NEW STUDY: Global Warming “Pause” Confirmed, Climate Models Wrong

Scafetta et al.png

FOLLOWING on from the landmark paper by warmist scientists in Nature Geoscience that concedes the world has not warmed as predicted this century, comes a new paper from Scafetta et al, confirming that the global warming “pause” or “hiatus” indeed lives on!

via GWPF :


The period from 2000 to 2016 shows a modest warming trend that the advocates of the anthropogenic global warming theory have labeled as the “pause” or “hiatus.” These labels were chosen to indicate that the observed temperature standstill period results from an unforced internal fluctuation of the climate (e.g. by heat uptake of the deep ocean) that the computer climate models are claimed to occasionally reproduce without contradicting the anthropogenic global warming theory (AGWT) paradigm. In part 1 of this work, it was shown that the statistical analysis rejects such labels with a 95% confidence because the standstill period has lasted more than the 15 year period limit provided by the AGWT advocates themselves. Anyhow, the strong warming peak observed in 2015-2016, the “hottest year on record,” gave the impression that the temperature standstill stopped in 2014. Herein, the authors show that such a temperature peak is unrelated to anthropogenic forcing: it simply emerged from the natural fast fluctuations of the climate associated to the El Niño–Southern Oscillation (ENSO) phenomenon. By removing the ENSO signature, the authors show that the temperature trend from 2000 to 2016 clearly diverges from the general circulation model (GCM) simulations. Thus, the GCMs models used to support the AGWT are very likely flawed. By contrast, the semi-empirical climate models proposed in 2011 and 2013 by Scafetta, which are based on a specific set of natural climatic oscillations believed to be astronomically induced plus a significantly reduced anthropogenic contribution, agree far better with the latest observations.


As explained in part 1 of this study [1], in the last decade future climate scenarios have been used to develop and politically enforce energy expensive policies to contrast catastrophic climate warming expectations for the 21st century. This has been done mostly by the United Nations Intergovernmental Panel on Climate Change [2, 3, 4]. Several studies based on general circulation model (GCM) simulations of the Earth’s climate concluded that the 20th century climate warming and its future development depend almost completely on anthropogenic activities. Humans have been responsible of emitting in the atmosphere large amount of greenhouse gases (GHG) such as CO2 throughout the combustion of fossil fuels. This paradigm is known as the Anthropogenic Global Warming Theory (AGWT).

However, before trusting GCM projections about future climatic changes, it is necessary to validate these models by testing whether they are able to properly reconstruct past climate changes. In Ref. [1], the authors have argued that since 2001 AGWT was actually supported by the belief that the “hockey stick” proxy temperature reconstructions, which claim that an unprecedented warming occurred since 1900 in the Northern Hemisphere, were reliable [2,5] and could be considered an indirect validation of the available climate models supporting the AGWT [6]. However, since 2005 novel proxy temperature reconstructions questioned the reliability of such hockey stick trends by demonstrating the existence of a large millennial climatic oscillation [7-10]. This natural climatic variability is confirmed by historical inferences [11] and by climate proxy reconstructions spanning the entire Holocene [12, 13]. A millennial climatic oscillation would suggest that a significant percentage of the warming observed since 1850 could simply be a recovery from the Little Ice Age of the 14th – 18th centuries and that throughout the 20th century the climate naturally returned to a warm phase as it happened during the Roman and the Medieval warm periods [9, 11, 14- 16].

To test the reliability of the Coupled Model Intercomparison Project Phase 5 (CMIP5) GCMs, in Ref. [1] it was shown that for the period 1860-2016 they predict an excessive warming relative to four independent global surface temperature reconstructions. This was a first significant discrepancy between observations and models. Then, it was noted that AGWT advocates had claimed that discrepancies between observation and modeled predictions could occur because of an unforced internal variability of the climate system that the same GCMs are able to predict [17].

These people were very explicit by providing the following scientific criterion to validate the models: “The simulations rule out (at the 95% level) zero trends for intervals of 15 year or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate” [18].

