The New ‘Consensus’ On Global Warming – a shocking admission by "Team Climate"

From the “well maybe there was a hiatus after all” walkback department. Even Mann is on board with this paper.


A scientific consensus has emerged among top mainstream climate scientists that “skeptics” or “lukewarmers” were not long ago derided for suggesting — there was a nearly two-decade long “hiatus” in global warming that climate models failed to accurately predict or replicate.A new paper, led by climate scientist Benjamin Santer, adds to the ever-expanding volume of “hiatus” literature embracing popular arguments advanced by skeptics, and even uses satellite temperature datasets to show reduced atmospheric warming.

More importantly, the paper discusses the failure of climate models to predict or replicate the “slowdown” in early 21st century global temperatures, which was another oft-derided skeptic observation.

“In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble,” reads the abstract of Santer’s paper, which was published Monday.

“Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed,” reads the abstract, adding that “model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.”

The paper caught some prominent critics of global climate models by surprise. Dr. Roger Pielke, Sr. tweeted “WOW!” after he read the abstract, which concedes “model tropospheric warming is substantially larger than observed” for most of the early 21st Century.

It’s more than a little shocking.

Santer recently co-authored a separate paper that purported to debunk statements EPA Administrator Scott Pruitt made that global warming had “leveled off.” But Santer’s paper only evaluated a selectively-edited and out-of-context portion of Pruitt’s statement by removing the term “hiatus.”

Moreover, climate scientists mocked Texas Republican Sen. Ted Cruz for talking about the global warming “hiatus” during a 2015 congressional hearing. Instead, activist scientists worked hard to airbrush the global warming slowdown from data records and advance media claim that it was a “myth.”

Santer and Carl Mears, who operate the Remote Sensing System satellite temperature dataset, authored a lengthy blog post in 2016 critical of Cruz’s contention there was an 18-year “hiatus” in warming that climate models didn’t predict.

They argued “examining one individual 18-year period is poor statistical practice, and of limited usefulness” when evaluating global warming.

“Don’t cherry-pick; look at all the evidence, not just the carefully selected evidence that supports a particular point of view,” Santers and Mears concluded.

Cruz’s hearing, of course, was the same year the National Oceanic and Atmospheric Administration (NOAA) released its “pause-busting” study. The study by lead author Tom Karl purported to eliminate the “hiatus” from the global surface temperature record by adjusting ocean data upwards to correct for “biases” in the data.

Democrats and environmentalists praised Karl’s work, which came out before the Obama administration unveiled its carbon dioxide regulations for power plants. Karl’s study also came out months before U.N. delegates hashed out the Paris agreement on climate change.

Karl’s study was “verified” in 2016 in a paper led by University of California-Berkeley climate scientist Zeke Hausfather, but even then there were lingering doubts among climate scientists.

Then, in early 2016, mainstream scientists admitted the climate model trends did not match observations — a coup for scientists like Patrick Michaels and Chip Knappenberger who have been pointing out flaws in model predictions for years.

John Christy, who collects satellite temperature data out of the University of Alabama-Huntsville, has testified before Congress on the failure of models to predict recent global warming.

Christy’s research has shown climate models show 2.5 times more warming in the bulk atmosphere than satellites and weather balloons have observed.

Now, he and Santer seem to be on the same page — the global warming “hiatus” is real and the models didn’t see it coming.

Santer’s paper argues the “hiatus” or “slowdown” in warming “has provided the scientific community with a valuable opportunity to advance understanding” of the climate system and how to model it.

What’s interesting, though, is Santer and his co-authors say their paper is “unlikely to reconcile the divergent schools of thought regarding the causes of differences between modeled and observed warming rates.”

In other words, the “uncertainty monster” is still a problem.

Causes of differences in model and satellite tropospheric warming rates

Benjamin D. Santer, John C. Fyfe, Giuliana Pallotta, Gregory M. Flato, Gerald A. Meehl, Matthew H. England, Ed Hawkins,

In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble. Because observations and coupled model simulations do not have the same phasing of natural internal variability, such decadal differences in simulated and observed warming rates invariably occur. Here we analyse global-mean tropospheric temperatures from satellites and climate model simulations to examine whether warming rate differences over the satellite era can be explained by internal climate variability alone. We find that in the last two decades of the twentieth century, differences between modelled and observed tropospheric temperature trends are broadly consistent with internal variability. Over most of the early twenty-first century, however, model tropospheric warming is substantially larger than observed; warming rate differences are generally outside the range of trends arising from internal variability. The probability that multi-decadal internal variability fully explains the asymmetry between the late twentieth and early twenty-first century results is low (between zero and about 9%). It is also unlikely that this asymmetry is due to the combined effects of internal variability and a model error in climate sensitivity. We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.

“..Santer and his co-authors say their paper is “unlikely to reconcile the divergent schools of thought regarding the causes of differences between modeled and observed warming rates.”
Modeled warming rates are a ‘school of thought’ and reflect a desired political outcome.
Observed warming rates reflect reality of known science.

Is it possible that hyperventilating snowflakes sequestered enough co2 to make up the difference?


I believe they’re “late to the party” even when they host the party. That’s why they have such bad manners.

Mark Fife

Hyperventilating actually causes you to exhale more co2 and sequester more oxygen. Enough to affect a shift in the body’s PH balance. Initially this makes you feel like you are not getting enough air so the natural reflex is to breath faster. Kind of a vicious cycle, especially for people prone to panic attacks.
Armed with this knowledge we now know just how damaging marching and protesting can be to the environment. If these moralistic little snowflakes really cared about saving the planet they would stay home in enclosed, dark spaces, avoid exerting themselves, and whisper quietly. And above all remain calm!


It is so hard to reconcile the hypothalamus with the frontal lobes when your limbic system holds sway over rational thought!

Javert Chip

That’s what I always say in situations like this….

That is why Marxism and “progressivism” have so much appeal. They are basically primal and counter-evolutionary. Individual liberty of property and thought is a fairly recent development of human evolution.


…. It’t got more to do with the Wallet nerve than anything else….. 😉

Dr. S. Jeevananda Reddy

Observed warming rate includes several components including natural variation, greenhouse effect component, non-greenhouse component. Also it is a biased estimate based on the distribution of met network both on the land and in the water with time and space — to overcome this groups made adjustments that vary with group to group.
Dr. S. Jeevananda Reddy

Paul Mackey

I think Dr Curry’s observation that two version of the same dataset had differing values for the same year in the past, shows the adjustments are incorrect. I would expect that simply adding a few months of additional data ( extending the time series) should not change existing values in the time series dataset.
Can you imaging this in any other field? Say, adding this months closing stock prices to the historical series changing the price observed 30 years ago? It is ludicrous.


The paper sounds like the warmists trying to signal they are willing to work with the Trump Admin if they can keep their government research grants.

Rowland P (UK)

Benjamin Santer is one of the main culprits to instigate the global warming scam:
As lead author of Chapter 8 of the 1995 IPCC Report, he took wording agreed to by fellow chapter authors and modified it considerably. For example, the group wrote,
1. “None of the studies cited above has shown clear evidence that we can attribute the observed [climate] changes to the specific cause of increases in greenhouse gases.”
2. “While some of the pattern-base discussed here have claimed detection of a significant climate change, no study to date has positively attributed all or part of climate change observed to man-made causes.”
Under Santer it became
1. “There is evidence of an emerging pattern of climate response to forcing by greenhouse gases and sulfate aerosols … from the geographical, seasonal and vertical patterns of temperature change … These results point toward a human influence on global climate.”
2. “The body of statistical evidence in Chapter 8, when examined in the context of our physical understanding of the climate system, now points to a discernible human influence on the global climate.”
This is from

Joe - the non climate scientist

I like Mann’s previous explanation –
The pause was an artifact of the AMO/PDO – but the enhanced warming during the warming phase of the AMO/PDO had nothing to do with the accelarated rate of warming during the 1980/90’s

Joe - the non climate scientist

In other words – it shows the dishonesty of the climate scientists – ignoring the ocean cycles that have been prominent in the temp records since the 1850’s
Or is shows the ignorance of the climate scientists – not knowing about the ocean cycles even though they have been prominent in the temp records since the 1850’s
Or it shows both the ignorance and the dishonesty

I think you forgot greed! Then there’s the other deadly sins.


