NOAA/NCDC has long been associated with fabricated global warming ..... in a way, they must aspire to be identified as the epitome of manipulative, anti-science methodologies.
From time to time, NOAA also exhibits the typical your-federal-govt-at-work "competence".
On their 'Climate-At-A-Glance' (CAG) web site, NOAA reports that the contiguous U.S. has been cooling at a rate of -0.6°F per century since January 1, 1994 (see pink rectangle on image). That's a 258-month period.
Surprise! Color me a skeptic.
Per the monthly absolute temperatures and anomalies that NOAA reports for the period from Jan 1994 to June 2015, there does not appear to be any obvious means to calculate a cooling trend. In fact, using the CAG supplied NOAA dataset for temperatures during that period, there is a warming trend of 1.68°F, calculated using Excel's slope function for a linear trend.
Indeed, from the same NOAA reported data, there is a U.S. cooling trend but it does not start until February 1996. Using either NOAA's reported 'Climate-At-A-Glance' absolutes or anomalies, that trend is a -2.28°F for the 19.4 year period (233 months).
The more recent reporting from NOAA is hardly an improvement - from 2010 thru June 2015 they are reporting a -44.33°F per century cooling trend. Ummm...I don't think so.
It's highly doubtful that NOAA will be on the airwaves anytime soon discussing a -44 degree cooling trend when they're required to scream "it's-the-hottest-ever" constantly.
Summary: "Ashville, we have a problem." Okay, is this a function of just a very poorly designed web page that simply misleads the public? Or, a reporting system with really bad quality control efforts? Or competence, maybe lack thereof? Or, a management team totally distracted by their political agenda priorities prior to Paris 2015? Or, yet another successful Chinese hack penetrating government "security"?
As this chart depicts, atmospheric CO2 growth has been on a fast-track growth curve. CO2 levels have been accelerating up since 1960 - true relentless growth.
The dogmatic and conventional global warming hypothesis claims that this type of CO2 level growth will cause a dangerous increase of both atmospheric and surface temperatures, thus increasing atmospheric water vapor - i.e., humidity - leading to a positive feedback loop of non-stoppable accelerating global warming.
Clearly, as this chart of empirical evidence reveals, that has not happened. Atmospheric humidity has actually declined, while the atmosphere and ocean temperatures accelerate, decelerate and often develop cooling phases.
Unlike the monotonous, steady state, fast CO2 growth, the major climate measurements are highly variable, obviously unlinked to the CO2 input from humans.
However, per the evidence and the newest research, a case can be made that the non-acceleration and variability of global temperatures for the last 15+ years may have more to do with the 11-year cycles of sunspot activity not being as strong during recent solar peaks than the relentless CO2 growth.
Note: The dark purple, blue and red curves represent centered 37-month averages. The non-centered 37-month averages for CO2 (cyan dots) and RSS atmosphere temperature (green curve) were superimposed on the original chart found here.
The Pope's climate doomsday encyclical has generated a lot of controversy; and has probably doomed him to be eventually nominated for the Catholic 'hall of shame' for fear mongering anti-science.
Of course, it's not completely the Pope's fault for his ignorance. The Pope's gatekeepers and advisers can take much of the credit for making sure he did not hear about the actual climate science empirical evidence.
One climate doomsday scenario (among many) that continues to have no basis in climate science reality is the infamous prediction that Gaia will soon have a Venus-like atmosphere and boiling oceans...because of humans fossil fuel use. You can rest assured that Pope Francis was made aware of the potentiality of this fringe calamity.
It's a calamity that has long been pushed by the world's leading climate science alarmists.
NASA's former top climate expert, James Hansen, has been in the past a principal proponent of this particular doomsday prophecy. And of course, he provided the dramatic testimony to Congress in the summer of 1988 that really initiated the fear mongering in the U.S. regarding catastrophic global warming and climate change disasters - like turning Earth into Venus.
Unfortunately for the Pope, James Hansen and other hysterical climate doomsday soothsayers, the real world empirical evidence clearly shows that the world's climate is self-correcting and not prone to those scary predicted tipping points and runaway disasters from growing atmospheric CO2 levels.
Case in point: The Tropics (20S to 20N latitudes) - A Venus Doomsday?
The above chart plot reveals a tropical climate, as measured by satellites, experiencing a very slight cooling trend (blue curve) over the last 20 years. In contrast, the IPCC's latest climate model (CMIP5/RCP4.5) curve (green line) predicted a significant warming trend during that same 20-year period.
Going back even further, the red chart plot depicts an 83-month period of exceptional warming right after the Hansen testimony of 1988. In contrast, the IPCC climate models predicted a significant cooling trend for the Tropics for those 83 months - an abysmal failure, represented by a 7 degree trend difference between reality and prediction.
Needless to say, although we will, both the consensus climate experts and climate models have been spectacularly wrong in their doomsday projections for the Tropics, which means that human CO2 causing Venus-like conditions for Gaia has no basis in climate science reality.
It's unfortunate that this pope fell victim to his own gullibility and the anti-science machinations of his court jesters advisers. But there is good news for the Catholic masses: you can now also comfortably ignore this encyclical since it was produced from the irrational passion of fear versus the known rational, empirical climate science.
NOAA's latest U.S. temperature dataset reveals that over last 20 years (including 1996), May temperatures have been on a cooling trend: a -0.8°F/century trend.
In addition, the same dataset for 12-month periods ending May shows a cooling trend over 19 years. That trend is a -0.4°F/century.
Regardless if one refers to these climate temperature dynamics as a 'pause,' a 'stall,' a 'hiatus,' or a 'plateau,' it was not expected - no alarmist hypothesis or theory-based scenario predicted this outcome.
Note: Temperature trends are for the continental U.S. The official climate agency source of trends and chart.
Political expedience, and a craving to please, truly corrupts scientists and the science they produce...in an era when science fraud is on an exponential rise, one would think that climate agencies would be more careful with their scientific integrity...especially in a year of a major climate conference...did NOAA just provide a new Climategate-effort of science deception?...similar to what sunk Copenhagen2009?.....

The past several days has seen much written about the new revision of the NOAA global temperature dataset - a revision that supposedly eliminates the global warming 'pause' or if you prefer, the 'hiatus'.
The revision has received withering scrutiny, with multiple significant criticisms being leveled. Clearly, as the critics point out, this revision is not based on any known physical science principles, nor on any new empirical evidence, but instead on a political agenda that demands "scientists" find more global warming, pronto, for the Paris 2015 climate elite bureaucrats hookup extravaganza.
By utilizing questionable adjustments based on even more questionable assumptions, NOAA managed to produce an entirely fabricated increase in the global warming trend from 1998 to 2012. Theirs is not a real global warming event, it is essentially nothing more than statistical flimflam.
Per the critics, several key failings include:
The complete ignoring of the world's best climate measurement technologies - satellites and the Argo ocean-float array system - likely ignored because both technologies show little if any warming in their respective realms.
The authors provided a statistical significance level of a remarkably lame .10 - so lame it pretty much alone indicates this study's claims have the lasting robustness of toilet paper after flushing.
This study significantly lowered sea surface temperatures, specifically from 1998-2000. This lowering had the immediate impact of making the temperature rise from 2000-2012 appear much larger than it really was.
Study used Arctic land temperatures to manufacture rising Arctic sea temperatures - conveniently ignoring that regional sea temperatures are almost always zero (0°C) since sea ice stretches across the area for a majority of a given year.
In a rather bizarre manner that non-biased scientists would not employ, this study massively adjusted up the ocean buoy temperature measurements in order to match the ship records of engine water intake temperature; yet the buoys were designed to measure surrounding sea temperatures, and the engine intakes were not. Scientists familiar with this issue agree that the ship engine enhanced temperature measurements should have been adjusted down instead.
Despite all the ludicrous adjustment machinations this newest NOAA revision relies on, the per century global warming trend fabricated (for the 1998 to 2012 period) remains well below even the IPCC's average climate model projections.
Relevant to that last point, is the above chart. It's a comparison of warming trends during the 15-year periods ending 2012 (see blue rectangles) and 1997 (see red circles).
Using climate agency temperature anomalies that were reported as of the end of 2012, one can clearly see the dramatic drop in global warming rates from the earlier 1983-1997 period versus the period ending 2012.
Did it still warm from 1998 to 2012?
Yes, it did. But it was at a fraction of the warming trend of the previous 15 years - a definitive slowdown versus the prior warming trend.
And as the chart reveals, the CMIP models (the RCP 4.5 scenarios) expected significantly more warming than observed during 1998-2012 period. Objectively, the models predicted an accelerating warming rate, which actually failed to happen, as the empirical evidence proves.
Because of this decline ('pause'?) in global warming trends, NOAA felt compelled to simply fabricate more warming in a rather feeble attempt to make global warming seem more of a existential threat that might even scare an anti-capitalism Pope into embarrassing fear-mongering.
Unfortunately for the "scientists" at NOAA, despite all their really lame statistical shenanigans, the revised NOAA temperature trend for the 15-year period ending 2012 is still a quite tepid 0.9°C per century - indeed, the descriptor 'lukewarm' readily comes to mind.
The mountain of empirical evidence of fraud just keeps growing...massive climate record adjustments by NOAA and other climate agencies continues...blatant adjustment manipulations presented as the actual temperature measurements...all in the name of the "global warming" agenda of power-hungry elites...simply, it is an agenda of pure ideology supported by anti-science quacks producing fabrications...a disturbing FactCheck.....

A new article over at NoTricksZone brings us yet another example of scientific fraud perpetrated by the national climate agencies.
As the adjacent chart from the NTZ article documents, NOAA's definitive manipulations of a U.S. states climate records to enhance the modern global warming trend is indisputable.
As the engineering physicist who analyzed the recent NOAA dataset for Maine concluded:
"In my opinion, this is out-and-out fraud. Why did they corrupt national climate data? Global warming is a $27 billion business on an annual basis in the U.S alone...They have corrupted Maine climate data between 1895 and present by a whopping accumulated 151.2°F."
Although the Vatican (and yet another Pope) has embraced the fearmongering of anti-science and anti-empiricism, the unicorn of climate change...dangerous and accelerating global warming...still does not exist, according to the UK's HadCRUT4 dataset published by the MetOffice.....