By using such a 15-year interval criterion, in Ref. [1] we tested the CMIP5 GCMs against the observations in the periods 1922-1941, 1980-1999 and 200-2016. The first two periods were selected because they are characterized by a strong and compatible warming rate but by very different rate of anthropogenic GHG emissions. On the contrary, the 2000- 2017 period is characterized by a very strong increase of anthropogenic GHG emissions while the temperature has been quasi stationary. Our statistical analysis [1] confirmed with a 95% confidence that the GCMs fail to properly reconstruct the temperature trends in 1922-1941 and in 2000-2017. Thus, according to the very criterion proposed by the AGWT advocates themselves, the GCMs used to support the AGWT are demonstrated to be flawed.

Herein, a detailed study of the natural climatic variability observed after 2000 in six available global temperature records versus the performance of the GCMs is carried out. We also critically analyze the year 2015-2016, which has been famed as the hottest year on record. We show that this anomaly is simply due to a strong El-Niño event that has induced a sudden increase of the global surface temperature by 0.6 oC. This event is unrelated to anthropogenic emissions. In fact, an even stronger El-Niño event occurred in 1878 when the sudden increase of the global surface temperature was 0.8 oC: see Figure 2 in Ref. [1]. Finally, for the post 2000 period we compare the predictions of the CMIP5 GCMs used by the IPCC [2013], against that of two semi-empirical models proposed a few years ago [15,19].

These models were based on a specific number of natural oscillations suggested by astronomical considerations plus an anthropogenic warming effect strongly reduced by 50% relative to the GCM predictions. We stress that the latter result is consistent with recent scientific literature findings [20] confirming that the real climate sensitivity to CO2 doubling is about half, that is between 1 oC and 2 oC, than what predicted by the GCMs supporting the AGWT, which is about 3 oC [4].

Bombshell study: Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Government Climate Data

THE emperor really has no clothes!

Earlier this week we learned Michael Mann and his fraudulent Hockey Stick have been slapped down in a Canadian court. Mann was ordered to produce the data on which his fake claim was based (as good science demands). He refused the request and Contempt of Court charges will follow!

Add EPA Pruitt’s “red team” to the mix and the house of climate cards is looking like a dangerous place to reside!

Don’t expect the Goebbels Media to utter a peep about any of this.

Watts Up With That?

Cartoon by Josh at

Guest essay by Michael Bastasch

A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and other temperature data.”

“Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever – despite current claims of record setting warming,” according to a study published June 27 by two scientists and a veteran statistician.

The peer-reviewed study tried to validate current surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to raw thermometer readings. Skeptics of man-made global warming have criticized the adjustments.

Climate scientists often apply adjustments to surface temperature thermometers to account for “biases” in the data. The new study doesn’t question the adjustments themselves but notes nearly all of them increase the warming…

Warmist Scientist Admits: Our Models Were Wrong

MORE on the shock, global warming “pause” paper from warmists Santer, Mann et al !

via PA Pundits…


UPDATE via Climatism:


MAKE NO MISTAKE. This paper is massive. It basically reaffirms what climate sceptics (“Deniers”) have been stating for years – that despite record CO2 emissions over the past 20 years, there has been NO statistically significant global warming over this period.

There is a catastrophic problem with the UN’s billion dollar CMIP5 climate models that essentially drive the $trillion global warming industry. They are grossly overheated, leading to the panic, hysteria and fake news seen daily on the topic.

Something other than CO2 must be driving the climate. And The Godfather’s of global warming doom and gloom – Ben Santer and Mikey (hockey stick) Mann et al have released this *scientific* paper supporting the sceptical notion of a lower CO2 sensitivity than perceived by the “97%”.

It is being touted in the sceptic community as “Black Monday” owing to the release day.

Surely, this paper spells the beginning of the end for the greatest and most costly scientific fraud ever perpetrated upon mankind.

By Andrew Bolt ~

Even leading alarmist Ben Santer, lead author of a paper in Nature Geoscience, now admits the world isn’t warming as predicted by global warming models. Even Michael Mann, who produced the infamous hockey stick, has put his name to this paper.

From the abstract:

In the early twenty-first century, satellite-derived tropospheric warming trends were generally smaller than trends estimated from a large multi-model ensemble.