Ingnorance, dishonesty, and greed, Yes, these are our primary weapons against heresy. And stupidity. Ingnorance, dishonesty, greed, and stupidity… Nobody expects the Spanish Inquisition.

I seem to have heard recently that “the love of theory is the root of evil” somewhere on you-tube…

Richard M

While it is good these folks are admitting something that has been obvious for years, they are still in denial that all of the variability could be completely due to ocean cycles.
I think that Fyfe is the key person here. He is probably the one who is showing them the math does not support what they want to believe.

All the climate variability could be due to measurement errors, inaccurate infilling, improper “adjustments” and leftist ‘thumbs on the scale’.
Even if the measurements were perfect — I actually assume at least +/- 1 degree C. — it’s possible we are observing minor natural climate variations of no significance at all.
People love to extrapolate short term trends into infinity.
People love to make predictions … and hear predictions.
Politicians love to have a boogeyman to scare voters into allowing them to seize more power and tell everyone else how to live.
The ONLY thing that has happened to the climate in the past 150 years is that it has gotten slightly better .. although our green plants would prefer 800 to 1,200 ppm CO2 for optimum growth — so lets all go to the supermarket and open every soda bottle we see to release more CO2 into the air and make our plants very happy.
What a waste of money to study the climate where there is no problem that needs solving … especially those computer gamer nerd who get good money to play climate computer games all day and tell everybody they know they are working to save the planet !

Nothing can even approach infinity. the largest known number is just as far away from infinity as 1 is from infinity in other words infinity is infinity larger than all real numbers.


Richard Greene,
“People love to extrapolate short term trends into infinity.”
This Wednesday morning at about 0900, it was 18C here.
At 1800 it was 28C – so I guess by Friday Noon, it will be about 71C.
Sorry, Friday is not infinity.

Wow! Could there be integrity still in CAGW climate scientists?

D. J. Hawkins

No. Desperate CYA maneuvers to preserve possible future grant opportunities, yes.

D.J. Hawkins writes: “No. Desperate CYA maneuvers to preserve possible future grant opportunities, yes.”
I think you have that right. The cAGW community, who have always been a politically motivated sub-population of real climate scientists, are doing some backpedaling (fierce backpedaling I think). That cohort sold their integrity for cash on the barrel years ago. We’re just seeing them do it again.


These ‘scientists’ may not have a clue about future climate, but the sure know how to monitor the wind out of Washington. When the wind shifts, you have to adjust your heading if you want to get anywhere.


Short answer, “No”
Anyone still holding to the notion of “catastrophic” warming on decadal scale (whether human or natural) is scientifically illiterate and attempting to motivate political momentum by fear.
History shows convincingly that earth’s climate is conservative (full of known physical processes like evaporation, condensation, cloud cover, precipitation, convective circulation, etc that restore normalcy), rather than prone to “tipping points” or “runaway” change.
That’s how it’s been for billions of years and that’s how it’s going to remain


Homeostasis is a wonderful thing.

Keith J

Climate restores itself after world scale calamity. Significant impactors like the K-T event excluded naturally. But the Year Without a Summer was only an 18 month major effect. Tunguska didn’t have any real climate takes more than a few ppm of carbonic anhydride to muss mother nature.

Luther Bl't

No. It is not difficult to make a man understand something if his continuing in his job depends upon understanding it.


And vice versa.

But lots of cowardice, and as D.J. Hawkins points out, desperation. From years of false science, rigged research, calumny and grant fraud.
The cracks appear. An excellent reason to review departing rats’ research first.

Javert Chip

Integrity? You mean from the guys who (probably still) want to lock skeptics up for having pointed out the “hiatus”?
Are you nuts?

Good, time to stop the crippling green policies and taxes. Figure out how the climate really works, and then let the free market and energy abundance help us to deal with any adverse effects.


“Figure out how the climate really works, and then let the free market and energy abundance help us to deal with any adverse effects.”
Nailed it!


Unfortunately for those of us who live in California, data won’t dissuade the ecoloons, Hollywood glitterati, the MSM, our political class and enough of the general population who have swallowed the Cool Aid. Afterall, we have to save the world, think of our grandchildren, etc.

ah wrong reply;p of course it won’t in general, it might for this particular scam though.

But I was told several years ago that the science was settled! I wish these “top” “scientists” would make up their minds.

I know what you mean. This settled science is so unsettling.

The science is still progressing, it’s the answers that are settled.

The science is not settled Philip. Please read this 2014 press release and try not to laugh,
“While one would expect the longwave radiation that escapes into space to decline with increasing CO2, the amount actually begins to rise.”
“The finding was a curiosity, conflicting with the basic understanding of global warming,”
“It made us think that there must be something really weird going in the models in the years after CO2 was added. We wanted to resolve the paradox that climate models show warming via enhanced shortwave radiation, not decreased longwave radiation.”
“Donohoe, along with MIT postdoc Kyle Armour and others at Washington, spent many a late night throwing out guesses as to why climate models generate this illogical finding”
Throwing out guesses?!?!?!
And, wait there’s more;
“Meanwhile, like any physical body experiencing warming, Earth sheds longwave radiation more effectively, canceling out the longwave-trapping effects of CO2.”
Ooooh, cancelling the longwave-trapping effects of CO2. Sounds interesting.
“Earth now absorbs more sunlight, tipping the scales to net warming from shortwave radiation.”
“So there are two types of radiation important to climate, and one of them gets affected by CO2, but it’s the other one that’s directly driving global warming — that’s the surprising thing,”
Meanwhile Isaac Held, senior scientist at NOAA, responds to the paper with,
“While this study does not change our understanding of the fundamentals of global warming, it is always useful to have simpler models that help us understand why our more comprehensive climate models sometimes behave in superficially counterintuitive ways”
That play down (“does not change our understanding of the fundamentals”) does not correlate with,
“conflicting with the basic understanding of global warming”,
does it!
“I think the default assumption would be to see the outgoing longwave radiation decrease as greenhouse gases rise, but that’s probably not going to happen,”
” Will we actually ever see the longwave trapping effects of CO2 in future observations? I think the answer is probably no.”
“The authors demonstrate that the source of the differences lies in the way in which a model represents changes in cloud cover with global warming, another big factor in how well Earth can reflect shortwave solar energy.”
The essence of the paper adds another mechanism in essence to the ‘power’ of the ‘enhanced greenhouse effect’ such that these two then don’t add up to a ‘hill of beans’ due to the hiatus!!
As shown by the data.
Interestingly, Isaac Held levels no direct criticism of statements quoted.
Totally amazing. All as mad as a box of frogs.

Thin Air

Here is another article (linked to PNAS article summarized in the MIT newsletter mentioned above by nuwrld), pointing out the limited effects of CO2 for warming, from way back in 2013, and largely ignored.
“On the direct impact of the CO2 concentration rise to the global warming”
Alfred Laubereau and Hristo Iglev
Published 8 November 2013 • Copyright EPLA, 2013
EPL (Europhysics Letters), Volume 104, Number 2

nuwurld observes: “Throwing out guesses?!?!?!”
OK. My turn.
CO2 doesn’t freeze the way water does, so it has no limit at the tropopause. It carries heat as it ascends past the trope, making it a more efficient mechanism.
Or, is that just too simple?

The tropopause is the bottom of a temperature inversion that runs through the stratosphere and maintained by UV absorption heating the ozone in the air.
The temperature inversion stops CO2 gas just as well as it stops N2 and O2. There isn’t much water vapor (or ice crystals), though big thunderstorms can inject water into the stratosphere in their central updraft.