Using the updated HC4 global anomalies dataset, since 1955 the global temperature trend for intermediate and long-term periods has never exceeded 1.8 degrees per century, let alone the fabled 2.0° mark, as of calculations based on the March 31, 2015 date.
As the adjacent graph reveals, the latest 10 year trend since 2005 has dropped to a barely measurable 0.4°/century and the last 18 years (since 1997) is an eyelash higher at 0.67°/century - and by the way, both of these figures are essentially climate-impact insignificant.
Why 1997? Well...there has been very little warming since 1997. What warming there has been is robustly below what "expert" climate models projected. Climate scientists typically refer to this unexpected deceleration as the 'hiatus' or 'pause'.
Per the chart of empirical evidence, the deceleration of global warming is evident from the fitted trend curve.
Sticking with that last 18-year trend as of March 2015, how does the most recent period stack up versus other 18-year periods when the entire HC4 dataset from 1850 is analyzed?
Since 1850, there has been 1,983 months of reported temperatures. From those, 1,768 18-year trend datapoints can be calculated.
The March 2015 18-year trend datapoint ranks number #875 - so, approximately half of the past datapoints possess a higher 18-year trend.
Yet atmospheric CO2 growth since 1964, as represented by the green circles on the graph, has been non-stoppable, blowing well past the hypothetical "safe" 350ppm level to reach the highest modern CO2 level ever.
This combination of temperature acceleration datapoints and CO2 measurements clearly demonstrates that CAGW accelerated warming does not exist; and it is unequivocally, irrefutably, undeniably and non-debatable that the world is experiencing a rather tepid, 'luke-warming' environment.
Historically, today's temperature trends are entirely within in the realm of what has taken place in the past from natural temperature variation, regardless of CO2 levels.
In other words, it is indisputable that the current climate does not suffer from "dangerous" man-made warming.
One could say that this infallible empiricism defines the non-religious, scientific climate change reality, so-to-speak.
Notes: Interpreting the above chart's blue columns: for example, since 1984 (see yellow box) the last 31 years (see corresponding blue column X-axis label) the warming trend was 1.73C/century, as of the 31-year period ending March 2015. The green circles are simple calendar year atmospheric CO2 measurements - the first (leftmost) circle represents 1964 and the last green circle is 2014. All blue columns representing temperature trends use at least 100 months of temperature measurements for the trend calculations (using less than 100 can produce extreme volatility for calculated trends - the less than 100 datapoint calculations are very interesting but can be quite misleading). Excel was used to calculate the different period trends (using Excel's slope function); Excel's charting function was used to plot the trend datapoints. Those stubborn facts: source of UK MetOffice H4 dataset; source of atmospheric annual CO2 levels.
The global "warming" charade is not about saving humanity, nor about saving polar bears...it's all about a non-environmental agenda that is being pursued by the establishment elites and powerful...and they aren't bashful about admitting it...thus, government agencies, such as NOAA, will fabricate anything and everything in support of the agenda.....
(click on graph to enlarge)
The global warming political agenda requires proof that temperatures are getting hotter.
If "hotter," then the public will of course need the government to step in and save them from dangerous hot temperatures.
But what happens when the modern maximum temperatures do not fit the agenda by not being as hot as those experienced in the distant past, earlier in the 20th century?
Well, in the case of NOAA, they just fabricate the "proof."
By simply lowering adjusting past annual maximum U.S. temperatures down until they are below the modern era temps; plus, to provide a little oomph, they raise the modern maximums a bit.
As this chart reveals, NOAA massively lowered the past temperatures prior to the 1990's. The broad black curve is the 5-year mean of the maximum U.S monthly temperatures originally measured and recorded.
And the broad blue curve? That's the 5-year mean of maximum temperatures after NOAA finished with their fabrications adjustments.
Figuratively, with a few strokes of the keyboard, NOAA manipulated the long-standing historical climate records in order to present needed "evidence" that fits with the political agenda.
Unfortunately for the reputation and credibility of science, this style of empirical evidence falsification is widespread, with government climate "scientists" leading the way it would appear.
Note: Original source of chart; the animated gif image was separated into its two frames using '7GIF.' The colors of the the two frames were then changed to be different. Then one graph was superimposed on another.
"Consensus" climate science temperature adjustments by various national climate agencies has pretty much destroyed the credibility of government funded climate researchers...currently, it has gotten so bad that hardly anyone takes seriously the predictions of the climate-doomsday cult...in fact, the only remaining believers are the die-hard fringecult leaders who prosper nicely from doing so.....
Recent examinations by analysts Paul Homewood, Tony Heller and others confirm that a wide variety of official temperature datasets have been excessively manipulated by climate "scientists" - to the point where policymakers can no longer be sure if climate records can be trusted.
The blatant temperature manipulation perpetrated on the public has been, for the most part, an esoteric issue discussed by individuals familiar with temperature record analyses. (Peer reviewed research indicates that the fake-warming likely represents 25 to 50% of reported global warming by the climate agencies.)
In the past, the mainstream press essentially ignored the anti-science temperature record fabrications, but no longer.
And as this cartoon indicates, the consensus science establishment is being mocked for the exposed temperature lies.
Wouldn't it be great if we all could just trust what the establishment science states about actual climate temperature changes and trends? But we can't, as they have categorically proven to be driven by agendas other than scientific truth. One just needs to connect-the-dots, so to speak, to discern what is really happening.
Indeed, the preponderance of evidence from the officially manipulated temperature datasets indicates fabricated cooling adjustments being applied to periods pre-1980 and a fabricated warming since 1980.
The net effect of the joint cooling and warming adjustments appears to be two-fold in support of the UN/IPCC politicalsciencepolitical "science" agenda.
One, the overall warming trend is enhanced, which is then attributed to increased CO2 by the government agency scientists, versus stating that their underlying temp adjustments were the real "enhancement" cause. Two, bureaucrats (both transnational and national), politicians and journalists demand global warming/climate change talking points - thus the creation of higher (i.e. warmer) current temps than any temperatures exhibited earlier in the 20th century.
One of the unintended and humorous consequences of climate record fabrications has been the nonsensical and irrational explanations as to why enhanced global warming is producing colder and more severe winters. The faux-warming has now necessitated the fabrication of new global warming capabilities that are entirely inconsistent with known weather physics and history.
Recent winter weather examples that have caused CAGW alarmists to expose their anti-science rationales include:
Unfortunately, the anti-science of climate science will continue since it appears to be prerequisite of research funding - in simple words, scientists are forced to support the consensus green political agenda in order to survive and thrive.
Thank you, Obama!....US DOE researchers connect-the-dots...confirm for the public, once and for all, that natural climate change was bigger!, badder!, warmer! and cooler! than the meek modern era climate...science has spoken!!...the science is settled!!...the debate is over!!...it's a consensus!!...indeed, modern warming is very natural-like, just not as robust versus the past.....

This chart was recently produced by government scientists, as noted here and here.
This single chart compilation by govt researchers confirms what multiple studies have shown over and over again...natural climate change rules, regardless of CO2 greenhouse emissions.
Several obvious points from this research pictorial.
A. Past natural climate change has produced extreme volatility and variation.
B. Reconstructed temperature proxies reveal multiple climatic periods of acceleration and levels of cooling/warming that far exceed what the modern era has experienced.
C. Modern global warming is not extreme nor unique, even compared to the relatively recent period of the Minoan/Bronze age civilizations.
D. Current temperatures would not have to drop by that much for Earth to enter an ice age glaciation period.
E. Earth has been in an overall cooling mode for the last 10 million years.
These 5 scientific factual points are indisputable, undeniable, irrefutable and unequivocal. [Editor opinion: Any scientist, politician, bureaucrat or journalist/pundit who states otherwise is a definitive climate change denier - or, maybe 'anti-science' liar would be a more apt label for those denying what climate science has proven to be fact.]
Two more points to be considered.
First, the DOE scientists who produced this chart attached instrument thermometer readings to reconstructed proxy estimates. This is truly an apple-to-orange comparison without any scientific validity. It's a science 'no-no' in lay terms. In addition, modern era proxy reconstructions reveal a temperature decline since 1960 that these DOE scientists conveniently fail to mention identify.
Second, it has been well established by multiple analysts that modern climate records have been heavily manipulated by govt "scientists" to fabricate faux-warming over vast regions of the globe. It is now estimated that large swaths have had their climate records "adjusted" upward by at least 0.4C over the last 20 years. To appreciate the huge extent of the temperature fabrication, visit these search links: here, here, here, here and charts here.
When these two considerable factors are taken into account, the actual modern warming that has occurred is likely better represented by the mauve arrow added to the chart on the right side.
Alas, in the scheme of actual climate empirical evidence, modern warming is not so much as it turns out. It's those stubborn facts, again.
Winter can be sooo cruel...especially for scientists who have long immersed themselves in the pile of manure that CO2 CAGW hysteria represents...good news, though!...NASA and James Hansen have a fallback position...namely, the previous climate hysteria predictions they and the press were pushing on Congress and the public.....

This updated NOAA U.S. temperature map is a stark reminder of the incredibly cold climate that northern and eastern areas of the US have recently experienced. The bitter cold, in particular, impacted those regions east of the Mississippi River, with states butting up against Canada taking the brunt.
It's also a reminder of those predictions by NASA experts and computer models, as promulgated during 1988 congressional testimony, that accelerated global warming would significantly impact the U.S., with many "experts" then claiming our future was one of warmer winters and no snow.
More to that point is the adjacent chart of US Nov/Dec/Jan temperatures (28 years) and trends since that 1988 testimony. It represents the following 8 states: Wisconsin, Michigan, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine (all these states are east of the Mississippi and share a border with Canada).
To summarize the chart essentials:
1. Winter temperatures (Nov/Dec/Jan) exhibit a strong variability (the blue columns). Clearly, increasing atmospheric CO2 levels during this period has not caused ever-warmer winters.
2. Many of the winters are below the 1988 average of 27.58°F, including the winters of 2014 and 2015. (see blue dashed line)
3. Despite the very warm winter of 2002, the overall warming trend (orange curves) of winter temperatures has collapsed to a cooling trend of -5.7°F. There is no escaping the obvious NOAA empirical evidence that greenhouse gases are not producing the predicted accelerated warming.
4. The 10-year average winter temperature (the green curve) peaked in 2007 from a low experienced in 1989. Without any doubt, those few very exceptional warm winters (5 of the 28 winter datapoints) have definitely moved the average up. With that said, since 2007 it has declined slightly.
Is the U.S. just a rare anomaly where a cooling winter trend, not warming, is happening? Unfortunately, for the public and CAGW-scientists, regions with cooling trends are becoming more common.
Additional current empirical evidence that CO2 does not cause dangerous "warming" winters:
Note: Source of dataset for 8-state winter temperature chart produced by Excel. Using Excel calculated the 8-state winter months average; the 10-year trends and averages that begin with year 1988 on the chart used U.S. winter (Nov/Jan/Dec) temperature data starting with November 1979.The 1988 blue-diamond column on chart represents year of James Hansen global warming testimony.
The updated NASA/Hansen climate model chart with the latest GISS and HadCRUT4 observations remains a testament to abject climate model failure by the anointed "experts"...chart includes updated GHG growth trends from IPCC AR5...not surprisingly, climate reality is very unkind to the CO2-centric computer simulation predictions...one could fairly surmise from the actual performance of models and experts that they can't predict squat...just say'n.....

No matter how many years go by, the trend towards ever worse climate model predictions continues.
Case in point: The NASA/Hansen climate model that was used by climate experts to convince the politicians, the media and pubic that the world was at severe risk for massive global warming if greenhouse gas (GHG) emissions were not drastically cut.
This model's predictions came to the forefront when NASA's James Hansen provided testimony to the U.S. Senate in 1988. As it was discovered much later, the Hansen testimony was stage-crafted for maximum fear-mongering impact, which should have been the first clue that there was a credibility issue regarding the climate model.
Before diving into the details, a short glance at the accompanying chart provides the critical policymaker insight:
Essentially, the NASA model predicted temperatures would follow the bright green curve if GHGs were not curtailed. The cyan (aqua) curve datapoints are the predicted temperatures if GHGs were curtailed. Greenhouse gases have continued their accelerated growth, yet the observed temperatures (the green and pink circles) closely match the cyan curve. Simply, the model's predictions have been spectacularly wrong, worsening by the year.
The following provides more details:
The newly published 2014 IPCC AR5 summary report bemoaned the recent significant growth increase of GHGs. The IPCC established the per year growth, prior to 2000, to be at a 1.3% rate. The IPCC AR5 reports that GHG growth has now jumped to 2.2% per year through 2010 (see more details here).
[Editor: Speaking to CO2 emissions more specifically, using the 1999 year-end global CO2 emission level as the base year, CO2 emissions have grown at an average 3.0% per year pace as of the end of 2013. That's 14 years of exceptional growth. In contrast, the 14 years of CO2 growth prior to 1988 is only 1.8% per year (read below as to why prior to 1988).]
To say that GHGs have exceeded the 'business-as-usual" (BAU) scenario would be an understatement - according to the IPCC AR5, a 70% increase has taken place, on a per year basis.
Of course, the BAU scenario was made famous by during that 1988 U.S. Senate hearing.
Per Hansen: "We have considered cases ranging from business as usual, which is scenario A, to draconian emission cuts, scenario C, which would totally eliminate net trace gas growth by year 2000."
In a peer-reviewed article supporting his testimony, he stated that the 1970s and 1980s had an approximate annual growth average of 1.5% (prior to 1988). This was the paper's BAU 'Scenario A' that he spoke of in his testimony. In his written Senate statement, he included an appendix that verifies the ~1.5% BAU estimate for GHGs, plus a chart that depicted the scenarios A, B and C.
That chart is replicated above, with Scenario 'A' being the green curve; the 'B' scenario is the orange curve; and the cyan curve is the 'C' scenario, which represents the 'draconian' emission cuts Hansen states are required to minimize potential global warming.
As stated previously, the IPCC has confirmed the rapid, continuing growth of GHGs since the end of 1999, which per the NASA climate model, should have produced global warming equal to the bright green curve on the chart.
Instead, climate reality and natural climatic forces intruded - real world temperatures since 1988 resemble the cyan temperature curve of "draconian" emission cuts that Hansen's testimony implied would necessarily make global warming safe by end of 2014.
As it turns out, some 25+ years later at the end of 2014, we currently have achieved that implied 'safe' global warming that the climate modelers and experts predicted would not happen unless there were forced gigantic emission cuts.
Objectively, the empirical evidence leads to a couple of reality-based, undeniable and incontrovertible conclusions: policymakers should not rely on the unreliable climate models - they're egregiously wrong and not getting much better; and, climate experts truly do not understand the natural forces dominating the climate system.
Notes: This updated NASA/Hansen chart now uses the current HC4 and GISS V3 datasets, as of 12/31/14. Instead of plotting individual year datapoints for observed temperatures, plotted 3-year (36-month averages ending in December): this reflects an expectation that models can't predict accurately every annual period, but over longer 3-year periods the model and observation trends should better match. Starting in 1960, both GISS and HC4 3-year averages were offset to start at zero (0.0°C) anomaly. To reduce the clutter on chart, only 'even' year observed 3-year temperature datapoints were plotted. The small insert chart is data from IPCC AR5 summary report. The green, orange and cyan Hansen model plots came from this climate-doomsday site.
Climate science continues to document the powerful, repeating natural patterns that produce the ups/downs of climate change...yet, many political, journalism, celebrity elites, and newly-minted wannabes deny the existence of these past, current and future climate patterns...to the point of grossly misleading the public and constituents in regards to natural climate change, natural global warming, and yes, natural worldwide cooling...so, is it plain anti-science that drives their denial?...an unfathomable ignorance?...or just the intellectually-lame desire to be politically correct?.....