The problem is the models on which the global warming scare is based were simply wrong:

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.

James Delingpole describes Santer’s colorful history in the climate wars since he was outed in the Climategate scandal.

New Study Confirms: The Warming ‘Pause’ Is Real And Revealing 

Tallbloke's Talkshop

GWPF Science Editor Dr David Whitehouse takes a close look at some recent developments in the long-running global temperature ‘pause’ controversy.

A new paper has been published in the Analysis section of Nature called Reconciling controversies about the ‘global warming hiatus.’ It confirms that the ‘hiatus’ or ‘pause’ is real. It is also rather revealing.

It attempts to explain the ‘Pause’ by looking into what is known about climate variability. They say that four years after the release of the IPCC AR5 report, which contained much about the ‘hiatus’ it is time to see what can be learned.

One could be a little sarcastic in saying why would Nature devote seven of its desirable pages to an event that some vehemently say never existed and maintain its existence has been disproved long ago.

Now, however, as the El Nino spike of the past few years levels off, analysing the…

Global temperatures plunge in April – “the pause” returns

It must have something to do with the new coal-fired power stations that China and India are putting online every day of the week, for the past ~10 years and many more in the pipe.
The question is, how far will temperatures further plunge by the time India brings online its planned 2,600 coal-fired power stations over the next 10 years. ?

…let alone China.

Watts Up With That?

Global temperatures have dropped 0.5° Celsius in April according to Dr. Ryan Maue. In the Northern Hemisphere they plunged a massive 1°C . As the record 2015/16 El Nino levels off, the global warming hiatus aka “the pause” is back with a vengeance. He writes:

Some good news to end April, global temperature anomaly has fallen to only +0.1°C today (snapshot) … graphic is like stock market trace

Former Obama Official: Bureaucrats Manipulate Climate Stats To Influence Policy

Surprise, surprise again…

“Press officers work with scientists within agencies like the National Oceanic Administration (NOAA) and NASA and are responsible for crafting misleading press releases on climate, he added.”

Watts Up With That?

by Chris White

A former member of the Obama administration claims Washington D.C. often uses “misleading” news releases about climate data to influence public opinion.

Former Energy Department Undersecretary Steven Koonin told The Wall Street Journal Monday that bureaucrats within former President Barack Obama’s administration spun scientific data to manipulate public opinion.

“What you saw coming out of the press releases about climate data, climate analysis, was, I’d say, misleading, sometimes just wrong,” Koonin said, referring to elements within the Obama administration he said were responsible for manipulating climate data.

He pointed to a National Climate Assessment in 2014 showing hurricane activity has increased from 1980 as an illustration of how federal agencies fudged climate data. Koonin said the NCA’s assessment was technically incorrect.

“What they forgot to tell you, and you don’t know until you read all the way into the fine print is that it actually decreased in…

7 REASONS Why Activist Orgs Like NatGeo (Sadly) Cannot Be Trusted On Anything “Climate Change”

Nat GEop.jpg

A MUST READ unemotional and clinical scientific rebuttal of National Geographic’s latest climate change hysteria and groupthink propaganda rhetoric…

Yet another example of why – sadly – mainstream media activist outlets like the once respected NatGeo cannot be trusted on anything global warming climate change.


7 part series via our friends over at Paul Homewood’s excellent site – notalotofpeopleknowthat:

1. Seven things to know about climate change–National Geographic


National Geographic has long lost any scientific credibility on climate change issues. It’s new project, “Seven things to know about climate change”, does nothing to restore it.



In fact, as their graph clearly shows, temperatures have been steadily rising the 19thC, long before CO2 emissions could have made any noticeable difference.

Why is there no mention that the Little Ice Age, culminating in the late 19thC, is known to be probably the coldest period in Earth’s history since the end of the last Ice Age?

They also mention satellite measurements, but strangely forget to state that atmospheric temperatures last year were no higher than in 1998.

2. Second Thing To Know About Climate Change–Nat Geographic

PART 2 – Colourless, odourless, trace gas and plant food – carbon dioxide (CO2) hysteria… (Climatism comment)



They fail to explain why global temperatures fell between 1940 and 1980, at the same time as CO2 emissions were rising rapidly.