I’m not sure I read that right but it looks as if Held is saying that it could be the models that are causing the global warming. Perhaps someone will give me a grant to study that angle. It’s about the only one that hasn’t been tried yet!

“I wish these “top” “scientists” would make up their minds.”
What they’ve got is “Top Men”:

I would rather they find their “minds”.
All too often, they’re real good at finding and using bias, then seeking publicity.

Isaac Held is a gentleman. He is the only blog operator who has contacted me through personal email to tell me of a comment disallowed. Further, he was willing to try to communicate and resolve.
However, Isaac Held is invested through the many papers written and an initial assumption which he tried to convey to me.
Isaac Held truly ‘believes’ that the process of diffusion homogenises temperature in a gravity field. We didn’t get much further than that. Maxwell’s distribution due to statistical analysis apparently allows diffusion to normalise gravity. This makes molecular noise the only process known to man that defies gravity. I could not accept this concession.
His belief then requires long wave opacity to produce the continuous instability that causes convection.
Whereas, data says that measured tropospheric profiles by all mechanisms feel gravity.
The MIT ‘clowns’ convey the errors unwittingly. Isaac Held is in no position to attempt to correct the shocking truth of their analysis, which is confirmed by the data.

Does this mean that we need another round of temperature adjustments? Soon, we will just be comping out of an ice age in the ’60s or ’70s…
After all, a basic tenet of science is to bend reality to fit your model…


trends estimated from a large multi-model ensemble.
they still don’t get it. the future is not an average of what might happen, no matter how large your sample.
consider a simple case. much simpler than climate forecasting. a pair of dice. if you run a computer model, you will find that your result will be somewhere between 2 and 12, with 7 as the average.
so climate science has taken 7 as its prediction for future climate. but this is nonsense, because the actual result can be between 2 and 12. and no one has the necessary math of physics to know which value the future will bring.


Climate science models are skewed toward 8 as the average by including the parameter/guess that rolling a number 7 or higher will lead to an increased likelihood of a 7 or higher on the next roll.


…when actually, the climate is n number of die, whose average is computed from every die, but some die are tossed more frequently than others. – i.e. chaos




No. As a noun for a face-numbered cube, die is singular; dice is plural.

ferd berple

so climate science has taken 7 as its prediction for future climate. but this is nonsense, because the actual result can be between 2 and 12. and no one has the necessary math of physics to know which value the future will bring.

It is worse than it, actually.
The climate industrial-academic-bureaucratic class has modeled future temperatures to be between +2 and +6, made forecasts and warnings and prepared thousands of papers on hundreds of topics predicating the harm that will happen as if EVERY future climate will be +10 to +14, ignored the real-world trends that forecast an actual future temperature between -2 and +4, and ignored the 100% guaranteed harm for 100 years that will result in trying to artificially limit CO2 increases to values that WILL NOT CHANGE THE FUTURE TEMPERATURES by any more than 0.05 degrees!



john harmsworth

Well done, all of you! Pretty much described the whole of AGW pseudo-science there very succinctly!

Tim Hammond

It’s worse, as the ensemble showed between 2 and 12 and it ended up being 1!

Modern climate science has not taken a “7” as it’s prediction of the future !
Maybe some real climate scientists did but not the hotshots at NASA – GISS and NOAA
They threw two dice and came up with a “13” as their prediction of the future!
Runaway global warming that will end all life on earth. — that’s a “13”
Modern climate “science” starts with the “known” prediction of the future and works backwards.
The future climate is known with great certainty.
Past historical temperature data constantly “changes” to support the prediction.
In fact, monthly average temperature should be put in a drawer and ignored for the next 10 to 20 years until the numbers get the proper “adjustments” and settle down.
The life will end prediction never changes, although the date of doom is continuously pushed forward .
There is no time to debate the prediction because scientists are working 25 hours a day to save the Earth .. and besides 97% of scientists agree and the other 3% were hard of hearing and didn’t hear the question.
Modern climate “science” is like a comedy movie … except it’s real

Moderately Cross of East Anglia

So the scientifically responsible and correct moral choice would be to teach students that the climate is not, as per their previous assertions, behaving in step with the predictions of dangerous and unprecedented warming then, wouldn’t it?
Any chance of that happening? No, I thought not. But never mind, there isn’t any possibility of the BBC, Guardian or New York Times telling their audiences about how a major part of the alarmist fantasy just fell apart.


Add CBC to that list. CBC seems to have an official policy to never question the CAGW official narrative. Anna Maria “Spumante’s” (all the bubbles, none of the substance) self delusion is remarkably on display for the whole country to listen to in painful embarrassment.


Yep. Did you catch the CBC Vancouver’s latest fairy tale [podcast] Vancouver 2050, complete with 50% more extreme hot weather days by 2030, a ban on internal combustion engins and hydrogen fuelled driverless cars zooming about town….
Taxpayer funded delusion – and eco charlatan Suzuki @ 80 still on staff as a science consultant.


In this case driverless cars means they are stationary since Hydrogen is not likely to become a transportation fuel of the future w/o using natural gas to produce the hydrogen as is the current situation. I have worked on many Hydrogen plants and they all use natural gas as a feedstock and dump the carbon into the air as CO 2. The alternative of making H2 from water needs a lot of energy and not likely viable on a large scale either.
Has anyone seen this from tallbloke on electric cars?

Crispin in Waterloo but really in Toronto

The CBC finds the most ill-informed, obtuse argument-presenting interviewees imaginable. Some are beyond even my fertile imagination. Ms Tremonte’s slavish kow-towing is really hard on the logic centres. The howlers that come from the WWF rep are legion. Every bit of claptrap rattling out of the alarming grab-bag is accepted at face value at the CBC. Even being told by an NGO head that they were being paid $17,000 a week in American money to disrupt the BC pipelines didn’t faze her. Foreign bribery? Good for business!
I cannot imagine the news of the pause will reach them.


Good old “A million horrible ways to die Suzuki”. In a recent (CBC) interview he took great pains to explain how his (self appointed?) status as an elder gave him license to be an even ruder jerk than he has been all his life. It seems that he understands the concept of being an elder even less than he understands global warming (which is to say virtually not at all).

I’m no scientist, certainly not a politician, nor even a journalist, just a concerned member of the public, but long enough in tooth to see what’s going on here.
Over several months there appears to be more than just the usual dribble of sceptical science published globally. In fact it’s becoming, if not yet a tsunami, at least a little wave.
We sceptics have known about the hiatus for a number of years, and also the incredible disparity between observed temperatures and forecasts.
But Trump has changed the political landscape and when the IPCC are forced to revise their ludicrous predictions down, again, they will be, at best, ridiculed. And that is likely to coincide neatly with Trumps run for a second term and, possibly, a UK general election.
There will be innumerable ambitious politicians, keen to make a name for themselves by saving both the UK and the US tens of billions of £/$’s by condemning fake climate science, the demolition of which, will be well under way by then.
Someone caught their jumper on the barbed wire, and as fast as they run, the jumper is unravelling.
Happy days!

Happy thought but I’m not so sure that can even happen. All of the once august scientific institutions have backed this to the hilt. Each and every last one of them. All of the once prestigious journals have done the same. All of the erstwhile great universities. All of the Western politicians have nailed their colours to the CAGW mast. Virtually the entirety of the mainstream media – with one or two notable honest individual ‘rogue’ journalist exceptions such as Dellingpole and Booker. And this is why people who have either never looked in any kind of depth or are unable to do so simply cannot believe that the whole thing could possibly be a giant steaming wobbling pile of bovid ordure from start to finish.
The politicians being the slimy gits they are of course may well attempt to slither out of it – and scapegoat Obama for example – but surely the rest of those mentioned have no way back out of this whatsoever. All they can realistically do is to ever so slowly shift the funding emphasis and dial back on the discussion of it and hope that eventually it fades out of sight like the Cheshire cat without anyone noticing too much.