Using the UK's MetOffice global HadCRUT4 (HC4) dataset as a proxy for long-term climate change, it allows for a breakdown of when such changes occurred.
For this article's definitional purposes, long-term change is defined at those points where the HC4 30-year global average shifted to a new level (up or down) by 0.1°C, for at least 12-months in a row.
[Editor: Why ±0.1 changes and not ±0.01? Because long-term changes of hundredths of a degree is an absurd and statistically bogus change-assessment technique for 12 months, let alone 360 months.]
The adjacent chart depicts those ±0.1 changes. As can be observed, there have been a total of 10 shifts since the 1850-beginning of this global instrument dataset.
There was a shift down in the global 30-year average starting in July 1909, for a period that extended to October 1928. The next full 0.1°C shift arrived in November 1928 when the 30-year average increased by 0.1°C, attaining its previous level.
That was then followed by 3 more shifts, each of different lengths.
Then the same exact pattern of shifting repeats, with 1 cooling shift followed by 4 warming shifts.
The warming since the end of the Little Ice Age (LIA) did not have a major impact on long-term HC4 averages until the early 1900's.
Natural global warming since the LIA-rebound started has not been consistent, nor even predictable.
As represented by the 30-year global average shifts, the first span of global warming (consisting of the first 4 shifts up) was very lengthy, reaching all the way into the 1970's - this long span being primarily well before the gargantuan consumer/industrial CO2 emissions from the late 20th century of the modern era.
The amount of long-term increase for the last 4 shifts equals +0.4°C, the same as the earlier 'up' shifts, but it occurred over a shorter time span.
Does all of the above mean that the future will be an exact repeat of the pattern? Well, the definitive answer to that is 'no'.
There is no denying that, in general, modern climate change closely resembles what has taken place in the past. The similarities are evident, despite short-term climate variations that produce observable differences in duration, levels and intensity.
As the latest peer-reviewed research indicates, modern climate scientists are finally rediscovering (for example and example) the climate truths that their predecessors were aware of: natural earthly/solar/cosmic forces produce repeating (and similar) climate oscillations/cycles, creating dominant influences that dictate overall patterns for long-term climate change.
Yes, the human influence does exist, but it is a distinctly minor player in the long-term scheme of climate patterns.
And because these amazing pattern similarities happen in a chaotic system, they can neither be predicted, nor controlled. Those stubborn facts are continually ignored by advocates of human-caused climate change predictions.
Note: This monthly temperature dataset and Excel used to calculate moving 30-year averages. First, monthly anomalies were used to calculate a 12-month average for each month. Then using an estimate of 14.0C for the global temperature average of the 20th century, 12-month absolute temperatures were calculated from the calculated 12-month average anomalies. Finally, 30-year (360-month) absolute global averages were calculated. Excel's rounding function used to identify ±0.1C changes.
The growth rate of CO2 has never been greater...and climate-doomsday cult shrieking has never been shriek-ier...yet...to much embarrassment...2014 wasn't the 'warmest-evah'!...maybe next year, though...in the meantime, the history of global temperatures and CO2 growth since 1850 in a single chart.....
(click on chart to enlarge)
The HadCRUT4 (HC4) global temperature dataset is now considered the gold-standard for surface temperatures (the previous gold-standard was the HC3 dataset).
Using the annual HC4 calculated temperatures, the adjoining chart was created.
As observed, the global temperatures have essentially stalled since 1998, with 2014 likely not greater than that reached in 1998.
This chart also delineates the two major warming periods since 1850. The first from 1917 to 1944; the last from 1976 to 1998. The warming trend increase of the latter over the former was a paltry +0.4 per century - an increase well within what one would expect from natural variability, regardless of CO2 levels.
And then there's the CO2 growth itself.
The 20-year growth rates show an almost continuous climb since the early 1950's. At the end of 2014, it was the highest ever. This greater than 'business-as-usual' growth was discussed in the latest IPCC AR5 report - the growth rate for total greenhouse gases has followed a similar path.
Finally, the chart depicts where the much discussed 2º, 4º and 6º increases over the 1850 global temperature would be... see the red dashed lines.
How long to reach the 2º mark that elites fear so much? Well, per the last 18 years, that trend would indicate another 150+ years before the 2 degree increase would ever be reached.
From this empirical evidence, it would be fair to surmise that invoking more big government polices and regulations to combat unsubstantiated climate-doomsday speculation might not be in the best interests of the public.
We've said it before...climate models can't predict squat...current scenarios of global climate temperatures and level of temp change already reveal a massive failure...policymakers and taxpayers should completely disregard the virtual computer simulations of climate doomsday proposed by UN's IPCC.....

This is not brain surgery. This is not rocket science. This is not nuclear physics.
Climate science fiction: For the last 10 year-period, the UN's IPCC climate models predicted greenhouse global warming equaling a per century trend of 1.7°C.
Climate fact: The globe warmed at only a +0.2°C/century trend. In other words, global warming has stalled, paused, or if one prefers, in a hiatus condition.
Simply put, the computer simulations programmed by CAGW alarmists produced virtual global warming 8 times greater than climate reality.
This spectacular failure by models (developed by the "consensus" experts) is well documented. And as of this date, there are over 50+excuses reasons by these "experts" as to why their billion-dollar climate simulations have turned out to be worthless for policymakers.

Claims of rapid, accelerating, dangerous and unequivocal global warming from CO2 and other greenhouse gases means that should be happening...especially for the oceans that represent about 72% of the Earth's surface...yet the latest empirical evidence shows the above adjectives are big fat lies when it comes to this gigantic thermal sink...Ooops...those stubborn facts strike again.....

Ocean expert Bob Tisdale's recent article delineated the various warming trends of the key ocean basins.
His dataset for the adjacent chart comes from the ARGO system, which is the most sophisticated technology in use for measuring ocean depth warming. (More on that dataset here.)
Previously, 'C3' published an article about the non-"unequivocal" nature of global warming. That article also provided insight as to locations of the much feared "dangerous" and "rapid" global warming - turns out the only locations are the concrete/asphalt environs of airports and major urban/metro areas.
So, what does the actual ocean-deep warming empirical evidence presented on this chart tell us? (Remember, this is the warmed-up data presented after bureaucrat sceintists adjusted the raw measurment data.)
#1. On a per century trend basis, global warming of the oceans is barely happening.
#2. Unequivocal ocean warming is not taking place - note that neither the Pacific or North Atlantic exhibit a warming that is climate significant (in fact, one could claim their warming is likely a function of measurement error and/or those "adjustments").
#3. The oceans are not going to be boiling from CO2 emissions as predicted by NASA's top climate expert.
#4. If 72% of the world's surface and Earth's atmosphere are not exhibiting accelerating and dangerous warming, then any claim that the entire globe is exhibiting those characteristics is a scientific falsehood, i.e. a blatant lie.
Hmmm...those stubborn climate facts can be sooo annoying.
Powerful and wealthy elites, global warming alarmists and climate-doomsday cult'sters' often make statements like..."it is indisputable, global warming is unequivocal"...but here's the problem...that is an exceptionally misleading, anti-science piece of propaganda that should never be tolerated...even NOAA's empirical evidence shows the lie of that type of statement.....

In previous articles, evidence was presented that much of the globe has not warmed since year 2000 - areas such as regions of the world's ocean, the lower atmosphere and major regions of the U.S.
However, if global warming is "unequivocal" from CO2 emissions and other greenhouse gases as claimed, then how is it possible that major components and areas of the world are not warming?
As it turns out, where one actually measures temperature change is a huge factor whether the end result is "global" warming or not.
Simply put, as all climate scientists agree, urban/metro and airport areas are robustly warmer than surrounding areas, during both the daylight and night hours. And, as it turns out, they are warming at multiple times greater rate than rural regions.
They are not warmer because of more CO2 and methane. They are warmer because they have more people, cars, schools, stores, restaurants, planes, trucks, buses, trains, factories, concrete, asphalt, buildings, parking lots and etc.
And because of some very incredibly shortsighted decisions, the majority of climate stations are now located in the urban/airport areas, with most of the rural stations being eliminated. Thus, there now exists a built in bias impacting global warming calculations, which heat-up the actual climate reality.
How big is that bias impact? That's what the adjacent graph helps to reveal.
Take Reagan National Airport in the Washington DC metro. It's warming at an astounding +14.6F degrees per century pace over the last 15 years. Now compare that to a rural area about 170 miles west of DC, in the very northwest part of Maryland. (This portion of the country is called the Allegheny Plateau region a NOAA/NCDC designated climate division). It's cooling at a -3.1°F per century rate.
An 18 degree warming rate difference within a 3-hour journey? CO2 is not responsible for that.
So, why do the U.S. politicos, elites and media believe the world is "unequivocally" warming?
Because they live and work in highly urbanized areas that have the necessary attributes that cause a positive temperature feedback - often referred to as the Urban Heat Island effect (UHI). They are oblivious to the fact most of the world's populace does not live in these concrete-cocoon heat traps and are not experiencing ludicrous warming where the wealthy and powerful congregate.
Again, examine the above chart. Urban/airport warming locations (Reagan Natl, Dulles, Richmond and Baltimore) exhibit fast "global" warming growth. The two highly populated states (Virginia & Maryland) surrounding these urban regions show more moderate warming. And nearby rural areas (the Appalachia Mountain and Allegheny Plateau areas of Maryland) actually have cooled over the last 15 years.
Importantly, the rural areas' temperature cooling are more in line with the entire continental US climate, as shown.
Why does the U.S. exhibit an overall cooling trend for the last 15 years? Obviously, geographically, the U.S. has a much greater abundance of rural areas, similar to the Allegheny Plateau region, than urban/airport complexes. In fact, it is claimed over 90% of the U.S. is considered rural.
Memo to Republicans: For discussions and debates about climate change, use only official weather/climate station thermometer datasets located in rural regions and/or from satellites. Urban/airport thermometers do not measure temperature change from CO2/GHG climate change - they measure temperature change produced by the concrete-cocoon urbanization. Demand that NOAA/NASA/EPA primarily report satellite/rural temperature changes as a leading indicator for potential greenhouse gas influences. Dismiss with contempt those global warming calculations that are quoted which include the hot airport/urban thermometers.
Note: Source for urban and regional 15-year annual temperature datasets. Above Excel chart only shows per century linear trends calculated by Excel, not the annual datapoints. For the chart, adjusted y-axis to better fit all trends on a single viewable image for the article.
Some 25 years after NASA's stage-crafted Senate testimony regarding the dangers of global warming from CO2, the public has learned not to trust U.S. climate agencies...NOAA and NASA just confirmed why they still should not enjoy the public's trust...the black cloud of the "climate of lies" just got darker.....

