THE Great Global Warming “Pause”

Stop_global_warming_sign_in_blizzard_-_February_10,_2010_blizzard.jpg

BETWEEN the start of 1997 and the end of 2014, average global surface temperature stalled. This 18-year period is known as the global warming “pause” or “hiatus” and has been the subject of much research and debate in peer-reviewed scientific journals.

THE rise in global temperatures that alarmed climate campaigners in the 1990’s had slowed so much that the trend was no longer statistically significant. This despite one-third of Man’s entire influence on climate since the Industrial Revolution occurring since February 1997.

THE pause took a pause during the 2015/16 super El Niño which was the strongest such event in recorded history and helped to make 2015 and 2016 the warmest years in the modern warm period. However, 2017 witnessed the biggest drop in global temps in recorded history, seen across most data sets, bringing temps back inline with 1997-2014 averages, rendering “the pause” alive and well, to date.

THERE has been a recent surge in media reports aiming to debunk and bury the inconvenient hiatus, not predicted by any climatologist, science agency, government body, media outlet or UN computer model.

A few of the latest attempts by the mainsteam media at re-writing climate history…

Before it was disappeared, the hiatus was central to the IPCC report.

The MWP, LIA, 1940’s spike, 1970’s global cooling – all disappeared by the climate mafia.

Sometimes settled science requires rewriting history over and over again.

CALL me a cynic, but if “global warming” is so dastardly, and an “imminent global threat”, as we’re constantly told, isn’t a near 20 year warming “pause”, “hiatus” or “slowdown” (if that works better for you) a good thing? It definitely wouldn’t appear so by how much abuse, huffing and puffing is spewed out by the climate mafia when those two words – “pause” or “hiatus” are printed or uttered. One might think that the angry voices have skin in the climate game, financially, politically and/or ideologically. Oh…wait!

AS we know, the pause has been a big embarrassment to the climate establishment, because the longer it goes on, the more it casts doubt on their climate models and their theory, and thus threatens the literal trillion dollar industry made up of grants, funds, well-paid government jobs in climate bureaucracies, rent-seekers, advocacy groups, bird-slicers (windmills) and bat-blasters (solar farms)…

A LOT of jobs, reputations and (taxpayer) funds are now at stake.

*

TO conclude, an excellent summary of the pause and what it means for our understanding of the chaotic and complex climate system by Dr David Whitehouse…

The lesson of the pause is not that the greenhouse effect doesn’t exist, but rather that the computer models, which predicted an acceleration in global warming, and on which current policy is based, have proved to be inaccurate. Nevertheless, the pause is an important event that enriches our understanding of a highly complex climate system. In the future, a long-term rise in global temperatures may resume. There is a good chance, however, that the recent super El Niño only interrupted the 1997-2014 pause. No-one knows. But if the pause were to resume or warming keeps slowing down, many of the fundamental assumptions of climate science would have to be re-assessed.

UPDATE

THE latest “pause-buster” paper that this post is based on claims that “Missing Arctic temperature data, not Mother Nature, created the seeming slowdown of global warming from 1998 to 2012, according to a new study in the journal Nature Climate Change.” – Zhang et al. …

IF that’s the case, then what for the “missing data” at the other ‘inconvenient’ pole – Antarctica – that has been cooling for the past ~40 year and gaining ice mass?

“Ice, Cloud and land Elevation Satellite (ICESat) data (2003–08) show mass gains from snow accumulation exceeded discharge losses by 82 ± 25 Gt a−1, reducing global sea-level rise by 0.23 mm a−1..” – H. Jay Zwally et al. …

PERHAPS cancel’s out the apparent “unreported” Arctic data that underpins the latest pause-buster attempt by Zhang et al.

FURTHER, a valid and worthy observation by our friends “Climate Realists” who noted on twitter:

Latest Excuse on the Pause: There was NO pause in global warming because of a lack of data in the Arctic… and yet your told the Arctic is the worst it’s ever been.. work that one out.

AND this via @SimonMaxfield8

FOR the Arctic they give a warming estimate of 0.659°C per decade. This means, without the Arctic data, the global temperature paused, i.e. only one region was contributing to global warming, and a region where it’s been estimated about half is due to natural factors.