“All they can realistically do is to ever so slowly shift the funding emphasis and dial back on the discussion of it and hope that eventually it fades out of sight like the Cheshire cat without anyone noticing too much.”
Eloquently put sir/madam.
Because that is precisely what they are starting to do in my opinion.
There will be a lot of spluttering and excuses, but of course they will never have actually believed in the preposterous concept of CO2 generated AGW, they were merely pointing out that the world is warming naturally.
If you look closely enough, politicians, and even scientists have little get out clauses in historic statements they will invoke when the shit hits the fan.
I mean, Tony Blair wriggled out of Iraq and became middle east peace ambassador to the UN, or some other unlikely title.
If he can manage that astonishing sleight of hand, others wriggling out of AGW support will be a doddle.
Pity is, that we all let Blair and Bush off the hook.

“Someone caught their jumper on the barbed wire, and as fast as they run, the jumper is unravelling.”
Here’s my version: Auntie Beeb got her tilt caught in a wronger.

I’m in the US, if things are different in Scotland what I say could be wrong for that country:
Your predictions are ridiculously over-optimistic.
But please stay optimistic.
I wish everything you said will come true.
I’m a realist who understands the politics behind the boogeyman — currently runaway warming, but could be something else in a few years if the weather got unusually cold: Environmentalists will ALWAYS have a boogeyman and the “cure” will ALWAYS be a more powerful government
Trump changed nothing.
He and Pruitt are like scared children afraid to even suggest CO2 may not control the climate.
Trump gives the impression of knowing nothing beyond what was necessary to be a good salesman — he gives the impression he has never read a book on government, economics, climate change or practically any other subject outside of sales.
Trump and Pruitt are two losers, in my opinion.
Trump has no chance of a second term — he grossly over-promised what could be delivered in his first term.
He may not even last the first term.
You completely misunderstand liberals / leftists.
They NEVER change their minds on anything EXCEPT to move further left on a subject..
And there may never be global cooling again since leftist bureaucrats control the data collection and compilation of the average temperature — they will adjust and infill to keep the warming trend going JUST LIKE THEY HAVE BEEN DOING FOR THE PAST 17 YEARS … allowing the gap between surface temperatures to grow versus satellite data … and no one in the press ever questions that gap outside of the Wall Street Journal (once) or maybe Fox News.
Our planet has been warming since the last peak glaciation 20,000 years ago — no one knows when the warming will end — it’s possible the warming ended in the early 2000s.


I think the trends will give birth to more heat that’s been hiding in the oceans.

well, perhaps like concencus ‘climate scientists’ I’m wrong. And if they were right, none of us would be on this august forum.

Are you suggesting I’m not?
“Trump changed nothing.”
So far, in environmental terms, Trump had done at least what he promised, he and Pruitt have stuffed the EPA and told the rest of the world to stick the Paris agreement up their derriere.
If there is one thing on the planet sure to turn the heads of politically minded voters, it’s a political leader who actually does what he/she states in their manifesto. To do it within months of an election is truly unprecedented. Trump has garnered some support, I suspect, if for nothing else, being at least true to his word.
Look at Trump objectively and one thing springs to mind. He’s a fairly odious character, but he does what he promises. In the UK we too have had some questionable leaders, including our current one, few, if any have done what they say they will do, and many have been re-elected.
America is a business, a huge one, but no less a global business than China, India, Russia and, of course, our own Europe, as dysfunctional as it is.
And if, in 4 years time, Donald can present a piece of paper stating that he slashed unemployment and increased US GDP because he kicked the Paris Accord into touch, he will win by a massive landslide. The value of that single announcement cannot be understated. It was a piece of political genius because he can’t lose.
As you and I know, temperatures aren’t going to suddenly shoot up to the IPCC’s apocalyptic maximum, so whatever happens, Trump wins.
And unlike most politicians who delay the inevitable in order to make themselves popular directly following an election, the point at which popularity least matters, Trump is dealing with all the shitty stuff early so it will be but a distant memory when he waves that piece of paper in front of the cameras.
The guy may be portrayed as an oaf, but unlike the Clinton’s who had their child problems, Trump has a seemingly stable family who are all pitching in to help. Perhaps not ideal from the nepotist conspiracy theorists point of view, but what American family wouldn’t love to have the people they trust most working with them?
Within days of election he’s rattled some international cages and gauged the reaction. he now knows the lie of their land better than probably any other president in history. And whilst everyone bitches about him, the world has been screaming for years about different ways of doing politics. Trump comes along, delivers just that, and now they are screaming about his methods.
And the clincher is, Trump has stuck two fingers up at the global opposition (or an American middle digit) and said quite clearly, America’s willing and able to take you all on. The UK has said the same to Europe, and I truly hope the US and the UK will work together again, as we have more in common that the rest of the world put together.
To do that, we will have to also quietly sideline the Paris accord and the rest of the world, and Europe, will watch as the climate change edifice crumbles, quietly and gracefully. The ones left standing will be the marginalised lefty greens, and they will be back where they belong, in their CND camps on the shores of the Holy Loch campaigning against nuclear submarines.
Will Trump be re-elected? Who knows. But at his final re-election speech he only needs to say “At least I tried to deliver better politics” and he should be, assuming nothing really big goes tits up in the interim. And Kennedy was the last victim of that kind of monumental disaster.
I didn’t like the guy from day one. The best of a bad bunch. But at least he’s delivered on some of his manifesto promises, and that goes a long way with voters. It’s also made me sit up and think.

Don’t take the piss. The beginning of the end is nigh.

Hotscot, I lived in Belvedere, just down the road from where you are now and took my driving test in Dartford back in the 60s.
I have been living in Wales for the past 48 years though.

A C Osborn
Hey! bit of a coincidence really, I was a driving instructor around South London, including Belvedere, several years ago.
But you don’t want to come back here for a visit, Belvedere is much the same I suspect but Dartford is the pits. Lowfield Street, the main drag into Dartford has been boarded up for nearly 15 years. Tesco bought most of it up and after 12 years of prevarication, finally pulled out of building a supermarket, not that Dartford council helped.
Now we’re back to hoardings while we wait for new flats to be built, and the place still looks like a slum. The town centre is charity shop heaven, but then with Bluewater, and Thurrock Lakeside on our doorstep, what do we expect really. But then, the council, again, have done little to encourage traders to move in.
I’m retiring in 4 years, probably back to Scotland, assuming the mad SNP are gone, or at least had their wings clipped more than they were at the GE. If not, it might have to be Wales in which case, we can go for a pint and watch some Rugby together. :):)

I think the number is trillions if one includes the failure to find alternatives to fossil fuels and the mandatory requirements put on industry.

Rasa, it isn’t like the thermometer has been around that long. You have to give people time for this sort of thing. They need to adjust their portfolios, maybe even their underwear. It may take generations…

An encouraging development, One does wonder is there some sort of catch? Did the Russians do it or maybe those Pesky Qataris? . I do wonder why Dr Glassmans Rocket Science Journal does not get quoted more often It really is all there including Henrys Law from this In 2007. Glassman is the Author of the Glassman Algorithm a modelling pioneer in the FFT One can only marvel at the hubris of the Scientific Political Establishment on these questions.

Sorry here is Glassman’s CO2 Why Me paper, pay close attention to what he says about CO2 flux using the Wanninkhof gas exchange rate model in the beautiful Takahashi diagram. AR4, Figure 7.8, p. 523.

RE: “Santer and his co-authors say their paper is “unlikely to reconcile the divergent schools of thought regarding the causes of differences between modeled and observed warming rates.””
Let’s welcome this small acceptance of verified reality by the ‘mystic modelers’! While this admission was surely ‘unsettling’ for the purveyors of sedimentary climate science, it may reflect a first, toddling return step towards the scientific method.

Dave Fair

Please note everyone: The difference between models and observations is now a given. The climate science “sexual intellectuals” (f….ing idiots) are simply arguing among themselves about causes. They will screw up that work too.


climate models show 2.5 times more warming in the bulk atmosphere…..
How much of that is because they are tuned to past temps that have been adjusted/fudged/jiggered to show a faster rate of warming than is real?