Here's a reporter's excellent synopsis of what he found by simply investigating the exuberant claims of the "hottest year" and "warmest-ever"!
Although a lot of scientists (two examples, here and here) were quickly labeling the claims bogus, David Rose of the UK's Daily Mail was the first major newsprint reporter to actually do the journalism legwork that discredits claims by NASA (and NOAA). (Per standard operating procedure, the American press simply reported the NASA/NOAA press releases, with complete gullibility.)
The adjacent graph readily explains the NASA deceit (NOAA's deceit is similar). When the known error bars are added to the reported annual temperatures since 1998, one discovers that multiple previous years may have been warmer than 2014.
The facts are that no scientist can determine the world's "hottest" temperature - due to the statistical uncertainty, the margin of error doesn't allow for it. And it's simply lying not to inform the public of this.
That's why NASA's "experts" now say they are only 38% sure about 2014 being the "warmest-ever".
Yet these government-funded scientists will continue to mislead the public about the climate reality, and most "journalists" are too intellectually lazy (brainless?) or just too complicit to report the objective truth .
Like most inconvenient stubborn climate facts, the mainstream media propaganda that modern global warming is "unprecedented" doesn't stand up to even simple scrutiny of the facts...with little effort, one can identify, via NOAA, earlier periods where global warming was greater and increasing faster...is this a case of journalists being deniers of empirical evidence?.....
As this chart of empirical evidence demonstrates, global warming has taken place in the past, well before the explosion of CO2 and other greenhouse gases.
And there have been times when earlier warming either equaled or exceeded modern warming. For the 25-year period shown, early 20th century warming was actually greater than the 25-yr warming through 2014.
For almost all consumers of the mainstream press, they are totally unaware that recent warming has no 'chops', so to speak.
It is not "unprecedented" and it certainly is less rapid than the earlier period. Also, the modern warming rate exhibits a 1.16°C per century trend. The earlier period? A 1.75°C/century trend.
Boiling it down to the numbers...that's 1.5x faster warming for 1920-1944, yet modern CO2 emissions had a growth 5.6x greater. That's the opposite of expert predictions.
Accurate and fair to say, modern warming is not exceptional.
Regardless of this unequivocal and indisputable scientific empirical evidence, which challenges the "consensus" global warming orthodoxy, the mainstream media chooses to gleefully push the latest discredited propaganda regarding the "hottest year ever" - an event that has been happening since the end of Little Ice Age, with an astoundingly great frequency.
Facts rule. The 'PR' exaggerations and embellishments are just anti-science dressed in those old fearmongering clothes. One's got to sell newspapers or web page hits, no?
Note: Source for annual NOAA temperatures used in Excel to calculate and plot 25-year temperature changes and linear trends. For the earlier period (1920-1944), 1919 was used as the base year; for the modern era, 1989 was the base year.
The world's climate "experts" long ago predicted extreme, rapid and dangerous warming for land masses occupying the higher latitudes...extreme warming for those subarctic and polar regions... Canada's climate must not have gotten the NASA memo.....
(click on table to enlarge)
NASA's climate experts are on record for predicting all sorts of climate catastrophes, including extreme warming of the world's 'higher' latitudes (the world's polar/subpolar regions).
Certainly for Antarctica, that prediction was simply a spectacular failure.
Now comes information that NASA's "hottest-ever" year/decade has not produced a single hot temperature record in Canada since 1961. With Canadian lands mostly occupying the higher latitudes ('subarctic' starts at 50N), this is remarkable empirical evidence that the predicted extreme climate change is not so extreme.
The adjacent table of Canadian hottest temperatures recorded documents that this massive area near the top of the world has not experienced the natural hotter climate that it once had during the 1930s and 40s.
The table also includes the last 15 years of Canadian warmest temperatures - not a single year coming close to previous records with the exception of year 2007.
The global warming "warmest" year ever was finally delivered...although with some birthing difficulties...NASA had to "adjust" its previous 2014 monthly temperatures to eek out another +0.04 deg before adding December's anomaly...even with that tomfoolery, the outlook for "rapid and dangerous" warming is not so hot.....
(click on chart to enlarge)
So, to put the "warmest-year-ever" into some context, 2014 was a measly +0.07C degree warmer than 1998. And that pretty much confirms that a global warming pause/hiatus/stall has been in effect since 1998, as discussed here and here.
Other interesting context:
1. Leaving super El Niño year 1998 out of the calculation, the 15-year increase over 1982 (1982-1997) was +0.35°C - a per year increase of +0.024.
2. Again, leaving 1998 out, the recent 15-year increase over 1999 (1999-2014) was just +0.12°C, for a per year increase of only +0.008.
3.The chart plots what those respective per year increases would turn into if they continued for the 85 years until the beginning of year 2100.
4. As seen, the earlier period had a warming per year almost 3 times greater than the last 15 years - did we say 'pause'?
5. Of course, the warming linear trend over that most recent 1999-2014 span (including NASA's newest hottest year/decade ever) is an even bigger LOL - a trend that equates to +0.26°C increase by 2100.
6. And, this 'not-so-hot' warming over the last 15 years took place when greenhouse gases reached record levels, and as the IPCC documented, are growing at an ever faster pace.
Conclusion: Catastrophic global warming, as NASA envisions, remains an elusive mythical possibility, despite their best efforts at paper-temperature enhancements. The "warmest-ever" claim is mere propaganda without any scientific or climate significance.
And NASA's "warming" over 1998 record? Less than warm spit and within the error bars.
The advanced sophistication of satellites allows for the precise recording of empirical measurements...these capabilities captured the stunning natural change in global temperatures during the 1998 Super El Niño...a dramatic climate change shift that remains unrivaled since....
The super El Niño of 1998 made obvious to researchers of how natural climate phenomenons can generate huge changes that are felt for years.
Using an average of each year's monthly temperature anomalies (satellite measured), the adjacent chart's columns depict the huge shift in global temperatures from the prior 1998 level to the post-1998 level.
According to the state-of-the-art technology used by climate scientists, global warming has been unequaled since this 1998 natural event.
The only year that came close to the 1998 global temperature was 2010.
Although no single year has yet bested the 1998 temp record, the 16-year average after 1998 (including 2014) is significantly higher than the 16-year period prior. Natural climate change dramatically shifted global temperatures up, and they have not returned to the previous average level.
Instead, the annual global temperatures since 1998 have shown considerable variation, but do not reflect a pattern of temperature climate change shift - a shift only delivered by a natual phenomenon (like a super El Niño). In fact, the much researched 'Hiatus', which has existed for the last 15+ years, corroborates the lack of any impactful climate change since 1998.
As all scientists concur, the El Nino/La Nina climate oscillations take place without any human intervention or influence. Their frequency and intensity are a result of the chaotic climate system that makes it impossible for "experts" and computer models to accurately predict. Yet, when a 'big one' does occur the implications worldwide are enormous.
The overall billions spent on satellite technology has resulted in scientists being able to not only monitor these climate-significant ENSO events, the sophisticated technology has also proven to be the best means to measure the world's climate temperatures, 24/7, across the entire globe (99.6%) on a daily basis.
One way to assess the superb and spectacular satellite coverage is to envision over 127 million thermometers placed on the globe constantly taking temperature readings. In contrast, the traditional/conventional means of measuring temperatures by NOAA/NASA/UKMetOffice rely on less than 5,000 thermometers, each one supposedly recording temperature changes for a land area equal to the size of Spain.
So how does that old, traditional method work in order to determine a global temperature then? Essentially, they measure temperatures in a given specific location then use that sparse information combined with formulas to guesstimate temperatures in nearby regions.
Well, that's not too precise and is fraught with errors/biases that have to be constantly adjusted for. That's why it takes several weeks of number crunching and "adjusting" after the satellites have already reported their gold-standard global measurements.
For a good write-up on the difference between the state-of-the-art measurement technology and the old, conventional means, go here.
In the meantime, major climate change seems to be in a stalled status until the next major natural phenomenon takes place.
CAGW proponents have a long-held belief that CO2 emissions and other greenhouse gases are rapidly warming the Antarctica continent along with the surrounding oceans...further, this out-of-control warming is quickly melting sea ice and the South Pole's massive ice sheets...turns out, it's a case of unrepentant denial of climate reality.....
(click on graph to enlarge)
Way back in 1988, a NASA climate expert gave testimony that the 'high latitudes' (i.e. polar) would experience greater warming due to growth of human greenhouse gases (GHGs), including CO2 emissions.
This prediction was seized upon by global warming advocates as "proof" that the South Pole's unprecedented warming would melt sea ice and cause melting ice sheets to collapse, raising ocean levels and thus submerging worldwide coastal areas.
Indeed, there is strong evidence that GHGs have risen considerably - even to a greater extent then the feared 'business-as-usual' scenario NASA/GISS experts promulgated.
Yet the newest empirical research completely counters the fears and beliefs of the CAGW crowd: over the satellite era, some 30+ years, Antarctica's ice sheets have slightly grown and the South Pole's sea ice extent is at record levels.
Then there is the proverbial elephant in the CAGW room: the Antarctica region is not warming, per the advanced satellite technology of NASA. Those stubborn facts are indisputable and unequivocal.
Yet, denial of this empirical scientific evidence remains widespread, preventing a rational debate about the real implications of the ongoing natural climate change.
[Update: A reader inquired as to the correlation between the temperature anonmalies and monthly CO2 (ppm) levels - it was 0.015. This figure suggests that seeking a link between CO2 and South Pole temps may be barking up the wrong tree, so to speak.]
Do you recall when climate "experts" told us it's was all about physics...that increasing CO2 atmospheric CO2 levels would absolutely produce perilous, breakneck accelerating climate temps...they said it was all "consensus" science and, btw, it's the physics, stupid...ooops, those pesky and stubborn facts strike again.....