KIRIBATI Climate Plan: More Resorts, More Tourists

LOL!

PRESIDENT Tong knows perfectly well that without the U.S. involved in the UN wealth redistribution scam, the fast and furious ‘climate cash’ ain’t gonna come!

HE’S now backtracking from the Kiribati “drowning” scenario, big time, so as not to deter potential investors to his new “5-star” resort plans! After all, who would want to invest in a ‘sinking’ island?!

I jousted with Tong/Kiribati via twitter back in 2013 during the lucrative Obama climate-cash years…

Guest essay by Eric Worrall

The President of Kiribati doesn’t want his people to be seen as climate charity cases – instead he wants investment, new tourist resorts to give his people jobs and economic opportunities, to help pay for reclaiming land from the sea like Singapore.

As climate change threatens islands, Kiribati’s president plans development

The low-lying Pacific island nation of Kiribati is one of the parts of the world most threatened by climate change and rising sea levels. Scientists say the islands could be uninhabitable within decades, and in recent years, some leaders there have begun planning for a worst-case scenario that could involve relocating the population to other countries.

However, in a video presentation to the international climate conference in Bonn, Germany, last week, the president of Kiribati appeared…

SCIENTISTS : ‘Loud Divergence Between Sea-Level Reality And Climate Change Theory’

sea_level_rise_alarmism_NYC.jpg

Experts tell us that New York City and London will be underwater in the next 50 years | Daily Mail

SEA LEVEL RISE alarmism is just one in a long line of propaganda metrics used by the climate crisis industry to promote the narrative that your CO2 emissions are causing unprecedented climate change.

OF course none of the carefully orchestrated fear-mongering is based on observed reality, rather, worst-case-scenario climate models that are designed to scare you and policy makers into belief.

THE veracity of global climate models were recently put under the microscope by a group of ‘warmist’ climate scientists who published a bombshell paper that admitted the estimates of global warming used for years to torture the world’s conscience and justify massive spending on non-carbon energy sources were, er, wrong.

IN February 2016, climate scientist Dr. John Christy presented testimony to U.S. Congress demonstrating that the UN IPCC’s CMIP5 climate models grossly exaggerate and over estimate the impact of atmospheric CO2 levels on global temperatures. Dr. Christy noted in his testimony that “models over-warm the tropical atmosphere by a factor of approximately three″.

Reality vs. Theory: Scientists Affirm ‘Recent Lack Of Any Detectable Acceleration’ In Sea Level Rise

AUSTRALIAN scientists have published a new paper in the journal Earth Systems and Environment that highlights the “loud divergence between sea level reality” and “the climate models [that] predict an accelerated sea-level rise driven by the anthropogenic CO2 emission“.

More via NoTricksZone :

THE key finding from the paper is that long-term observations from tide gauges reveal a “recent lack of any detectable acceleration in the rate of sea-level rise“. The modern rate of sea level rise acceleration – 0.002 mm/year² – is so negligible it falls well below the threshold of measurement accuracy.

The lack of a detectable global-scale sea level rise acceleration recorded in tide gauge measurements isn’t a novel finding.  In recent years, dozens of other scientists have bravely come forward to challenge “consensus” modeling that implicates anthropogenic CO2 emissions as the preeminent cause of ice sheet melt and sea level rise.

Perhaps at some point “consensus”-based climate science will jettison its focus on models and projections of perilous future climate states directly caused by anthropogenic CO2 emissions and instead embrace the observational evidence that may undermine the alarm.

Until then, we will likely need to continue learning about how many millimeters we humans raise sea levels for each kilometer we drive in our fossil-fuel-powered vehicles. Because that’s how “consensus” climate science works.

SERIOUS questions need to be asked as to how predictive models that do not observe reality can be used so un-objectively to torture the world’s conscience and justify massive spending on unreliable-energy sources, and fund a now vast industry of research grants, environment lobby firms and advisory businesses of all types.

OVERHEATED climate models also provide the basis for billions of dollars in trading climate credits, many thousands of well-paid government jobs in climate bureaucracies, and, of course, the trillion dollar green energy industry.

