/impulses' to count as credits against the Pure thoughtful Ethical consideration/determination of a help/harm evaluation of merit. They are only ethical if their Means and Ends fit fully within the circle of Help/Harm limitation. And it can be seen that political groups Uniting the Right prey on those other instincts to collectively harmfully fight to resist progressive helpful correction.
So the required correction for the benefit of the future of humanity requires the caring instinct to Govern over all other interests. And that will require the people perceived to be higher status to prove that they deserve their status by consistent helpful actions. And that will require legal mechanisms for lower status people, and the future generations of humanity, to effectively penalize any high status person whose actions are contrary to help achieve and improve on the Sustainable Development Goals and similar developed understandings of what it takes to be Deserving of Status, deserving to be admired or valued.
And the Propaganda Model developed by Edward S. Herman explains how competition for popularity and profit can and does make up stories that harmfully resist the required corrections of understanding.
Admitting that the games are massively rigged and require significant correction is a Good Start.
And exposing the harmfulness and unacceptability of the people who choose to resist the correct understanding of the consensus regarding climate science is a powerful mechanism for pushing for the required corrections of understanding.

Okay, I'll bite you back.
1. If CO2 isn't driving the initial temperaturte rise, then what reason is there to cite it in subsequent rises?
2. Did you forget about the ice core data? Temperature goes up, then temperature goes down before yhe CO2 does. Were you not paying attention?
3. Go ahead, do some.
4. Do you normally contradict yourself? Decreasing surface wind speeds is associated with increasing surface temperatures. Decreasing global surface wind speeds means what, no global surface temperature change?
Do pay attention.

From the depths of the Last Glacial Maximum 20,000 years ago, CO2 levels increased due to warming from Milankovitch forcings, which then triggered an immense increase in atmospheric CO2, which drove the bulk of the temperature increase needed to drive the world from full glacial phase into the full interglacial world of today.
In short, the initial warming was indeed triggered by the Milankovitch cycles, and that small amount of orbital cycle-caused warming triggered the CO2 release from the Southern Oceans, which caused most of the glacial-interglacial warming. CO2 led and was the primary driver behind most of the glacial-interglacial warming.
From Parrenin et al, we see that temperatures and CO2 levels in Antarctica rose synchronously, with no lag in either measurement.
According to the Shakun et al data, we see that increase in atmospheric CO2 led the increase in global temperatures for the remainder of the globe.

OK, I will take the bait.
You clearly are not very well informed on climate science and you have not spent anytime thinking about the points you make. Let me give you some ideas to think about. If you have more questions there are plenty of knowledgeable people who will (sincerely) help if you ask in good faith.
1. The CO2 may not be driving the initial temperature rise but there is no reason to discount it in subsequent rises.
2. Is CO2 still elevated? What events are you talking about? I would guess Milkanovich cycles may answer your question.
3. Who says you cannot measure greenhouse effects with "backyard" experiments? Why do they have to be "backyard"? Are "backyard" experiments somehow more convincing than frontyard experiments? I suggest you read something about the greenhouse effect as you do not understand it.
4. Um. Yes, wind can reduce/increase local temperatures. What has that got to do with global warming?
-
youjaes at 21:57 PM on 16 August 2019Increasing CO2 has little to no effect
I'm looking at the comments and wondering about what I think are obvious things.
1. The 800 year CO2 lag should indicate that CO2 isn't driving temperature.
2. If increased CO2 raises temperature, what is causing the subsequent temperature crashes since CO2 is still elevated?
3. If you can't measure greenhouse gas effects with 'back yard' science experiments, what makes anyone think there is an effect in the first place? Yes, CO2 is a 'greenhouse gas' where people add over 1000 ppm of CO2 to help the plants grow. Apparently that much additional CO2 isn't noticably changing the inside temperature, so why would a 100 ppm change in the atmosphere have any measurable change in planetary surface temperatures?
4. There is another reason why surface temperatures can increase, specifically, reductions in surface wind speeds, which is occuring. Here is a report complaining about it.