…and speaking of hiatus….you’re supposed to be on one right now mister!

My understanding is that the models cannot either hind cast or forecast from first principles, and thus have to be endlessly “fudged” to be able to do either.
That’s fine (and not unusual in science), if people admit it. But they don;t, and continue to claim that the models work well, when the obviously do not.


While true do
code patch upon
code patch upon
code patch upon

it’s goto’s all the way down.



In programming, the goto statement was an unconditional transfer of control statement used in the early days of programming, which often lead to programs whose flow of control was hard to read, (called spaghetti code). Using goto’s in a program is highly discouraged, and it has been proven that goto’s do not add any power to a programming language that can’t be handled by the more structured if- and if-else-statements.


My understanding is that the models cannot either hind cast or forecast from first principles, and thus have to be endlessly “fudged” to be able to do either.

I’m no scientist but if the models aren’t derived directly and solely from first principals, then the notion of “it’s basic physics” is wrong.
If the models were indeed “basic physics”, then they could be validated and would produce predictions instead of projections.

Don’t the climate models assume the “positive feedback water vapor tripler”
— tripling any conservative forecast of CO2 acting alone,
leading to forecasted warming consistently far from reality ?
Do the modelers / models care about the past temperatures?
If they did, there’s no past evidence in any proxies or real time measurements
of any positive feedback, much less positive feedback tripling the warming from CO2 alone?
I think they are completely ignoring climate history.
And they’re not real models — models have to be based on a well understood process.
Climate change is far from well understood.
The so-called GCM models are fakes designed to present personal opinions with complex math which appears to be real science to laymen.
The results of the models (predictions / projections / simulations / farm animal excrement) is exactly what the modelers believed all along — they’re wild guesses of the future climate are not real science and those are not real models !

We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.
in other words, by adjusting the past, we have been feeding lies to the models and they have given us a crazy answer as a result. Big surprise. 2001 Space Odyssey showed what happens when you lie to computers.
Their answer? We need to adjust the post 2000 forcing data to match the pre 2000 adjustments. More aerosols. We need more aerosols post 2000. That’s the ticket.


exactly ferd……when they tuned…hindcast…to a faster rate of warming…..they are going to produce a faster rate of warming

Hindcast: When one snags the arse* of ones favourite fishing Breeks** with a Bloody Butcher*** one is using to fish for an elusive Burn**** trout.
*The sitting part of one’s Breeks.
**Trousers, or in American parlance, Pants (Pants are considered underwear in the UK, home of the English language).
***A traditional fly fishing ‘fly’, a favourite amongst Burn fishermen.
****A small stream in Scotland, the plural of which, is the surname of the worlds greatest poet, Rabbie, the author of the worlds greatest poem, Tam o’ Shanter.
“The poem describes the habits of Tam, a farmer who often gets drunk with his friends in a public house in the Scottish town of Ayr, and his thoughtless ways, specifically towards his wife, who is waiting at home for him, angry.
At the conclusion of one such late-night revel after a market day, Tam rides home on his horse Meg while a storm is brewing. On the way he sees the local haunted church lit up, with witches and warlocks dancing and the devil playing the bagpipes.
He is drunk, still upon his horse, just on the edge of the light, watching, amazed to see the place bedecked with many gruesome things such as gibbet irons and knives that had been used to commit murders and other macabre artefacts.
The witches danced as the music intensifies to a crescendo and, upon seeing one particularly wanton witch in a short dress, in his excitement, he loses his reason and shouts,”Weel done, Cutty Sark!” (Cutty Sark – Short Shirt).
Immediately, the lights go out, music and dancing stops, and the creatures race after Tam, with the witches leading.
Tam spurs Meg to turn and flee, driving his horse towards the River Doon, running water the creatures dare not cross.
The witch he so admired comes so close to catching Tam and Meg that they pull Meg’s tail off just as she crosses the Brig o’ Doon (Bridge over the river Doon).
Tam and Meg escaped.
We sceptics can be considered as lucky. We will escape the clutches of the witch that is AGW, but there will be a price to pay.
Of course the fastest tea clipper of her day “Cutty Sark” is on display to this day in Greenwich, London. And the witch wearing the ‘Cutty Sark’ is her bowsprit.
Rabbie Burns’ cottage is now a small museum in Ayr, and I mean small. And whilst we often bemoan our own lot, it gives an insight into real deprivation from which intellectual genius emerged. A very sobering place.
And one can, to this day, walk past the cemetery, and over the bridge crossing the river Doon where Rabbie’s poem was conceived.
And Ayrshire is the site of the Electric Brae. An uphill road where, when one lets the handbrake off in a manual (or stickshift) car, it rolls uphill.
Some say it’s an optical illusion. Personally, I think it’s witchcraft on modern day spirit levels that indicate the road actually heads downhill.
The Cutty Sarks influence is further reaching than anyone ever believed.
We sceptics know the truth.
Our AGW counterparts are still farting about with spirit levels. 🙂


I’d surmise there’s a really big lodestone somewhere under the Electric Brae, in just the right position to magnetically attract a free-rolling car up the hill. :]


The original home of the English language was from the coasts of Frisia and Saxony on the North Sea, through Schleswig-Holstein (Anglia) to Jutland. Immigrants from those parts took it with them to Britain from the 5th century AD. There it underwent evolution from exposure to Celtic and Romance languages to become the speech which immigrants from Britain carried to the New World more than 1000 years later.
American English is closer to the language of 17th century England than is modern British English, or at least than Received Pronunciation. Shakespeare did not drop final Rs (ie, was “rhotic”), as in RP (let alone in the middle of words), although neither did he “flap”, as do Americans, ie make medial T sound more like a D.
For example:
Shakespeare: water.
RP: watuh.
US: wadder.
British English is no more correct than American English. Indeed, arguably less so, just as Sardinian preserves more conservative elements of Latin than does Italian.


IF you believe in the models…then they prove that adjustments to past temps are a lie


In fact the abstract suggests there is no problem with the models (and their estimates of climate sensitivity), it was the inputs (forcings) that are wrong.
Can anyone with access to the full paper tell us the basis for the assertion in the previous sentence of the abstract from the one fred quotes: “It is also unlikely that this asymmetry is due to the combined effects of internal variability and a model error in climate sensitivity”?

“2001 Space Odyssey showed what happens when you lie to computers. ”

I wonder if these folks are reacting to the basic fact that there bread is buttered by a climate denying President.

J Mac

The citizen shareholders of the USA elected a new CEO, to ‘turn around’ a floundering US government that had been badly mismanaged by the socialist Obama administration. Accept the basic facts, RS.
While you’re at it, drop the asinine assertions like ‘climate denying’. It immediately shows your communication is both unreasonable and irrational.
Perhaps you need to take a ‘hiatus’?

Reasonable Skeptic

Sorry I triggered you 🙂 Relax, I am a total climate denier and I wear the badge proudly. I like to rub it in their faces that they call use deniers and then years after we point to problems they finally move the science to recognize the long time outstanding problem.
Look at the 2nd point of the 2nd tweet by Maue “we missed it”
Nope they ignored it. That is entirely a different thing. In fact it is anti science to have ignored it and it demonstrates that political expediency trumps (pun intended) professionalism.

J Mac

Again, “climate denier”…..
You can call yourself anything you care to but no rational observer of temporal earth ‘denies’ that climate changes, naturally. Similar to n@zi and a few other despicable appellations, using the term in association with anyone else tar brushes them and exhibits irrational behavior by you. If you intend sarcasm, add ‘ /s ‘ to the end of your sentence. Better yet, just ‘give it a rest!’

paul courtney

They are pretty well-practiced at ignoring reality thus far, they can ignore the pres. too (unless marching against him). Really, RS, do you suppose heroic scientists saving the planet worry about base things like bread ‘n butter? You sound just like a science deni0r.

Richard M

When did the president deny there is a climate?