INCONVENIENT UPDATE

MOST mainstream media outlets will not report something that dramatically deflates their narrative. So it goes without saying that when NASA confirmed that ocean levels have actually paused, even falling for the past few years, the media couldn’t be more than silent…

Inconvenient: NASA shows global sea level…pausing, instead of rising

Via WUWT :

This is interesting. It appears that a “pause” has developed in global sea levels. For two years, since July 2015, there has been no sustained increase in global sea level, in fact, it appears to have actually fallen a bit. This graph, provided by NASA’s Global Climate Change website, tells the story:

A zoom of the area of interest, two years prior to the most recent data point.

 

The satellite derived sea level data is also available here: ftp://podaac.jpl.nasa.gov/allData/merged_alt/L2/TP_J1_OSTM/global_mean_sea_level/GMSL_TPJAOS_V4_199209_201708.txt

NASA says on that website:

Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of sea water as it warms. The first graph tracks the change in sea level since 1993 as observed by satellites.

Hmmm, I think they left something out of that description.

The other source for sea level data, at the University of Colorado, also shows a pause, though they have not yet updated their data for 2017:

What I found most interesting on the UC sea level page was this graph, showing the correlation of El Niño Southern Oscillation (ENSO) and global sea level. [Readers] may recall that in 2015, there was a massive spike of an El Niño event:

The correlation between ENSO and sea level seems strong.

Note this image from a NASA Visualization Video, which shows water piling up in the Western Pacific over the past 22 years. Wind pattern shifts are a signature of ENSO events, and they push water westward where it piles up.

Here is another projection of the same data, showing that water has been piling up in the Western Pacific:

I wonder what the rate of sea level rise would look like is we masked out El Nino events? I’m guessing it would be far, far, less than what is being claimed as “global”.

Climate Science: Put Up or Shut Up

Science Matters

That’s the theme of an article by Rowan Dean in The Courier-Mail, Australia:  Time for climate scientists to produce evidence that carbon dioxide emissions affect climate  Full text below with my bolds and images.

IT’S time for so-called climate scientists to either cough up one single, solitary shred of genuine scientific evidence that proves that the climate is being changed by mankind’s carbon dioxide emissions, or ‘fess up and admit that the whole thing is a gigantic hoax.

That’s the bottom line.

Asked at the beginning of this year for one of those “predictions for 2017”, I claimed that this would be the year the Australian public wakes up and realises they are being hoodwinked by the whole climate change/renewables scam.

I told Paul Murray’s lively late night TV show on Sky News that 2017 would be the year the climate con comes to an end. So how is my prediction…

Dr. Christy was 100% correct …

A landmark paper by warmist scientists in Nature Geoscience now concedes the world has indeed not warmed as predicted, thanks to a slowdown in the first 15 years of this century. One of its authors, Michael Grubb, professor of international energy and climate change at University College London, admits his past predictions of runaway warming were too alarmist.

“When the facts change, I change my mind. We are in a better place than I thought.”

ANOTHER author, Myles Allen, professor of geosystem science at Oxford, confessed that too many of the mathematical models used by climate scientists to predict future warming “were on the hot side” — meaning they exaggerated.

“We haven’t seen that rapid acceleration in warming after 2000 that we see in the models.”

AND yet we have spent literally trillions of dollars of other peoples’ (taxpayers) money on alarmist global warming climate change policies, schemes and rent-seeking scams (windmills, solar panels, mothballed desal plants, pink bats, carbon taxes etc) on the advice of overheated, predictive computer models that do not even observe real-world reality!?

DON’T expect an apology or your money back anytime soon. The climate juggernaut will keep digging at your hip pocket a little while longer – too much money is on the line and too many reputations are now at stake.

OTHER OBSERVATIONS

Via NOT A LOT OF PEOPLE KNOW THAT :

The pause is alive and well!

 

 

There has been a desperate attempt to divert attention away from the findings of the new paper. This article mentions a letter to the Times by the phoneys, Lords Krebs and Stern.

I have also seen a similar letter in the Mail from Myles Allen. It stated that the difference of 0.3C was really rather insignificant, and that we were still all going to die if we did mend our evil ways, only slightly later!