Clearly, over the last 30 years when CO2 emissions and other greenhouse gases were skyrocketing, temperature trends here in the U.S. were significantly decelerating.
The deceleration of temperature warming is also seen in the major satellite measurements and the global land and sea observations, although not as pronounced as what took place in the continental U.S.
When the correlation is calculated for the chart's temperature trends and the average CO2 levels for each time period, the result is a -0.93 with a r2 of +0.86. That puts it in the universe of almost a perfect inverse (negative) correlation - higher CO2 levels seemingly drives temperatures to deceleration and cooling.
We say 'seemingly.' First, it pays to remember that trends are not predictions and don't go on forever - they change. Second, today's negative correlation could go positive in the not too distant future. And of course, third, whether it's positive or negative correlation it does not prove cause.
With those caveats stated, it is absolutely true that the consensus "physics" is not supported by the actual empirical climate evidence over more recent years. Also, the "clear and present danger" of global warming for the U.S. is a generous mix of hysteria, myth and fiction. Science factual truth is not in this mainstream mix it would appear.
Note: Using Excel and the U.S. temperature dataset from this source, one can calculate the monthly temperature anomalies from the absolute temperatures (used the 1901-2000 baseline for each month); Excel's slope function will then provide the trends for each time period; and then Excel can plot the resulting trend columns. This is the annual CO2 dataset used to calculate each period's average CO2 level. Don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
Remember when those NASA/NOAA climate experts predicted a rapidly dangerous warming for Americans?...based on the last 15 years, coastal urban elites just might consider moving to fly-over-country where cooling rules...their dedication to the absurd beloved precautionary principle certainly seems to dictate this simple precaution.....
As this NOAA/NCDC regional climate map reveals, the vast majority of the continental U.S. has not warmed for the last 15 calendar years.
Specifically, for the entire continental U.S, the 2000-2014 calendar span has seen a -2.7°F/century cooling while 7 of the 9 climate regions had cooling or temperature trend stability.
However, there are two regions of the U.S. that have experienced warming trends - on the east and west coasts.
It is highly doubtful that global CO2 emissions would only affect these two geographic areas and not "global warm" the rest of the country. Objectively, it's more likely that there are other micro-regional climatic and human factors involved for the specific coastal state warmings.
Since 1997, the continental U.S. suffers from a significant cooling trend, per NOAA...will CO2 emissions be able to save us from the looming next ice age?.....
(click on image to enlarge)
As NOAA is now reporting, the U.S. is in the midst of an extended cooling trend - 18 years and counting.
According to the IPCC and 97% of all "expert" climate scientists, the explosive growth of CO2 emissions and other trace greenhouse gases should have caused accelerated warming, not cooling.
The cooling trend is at a -1.9°F per century for the last 18 years. And since the end of the 20th century, the cooling has accelerated to a -3.5°F trend/century (years 1999 thru 2014) . That would be a doubling-down on 'Ooops', so to speak.
2014 the "hottest" U.S. year ever meme? Nope, didn't happen. In fact, this past year turned out to be the 5th coolest during that 18-year period.
Here is an interesting task for any CO2-centric global warming/climate change alarmist:
Identify from the 1980-1990's a single NOAA/NCDC/NASA climate expert on the taxpayer dole, at that time, who publicly stated this was a likely result. And the billion-dollar+ government-funded climate model(s) that actually predicted this very inconvenient climate cooling outcome.
In front of cameras, a hot and sweaty James Hansen of NASA gave his famous global warmingEOTWAWKItestimony...lucky for the rest of us, this climate "expert" was spectacularly wrong.....
(click on graph to enlarge)
During a hot June 1988, NASA's James Hansen provided a provocative, stage-crafted testimony to the U.S. Senate.
His message? The world of 1988 was the hottest ever, since the 1800's, and it was due to humans' fossil fuel CO2 emissions; and more importantly, global warming would continue its upward path, rapidly getting worse and then becoming a threat to civilization unless CO2 emissions were constrained - i.e. reduced significantly.
Why his EOTWAWKI message? Because the modern crystal ball - his computer climate model simulations - told him so.
This chart plots the global temperatures using the most advanced, costly climate measuring technology provided to the scientific community by the American taxpayer. The empirical measurement evidence over the last 26.5 years since his testimony tells a different story than what Hansen predicted.
What do the satellites say? This state-of-the-art measurement technology ignores crystal ball predictions by experts and instead objectively reports that over the last 18 years "global warming" has been a non-issue. Despite record amounts of greenhouse gases being spewed into the atmosphere, global warming has not accelerated and has not become a threat.
How bad were Hansen's computer model predictions?
In his testimony, he spoke of causation between global warming and CO2 emissions - the more CO2 released, the greater and faster temps will rise. Yet, over the last 18 years, the world has experienced a very tiny cooling trend, per the satellites. And the "causation"? Well...ahem...calculating the statistical correlation between global temperatures and CO2 ppm levels over the last 18 years produces a negative correlation, with a r2 of 0.0004.
Dr. Hansen does deserve credit however. The first 8.5 years after his testimony, satellites measured the global warming trend at a +1.22°C increase by 2100AD. And the r2 for temperatures and CO2 was 0.21 (note to climatologists of alarmism persuasion: one does not want to make predictions of catastrophe with this statistical attribute level).
The conclusion? The end of the global warming 'EOTWAWKI' as we know it, no? Damn those stubborn facts!
As the mainstream press gets ready to unleash an untold number of the "warmest year ever" propaganda stories for year-end 2014, it begs the question...in the context of long-term climate change, does the "warmest" or "coldest" for any given year matter in any meaningful way?...actually, it does not, per the empirical evidence.....
(click on graph to enlarge)
The global warming slowdown (or "hiatus," "stall," "plateau," "pause" and etc.) has been widely discussed across a broad spectrum of web and print publications, including prominent science journals and peer-reviewed research, which indicates a 100% acceptance of the extended slowdown.
The realization and analysis of this lack of significant warming has produced a cornucopia of studies and expert opinions as to why the global climate went into a completely unexpected stall mode - so far, there are some 50+ scientific rationales that have been put forward to explain the phenomenon.
Since climate science remains unsettled, the current consensus is that there is a non-consensus regarding the globe's dramatic deviation form the CO2-centric "expert" climate models. Indeed, there is no shortage of empirical evidence documenting the ever-enlarging discrepancy.
Unfortunately, despite the indisputable and consensus scientific recognition that a temperature plateau exists, and the lively debate within science circles as to why, there are elite green alarmists who claim the 'standstill' is a hoax or does not exist - essentially, that is sheer climate-change denialism by deniers performing in anti-science, denialist roles.
On top of such denial travesties, the mainstream press is trying to change the focus away from the significance of the global warming slowdown and climate model failure to the incredibly small increase in warming that allows them to shout report that 2014 is the "warmest" year ever.
The term "warmest" (as in day, week, month, spring, summer, autumn, winter, year, decade and so on) has become the last propaganda refuge of those who either deny the global pause or just want everyone to forget its importance. Utilizing the terminology of "warmest" reveals the ultimate cherry-picking agenda.
However, since the Little Ice Age (LIA) end during the 1800's, the world has been constantly producing new "warmest-ever" records - it's entirely normal within the climate record, and will happen even when a temperature change hiatus exists.
To that point, both warm and cold years can coexist during longer periods of temperature stability, as multiple global and regional records demonstrate. In addition, it's unquestionable that severe/extreme weather events can take place, regardless if it is the "coldest" or "warmest" year.
As the adjacent chart depicts, rapid cooling and warming climate changes can occur very quickly. The chart plots both the acceleration and deceleration of temperatures (ie, per century trends) over moving 12-month periods (light red curve) since 1850.
Over short-term horizons, global temperatures have been known to accelerate/decelerate at a ±70°C rate.
Since 1999, there have been periods when temps increased at a +35°C/century rate, which would obviously produce some very warm years; while during the same 15-year span, there have been periods when temps decelerated ay -39°C/century rate, which would have obviously produced interim cold periods. This is what the empirical evidence shows.
Now think about that last paragraph. Over the last 15 years there has been incredible shifts in temp trends, yet the mainstream press doesn't report on that. Instead the press reports excessively about a given period being all of 1 to 2 hundredths of a degree warmer than a previous year. The robust alarmist hysteria of "journalism" is sadly evident 24/7.
Okay, back to climate reality and the basic facts: Temperature changes. Trends increase, then decrease. It just happens. It's natural. It will continue to do so. And it has occurred since instrumental climate records have been kept and proxy temperature reconstructions have been created.
Speaking of instrumental records, back to the included chart for more evidence of extreme climate change. The HadCRUT4 instrumental record since 1850 shows some big extremes, which have been identified on the chart as those periods exhibiting temperature trends greater than ±50°C.
Those specific warming and cooling extreme incidents have been identified with the years they took place, and there are some common traits recognizable.
All the huge extreme changes took place over 40 years ago, with the vast majority being prior to 1950.
The huge CO2 emissions have not produced a single global warming acceleration extreme since 1951, over 60 years ago.
Since the 1970's, the climate extremes' range appears to be narrowing, with each accelerated warming and cooling trend rate getting smaller.
And when major (minor too) extremes occur, the climate system does not hit a "tipping point" of positive feedbacks. Instead, the natural climate responds with negative feedbacks to bring the climate back to some level of short equilibrium.
The chart also plots the moving 180-month (15 year) acceleration/deceleration of temperature trends (the dark blue curve).
Clearly, despite all the modern CO2 emissions, all the gyrations of the 12-month per century trends, and all the recent "warmest" years ever, the 15-year global warming trend has not deviated much from the past. Statistically, as of October 2014, that trend is below the median of all 180-month trends that took place in the past ( 1,801 1,799 trend datapoints to be exact).
Sidebar factoid: During 1922, the 15-year per century warming trend reached a level that was 3 times greater than today's 15-year trend - that is a trend sans the gigantic cumulative human CO2 emissions resident in today's atmosphere. Is 1922 the only pre-1950 period when the 15-year trend exceeds today's? Nope (remember, October 2014 is below the historical median).
What does all of the above mean?
Today's global warming is neither civilization-ending, dangerous, rapid, nor quickly accelerating. It continues at a long-term pace that humans have not markedly influenced, per the empirical evidence. Thus, the proper response to a claim of a new "warmest" year is appropriately: 'so what?'
As shown, those stubborn facts of empirical evidence are relentless. The continuing long-term, natural warming climate trend since the LIA has been a constant, yet combined with amazing short-term periods of abrupt change that produce exceptionally warm years and cold years.
These are the scientific climate facts. They are unequivocal, immutable, indisputable, irrefutable, undeniable and non-debatable. It's called natural climate. It happens.
Now, all of the above should not go without the following caveats: today's temperature trends are not forever. Trends are not predictions nor projections. As the plotted evidence indicates, the climate can change rapidly, going from cooling to warming back to cooling over short time spans. Any cool/warm trend has the potential to become a much longer, climate significant trend. And it's reasonable caveat to assume CO2 emissions have an impact, but likely a very trivial one (and easily overwhelmed) versus the natural climate change impact.
There is no expert (of course, that doesn't keep most experts from speculating) who can predict how much longer the pause will continue and whether it will morph into global cooling or a return to greater warming. And by the way, if the latter, many people are already debating that potential and what it will mean - more confirmation that climate science is never "settled."
When one connects the dots, so to speak, at the end of the day there have been absolutely zero climate models and/or experts that predicted the recent empirical climate outcomes that the above chart delineates - that's correct, none.
And finally, the infamous "97%" scientist consensus that CAGW proponents often fall back on when empirical evidence, such as above, eviscerates their CO2-warming alarmism, has been seriously and embarrassingly debunked, multiple times. Read here and here.

In the previous 'C3' article, we looked at U.S. temperatures since 1988 when a NASA climate expert in U.S. senate testimony made predictions of near-future catastrophic climate change and, of course, dangerous global warming.
As the article documented, temperatures in the U.S. have essentially been at a standstill over the last 10+ years, and catastrophic climate change (with its millions of IPCC predicted "climate refugees") is nowhere to be found.
The end result is the undeniable evidence that America's climate records are non-consistent with the well publicized climate expert climate predictions, and also with the billion dollar super-computer models that experts and mainstream journalists claim to be climate-omniscient.
It begs the question: Is the non-consistent climate reality in the U.S. also found in other parts of the world?
Turns out that the UK climate records, as represented by the Central England Temperature (CET) dataset, reveals the same expert abject failures and non-consistency with model simulations. "Rapid" and "dangerous" accelerated warming hasn't taken place there either.
Unlike the continental U.S., with its abundance of micro and regional climates, the small island area of Great Britain affords less climate variety yet produces similar warming/cooling trends over the recent past.
Like the U.S. dataset plots, the CET dataset is for the full 26 years (312 months through Nov. 2014) since late 1988 when both UK and U.S. catastrophic climate proponents initiated their public fearmongering campaign - the year of James Hansen's scare-testimony.
The adjacent UK chart depicts both the plots for 60-month temperature and CO2 averages. Clearly, the predicted rise in temperature due to higher CO2 levels has not happened - this is not consistent with any climate model simulation that the experts tout.
With a r2 of 0.00 between monthly CO2 and temperatures values, the UK climate records also confirm the legitimate dismissal of the argument that CO2 acts as a "control knob" - some type of global temperature thermostat that UN elite bureaucrats and national politicians thought they could just dial for a desired climate.
And that "warming" trend for the last 13 years that just scares-the-poopie out of UK's elites? A -4.8°C per century...yep, a significant cooling trend.
In summary, the combined CET and U.S. climate records add to the empirical evidence disproving the hyperbole for CO2-caused disastrous global warming and catastrophic climate change. In reality the hyperbole is without any scientific validation.
Damn those stubborn facts.

The mainstream media's current du jour "climate science" claim is that 2014 is headed towards being the world's "warmest" year, ever.
Unfortunately, for the media that pushes the hysterical, that claim is actually without statistical merit, since the uncertainty error bars are large. In statistical terms, there's a darn good chance it's not the warmest year.
Then there is the jumbo elephant in the press room that "journalists" flat-out don't acknowledge, let alone report: the state-of-the-art climate satellite technology completely undercuts the world's "warmest year" hype.
And then there is the whole issue of where exactly is all this "dangerous," "out-of-control" warming taking place. For example, is it happening here in the U.S.?
Based on the multitude of anti-science, exaggerated "warmest-year-ever" paragraphs being produced by American reporters, one would think the good citizens of the U.S. are in the midst of the civilization-ending climate-fry.
But, as usual, the empirical evidence reveals the absolute distortions the media fabricates, per the latest U.S. climate records from NOAA.
Case in point: the adjacent graph is a plot for the last 26 years (312 months) of U.S. temperatures through November 2014 - since 1988. The red curve is a 60-month average that clearly indicates "global warming" in the U.S. has gone AWOL for at least a decade - on 'hiatus,' so to speak.
Then there is the 60-month plot of CO2 emissions (black dots), which obviously tells a different story then the press fabrication that the "rapid" global warming we are "suffering" from is a direct result of human CO2 emissions.
Hmmm...clearly temperatures do not react to CO2 as those crack science reporters "report."
This NOAA empirical evidence is unequivocal and indisputable, yet the mainstream media refuses to inform the American public of these most basic climate record facts.
So why did we pick 1988 as a starting point for this analysis?
Back in the summer of 1988, NASA had its climate expert, James Hansen, testify before the U.S. Senate. In his testimony, he predicted that across the world temperatures would rise dangerously due to human's increasing CO2 emissions.
As a result of the accelerating temperatures, Hansen foretold of major climate catastrophes that would plague the U.S. and the world within 20 some years, if business-as-usual CO2 emissions were not curtailed.
It's now 26 years later, and as the above graph depicts, global warming has stalled; CO2 emissions have not been curtailed in the least. And for the U.S. (look closely at the graph), continental temperatures actually experienced a cooling trend stretching over a decade.
The dramatic climate change disasters that NASA and Hansen predicted? Not even close to happening.
And those are the stubborn facts - much to the chagrin of the UN bureaucrats, national government elites and mainstream hacks journalists.