He prefers to call it “weather” (hence he’s denying climate… ☺)


Everyone knows the climate changes. Including Trump.
Noone, including Trump, and Trump’s critics, can prove humans have anything to do with causing the climate to change. Climate change was natural in the past, and until someone proves otherwise, it is still natural in the present.


Climate accord denier . . ; )


“their” bread is buttered but why call him a climate denying President?
You seem a little hurt.


So, what does this mean?
” We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.”
Does it mean the forcing due to CO2 was not as big as they thought?
CO2 forcing was not meeting the 20th century projections?


The way I read it is this. If you go by CO2 forcing alone, you get 1 degree Celsius warming per CO2 doubling. But in calibrating the models, that wasn’t enough to account for the actual temperature increase. They assumed CO2 was the cause of most of the warming (very little natural warming – how they can separate the two, I don’t know), so some kind of positive feedback was plugged in to get the models temperatures to line up with the CO2. Then comes the actual forecasting using the models, and the whole thing falls apart. They are learning what Einstein called his biggest blunder, the use of a fudge factor to get an equation to work. As the POTUS would say, SAD!

Thin Air

It will be fascinating to see out the Main Stream Media “digests” this. Or “regurgitates” it.

Steamboat McGoo

Thin Air – The MSM will take the path they have taken so very often:
They’ll simply ignore it.


“They’ll simply ignore it.”
That’s right. The partisan problem with the MSM is not only that they tell half-truths and lies, but they also refuse to tell the truth by remaining silent on a subject, when it suits their ideology. Lies of commission and lies of omission. Propaganda 101.

I don’t think so. The MSM will jump on any passing bandwagon.
Journalist’s come and journalist’s go. Some will shuffle off to other media, some will be sacked, some will die, some will cry, “that’s not what I meant”.
And the circus will move on.
The public will remain none the wiser.

I think it may be a sea change sort of thing.
The MSM sells advertising and controversy sells newspapers. It could well be the cAGW headline is sold out, dying on the vine. If so, we can expect a rapid reversal of position, which will continue an animated controversy for another five or ten years, selling papers and making them rich (or is it “itch”?).
Anyway, I wouldn’t be so sure the MSM really has a dog in this fight.

This paper
points out, on reevaluation of the Pinatubo volcanism in 1991, what revisions to sensitivities in the climate models should be considered. Basically points out a possible factor of 2 error….of course labelled a denier paper by those who aren’t good at calculations….but published and peer reviewed….

The probability that multi-decadal internal variability fully explains the asymmetry between the late twentieth and early twenty-first century results is low (between zero and about 9%). It is also unlikely that this asymmetry is due to the combined effects of internal variability and a model error in climate sensitivity.
these numbers establish that there is between 91-100% probability the asymmetry COULD be a result of “a model error in climate sensitivity”.

Tom Halla

This could get very interesting. It sorta, kinda, looks like a retraction of their previous handwaving on temperature in the real world v. GCM projections. It could be the case that they realize that their funding source is not buying their excuses, unlike the previous administration.

The knives are out. Scrabbling for their jobs.
AGW isn’t sacred after all.


Take a look at the last sentence of their conclusions:
“Our analysis is unlikely to reconcile divergent schools of thought
regarding the causes of dierences between modelled and observed
warming rates in the early twenty-first century. However, we have
shown that each hypothesized cause may have a unique statistical
signature. These signatures should be exploited in improving
understanding. Although scientific discussion about the causes of
short-term dierences between modelled and observed warming
rates is likely to continue19, this discussion does not cast doubt on
the reality of long-term anthropogenic warming.”

Does this man have the first clue as to what the purpose of a conclusion in a scientific paper is supposed to be and what the meaning of ‘non sequitur’ is? Can’t access the full paper but how do you go from establishing that the models are currently useless as predictors of anything – when all of the predictions of AGW are based on those models – and finish your conclusion with the statement that none of the above casts any doubt on “the reality of long-term anthropogenic warming”.
That right there is crazy talk but I suppose poor Ben had no choice but to once again make with the little clown dance or otherwise he was in an express elevator to Den1er Hell – going down!


He simply had to save the money!
Last sentence of the article was certainly not going to be included in the Abstract or any press release.
So much for peer review.

Roger Knights

“this discussion does not cast doubt on the reality of long-term anthropogenic warming.”
So a warming of 1 degree by 2100 would qualify. That’s a slick diversion. The “consensus” (grin) skeptical case hasn’t been a denial of a 1-degree-by-2100 warming trend due to CO2, but a denial of a higher, dangerous degree of warming.

Dave Fair

According to the climate science soothsayers, “anthropogenic” warming has been extant only for the period of approximately 1975 to 2000. [You could even give them the post-1950 period, if you throw in wild guesses about aerosols.] Nothing certainly before that; and nothing in the 21st Century, almost two decades, during which time CO2 levels increased dramatically.
Show me a study that actually shows “… the reality of long-term anthropogenic warming.” “Long-term” would imply 75 to 100 years?

Here is the problem. Climate sensitivity is going down over time. By 2025 or so it will be zero, and going negative shortly afterwards. The more CO2 we add, the colder it will get. This is consistent with paleo history. Temperatures start dropping when CO2 levels are high, and they start increasing when CO2 levels are low. image

Does the decline in sensitivity estimates with time demonstrate reduced sensitivity or more refined understanding?
One could conclude from the cores that temperature leads the way up, and CO2 the way down…but at a ~40yr residence time, why the huge overshoot on the way down?


Climate sensitivity is likely a small, negative number (-0.5). It is the ONLY explanation for the hiatus that makes sense. In fact you can perfectly replicate observations using this assumption.

It’s the only explanation for the long term stability of the climate also. Any significant +ve number would spell actual catastrophe in a very short time unless I have something badly skewed here.


It’s also apt that ECS and TCS should approach equality.

Ferdperple sez:
“Climate sensitivity is going down over time.”
That’s your speculation with no scientific proof.
Your chart is meaningless nonsense — it does not support that conclusion.
” By 2025 or so it will be zero, and going negative shortly afterwards. ”
That’s your speculation with no scientific proof
“The more CO2 we add, the colder it will get.”
That’s your wild speculation with no evidence at all.
“This is consistent with paleo history.”
No it is not consistent.
The proxies with enough resolution are ice cores and they clearly show temperature changes lead CO2 level changes by hundreds of years. There are dozens of studies with that conclusion.
History shows the colder it gets the more CO2 oceans absorb with a lag
and the warmer it gets the more CO2 oceans release with a lag.
“Temperatures start dropping when CO2 levels are high,
and they start increasing when CO2 levels are low.”
More speculation that there is some natural control of CO2 levels..
High and low are also imprecise terms.
In general CO2 levels have been declining for billions of years
and may have reached an all-time low 20,0000 years ago.
No one knows for sure why temperatures changed
or if the cause(s) of the temperature changes
had anything to do with CO2 levels.
The evidence points to CO2 levels resulting from temperature changes.
Your comment is one speculation after another.
That’s not real science.
That’s wild guessing.


Mr. Greene – I think you missed the inference that forms the core of his first few statements. ferdberple is not claiming that ‘actual climate sensitivity’ is going down over time, he is pointing out that the published estimates for climate sensitivity are going down over time, and his chart shows that quite clearly.

To ferdpurple:
After posting my comment, I now feel your post was intended as a joke.
And I’ve been had like it was April Fool’s Day
If intended as a joke to mock climate science, then it was a great joke — I had no idea you were a secret jokester, as your posts are typically quite serious and scientific.
You showed a very short 15 year trend, from about 2001 to 2013, and extrapolated it to 2025.
That’s just like modern climate “science” — look back at the past, especially the past decade, and extrapolate that “trend” 100 years into the future.
In the early 2000’s a scientist/CO2 is evil believer would look back at the past ten years and see a lot of warming, so he would tend to predict a lot of warming from CO2 in the future.
In the late 2000’s a scientist/CO2 is evil believer would look back at the past ten years and see almost no warming, so he would tend to predict much less warming from CO2 in the future.
It’s all nonsense, of course.
Look back at the past ten years.
Blame any warming on CO2 with no proof CO2 caused any of the warming
Then extrapolate the past ten years 100 years into the future.