But the difference is actually really huge, bearing in mind that this is over a period of just 15 years, and particularly when the authors admit that emissions of CO2 have been much greater than originally assumed.

CLIMATE Alarmism Has Cost Far More Than Any Global Warming Ever Could

tim-flannery.jpeg

“So even the rain that falls isn’t actually going to fill our dams and our river systems…” Tim Flannery 2007

GLOBAL WARMING alarmists like to bully you into belief by attacking your apparent ‘overindulgent’ lifestyle, claiming that your AC, SUV, even your diet will leave a diminished planet for our “children’s, children’s, children!”. Dire forecasts always pushed out by generations so no one can keep tabs.

 

flannery rain.jpg

YET, as the Malthusians preach their favourite eco-memes from the comfort of their air-conditioned / centrally-heated, inner suburban eco-palaces, they care little about those who live on planet ‘struggle-street’, right now.

SUCH catastrophic prognostications will inevitably continue from hysterical climate pontificators, even as a landmark paper by warmist scientists in ‘Nature Geoscience’ now concedes the world has indeed not warmed as predicted, thanks to a slowdown in the first 15 years of this century. Begs the questions; who are the real science “deniers”? And, is that “science” really “settled”?

ANDREW BOLT writes an excellent piece in The Herald Sun on one of our favourite global warming climate change hysterics, Tim Flannery, whose alarmist predictions have led to radical climate policies that have cost Australian’s literally billions upon billions in green schemes and scams – virtuous offerings to the green faith that have helped to destroy Australia’s once thriving economy and ruined people’s livelihoods.

A MUST READ…

Billions wasted. Desalination plants mothballed. Power prices through the roof. Pensioners unable to pay for their heating. It’s time to count the shocking price we’ve paid for listening to global warming scaremongers like Tim Flannery.

Andrew Bolt: We’re paying for scientists’ climate of fear

AS THE panic ends, check out the shocking price we’ve paid by treating global warming scaremongers like Tim Flannery as our gurus.

Listening to these preachers cost us billions. In fact, we’re still paying the bills — just as some climate scientists are waking up to themselves and saying, “whoops”.

Haven’t you heard? It turns out the science was not settled, after all, and sceptics were right to laugh at Flannery (pictured) and his richly paid gabble of Chicken Littles.

A landmark paper by warmist scientists in Nature Geoscience now concedes the world has indeed not warmed as predicted, thanks to a slowdown in the first 15 years of this century.

That is actually not news to sceptics. Dr Roy Spencer, who runs one of the four main measurements of world temperature from the University of Alabama in Huntsville, has pointed it out for years, but most journalists ignored him. Likewise, they’ve largely ignored that the predicted climate catastrophes have not happened, either.

We have had not more cyclones but fewer; not less rain in Australia but more; not fewer polar bears but more; and not worse crops but record ones, here and overseas.

So why have we wasted a fortune to cut the emissions we now learn aren’t actually causing a warming catastrophe — or certainly not as fast as first said? Why do we have horrendously expensive and mothballed desalination plants in Brisbane, Sydney, Melbourne and Adelaide, still waiting for the drought we were told would be permanent?

Why have we also destroyed our cheap and reliable electricity system, replacing “dirty” coal-fired generators with so much dodgy wind and solar power that we now face blackouts and world-record prices?

True, it’s not all Flannery’s fault. It obviously takes more than one panic merchant to create such mayhem. But Flannery’s career should stand as a reproach to us all, particularly to hypsters who promoted him — the ABC, above all — and to the sheep who believed him.

Flannery is the mammologist who somehow emerged as our high priest of global warming, warning of Armageddon unless we repented our sins against Mother Earth. Our emissions had caused the rains to fail, he proclaimed. Perth could become the world’s first “ghost metropolis”, he warned in 2004.

Former Greens leader and environmentalist Bob Brown. Picture: Chris Kidd

“In Adelaide, Sydney and Brisbane, water supplies are so low they need desalinated water urgently, possibly in as little as 18 months,” he cried in 2007. And he topped it all that year with this: “Even the rain that falls isn’t actually going to fill our dams and our river systems.”