As decades of climate-doomsday cult 'AGW' propaganda have made abundantly clear, the world is supposedly endangered from rising human CO2 emissions...that produces a corresponding rapid and accelerarting global warming...which then results in CAGW hell for civilization...unfortunately for the IPCC (and alarmists), their own empirical evidence refutes the hypothesis and eviscerates the entire concept that CO2 is some sort of "control knob" thermostat for Mother Earth....
(click on chart to enlarge)
Simply stated, the climate reality facts do not bode well for those who still promulgate that Earth's environment is in 'crash & burn' mode from human CO2 emissions.
Whether it is the unanimous opinion by scientists regarding the 18-year "global warming" pause; or the last 9 years for the complete lack of major hurricanes; or the inexplicable and surprisingly thick Antarctic sea ice; or the boring global sea level rise that is a tiny fraction of coastal-swamping magnitude; or food crops exploding with record production; or multiple other climate signals - it is now blatantly obvious the current edition of the AGW hypothesis is highly suspect.
Not only is the AGW hypothesis invalidated by close to twenty years of empirical evidence, the CO2 as a "control knob" concept has been shed of any practical merit.
This has been discussed multiple times at 'C3' over recent years. Now, stepping back a few decades, during a 1988 Congressional staged testimony - conspiracy to mislead comes to mind - the top NASA climate expert predicted that 'business as usual' CO2 emissions would cause rapid and accelerated global warming.
Eventually, building on that 1988 performance, other climate experts developed a hypothesis that CO2 acted as the proverbial control-knob thermostat for the global temperature.
But in reality, is that even remotely accurate?
The above reality chart of empirical evidence affirms what the IPCC truly does not want to discuss: the "control-knob" concept is literally a myth.
The chart plots two-year temperature changes since 1988, with the respective two-year CO2 changes (ppm). It has been 26 years since that testimony-performance, thus there are 13 two-periods plotted on the chart. In addition, the linear trend for the HadCRUT4 gold-standard temperature dataset and NOAA's CO2 dataset are shown moving in opposite directions.
There is no doubt. The increasing CO2 changes are not producing the requisite increasing temperature changes, as predicted. Visually, the correlation between the two appears very lame, at best. The actual r2 is a meager 0.12 - yes, that's two plus decades of statistical nothingness.
Conclusion: Those stubborn climate facts are not kind to the ever-fading, CO2-induced global warming hypothesis. Climate change is always happening but it is highly unlikely that the miniscule trace-gas CO2 is a major driver (sure, a minor player, but not one that controls the world's fate). Time for policymakers to abandon the control-knob myth and instead focus on adaption preparation for all types of climate change.

Note: The chart plots and linear trends were created using Excel, and the HadCRUT4 dataset and NOAA CO2 dataset. The plots cover discrete two-year periods, starting with October 1988. The CO2 change is scaled to one-tenth of actual (so that temp changes are visually apparent). Hey, don't know how to chart the above in Excel? It's easy to produce charts - you can do it too!

The answers: Nope; Nope; Nope; Nope; and Nope...and the questions: "Does CO2 regulate global temperatures?"; "Does CO2 perform as global warming control knob?"; "Does CO2 act like the world's thermostat?"; "Does CO2 cause rapid and dangerous global warming?"; and, "Does CO2 produce accelerating global temps?" - the recent satellite empirical evidence provides the answers, much to the chagrin of the climate-doomsday cult proponents.....

This chart plots the global warming trends versus CO2 growth trends over a wide variety of time periods (last 30 years through the last 10 years, as of 10/31/2014).
As one can easily discern, while CO2 growth is exploding up, global temperature trends are collapsing over the same time.
In essence, the warming temperature trends have decelerated into cooling trends.
Visually, it is clear that modern CO2 growth has affected temperatures contrary to the predictions of the IPCC and AGW alarmists. In fact, the correlation between the CO2 and temp trends is negative.
Simply put, the trace gas CO2 does not regulate temperature; it does not act like a control knob or thermostat; and the greater growth in CO2 levels has not caused accelerated, dangerous warming.
Those are the stubborn facts. And it does not matter how many IPCC climate "experts" claim that CO2 is a 'control knob' or how many computer virtual simulations predict future dangerous temperatures based on CO2 being a 'regulator.' The climate reality of satellite empirical evidence falsifies those wildly speculative claims.
And it's not just the satellite empirical evidence that reveals the ongoing CO2/temperature disconnect.

Greenhouse gases, including CO2, looking less and less the major drivers of global temperatures and climate change.
When objective (non-IPCC) science research is done, without the political agenda, Earth's climate seems dominated by natural forces.
From 1950 to 1987 a strong relationship existed between the El Nino Southern Oscillation (ENSO) and HadCRUT4 global average temperature anomaly, interrupted occasionally by volcanic eruptions. After 1987 the relationship diverged, with temperature anomaly increasing more than expected, but was re-established after 1997 at an offset of ~0.48°C higher. The period of increased warming from 1987 to 1997 loosely coincided with the divergence of the global average temperature anomalies over land, which are derived from observation station recordings, and the global average anomalies in sea surface temperatures. Land-based temperatures averaged 0.04°C below sea temperatures for the period 1950 to 1987 but after 1997 averaged 0.41°C above sea temperatures. The increase in the global average temperature anomaly and the divergence of land and sea surface temperatures also coincided with two significant changes in global average cloud cover. Total cloud cover decreased during the period from 1987 to 1997 and, for most of the remainder of the period from 1984 to 2009, decreases in low-level cloud were accompanied by increases in middle and upper level cloud. These changes can be found in both global average cloud cover and in each of the six 30°C-latitude bands. The impact of these changes in cloud cover can account for the variations in HadCRUT4 global average temperature anomalies and the divergence between land and sea temperatures.
Climate change, as represented by global cooling and global warming trends, is in a constant flux...the IPCC's gold-standard temperature dataset provides the empirical proof that a natural cycle of ups and downs is the reality - past, present & future.....

How much global warming (or cooling) will take place by 2050AD?
The flat-out, scientific truth is that nobody really knows. Not the IPCC. Not the climate models. Not the experts. And certainly not the green crony-facilitators, Naomi Klein and Bill McKibben (fyi...crony Al Gore just loves them to death.)
This chart plotting the IPCC's gold-standard (HC4) of global temperature trends, of past and present, reveals why it is so incredibly difficult to predict climate change, be it of short or long-term nature. Climate change is constantly happening - going from one warming acceleration to the next cooling acceleration extreme, rather rapidly.
And note, this takes place regardless of atmospheric CO2 levels (see black curve), and associated human CO2 emissions. Clearly, the skyrocketing CO2 levels since the 1950's are not responsible for such wide variance in temperature trends, since they can even be observed a century before.
In fact, based on a visual inspection, one could surmise that climate change extreme trends have lessened since the modern increase of CO2 levels.
As can be seen, shorter cooling/warming trends have been highly variable from the very start of recording instrumentally-measured "global" temperatures. The light red (12-mth) and green (60-mth) plots readily show this.
So, when did the greatest acceleration of warming trends take place? Amazingly, all the warming spikes that matched or equaled ±20°C took place (see yellow-tinted boxes) prior to the last 40 years of massive human CO2 emissions.
Regarding the 10, 20 and 30-year climate change variability, there is no question that the wild and natural extremes of the short-term always return to a rather mundane long-term variability. The dark blue, cyan and bright red plots indicate long-term climate change that is...well...pretty mundane.
Compared to a 12-month climate change extreme trend of +25.0°C reached in 1878, the 30-year trend extreme only reached a maximum of +0.72°C (during 2003) and has now been reduced to a August 2014 30-year trend of 0.61°C - and relative to the 1940's, that's a trend only eight-hundredths of a degree greater.
Conclusion: Climate change never stops. Whether short-term or long-term, global temperature trends constantly accelerate/decelerate. Human CO2 emissions have nothing to do with this extreme variability - it is a natural phenomenon that is chaotic, totally unpredictable and unstoppable. The climate change indicated by today's temperature trends is insignificantly different than the past climate change. And those are the stubborn facts.
Note: Linear temperature trends do not represent predictions (any trend today can be drastically different in the future). Excel's slope function was used to calculate the moving trends for each time span (by month) and to plot them. To calculate the trends by 2050AD, the derived slope for each month and each time-span trend was multiplied by 424 months (after August 2014, there are only 424 full months until January 1, 2050AD). HadCRUT4 global dataset and CO2 (ppm) datasets used for chart can be found here.
Ahhh, those stubborn facts...it's now been two decades+ that the public has been warned about the existing dangerous and rapidly accelerating global temperatures...a warming that was supposed to produce catastrophic doomsday climate changes...except it hasn't happened, which the gold-standard of global surface temperatures document.....
(click on chart to enlarge)
Has two-decades worth of cumulative CO2 growth in the atmosphere caused the "experts'" predicted dangerous and rapidly accelerating global warming?
That's the straight-forward question.
And the straight-forward answer is?
Well, despite all that CO2 growth, global warming has slowed to a creep on the Earth's surface, and in the atmosphere, global warming has flat-lined.
Using the IPCC's gold-standard global surface dataset (the UK's HadCRUT4), this chart plots the cumulative growth in temperature along with NOAA's reported cumulative growth in atmospheric CO2 levels (ppm).
For CO2 (grey curve), there is a clear and consistent upward growth of CO2 levels - unrelenting would be an apt description. In contrast, global temperatures are all over the map, with highs and low being constantly...er, variable.
The end results over the 20 years ending August 2014 are fairly obvious:
The visual relationship between CO2 and global temperatures appears to be very weak; in fact, statistically the r2 is 0.19, which can be interpreted as being close to a zilch relationship.
Per both the 2nd order fitted trend (blue curve) and the 36-month moving average (red curve), the deceleration of the global warming trend and a plateauing can easily be seen.
Over the 20 years, there have been exceptional warm(-est!) months/years, often followed by exceptional cool months/years.
And since September 1994, the exhibited warming trend amounts to a measly increase of a non-doomsday +0.38°C by year 2050AD.
How easy is it to say, three times quickly?: catastrophe-climate-doomsday-cult-is-discredited.
So, does all the above empirical evidence mean that human CO2 has no impact on global temperatures? Nope. Does it mean the world will no longer warm? Does it mean humans don't have an impact on continuous natural climate change? Nope. Does it mean that the world should quit trying to be energy and carbon efficient? Not at all.
What it does mean, though, is that the public and the policymakers were greatly deceived by the "consensus" science and computer models that loudly declared (and btw, still do) imminent disasters and doomsday global warming.
As the current climate conditions now indicate a slow, creeping climate change scenario, it provides policymakers and the public the luxury of time to continue moving to a more carbon-efficient economy, thus improving the environment without needlessly sacrificing quality of life and living standards.
In summary, it's another case of those stubborn facts: the empirical evidence does not lie; but computer models and "experts" do.
Note: Download HC4 and CO2 datasets. Excel used to make calculations, trends and chart. The chart covers 240 monthly records, starting with Sept. 1994. For this graph, both the temperature and CO2 datapoints were set to zero; then the cumulative changes for both were plotted each month - does not affect linear trends when done this way.
We've been told by the climate experts that increases in atmospheric CO2 levels will cause Earth to warm rapidly and dangerously, to the point where civilization's existence was threatened...but what if these "experts" were completely wrong and there is actual empirical evidence to prove them wrong?....
(click on chart to enlarge)
Well, the NOAA empirical evidence from their global temperature dataset indicates that longer term changes in atmospheric CO2 levels are definitely not producing anywhere near the expected long-term changes in global temps, as predicted.
Indeed, "wrong" is likely an understatement.
As a result, the experts' CO2-induced CAGW IPCC hypothesis is revealed for its true nature - basically, a hypothetical nothing-burger.
Let's be clear: the actual NOAA empirical evidence, from the global temperature climate instrumental records, does not support the hypothesis that long-term changes in atmospheric CO2 levels produce rapid accelerating, dangerous global temperature changes.
The adjacent graph of 10-year CO2 change plots, and concurrent 10-year change in NOAA global temperatures, is unequivocal: there is no correlation between the two, unless one wants to argue that a r2 of 0.08 somehow indicates a strong relationship.
The chart includes a 60-month average (purple) curve of the 10-year temp changes; likewise there is a similar average curve (dark grey) for the 10-year CO2 changes. Obviously, these curves show no relationship and essentially are now moving in opposing directions. The purple curve (temps) reflects a pattern of climate ups and downs, while the grey curve (CO2) since 1960 suggests an exponential growth situation.
In addition, it has been noted on the chart when extreme 10-year temperature changes have taken place - those rare increasing/decreasing temp changes that equal or exceed +0.6/-0.6°C. There have been 8 such events, 6 of which took place prior to 1960 (see light-yellow boxes on chart).
Hmm...what's that you say?...growing human CO2 emissions have caused a greater frequency of extreme climate incidents during the modern era? Ahem...a definitive 'Nope!' will suffice at this point.
In summary, if long-term changes in atmospheric (ppm) CO2 levels caused long-term changes in global temperatures, then the chart would have plots of the two principal change datasets tracking each other - in reality though, they're demonstrably different.
The NOAA empirical evidence strongly undercuts the CAGW hypothesis and, btw, demonstrates for the related hypothesis (which states that CO2 acts as a climate thermostat/control knob) is laughable nonsense.
Does all of the above indicate that human emissions have zero influence of global temperature changes? In fact, it does not indicate that; instead, it indicates that the CAGW hypothesis is without factual merit and that the climate sensitivity to CO2 is likely significantly lower than the IPCC "experts" proposed.
With all that said, the data strongly suggest, at best, a rather trivial CO2-influence on longer-term temperature change and its being indisputably non-dangerous.
Note: Temperature dataset; CO2 datasets. Excel was used to calculate 10-yr changes (ie. differences); to calculate r2 using the slope 'correl' function; and to produce plots and 60-mth average curves. To calculate a 10-yr. temp. change example: subtract the August 2004 temp. anomaly from the August 2104 anomaly. The same subtraction method is used to calculate 10-yr. CO2 level (ppm) changes. Starting with January 1890, the 10-yr chg. calculations can be made for each subsequent month, resulting in 1,496 'decadal' datapoints (NOAA monthly dataset commences at January 1880).