They also forget to mention the role that the great ocean cycles played in 20thC warming. The post 1940 cool down coincided with the shift of both PDO and AMO to cold phase.

Similarly post 1980 warming was in large part the result of a return to warm phase for both cycles.



3. Third Thing To Know About Climate Change–Nat Geographic

PART 3 – The fake “97% consensus” revered worldwide by the likes of Barack Obama, cooked up by cartoonist and professional climate activist John Cook. Following on from the bogus Doran/Zimmerman study of 2009: (Climatism comment)



The main cause of global warming? Err, well no actually.

According to the Cook study quoted, only 65 papers found explicitly found that humans are the primary cause of recent global warming.

I make that 1.6%, not 97%.

Full details are here.

Virtually all scientists accept that man has some effect on climate, even if only through urbanisation. The Cook study is therefore pretty much worthless anyway, as the authors knew before they published it.

But the fact that only 65 papers identified humans as the primary cause is extremely damning to the supposed consensus.

If humans are actually responsible for less than half of recent warming, the whole scare story falls apart.

Prof Mike Hulme of the Tyndall Centre summed up just how meaningless Cook’s study was:

The [Cook et al.] article is poorly conceived, poorly designed and poorly executed. It obscures the complexities of the climate issue and it is a sign of the desperately poor level of public and policy debate in this country that the energy minister should cite it. It offers a similar depiction of the world into categories of ‘right’ and ‘wrong’ to that adopted in [an earlier study]: dividing publishing climate scientists into ‘believers’ and ‘non-believers’. It seems to me that these people are still living (or wishing to live) in the pre-2009 world of climate change discourse. Haven’t they noticed that public understanding of the climate issue has moved on?


4. Fourth Thing To Know About Climate Change–Nat Geographic

PART 4 – Starting your Arctic sea ice extent graph at the century maximum of 1979… (Climatism comment)



Even their graph of Arctic sea ice extent shows that the ice has stabilised since 2007. They are, of course, hoping that readers will not notice this.

They start their graph in 1979, at the end of a period when the Arctic had been getting colder for three decades.

In Climate, History and the Modern World, HH Lamb wrote (in 1982):

The cooling of the Arctic since 1950-60 has been most marked in the very same regions which experienced the strongest warming in the earlier decades of the 20thC, namely the central Arctic and northernmost parts of the two great continents remote from the world’s oceans, but also in the Norwegian-East Greenland Sea….

A greatly increased flow of the cold East Greenland Current has in several years (especially 1968 and 1969, but also 1965, 1975 and 1979) brought more Arctic sea ice to the coasts of Iceland than for fifty years. In April-May 1968 and 1969, the island was half surrounded by ice, as had not occurred since 1888.

Such sea ice years have always been dreaded in Iceland’s history because of the depression of summer temperatures and the effects on farm production….. The 1960’s also saw the abandonment of attempts at grain growing in Iceland, which had been resumed in the warmer decades of this century after a lapse of some hundreds of years…

And during the earlier decades of warming, which he mentions, we know that temperatures around the Arctic were at similar levels to today.

For instance, Nuuk in Greenland:


The warming and cooling cycles in the Arctic have nothing at all to do with global warming, but follow the Atlantic Multidecadal Oscillation, a perfectly natural event, which NOAA says has been occurring for at least the last 1000 years.


As for the Antarctic, the land ice mass there is actually growing, according to satellite altimeters.

They also mention glaciers, but do not tell their readers that glaciers worldwide grew massively between the Middle Ages and the mid 19thC, in other words during the Little Ice Age. (See here.)

They began retreating around the mid 19thC, and observations show that the rate of recession was greater then and in the early 20thC than it is now.

As glaciers melt, we are finding the remains of forests, carbon dated to the Middle Ages, as far apart as Alaska and Patagonia. Clearly glaciers are simply returning to their natural state prior to the Little Ice Age.


5. Fifth Thing To Know About Climate Change–Nat Geographic

PART 5 – The Great “Extreme Weather” Climate Change Propaganda Con

“by most metrics, extreme weather events are becoming ‘less’ extreme as CO2 increases.”