As I said, he wasn’t alone. Greens leader Bob Brown in 2006 agreed we faced the “spectre of permanent drought” and The Age quoted armies of alarmists, including the Bureau of Meteorology’s Bertrand Timbal: “We are just not going to have that sort of good rain again as long as the system is warming up.”

So up went the desalination plants. Then down came the laughing rain, flooding Brisbane and filling dams.

You’d think that cosmic joke would have ended Flannery’s career and the global warming scare in one great thunderclap.

But no. Flannery, made our Chief Climate Commissioner by the Gillard Labor government, still heads the Climate Council and still bobs up as an ABC presenter and honoured guest.

And he’s still at it. For instance, two years ago he exploited the category 5 Cyclone Pan that hit Vanuatu, telling the ABC: “Elements of the damage wreaked by that cyclone are being influenced quite strongly by climate change.

“Sadly we’re more likely to see them more frequently in the future.”

In fact, that very next cyclone season our Bureau of Meteorology recorded a first in its satellite records — not a single severe cyclone hit Australia, compared with 11 in 1982.

Why did we ever listen to Flannery and scaremongers like him?

See now what their panic-making has inspired — global warming schemes that have hurt us infinitely more than global warming itself.

12 New Scientific Papers: Oceans Cooling Globally As Glaciers Thicken

“Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.”

INTERESTING to see how the warmist community will spin the “science” from these latest inconvenient findings that contradict IPCC climate model predictions and the endless Hottest Year Evah PR claims.

NO doubt, Climate Crisis Inc … and the UN IPCC won’t go near it. And don’t expect to see empirical evidence of globally cooling oceans and thickening glaciers gleefully reported on CNN, BBC or ABC Australia. Any climate news that doesn’t fit the human-caused warming narrative is expressly ignored by the #FakeNews mainstream media, using their favoured and most effective propaganda weapon – confirmation bias.

12 New Papers: North Atlantic, Pacific, And Southern Oceans Are Cooling As Glaciers Thicken, Gain Mass

Holocene-Cooling-North-Atlantic-Duchez-2016.jpg

Graph Source Duchez et al., 2016

Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.

According to Dieng et al. (2017), for example, the global oceans underwent a slowdown, a pause, or even a slight cooling trend during 2003 to 2013.  This  undermines expectations from climate models which presume the increase in radiative forcing from human CO2 emissions should substantially increase ocean temperatures.

The authors indicate that the recent trends in ocean temperatures “may just reflect a 60-year natural cycle“, the AMO (Atlantic Multidecadal Oscillation), and not follow radiative forcing trends.

Dieng et al., 2017    We investigate the global mean and regional change of sea surface and land surface temperature over 2003–2013, using a large number of different data sets, and compare with changes observed over the past few decades (starting in 1950). … While confirming cooling of eastern tropical Pacific during the last decade as reported in several recent studies, our results show that the reduced rate of change of the 2003–2013 time span is a global phenomenon. GMST short-term trends since 1950 computed over successive 11-year windows with 1-year overlap show important decadal variability that highly correlates with 11-year trends of the Atlantic Multidecadal Oscillation indexThe GMST 11-year trend distribution is well fitted by a Gaussian function, confirming an unforced origin related to internal climate variability.

We evaluate the time derivative of full-depth ocean heat content to determine the planetary energy imbalance with different approaches: in situ measurements, ocean reanalysis and global sea level budget.  For 2003–2013, it amounts to 0.5 +/− 0.1 W m−2, 0.68 +/− 0.1 W m−2 and 0.65 +/− 0.1 W m−2, respectively for the three approaches.    Although the uncertainty is quite large because of considerable errors in the climate sensitivity parameter, we find no evidence of decrease in net radiative forcing in the recent years, but rather an increase compared to the previous decades.
We can note that the correlation between GMST [global mean surface temperature] trends and AMO trends is quite high. It amounts 0.88 over the whole time span. At the beginning of the record, the correlation with PDO trends is also high (equal to 0.8) but breaks down after the mid-1980s.  The GMST and AMO trends shown in Figure 6 show a low in the 1960s and high in the 1990s, suggestive of a 60-year oscillation, as reported for the global mean sea level by Chambers et al. (2012). Thus the observed temporal evolution of the GMST [global mean surface temperature] trends may just reflect a 60-year natural cycle driven by the AMO.