Even the most die hard, green climate scientist who spouts CO2 catastrophe hysteria does not really believe in the unicorn of climate mythology - the mythical CO2 'control knob' - an anti-science myth pushed by the likes of Al Gore, Bill McKibben, Obama and scientist Leo DiCaprio...and there is a very substantial reason why scientists don't believe it...all the empirical evidence easily refutes its existence.....
(click on to enlarge)
Climate scientists who are not of the payroll of 'Big Green' NGOs, nor dependent on government research grants, find it much easier to speak out against the utter nonsense and myths of anti-CO2 activists and the slimy crony-greens.
An example: As climate scientist Judith Curry indicates, there is no basis for a magical 'knob' that would allow today's politicians and bureaucrats to dial-in a desired climate outcome for next month, or the next year, or the next decade, or the next century.
The facts, simply stated: There is no science, no computer model, nor any available mechanism(s) that would allow today's humans to tweak CO2 emissions a certain way in order to produce a future climate of specific attributes by, say, 2050.
It's what is referred to as, "no frakking way."
The inner circle of establishment climate science knows this, yet due to political agenda reasons, they are forced to deliver lip service to the ludicrous 'knob' analogies.
The massive failure of billion$ climate models and the ongoing 17+ year pause in global warming provide the necessary and vivid testimonials to the fallacy of a climate thermostat knob, whether controlling natural and/or human CO2 emissions.
In addition, there is the latest empirical evidence that completely invalidates the 'knob' assertion.
This adjacent plot of 5-year temperature change versus 5-year atmospheric CO2 level change is based on the most recent empirical evidence published by the government's GISS/NASA scientists (and they happen to be some of the largest proponents of chicken little global warming calamities).
This empirical science published by NASA is undeniable, and most alarmist scientists accept, although grudgingly - the relationship between changes in atmospheric CO2 levels and changes in temperature are, at best, significantly lame weak.
Indeed, the two dataset plots reveal zero relationship with a correlation that produces a r2 barely above zero. A non-existent relationship from 1880 to the end of August 2014,
Look at the green and red fitted trends. Obviously, the green CO2 trend exhibits rapid, accelerating and even exponential growth after 1950. And the global temps? The red temperature trend depicts very little growth in temperature change, and currently exhibits a deceleration that climate models and "experts" never predicted.
In fact, one could surmise that the temperature changes reflect a natural cycle of ups/downs (ie. a pattern), which the accelerating CO2 growth has absolutely zero influence on.
Ergo, the 'control knob' proposition has the same likelihood of reality as those space alien abductions one reads about, Big Foot enrolling at Univ. of Washington, Congress balancing the budget, or Earth developing a climate of "boiling" oceans.
Which is why at least 97% of actual climate scientists categorically reject this particular brand of Hollywood anti-science fantasy.
And yes, one can be a member of the 97% who believe humans have a warming influence on climate, and yet, still completely reject the existence of this particular mythical CO2 unicorn.
Note: Temperature dataset; CO2 datasets. Excel was used to calculate 5-yr changes (ie. differences); and to produce plots and 6th order polynomials. To calculate a 5-yr. temp. change example: subtract the August 2009 temp. anomaly from the August 2104 anomaly. The same subtraction method used to calculate 5-yr. CO2 level (ppm) changes. Starting with January 1885, the 5-yr chg. calculations can be made for each subsequent month (GISS/NASA monthly dataset commences at January 1880).
Climate "scientists" on the government dole claim that CO2 emission regulation will allow bureaucrats to tweak the world's climate...thus, "scientists" will provide the world's governing class with a means to "dial in" the Earth's desired temperature with a CO2 "climate control" knob...but as it turns out, it's an indisputable shiteload of fantasy bordering on delusional.....
(click on chart to enlarge)
Delusional fantasies? Pretty strong stuff one might say.
Oh well, let's review just six actual climate science facts to make the case.
===>First, we know that these same scientists don't even know where over 50% of CO2 emissions disappear to...
===>Second, we know (and these same scientists know) that the global temperature change response to CO2 has declined significantly - opposite of the IPCC's "consensus expert" predictions...
===>Third, we know that these same scientists have been predicting rapid, continuous, accelerating dangerous global warming for decades but it hasn't happened...
===>Fourth, since it is agreed by 97% of all climate scientists that global warming has essentially stopped for 17+ years (only the fringe quacks disavow this), these same bureaucrat/academia scientists have come up with an overflowing cornucopia of reasons why, which reveal absolutely zero consensus...
===>Fifth, we know that the $billion$ super computer climate models used by these same scientists are fatally flawed, thus absolutely worthless regarding future global and regional climate predictions...
===>Finally, as this accompanying chart of the empirical evidence indicates, while the per cent change in cumulative CO2 emissions dropped in a quasi-continuous pattern since 1979, the RSS annual global temperatures anomalies instead follow an opposite increasing trend.
Simply put, all the above scientific evidence falsifies the entire concept of a CO2 "control knob" for the world's climate.
Yet these on-the-dole scientists keep promoting this delusional, all-powerful climate "knob" fantasy at the major expense of not only the taxpayer pockets, but also the gargantuan expense of sound climate policy-making being derailed from the track of common sense and rationality.
Ahh...those stubborn facts just always seem to muck up the climate delusional dreams and nightmares of so many knob-fanatics and control-freaks.
Note: From this multiple dataset, an estimate of total human CO2 emissions from 1751 to 2013 can be calculated. Since the RSS satellite monthly dataset only goes back to 1979, the chart plots the annual per cent change in cumulative CO2 emissions since 1979 (starting with the calculated cumulative emissions from 1751-1979). The RSS plot represents the 12-month (year-end) average anomalies. Hey, don't know how to chart in Excel? It's easy to produce charts - you can do it too! Go here to learn how.
The climate science is indisputable...the known physics requires that each tonne of new CO2 emissions will have a smaller impact than the previous tonne...there is no escaping the actual logarithmic relationship between atmospheric CO2 and global warming.....
(click on to enlarge)
The known climate science of global warming is not a mystery. It is well documented climate physics that just about every scientist agrees with. And for the layperson, it's not terribly difficult to confirm.
3. A spreadsheet to make the necessary calculations and then plot the outcome.
These items were used to produce the adjacent chart. Five different time periods were chosen, then the warming (degree C) per CO2 tonne was calculated for each time period.
The resulting datapoints were then plotted and connected with a fitted trend (6th order).
Clearly, this actual climate science empirical evidence substantiates the known climate physics.
With this confirmation, one could assume that all warming since 1850 was due to human CO2 emissions, but then the logical conclusion is cast in concrete science - CO2's impact is shrinking towards zero, as observed, and likely will have even a smaller global warming impact in the future.
Note: The chart's fitted trend provides a sense of direction in the past but it has unreliable predictive qualities (if any). Why 1950-2013? Because the IPCC claims human CO2 is principal cause of warming since 1950. Why 1988-2013? Because in 1988, NASA's James Hansen testified that CO2 warming was accelerating and dangerous (it's been neither). Why 1997-2013? Because, it's been approximately 17 years with the 'paused' global warming. The 1850-2014 period assumes 17.5 gigatonnes of CO2 for first 7 months of 2014. Used 12-month HadCRUT averages to calculate deg/tonne.
For Democrats, green-fascists, liberals, leftists, progressives, socialists and all the various big government types, objective, non-agenda science is the enemy ... especially when it comes to climate science empirical evidence ... those stubborn facts can be sooo cruel.....

Adjacent are the top 5 reasons the global warming hysteria has failed.
They are called empirical evidence - datasets of temperature observations confirming there has been no statistically significant warming for over 15+ years.
The "consensus" "experts" and billion dollar computer climate models predicted that human CO2 emissions would generate accelerating, catastrophic global warming.
The 'climate panic' industry has long predicted that growth in atmospheric CO2 would produce rapid and dangerous global warming acceleration...but NASA's GISS climate research unit pretty much slams that alarmist myth to the mat with empirical evidence...
(click on chart to enlarge)
The CAGW global warming hypothesis is rather straightforward: increasing atmospheric CO2 would warm the world in an accelerating, out-of-control manner.
For the adjacent chart, that indeed would be the case, if we pretended the green curve represented global temperature and the red curve atmospheric CO2.
But it's just the opposite in reality.
As the chart depicts over 12 different time periods (all ending July 2014), reality is that while CO2 levels keep increasing over time, the long-term temperature warming trend (the red curve) is not rapidly accelerating towards a tipping point of climate catastrophe.
What about shorter-term? (Okay, okay we won't mention this inconvenient fact.)
Well, note the 3-year period mark. Over the last 3 years, the CO2 level has increased by 7ppm and the warming acceleration "spiked" at 3.8°C per century. To put that "acceleration" in historical context, during July 1915 the global warming trend had a real spike...a 15.4°C per century spike without any meaningful increase of CO2 over the prior 3 years.
Conclusion: It is clear from the NASA/GISS empirical evidence that warming acceleration trends are not highly correlated with ever greater atmospheric increases of CO2. The claimed CAGW impact from the growing accumulation of human CO2 emissions in the atmosphere appears to be temperature-trivial. From the evidence, one can also conclude that not even GISS can manufacture a temperature dataset that reveals runaway warming, let alone their fabled catastrophic "boiling oceans" prediction. Dang, those stubborn facts.
Note: Monthly GISS temperature dataset source. All chart time periods end as of July 2014. Used Excel to calculate trends utilizing the built-in slope function; plots created by Excel. Monthly CO2 levels estimated from a combination of source-1 and source-2. Interpreting the chart: for example, over the 60-year period ending July 2014, CO2 ppm increased by 86 and the GISS per century warming trend for the last 60 years was 1.3°C.
Obama and his ilk fervently believe the South Pole is melting, soon to drown America's coast lines with a rising sea level...or, maybe Democrats are just pathological liars determined to scare Americans into voting for even bigger government...regardless, both the scientists and satellites document how wrong the liberal-left-greens are.....

Science is based on research and empirical evidence, not on speculative guesses or those "likely" predictions from computer simulations.
Over the last few decades, the IPCC and its computer climate models have speculated that Antarctica was melting due to all the human CO2 emissions released into the atmosphere.
CO2 emissions that were producing accelerating and dangerous global warming that was being "amplified" across the South Pole.
Democrats, the mainstream media and green progressives have continuously repeated these flimsy, fear-mongering predictions as science "truth," representing the mythical "consensus." Yet, they conveniently ignore the actual hard empirical evidence and real scientific research that the American public has paid for.
Case in point:The South Pole
A brand new peer-reviewed research study conducted by MIT scientists confirm what NASA's satellites have documented (see adjacent chart) - Antarctica is cooling. Ahem...those inconvenient stubborn facts just hurt, no?
"By contrast, the eastern Antarctic and Antarctic plateau have cooled, primarily in summer, with warming over the Antarctic Peninsula [C3 Ed: approximately 4% of Antarctica land mass]...Moreover, sea-ice extent around Antarctica has modestly increased.....In other words, the authors find that most of the Antarctic continent has cooled, rather than just the Southern Ocean..."

A combination of fanatical green activists and wealthy crony-capitalists has produced a strong influence over the Obama administration and its climate policies/regulations ...Democrats in Congress have also been bought off...unfortunately for the American public, these corrupting motivations lead the government and bureaucrats down policy paths that ignore climate history and its science.....