Climate modelling at this early stage in the study of our planet’s climate, is like modelling quantum physics with one box of Lego. Using the analogy our climate is a 10000 piece puzzle, we are aware of about 10 pieces, but not their interactions with each other or the time scales, all of which are extremely complex and chaotic to an extent. We won’t understand the planet’s climate systems or drivers for centuries, not decades. Discussing climate models is meaningless. Predicting climate changes utterly impossible. I wish attention and discussion would turn to studying the many variables in the climate systems, like the oceans, the sun, the clouds, cosmic effects, and the dozens of other variables.

“modelling quantum physics with one box of Lego”
Fantastic analogy.

Gary Pearse

Holly, you are assuming they are honest in their work. This has long been debunked. Sceptics have been tell these guys about the hiatus for over a decade. They’ve been telling them about oceanic oscillations and natural variability for decades. CliSci warmistst have been insulting us on this until today. You upgrade their chicanery greatly by mentioning quantum physics on this page. Manure is their subject.

You seem like smart guy, so could you answer me this here question: I want to know when I sell my house and head for the hills to build a new house that will avoid the flooding from runaway global warming, how high should the hill be?


These folks are just catching up with James Hansen. link
The CAGW position is becoming untenable and the alarmists are looking for excuses.


Ah, great, pass the ammo. My friends and acquaintances know not to poke this bear about CAGW. I’m steadfast that until the models mirror observations that I’ll be calling bullsh*t whenever the subject comes up. So happy!

even these guys don’t get it {yet}
there is no global warming anymore; the satellites are wrong even to show warming.
I think this could have something to do with what it spewed from the sun, due to the reduced solar magnetic field strength: no probe in space can withstand it without detoriation/
My data sets from my own investigations show that it has started cooling
though you may consider it not much….
Concerned to show that man made warming (AGW ) is correct and indeed happening, I thought that here [in Pretoria, South Africa} I could easily prove that. Namely the logic following from AGW theory is that more CO2 would trap heat on earth, hence we should find minimum temperature (T) rising pushing up the mean T. Here, in the winter months, we hardly have any rain but we have many people burning fossil fuels to keep warm at night. On any particular cold winter’s day that results in the town area being covered with a greyish layer of air, viewable on a high hill outside town in the early morning.
I figured that as the population increased over the past 40 years, the results of my analysis of the data [of a Pretoria weather station] must show minimum T rising, particularly in the winter months. Much to my surprise I found that the opposite was happening: minimum T here was falling, any month….I first thought that somebody must have made a mistake: the extra CO2 was cooling the atmosphere, ‘not warming it. As a chemist, that made sense to me as I knew that whilst there were absorptions of CO2 in the area of the spectrum where earth emits, there are also the areas of absorption in the 1-2 um and the 4-5 um range where the sun emits. Not convinced either way by my deliberations and discussions as on a number of websites, I first looked at a number of weather stations around me, to give me an indication of what was happening:comment image
The results puzzled me even more. Somebody [God/Nature] was throwing a ball at me…..The speed of cooling followed a certain pattern, best described by a quadratic function.
I carefully looked at my earth globe and decided on a particular sampling procedure to find out what, if any, the global result would be. Here is my final result on that:comment image
Hence, looking at my final Rsquare on that, I figured out that there is no AGW, at least not measurable

“I figured out that there is no AGW, at least not measurable”
Welcome to the club. Temps go up and temps go down, but CO2 is not the cause.

You probably just forgot to make adjustments.

um… you do realize that with 4 data points and one point if inflection (change in sign of the slope) you can always fit a second order polynomial perfectly, right?

Lets *just* get a load of this…

Because observations and coupled model simulations do not have the same phasing of natural internal variability, such decadal differences in simulated and observed warming rates invariably occur.

Q. What is a ‘coupled’ model? What’s it coupled to?
A. Garbage words
Q. ‘natural internal variability’ Since when did anything ‘natural’ happen inside a computer?
A. More garbage
Q. ‘simulations do not have the same phasing’ Does this mean things are cyclical? Cyclical things have ‘phase’ But wait, isn’t climate a ‘coupled non-linear’ blah blah
A. and am sorry people, but sine/cosines actually are linear. Non linear means singularities & chaos and chaos, does *not* by definition, have cycles.
Even if there were cycles in this supposedly non-linear climate, why is it impossible to match the phases? Its just a computer. Have they lost control of their own machines? What is wrong with these people?
Its just complete garbage.
And Michael Mann commented did he? More catty and childish snarkery I presume.
Actually makes a sort of sense. They are just a bunch of kids playing computer games and when they lose, come up with a flood of impenetrable garbage to try disguise their failings.
Its actually sad to the power of n because they themselves programmed to game. How *could* they possibly lose – unless they were totally clueless from the outset?
And they are, CO2 does not drive weather or climate or temperature or anything really.

” … CO2 does not drive weather or climate or temperature or anything really.”

“Q. What is a ‘coupled’ model? What’s it coupled to?
A. Garbage words”
No not at all. Coupled field models are where you are modeling different parameters which interact with each other and that’s all it means. For example you can have an electromagnetic field input and the EM field input causes temperatures to change and that in turn causes fluid flows to change and so on and so forth. This would be a three field coupled model with electromagnetic, thermodynamical and fluid mechanical coupled fields. Takes a lot of processing power for these kind of things and any who run such models in the real world where you have to get accurate repeatable results know that the chance of doing it successfully with a planetary climate are zero to a very large number of decimal places and those who claim to be able to do it are delusional beyond all sanity.


“why is it impossible to match the phases?” The cycles are not regular cycles so they can’t predict in advance when there will be ENSO events or how the PDO and AMO will evolve.


STRIKE ONE: No Hot spot in the troposphere of the tropics as the physics behind the models demands.
STRIKE TWO: Demonstrated lack of skill in the models to forecast atmospheric temperatures
STRIKE THREE: Demonstrated failure to predict the now agreed on existence of the hiatus in atmospheric warming
STRIKE FOUR: Greenland Ice sheet running at near record mass balance which is directly opposite of what was predicted.
STRIKE FIVE: Sea level rise rate generally remains consistent with data recorded in pre-industrial times.
STRIKE SIX: Reports on the impending demise of Arctic Sea Ice have been greatly exaggerated.
STRIKE SEVEN: Increases in severe weather and climatic events have failed to materialize as predicted. IE: there is no permanent drought in Texas or California and in fact for the first time in memory the Palmer drought index map for the US shows no “Extreme” drought anywhere and only the SW corner of ND and the very southern tip of Texas are indicated to have “severe” drought.
STRIKE EIGHT: World wide crop production has continued to increase setting new records for several years running contrary to the claims that “climate change” would cause markedly reduced production.
I’m sure plenty of others to add to the list.

Great list. Thanks for that comment.

John F. Hultquist

… markedly reduced production.
Just a point of clarification: There seems to be some confusion of “rate of increase in yield” versus actual yield or production. I can believe a decrease in the “rate of increase” of yield per area. Crop harvested is a totally different matter.
The “yield” issue is about agricultural science.
Production is about economics.
[I recall Willis E. posting about these issues.]


Ummh.. You only get three strikes. Thought you should know.


If that were true the scam would be dead. It’s not. It’s “T” ball and they still can’t hit the ball.

South River Independent

Takes 9 strikes to retire the side.


CO2 doesn’t block energy from the sun.

Only eight strikes?
How about the complete lack of evidence that anything abnormal has happened to our climate in the past 150 years … other than getting better … and better … and better?
How about the complete lack of evidence of any positive feedback(s) tripling the warming claimed to happen from CO2 alone = never seen in any climate proxies, or in the real time measurements since 1850?
How about a complete lack of evidence to make the claim that natural climate change suddenly ended in 1975, after 4.5 billion years, and CO2 suddenly took over as the climate controller in 1975?

