“The gap between observations and models persists. The observed trend deviated by as much as −0.17 °C per decade from the CMIP5 (Coupled Model Intercomparison Project Phase 5; ref. 19) ensemble-mean projection1—a gap two to four times the observed trend.
The hiatus therefore continues to challenge climate science.”
– Nature Climate Change (PEER-REVIEWED STUDY)
“This paper published today in Nature Climate Change by Hedemann et al. not only confirms the existence of “the pause” in global temperature, but suggests a cause, saying “…the hiatus could also have been caused by internal variability in the top-of-atmosphere energy imbalance“.
That’s an important sentence, because it demonstrates that despite many claims to the contrary, CO2 induced forcing of the planetary temperature is not the control knob, and natural variability remains in force.”
The “pause/hiatus” in Global Warming is now nearing 20 YEARS. This despite *record* man-made CO2 emitted over the same period.
Don’t be at all surprised if – CNN, BBC, ABC, CNBC, LATimes, NYTimes, WaPo, The Age, SMH and the rest of the “climate change” obsessed sycophant media don’t report this massively inconvenient climate news. – Too many reputations, jobs, govt grants and funding are now at stake.
The “uncertainty monster” strikes again
We’ve been highly critical for some time of the paper in summer 2015 by Karl et al. that claimed “the pause” or hiatus went away once “properly adjusted” ocean surface temperature data was applied to the global surface temperature dataset. Virtually everyone in the climate skeptic community considers Karl et al. little more than a sleight of hand.
No matter, this paper published today in Nature Climate Change by Hedemann et al. not only confirms the existence of “the pause” in global temperature, but suggests a cause, saying “…the hiatus could also have been caused by internal variability in the top-of-atmosphere energy imbalance“.
That’s an important sentence, because it demonstrates that despite many claims to the contrary, CO2 induced forcing of the planetary temperature is not the control knob, and natural variability remains in force.
Also of note, see the offset as designated…

The warmist Met office’s latest hadCRUT4 data shows global temps are back down to 1997 levels, closely matching sat temps. Therefore the extremely inconvenient “Pause” or “Hiatus” can now be tracked for a period going on 20 years, despite *record* CO2 emissions over the same period. Not at all what we were promised by experts. The scam is over. The theory is bust.
The increasing rate of the global mean surface temperature was reduced from 1998 to 2013, known as the global warming hiatus, or pause.
Researchers have devoted much effort to the understanding of the cause, reports Phys.org. The proposed mechanisms include the internal variability of the coupled ocean-atmosphere system, ocean heat uptake and redistribution, and many others.
However, scientists also want to understand the atmospheric footprint of the recent warming hiatus as the dynamical and physical processes remain unclear.

“NOAA’s decision to withhold the documents was, he wrote, ‘without any justification in law’.
Last week Peter Stott, head of climate monitoring at the UK Met Office, admitted that notwithstanding the Pausebuster, it was clear ‘the slowdown hasn’t gone away’. The ‘pause’ is clearly visible in the Met Office’s ‘HadCRUT 4’ climate dataset, calculated independently of NOAA.”
Climate “science” finally being submitted to the proper scrutiny it deserves under the new administration.
TOM KARL et al – Time to handover the publics data, that you refused to under subpoena, when Obama ran your corrupt climate show!
Time “science” got its once good reputation back so we can make properly informed decisions with the publics money. The many trillions of their money spent so lavishly on “Climate Crisis Inc.”
It should be harder for NOAA to brush this off than it was when the last President was in office.
Revelations by the Mail on Sunday about how world leaders were misled over global warming by the main source of climate data have triggered a probe by the US Congress.
Republican Lamar Smith, who chairs the influential House of Representatives Committee on Science, Space and Technology, announced the inquiry last week in a letter to Benjamin Friedman, acting chief of the organisation at the heart of the MoS disclosures, the National Oceanic and Atmospheric Administration (NOAA).
He renewed demands, first made in 2015, for all internal NOAA documents and communications between staff behind a controversial scientific paper, which made a huge impact on the Paris Agreement on climate change of that year, signed by figures including David Cameron and Barack Obama.

“(NOAA) breached its own rules on scientific integrity when it published the sensational but flawed report, aimed at making the maximum possible impact on world leaders including Barack Obama and David Cameron at the UN climate conference in Paris in 2015.”
In 1960, Eisenhower foresaw the possibility of a criminal like Tom Karl of NOAA corrupting science….
“The prospect of domination of the nation’s scholars by Federal employment, project allocation, and the power of money is ever present and is gravely to be regarded.
Yet in holding scientific discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.”
– President Eisenhower 1960
“The fact that there has been no warming for the last 18 years is a massive blow to the credibility of climate science.”
2016 tied with 1998. Therefore if all things in the climate system are equal, this would suggest that climate sensitivity to CO2 is zero! Perhaps even negative considering a third of all human emissions since 1750 have been emitted over the past 18 years – with zero warming to show.
Add to this, La Niña has not even kicked in yet. A rough 2017/18 ahead for the global warming faithful.