MA Rodger at 20:09 PM on 15 August 2019Models are unreliable
rupisnark @1151,
The basic message is as Eclectic @1152 says, Christy is trying to pull the wool over your eyes. It may be he has managed to pull the wool over his own eyes as well. That would square with him being in denial over climate change.
And Eclectic @1152 is correct to say that AGW is a phenomenon at the TOA but Christy is not discussing TOA. He is indeed obfuscating.Your first point, that global evaporation can vary by large amounts month-to-month (Christy quoted examples of 24 and 27 'units' in his talk, a variation peak-to-peak of some 12%, a little more variation than his words in GWPF Note 17 - "In other words, evaporation might be 24 one month, but it might be 26 the next."), looking at actual monthly variation, the maximum variation of measured global monthly precipitation over decads (there's a graph of it 1980-2011 on this web-page) is about 12% peak-to-peak. Thus to say such a variation could occur "one month" to "the next" is pure exaggeration. The typical variation month-to-month is far far smaller.
And it is far far smaller doubly-so. Your point that 12% is a big value is twice incorrect. As they say '100% of naff-all is still naff-all.' And the typical variation month-to-month in surface heat flux due to precipitation is naff-all relative to the total precipitation which in turn is a small component of the total surface heat flux.
And your inference that such variation in precipitation would be even larger at longer timescales, "annual, let alone centennial fluctuation" is not correct. Over longer timescales the variations will tend to average out, although there will be trends caused by the likes of AGW.
You also suggest that longer term fluctuation could exist in "the many other variables of both inut (eg amount of solar radiation) and output." The solar cycle resilts in TSI wobbling by 1Wm^-2 peak-to-peak. In Christy-units that would be 0.07 units peak-to-peak (of the 11-year cycle) but when averaged out over longer periods the measure would be far far smaller. That this is a minor effect climate-wise is evinced by the absence of any noticable 11-year climate cycle.Your second point is that "Christy’s diagram does NOT imply 0.5 units is retained." I don't know why you would suggest such an implication. In GWPF Note 17 Christy states "The extra carbon dioxide we have added to the atmosphere amounts to about an extra 0.5 of a unit of the 100 downwelling from the air." So if the CO2 is there, surely the 0.5 units are there. I see no evidence of any implication that the forcing is not permanent.
You further suggest that there is "extra heat being lost in the troposphere" which might provide "one possible reason," this proposal "backed up" by an area of the upper troposphere that has not warmed in line with modelled projections. I don't follow the logic. By what mechanism would a cooler part of the upper troposphere constitute a sink for a heat flux of 0.5 Christy-units? -
Eclectic at 14:47 PM on 15 August 2019Models are unreliable
Rupisnark @1151 ,
how does evaporation qualify as an input or output of the planet?
"Top Of Atmosphere" [TOA] is normally taken as the planetary boundary, concerning the gaining of heat/energy and the losing of heat/energy (i.e. concerning the equilibrium or disequilibrium of energy flux re global warming or cooling). Evaporation & condensation move the heat around within the boundary ~ this plus convections of ocean and atmosphere do variably affect the distribution of heat/energy . . . but this is all part of the "averaging" which contributes to the TOA energy flux.
The multi-decadal average is the determinant of climate change. Dr Christy is obfuscating.
-
rupisnark at 05:05 AM on 15 August 2019Models are unreliable
@MA Rodger 1141
You state: “The constant 0.5 imbalance is "almost" (Christy also says "much more" which is a poor description - "more" yes, "much more" no.) the same size as the occasional fluctuations, his examples being monthly wobbles of +/-1.0 & +/-1.5.”
But Christy’s examples, which you appear to accept, take for instance evaporation of 24 average increasing to compared to 27 over a monthly which is actually a 12.5% change in the amount of heat lost through evaporation. That is clearly not small and that is just a monthly rather than annual, let alone centennial fluctuation of one of the many variables of both inputs (eg amount of solar radiation) and outputs.
Christy’s diagram does NOT imply 0.5 units is retained. His diagrams show in=out.
I think Christy believes one possible reason for the difference is explained by the extra heat being lost in the troposphere. This backed up by Steven C Sherwood and Nidhi Nishant “ tropospheric warming does not reach quite as high in the tropics and subtropics as predicted in typical models”. https://iopscience.iop.org/article/10.1088/1748-9326/10/5/054007/pdf. -

"Great question. Also an intellegent question. It's something that many Climate Scientists have tried to brush off with a "yes, but CO2 then becomes the forcing agent" as if autocorrelation is only done at the beginning of each interglacial phase. It isn't. It's done over the entire time series, including when CO2 is suppose to become the forcing factor."
Let's break this down. Firstly, do you accept that glacial cycle is orbitally forced? Further discussion makes no sense if this is not the case.
Assuming you accept orbital forcing, how do you explain why SH glaciation is synchronous with NH (since orbital forcing is anti-phased). Its easy if you accept known physics (GHE included) but you apparently want to deny that increasing CO2 will warm the planet.
Secondly, how about linking to some more actual detail about your "autocorrelation" stuff. I dont get your point and I certainly not clear to me what you think you are proving. The relationship between T and CO2 is still somewhat unconstrained but is clearly non-linear and involves multiple mechanisms operating on scales from years to millenia.
What is the basis for your understanding of "their ever decreasing estimates of how much CO2 impact climate". I certainly do not get that from successive IPCC reports.
You seem to be implying that papers on direct observation were arguments from correlation. This is not the case. The arguments in those are of the form, "fundimental physics allows us to predict what observations done by this method would show. Let compare model results with observation".
So from this, you compute how much much the radiation at the surface will change with GHG concentration change - and measure it. You look at how GHG changes would change the spectrum of outgoing or incoming radiation - and measure them. That is what those papers do. Hansen and Sato compute forcing from change in GHG using ice core bubbles as proxy for atmospheric concentration, and compute the change in albedo based on sealevel etc, and finally the global solar irradiation change from milankovitch. Climate theory would expect icecore temperature to be related to that forcing calculation extremely closely and that is what is observed. A failure to observe that would be evidence against.
Can I ask whether you accept Planck Law? ie, if irradiation of surface increases, then it temperature must rise.
Finally, climate change at present appears to be forced by GHG change. The feedback mechanisms that apply during ice ages wont cut in any significant way for 100s of years. The natural system is still moping up about half of our emissions which make 616 invalid (actually so many issues with this, its hard to know where to start. You need 30 year averages remove the internally variability, especially ENSO.)