Global-Ocean-AMO-Temperature-Correlation-1950-to-2014-Dieng-2017.jpg

Subpolar North Atlantic Cooling Rapidly Since 2005

According to Piecuch et al. (2017) there has been no net warming of the North Atlantic Ocean in the last quarter century.  The warming that occurred in the 10 years from 1994-2004 has been completely negated by an even more pronounced cooling trend since 2005.   The predominant (87%) cause of the warming was determined to be of the same natural (non-anthropogenic) origin as the subsequent cooling: advection, the movement/circulation of heat via internal processes.   In fact, human CO2 emissions are never mentioned as even contributing to the the 1994-2004 warming.

Piecuch et al., 2017    The subpolar North Atlantic (SPNA) is subject to strong decadal variability, with implications for surface climate and its predictability. In 2004–2005, SPNA decadal upper ocean and sea-surface temperature trends reversed from warming during 1994–2004 to cooling over 2005–2015. … Over the last two decades, the SPNA has undergone a pronounced climate shift. Decadal OHC and SST trends reversed sign around 2004–2005, with a strong warming seen during 1994–2004 and marked cooling observed over 2005–2015. These trend reversals were pronounced (> 0.1 °C yr−1 in magnitude) in the northeastern North Atlantic (south and west of Iceland) and in the Labrador Sea. … To identify basic processes controlling SPNA thermal variations, we diagnose the SPNA heat budget using ECCOv4. Changes in the heat content of an oceanic control volume can be caused by convergences and divergences of advective, diffusive, and surface heat fluxes within the control volume.  [Advective heat convergence] explains 87% of the total [ocean heat content] variance, the former [warming] showing similar decadal behavior to the latter [cooling], increasing over 1994–2004, and decreasing over 2005–2015. … These results demonstrate that the recent SPNA decadal trend reversal was mostly owing to advective convergences by ocean circulation … decadal variability during 1993–2015 is in largest part related to advection by horizontal gyres.

North-Atlantic-Cooling-OHC-Piecuch-2017.jpg

Yeager and Robson (2017) also point out that, like it did from the 1960s to 1980s, the North Atlantic “has again been cooling”, a trend which they and others expect to continue.   Sea surface temperatures are no warmer today than they were in the 1950s.

Yeager and Robson, 2017    [W]hile the late twentieth century Atlantic was dominated by NAO-driven THC [thermohaline circulation] variability, other mechanisms may dominate in other time periods. … More recently, the SPNA [sub polar North Atlantic] upper ocean has again been cooling, which is also thought to be related to a slowdown in the THC. A continued near-term cooling of the SPNA has been forecast by a number of prediction systems, with implications for pan-Atlantic climate.

The Southern Ocean Has Been Cooling Since The 1970s, Contrary To Models

Latif et al., 2017    The Southern Ocean featured some remarkable changes during the recent decades. For example, large parts of the Southern Ocean, despite rapidly rising atmospheric greenhouse gas concentrations, depicted a surface cooling since the 1970s, whereas most of the planet has warmed considerably. In contrast, climate models generally simulate Southern Ocean surface warming when driven with observed historical radiative forcing. The mechanisms behind the surface cooling and other prominent changes in the Southern Ocean sector climate during the recent decades, such as expanding sea ice extent, abyssal warming, and CO2 uptake, are still under debate. Observational coverage is sparse, and records are short but rapidly growing, making the Southern Ocean climate system one of the least explored. It is thus difficult to separate current trends from underlying decadal to centennial scale variability.
Turney et al., 2017    Occupying about 14% of the world’s surface, the Southern Ocean plays a fundamental role in ocean and atmosphere circulation, carbon cycling and Antarctic ice-sheet dynamics. … As a result of anomalies in the overlying wind, the surrounding waters are strongly influenced by variations in northward Ekman transport of cold fresh subantarctic surface water and anomalous fluxes of sensible and latent heat at the atmosphere–ocean interface. This has produced a cooling trend since 1979.