RSS have also now released their temperature data for December, which, as with UAH, shows a big drop from the month before.
Annually, RSS co9me to the same conclusion as UAH, that 2016 was 0.02C warmer than 1998.
As Roy Spencer has pointed out, the margin of error is 0.1C, so statistically 2016 is tied with 1998 as the warmest year in the satellite record.
The fact that there has been no warming for the last 18 years is a massive blow to the credibility of climate science.
“It’s the flavor of the season: how outraged you manage to be is proof how wrong/evil your opponent is.”
“The same establishment makes a deafening racket every time there is an El Niño. In fact, climate activists actively hope for El Niño warm periods so they can hyperventilate about ‘record temperatures’ and advance their policy goals.”
Excellent post demonstrating the vicious rage emanating from climate change alarmists following the recent *record* drop in global temperatures!
As usual, the Left using the 101 tactic of – “Playing the man (Breitbart/Dellers), rather than the ball (evidence)”.
This is more evidence for mine that “Global Warming” aka “Climate Change” is the ultimate social(ist) issue that plays to many of the Left’s elitist agendas – power, control, money, virtue and misanthropy. After all, shouldn’t “Global Warming” alarmists be celebrating and cheering the *record* drop in global temps?! (albeit expected after a super El Niño).
The US House Science committee tweeted a link to a James Delingpole article on the drop in atmospheric temperatures of the Na Nina that is underway.

With the ever increasing divergence of surface temperatures from satellite ones, and the subsequent divergence of overheated climate models to observed reality, it is worth a background on atmospheric measurement systems from former NASA climate scientist Dr. Roy Spencer, Ph.D. – climatologist at the University of Alabama in Huntsville who he developed the first temperature record based on satellites…
Roy Spencer On Satellite (UAH / RSS) v Surface Temperature Data (NASA GISS) :
I claim 2014 won’t be the warmest global-average year on record.
..if for no other reason than this: thermometers cannot measure global averages — only satellites can. The satellite instruments measure nearly every cubic kilometer – hell, every cubic inch — of the lower atmosphere on a daily basis. You can travel hundreds if not thousands of kilometers without finding a thermometer nearby.
(And even if 2014 or 2015 turns out to be the warmest, this is not a cause for concern…more about that later).
The two main research groups tracking global lower-tropospheric temperatures (our UAH group, and the Remote Sensing Systems [RSS] group) show 2014 lagging significantly behind 2010 and especially 1998:
With only 3 months left in the year, there is no realistic way for 2014 to set a record in the satellite data.
Granted, the satellites are less good at sampling right near the poles, but compared to the very sparse data from the thermometer network we are in fat city coverage-wise with the satellite data.
In my opinion, though, a bigger problem than the spotty sampling of the thermometer data is the endless adjustment game applied to the thermometer data. The thermometer network is made up of a patchwork of non-research quality instruments that were never made to monitor long-term temperature changes to tenths or hundredths of a degree, and the huge data voids around the world are either ignored or in-filled with fictitious data.
Furthermore, land-based thermometers are placed where people live, and people build stuff, often replacing cooling vegetation with manmade structures that cause an artificial warming (urban heat island, UHI) effect right around the thermometer. The data adjustment processes in place cannot reliably remove the UHI effect because it can’t be distinguished from real global warming.
Satellite microwave radiometers, however, are equipped with laboratory-calibrated platinum resistance thermometers, which have demonstrated stability to thousandths of a degree over many years, and which are used to continuously calibrate the satellite instruments once every 8 seconds. The satellite measurements still have residual calibration effects that must be adjusted for, but these are usually on the order of hundredths of a degree, rather than tenths or whole degrees in the case of ground-based thermometers.
And, it is of continuing amusement to us that the global warming skeptic community now tracks the RSS satellite product rather than our UAH dataset. RSS was originally supposed to provide a quality check on our product (a worthy and necessary goal) and was heralded by the global warming alarmist community. But since RSS shows a slight cooling trend since the 1998 super El Nino, and the UAH dataset doesn’t, it is more referenced by the skeptic community now. Too funny.
In the meantime, the alarmists will continue to use the outdated, spotty, and heavily-massaged thermometer data to support their case. For a group that trumpets the high-tech climate modeling effort used to guide energy policy — models which have failed to forecast (or even hindcast!) the lack of warming in recent years — they sure do cling bitterly to whatever will support their case.
As British economist Ronald Coase once said, “If you torture the data long enough, it will confess to anything.”
So, why are the surface thermometer data used to the exclusion of our best technology — satellites — when tracking global temperatures? Because they better support the narrative of a dangerously warming planet.
Except, as the public can tell, the changes in global temperature aren’t even on their radar screen (sorry for the metaphor).
2015 “Hottest Year Ever” Update :

The Christmas pantomime here in Paris is well int0 its two-week run. The Druids who had hoped that their gibbering incantations might begin to shorten the Pause during the United Necromancers’ pre-solstice prayer-group have been disappointed. Gaia has not heeded them. She continues to show no sign of the “fever” long promised by the Prophet Gore. The robust Pause continues to resist the gathering el Niño. It remains at last month’s record-setting 18 years 9 months (Fig. 1).
Figure 1. The least-squares linear-regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset continues to show no global warming for 18 years 9 months since February 1997, though one-third of all anthropogenic forcings have occurred during the period of the Pause.
The modelers ought to be surprised by the persistence of the Pause. NOAA, with rare honesty, said in its 2008 State of…