Joel Snider

So, if the ‘hiatus’ existed after all, are skeptics still reprobates for saying so at the time?
Kind of ‘tree falling in the woods’ question.


The answer will probably be along the lines of skeptics being “right for the wrong reasons”, and still reprobates. 😐

Joel Snider

You’re probably right – a perfect act of self-serving, retro-rationalization.

JB Say

Haha: “systematic deficiencies”
Its like getting Fonzie to admit he was wrong.


i was wro, wrr, wroosh, wron (almost got it there), wrrrggg…

Not “systematic” but “systemic”. Which means they don’t know any better.


Should have also noted Karl paper (early ‘draft’) that was released to goose the Obama-Paris political machine has been roundly debunked by even those on the sky-is-falling crowd.

Bruce Cobb

But,but,but, isn’t the missing heat hiding in the oceans, just biding its time? It’s the boogeyheat!

Rick C PE

Well I think it’s obvious that the authors must be secretly accepting funding from the fossil fuel industry. Maybe understandable as it seems likely their US taxpayer funding will be substantially cut. Need to check to see if they’ve been added to the list of “den1er$”.

Michael Jankowski

Shocked Mosh hasn’t appeared to note that RSS’ calcs use a model.

I’m waiting for his latest explanation of why the climate status quo is always right.


Not. Tired. Of. Winning.

michael hart

There was a time when even most of the fake stream media were quite happy using the term “lukewarmer”, indicating that they are mostly quite capable of understanding the concept. It would be an interesting study in itself to ask why so many of them then decided to favor the D-word, when the facts are falling entirely on the side of the lukewarmers.

Griff? Griff? Where are you, Griff, with your usual copy and paste quotations from “peer-reviewed” publications? Griff?

Don Perry
Awwww…..Don’t be mean to Griff. At least he tests sceptical science. And loses, admittedly, as does Mosher.
There’s a hymn about that: “Oh come all ye faithful”.


Be kind. No gloating. They have to have time to mourn. And, figure out the next bogus crisis requiring more govt control of our lives.

Mark L Gilbert

Looks like Water Shortage is the next mule LOL

Javert Chip

Griff is out counting polar bears and trying to beat up women…

That tears it. We are all going to die.

“97% of all climate scientists who express an opinion about the hiatus in abstracts of their reports believe the hiatus is real”
or something like that.

Temperature within the current ice age varies by 13C. You’ll never prove any effect of anything on it.

Jeffrey Mitchell

My concern about this paper is this: the news cycle presents its conclusions and then moves on. What remains for fact checking are Wikipedia’s biased articles which still claim there is no pause, and that the hockey stick is still good science. That is if I understood the articles correctly. Here they are:
As with any article about something politically controversial needs to be taken with a few tons of salt. It is unfortunate, but the lack of trust generated by the dishonesty spills over into less controversial areas.

I Came I Saw I Left

You could easily update Wikipedia to reflect this development (anyone can edit wikipedia). Simply reference the paper in your edit and you’ll be gold.

michael hart

Actually, many people report that you will likely find that you can’t update Wikipedia, or that any changes may be reversed.
Wikipedia certainly still has very many good pages. Probably the majority. But in some areas you may as well be trying to push water uphill. This is now a politicized topic, and Wikipedia cannot be trusted on heavily politicized topics. On ‘global-warming’ you should trust Wikipedia about as much as you might trust it when, for example, reading about Israel/Palestine politics.

I Came I Saw I Left

As long as you attribute whatever you say with a reference it falls within Wikipedia’s guidelines. Yes, someone can remove what you edit, but you can go back and remove what they did to restore your edit. If someone removes something without cause it can be contested. Somebody has to be committed to following the process through, though.

I wonder where William Connelley is these days.
He made a great gatekeeper at Wikipedia before we gave up on Wikipedia as a source of informed climate information.
I wonder what he thinks of this paper.

Wikipedia is a majority rule bogus “encyclopedia.”
The majority also tend to be young and liberal.
I once signed up to correct an article about audiophiles, based on my 40 years of experience as an audiophile.
The article was so far from reality that I went through the trouble of signing up and posting corrections.
The IPCC may be 95% certain, but I was 99% certain my corrections would have made the article better.
My corrections of some completely incorrect claims were “deleted before the ink dried”.
I tried again using very simple clear language, thinking I was not concise enough.
Again, my corrections were “deleted before the ink dried”
I never attempted to edit Wikipedia again, and that was ten years ago.
Wikipedia is majority-ruled trash.
It is fine for looking up who played “Beaver” on the “Leave it to Beaver” TV show — that’s about it.
I’ve been writing an economics newsletter since 1977 — I would NEVER trust Wikipedia for information if there was another source … and even if there was NOT another source.
When I find out a person is dishonest, I never trust them again.
I found out Wikipedia is dishonest.
They prefer a misleading article with incorrect points … with a link to a source … to an accurate article with no incorrect points from a person with 40 years of experience as the source.
And although misleading and incorrect points can be changed, at least for a few minutes, the changes will be reversed by the majority-rule mob by the next day.
I can’t imagine what Wikipedia says about climate change … nor do I care!


But, but, Phoenix is 368 degrees F, and the Mohave is hot and dry and stuff … never mind…


I take it that if the over hyped global warming manufactures (“scientists”) are now saying there is a pause then it’s actually cooling and that is a concern .The only good thing is as CO2 rises and it’s cooling the global warming fear mongering industry goes dark .
Let real science be restored to it’s rightful place .

Jeffrey Mitchell

At the moment, I think they’re finally realizing they have to give in, not that the climate is cooling. We frequently joke about the Gore Effect wherein wherever Gore is, it snows or the like. But that is weather, and it is only a joke. Your comment is a fun take though.

The real Al Gore Effect:
When Gore has a lot of face time on TV, as in the 1990s, the world gets warmer.
When Gore is nearly invisible, as he was after he lost in 2000, the warming stops.
This is conclusive proof that the primary cause global warming is Al Gore’s “hot air”
I do not expect a lot of global warming in the future because Mr. Gore is too busy spending his money at all-you-can-eat-buffets, and plans a second carer as a professional wrestler under the moniker “The Blimp

Bill Treuren

The real money in the future is not CAGW but in understanding why it did not happen. There may be less jobs but they will be the only jobs.
These folk are the smarts and will win the work in the new world order.
Court Jesters no more than that.
Even the fossil fuel industry is screaming for a carbon tax their last chance to kill the coal industry their biggest rival to gas.
Personally I am happy for the world to maintain a watching brief and maybe a modest carbon tax to encourage a migration to gas which is clearly a very capable fuel for the world that we now live in.
Principally the green industry lives in the ideological space and they work in the watermelon mode.
Lets encourage the separation of science from politics I do not like the prospect the worlds future being based around a Marxist process we have had 100 million dead in the first 100 years.

Roger Knights

“Even the fossil fuel industry is screaming for a carbon tax their last chance to kill the coal industry their biggest rival to gas.”
I suspect it’s more likely that they were pressured to do so behind the scenes, and that they worried about being boycotted or slimed if they didn’t go along with the crowd.


Oh great! Let’s all get on board with naked “Crony Capitalism” to save the planet!


I couldn’t find this important news on the BBC website, but they do have a front-page story in which it’s claimed that Global Warming will not only make coffee more expensive but poor-tasting, as well.
By the way, I came across this gem, while looking to see who was reporting this news. Whom do you suppose would repopulate the Earth after a nuclear holocaust? According to their plans, it would be the elites and their secretaries! You can’t make this stuff up!
“The wives of public officials would not be admitted to the elite hideout [nuclear shelters] but secretaries would”!%2B(2).jpg


Now that they hope it’s over, CACA cultists are willing to concede the obvious, ie that there was a plateau in global warming during all of this century before the super El Nino of 2015-16, despite rapidly rising CO2 all that time.
But will their newfound honesty permit them to recognize when the plateau returns, as earth cools off from the late SEN?

Jeffrey Mitchell

Its the Daily Mail. And yes, they do make this stuff up.