(Climatism comment)



There is no doubt that the “extreme weather lie” is one of the most fraudulent aspects of the whole climate scam.

Even the IPCC’s SREX report could not find any evidence that that extreme weather was increasing.

National Geographic’s claim is based on the above graph from Munich Re, showing the number of “global natural disasters”. But how are these defined?

Clearly every single flood, storm and so on is not counted. According to Munich Re themselves:

Taking very small events out of the equation, 750 relevant loss events [in 2016]such as earthquakes, storms, floods, droughts and heatwaves were recorded in the Munich Re NatCatSERVICE database.

So what determines a “relevant event”. The answer of course is heavily weighted to economic cost. While this may have relevance to the insurance industry, it has little bearing on climate trends.

As the European Environment Agency explained in their “Damages from weather and climate-related events” report in 2012:

  • The observed damage increase is primarily due to increases in population, economic wealth and human activities in hazard-prone areas and to better reporting.
  • It is currently difficult to determine accurately the proportion of damage costs that are attributable to climate change.

Roger Pielke Jnr, a leading expert on the cost of disasters, has repeatedly shown claims that extreme weather is getting worse to be worthless. His graph below sums the whole topic up well.

Note that it is based on Munich Re’s own database.


Of course, Munich Re have a vested interest in pretending that weather disasters are on the increase, as it allows them to push up their insurance premiums.

Despite a supposedly calamitous year for disasters, Munich Re actually made a profit of Eu2.6bn in 2016, well ahead of its target of Eu2.3bn.

Most of this profit came from the reinsurance business, which made Eu2.5bn.


6. The Sixth Thing To Know About Climate Change–Nat Geographic

PART 6 – “There are many threats facing eco systems, but a barely noticeable increase in temperature is not one of them.”



In 1982, HH Lamb wrote about how the ranges of birds and fishes had moved poleward in the first half of the 20thC.

When the Earth started cooling around 1960, this movement was reversed. All that animal and plant species are doing is returning to where they were a half a century or so ago.


HH Lamb: Climate, History and the Modern World – p264
There are many threats facing eco systems,
but a barely noticeable increase in temperature is not one of them.

7. The Seventh Thing To Know About Climate Change–Nat Geographic



It is hard to know where to start with this load of garbage!

1) If climate change was not a serious danger, would 195 countries have signed the Paris Agreement, pledging to keep the warming below 2C?

Clearly National Geographic have failed to read what actually was agreed at Paris.

For a start, the Agreement itself actually states that, under the “pledges” made, emissions will continue to rise. To meet the 2C scenario, they would need to be cut by at least half.



Secondly, the vast majority of the 195 countries, including China and India, are designated as “developing” countries. As such, the Paris Agreement places no obligation on them at all to cut emissions, as it does on developed nations.

2) Switch to renewables


They claim that we can save the planet by switching to renewable energy. Yet even their own graph shows that, although the use of renewable energy will roughly double by 2040, this will be dwarfed by the increasing use of fossil fuels.

The reason for this is very simple – the demand for cheap, reliable energy is growing fast amongst developing countries, as their economies expand and the expectations of their people for a better standard of living grow.

Renewable energy, such as wind and solar, is utterly incapable of meeting this demand.

The sort of emission cuts needed “to do something” would condemn billions of people to grinding poverty.

3) In the US, solar now employs more people than coal, oil and gas combined.

Given that solar only provides 0.4% of the US’s energy, this fatuous statement shows just how inefficient solar power really is.

BP Energy Review 2016

4) We can do something about it!

Who is this WE?

In the last decade or so, emissions have been slowly dropping in the US and EU, and now only account for 27% of global CO2.

Meanwhile, emissions in China and the rest of the world have been rocketing upwards.


BP Energy Review 2016

Even if US and EU emissions dropped to zero, it would only take global emissions back to their level in 2002, and make next to no difference to the climate.

This whole series from National Geographic has from start to finish been based on a combination of irrelevant, fake and cherry picked data.

Sadly this seems to sum up the low standards that it has now sunk to.