MA Rodger at 00:39 AM on 14 August 2019Models are unreliable
I had a second, more focused look at Sarkomaa & Ruottu (2019) and find it a worthless piece of work.
Clouded by ♥ a confusing use of English & ♥ not-scientific presentation, these elderly Finnish professors provide an account riven with ♥ unsupported but controversial assertions, ♥ silly mathematical constructs and ♥ mathematical models that entirely fail to capture the workings of climate (let alone AGW).
Such a conclusion does need some further demonstrating.
......
♥I don't think their poor use of English needs demonstrating.
♥The lack of scientific presentation is shown many times. As an instance, they insist (p6) that:-
"If all linear radiation coefficients of clouds are set zero, the SRclimate model of Appendix 4 [and of their design] calculates about 100 W/m2 increase of solar energy flux to the ground and about 13 °C increase of the mean temperature of the ground. This agrees with the generally known fact that when cloud comes in front of the sun temperature decreases. Thus, IPCC’s climate change claim should be based on calculations with negative, instead of the positive cloud feedbacks."
Their "generally known fact" is of course simplistic nonsense and the absence of "general agreement" is all too evident in Zelinka et al (2017), a reference cited by Sarkomaa & Ruottu. Yet this diparity is not addressed by Sarkomaa & Ruottu who instead treat us to mention of a peurile interchange with Finish climatologists (p6).
♥The lack of science extends to a large number of obviously unsupported controversial assertions. An example:-
"Figure 1[*] Figure shows that the mean temperature of the ground has been always varied and it is sure, that the variation is going to continue. During the latest 50 thousand years the mean temperature of the ground has increased about 6 ºC and that the increase is going on. On long term decreasing trend can be noticed which is due to inevitable decrease of nuclear reactions in the sun. The hundreds year trends are due to variation of surface temperature of the sun. These variations have nothing to do with CO2 concentration in the atmosphere."
[* on Page 20. Figure plotting global temperatures of last 2Myr based on Snyder (2016), Zachos et al (2008), Lisiecki & Raymo (2005) and 800kyr of Vostok ice core data scaled at 1:2. These first two references contradict the "nothing to do with CO2" assertion.]
♥The nonsense is aided by the use of silly mathematical calculations presented seemingly for no reason. Their equation 4.16a p52 presents an easily understandable example, it being a formula for an average global temperature for time t=0 to t=a obtained by integration over the surface of a sphere. Quite how anyone would obtain formula to use in such an integration of average temperature of a planet (Sarkomaa & Ruottu describe it as being "entirely impossible") or for what purpose they present the formula is not explained.
♥Perhaps their main conclusion is expressed within their blog commentary of their analysis which translated @1145:-
"It follows from Planck's Law and the equation for spectral radiance that the effect of increasing atmospheric carbon dioxide on global temperatures is asymptotic, not progressive."
Here Planck's Law is what within AGW is usually expressed in climatology as the Stefan-Boltzmann relationship although here its exact application is not entirely clear.
"Spectral radiance" is described as "The basic physical concept of radiative heat transfer" (p66) and the "asymptotic" level (which is found to be 288K, the average global temperature which the modelling is set to) appears to be the equilibrium temperature which, of course, will be arrived-at in a manner "asymptotic, not progressive" (as in their eq 5.1) as the equilibrium temperature is approached. The modelling is then used to demonstrate that there will be no significant increase in surface temperature if there is more CO2 in surface air. The result should actually be zero because the air has not been allowed to increase in temperature (the AGW effect is not driven by surface phenomenon) and so cannot have any extra radiative effect to warm the surface. All that happens is the IR path-length decreases within the CO2 absorption bands at the same rate at which the amount of CO2 emiting this IR increases - thus zero effect.
Sarkomaa & Ruottu actually report that in the absence of other GHGs, the "increase of carbon dioxide concentration has strong influence on the mean temperature of the ground." Their Fig 5 p73 is missing the 0.0005 'multiplier' plot but the other plots would suggest a 'climate sensitivity' of 1.0ºC at 0.0005 but this value for 'sensitivity' looks to be increasing exponentially as the 'multiplier' decreases. So if the 'multiplier' were reduced to zero, climate sensitivity (for a CO2 doubling) would be infinite.
But with the 'multiplier' at 1 and GHGs properly represented in their model, the "increase of carbon dioxide concentration has practically no influence on the mean temperature of the ground." Yet, as stated above, given what they are apparently modelling (which is not climate sensitivity), the answer should be zero. -