"What's the weather tomorrow?" 'Been, there, done that'
"What will the climate be 10 years from now?" 'Been there, done that.'
Regardless of human activities and human CO2 emissions, the climate and weather have a strong, built-in natural rhythm that takes place, relentlessly.
The scientific evidence is unequivocal about this: the global climate repeats itself.
The adjacent chart plots the scientific empirical evidence - the globe naturally cycles through periods of extreme cooling and warming. And as the evidence reveals, the Obama/Kerry climate-porn duo exist during a period of cooling, not the extreme accelerating global warming that they claim.
For context, the chart extends back to the 1850s, with major peaks in the global warming trend identified with the president occupying the Oval Office at the time.
Note that the highest peaks (ie. dangerous and rapid global warming) took place prior to 1950 and the modern era's industrial/consumer CO2 emissions. Note also that after peaks were reached, the climate naturally repeated its cooling phase - every single freaking time.
And because presidents and Democrats during those times did not deny the natural cyclical peaks and valleys of the global climate, they did not end up making fools of themselves by claiming that CO2 'vapors' had given the world a fever from a runaway, tipping point warming.
By understanding the nature of the 'been there, done that' climate, past politicians did not hysterically succumb to the likes of today's anti-science charlatans advocating the deindustrialization of America, and the hypocritical snake-oil cronies wanting to steal from the American taxpayers' wallet.
Put another way, past politicians accepted those stubborn facts of empirical science, no matter how inconvenient.
Leftists, progressives, Democrats, liberals, socialists, crony-capitalists, communists, politicians, UN bureaucrats, crony-scientists, mainstream journalists and Hollywood celebrities are acknowledged as the world's climate-porn stars, as well as being in dire need of a basic manual titled 'Climate for Dummies'...their statements regarding global warming and climate change continue to be living proof that stuck-on-stupid and cluelessness are in a constant battle to dominate the leftward thinking brain.....
Without going through a complete litany of embarrassing and moronic left-wing climate change comments by the "elites," several from the past few weeks truly stand out:
===> "The planet is running a fever and there are no emergency rooms" - Democrat Senator Markey from Massachusetts
===>"We no longer need storms or hurricanes to produce flooding - it is becoming an everyday occurrence" - Anne Burchard, the Sierra Club
===> "It's kind of like telling a little girl who's trying to run across a busy street to catch a school bus to go for it, knowing there's a substantial chance that she'll be killed." - MIT professor Kerry Emanuel regarding critics of his opinion that catastrophic global warming disasters are today's climate
===> "It’s time for climate-change deniers to face reality’ – ‘They’re fiddling while the planet burns" - NY Daily News editorial page
===>"MSNBC segment claims that climate change could make a real ‘Sharknado’ happen" - a Comcast-owned Obama propaganda outlet
===>"And this, to me, is the most important film [Sharknado 2] ever made about climate change. There is no film, TV thing, special anything, more important than this film." - Actor, Judah Friedlander
===> "A new report says redheads might one day be extinct...when climate change brings an end to cool mist, the climate for red hair will also disappear." - Diane Sawyer, a TV "journalist", U.S. ABC News
===>"NYU Professor: Solve climate change by making people smaller" - S. Matthew Liao, instructor of bioethics at New York University
===>"Weather is not climate, you willfully ignorant fucksticks.” - obviously, the very "professional" CNN reporter, Bill Weir
Now, climate change comments like these have been part and parcel nonsense from the left-wing nutcases for over 100 years. As can be readily seen here, climate calamities are the 'forever' essential fear-mongering tactics used by elites and disaster-whσres to convince the public. (Additional crazed quotes from the "elites".)
More importantly, these common anti-science fear tactics are completely divorced from current climate science reality, as the empirical records demonstrate (here, here, here,here and here).
So, are the catastrophe rantings and hate emanating from liberal, progressive Democrats a result of some combination of incredible ignorance and stupendous stupidity regarding climate science?
If so, then maybe a book titled 'Climate for Dummies' would be a welcome science reading assignment for left-wing malnourished brains. Needless to say, said book should include a chapter on the science of temperature trends, made as simple as possible for those addicted to global warming calamity-porn.
Our contribution to the book will be the adjacent "Warming" Speedometer, which is a very simple visual aid to help liberal/progressive/Democrats put those really, really hard concepts of per century temperature trends into a proper context. (click on speedometer to enlarge)
For example, this simple decile infographic displays the entire range of 10-year global warming/cooling trends in per century terms since 1860. What could a climate-porn elite learn from this simple visual aid? (And help them from sounding like an uninformed idiot...)
the lowest per century trend (based on 120-month calculations) was reached during 1887
the highest per century trend was reached in 1983
the June 2014 per century trend falls into bottom half of deciles
the June 2014 trend is actually a global cooling trend
that some 31 years after the 1983 peak of 4.3°C warming trend, the temperature trend collapsed to a -0.1°C per century cooling trend.
Conclusions that a progressive/leftist elite might be able to reach from the simple "warming" speedometer of actual empirical evidence?
Hmm...let's see...that the approximate 1.5 trillion tonnes of human CO2 emissions (since the industrial age began) has not given Earth an accelerating fever that is causing the planet to burn - that's an unavoidable, rational and informed assessment of climate reality. And also that the world's modern climate, through June 2014, experienced a wide range of temperature trends (which are similar to the historical and ancient natural climate gyrations).
But as many have discovered to their dismay, empirical science means that liberal Democrats actually have to connect-the-dots, which apparently the climate-porn disorder prevents.

Climate change alarministas claim that modern human CO2 emissions are causing hotter temperatures around the world and the U.S...extreme global warming with blistering temperatures is their rallying cry but is it true?...Nope...it's another case of 'those stubborn facts'.....
(click on top or bottom chart to enlarge)
Of course, the CAGW argument has been (and continues to be) that huge CO2 emissions have produced extremely hot weather records during the 1980's, 90's and the 21st century, so far. But is it true?
Well, as pointed out earlier this year, the feared global warming is not producing the proclaimed hotter temperature records across the world.
And for the U.S.? NOAA confirms the same through June 2014. It is empirically true that the climate alarministas fear-mongering about record-setting extremes are without merit.
Case in point. This collection of charts depict NOAA's climate record frequency for maximum monthly temperatures across the contiguous U.S.
Figure #1 is the record of the 5% hottest months since 1980 in the U.S. Out of 409 months (34+ years), these 20 months represent the extreme. (The light blue data-points are the climate records since 1980 for all charts.)
Figure #2 is the 409-month record starting in 1920. These are the extreme 5% hottest months in the U.S. prior to the 1960s. (The dull red data-points are the climate records since 1920 for all charts.)
Figure #3 reveals that there have been zero months in the U.S. since 1980 that have had over 90 degree monthly averages. In contrast, the 1930's had two. In addition, for the period prior to 1980, there have been 57 months that averaged over 85 degrees while the period since 1980 there have been only 54.
Figure #4 plots the 60 hottest months for the two periods. Clearly, the pre-modern era produced hotter monthly records. These top 60 month plots represent the extreme 14.3% of each respective period.
For CO2 context, total global CO2 emissions are listed for each period (past and modern) on figures #1 and #2. The modern era emission tonnes are higher by a factor of 5+.
The evidence could not be clearer. Huge CO2 emissions, and higher atmospheric CO2 levels, do not correlate with a greater frequency of higher monthly maximum temperature records. This is indisputable.
Does this mean there won't be new record maximum temperatures set in the future? No, it does not. But, with that said, it is highly probable that future maximum records and their frequency have absolutely zero to do with greater CO2 emissions.

The frigid tropical hotspot continues to be a massive embarrassment to the CAGW faithful, and more importantly, the climate modelers...their prediction of a runaway tipping point in the atmosphere that would produce Venus-like temperatures is a classic example of herd-style failure by the consensus algorithms....
(click on chart to enlarge)
Two recent studies demonstrate the absolute futility of policymakers listening to climate modelers (and their billion dollar climate models) who continually predict climate calamities - a prediction record with zero successes.
The first peer reviewed study determines that today's climate models will never be able to predict the climate. Essentially, climate models assume linear climate relationships yet the real-world climate is non-linear and chaotic - defying intermediate and long-term predictive "expertise" with predictable regularity.
The second study clearly documents the abysmal prediction failure foisted on the public and politicians by the climate modelers. The climate models have long predicted a tropical hotspot in the atmosphere due to CO2 emissions; but actual scientific research reveals that the feared, mythical, runaway "tipping point" hotspot remains non-existent.
The hotspot tipping point, per the climate modelers, is supposedly in the process of turning Earth's atmosphere into a Venus replica, making Earth uninhabitable. But is that realistically happening?
The adjacent chart provides the indisputable, empirical evidence to answer that question unequivocally - NO!
The chart's red column is the Venus atmosphere's temperature at the 10km altitude. A conservative estimated temperature is still an incredibly hot 350°C.
In contrast, the chart's dark blueish columns show the Earth's atmosphere at the same altitude is an incredibly frigid temperature of minus 75C degrees. Yes, our tropical atmosphere is some 425 degrees colder.
Ahem....what freaking Venus-like tropical hotspot?! IT DOES NOT EXIST.
Of course, the climate moderlers stuck-on-stupid-Venus, don't mention this amazingly obvious climate fact. Instead, they focus on how Earth's tropical atomosphere is "accelerating" towards a Venus-like hotspot tipping point.
Accelerating? Barely creeping at a glacial pace would be more accurate.
Examine the chart closely. Since the beginning of the 1980's, humanity has poured some 860 billion CO2 tonnes into the atmosphere; atmospheric CO2 levels keep climbing (see yellow boxes); yet, the average tropical atmospheric temperature has essentially not budged (see red dotted baseline) over 3+ decades of modern consumer/industrial human emissions.
The solution to climate science reality and better policy? 'TRUST NO ONE CLIMATE MODEL' should be stamped on every CO2-centric climate model prediction and report that is handed to politicians and policymakers.
Then this type of anti-science insanity preached by the climate modelers would finally be D.O.A., never again to poison a public scientific debate with "runaway" catastrophic climate absurdities.
Note: Source of approximate 10km Venus temperature; source of approximate Earth's troposphere temperature; source of approximate tropical latitude troposphere temperatures; source of lower tropical atmosphere temperature change since 1979; source of total CO2 emission tonnes since 1979; source of peak CO2 ppm levels for each decade.
Per the empirical measurement evidence published by NASA, the last 15 years of temperature change is not much different than earlier, pre-modern climate change...tepid to lukewarm is about the most alarmist description that fits the CO2 doomsday-cult hysteria.....
(click on chart to enlarge)
As almost everyone (alarmists and skeptics) agrees, climate change is continuous, accompanied by associated temperature changes. Based on the common measurement techniques utilized, over the last two decades the globe has warmed.
However, with that said, the last 15 years of global warming has really not been too impressive - so unimpressive, that scientists are debatingspeculating what happened to it.
In fact, when examining the moving 15-year temperature changes over the last two decades, the NASA research indicates (despite the gigantic modern human CO2 emissions) that pre-1950 global temperature changes were greater.
Yes, you read that right. When examining absolute 15-year changes in temperature, our modern warming doesn't quite measure-up to earlier warming.
The adjacent chart plots 15-year (180-month) absolute temperature changes (i.e. differences) of the two decades 1924-1944 (starting July 1924, ending June 1944); and plots the 180-month temperature changes of the two decades from July 1994 to June 2014.
As the chart indicates, both periods have similarities, but the greatest long-term global warming took place prior to 1950. The linear trends on the charts denote the continuing acceleration of 15-year warming (red straight line) for the pre-1950 era, versus the decelerating trend of our current times (green straight line), as reported by NASA scientists.
And, as can be observed, both the long-term warming and cooling extremes were greater during the pre-1950 decades. Confirming the pre-1950 weather/climate extremes is rather easy - just read the headlines from that era.
Conclusion: Modern climate and temperature change is somewhat tepid when compared to the natural extreme changes during the 1930s and 1940s. It would seem that human CO2 emissions are not causing unprecedented, accelerating extremes in modern weather and climate over recent 15-year spans, and may actually be dampening the extremes when compared to the past.
Note: The above chart is comparing the 2 decades ending June 1944 versus the 2 decades ending June 2014 - both periods exhibit identifiable warming.

The over-the-top predictions of catastrophic climate disaster from proponents of CAGW have become a public relations disaster for the establishment science community...the constant hyperbole about extreme climate change due to abrupt, accelerating and unequivocal global warming turns out to be without empirical, scientific merit, as the UK's recognized gold-standard global temperature dataset confirms....
(click on image to enlarge)
The lack of major hurricanes making direct landfall on the continental U.S. over the last 8+ years is a classic example of extreme climate change not happening as predicted.
Now, add to that the complete disappearance of statistically significant global warming - for the UK's HadCRUT4 there has been no statistically significant warming since October 1996; and for the RSS global atmosphere dataset, it has been since November 1992 - and one then begins to wonder about the incompetence of elite science.
The absence of climate significant warming by itself pretty much confirms that extreme climate change is a non-issue, deserving little priority and resources.
But, there is another view of extreme climate change that can be examined to ascertain whether it has become a modern era problem or not. This can be accomplished by examining simple 10-year absolute change events for global temperatures, both positive and negative.
By identifying the largest 20 warming events and 20 largest cooling events since 1850, the most extreme 2% of temperature swings can be placed in chronological significance. (This identification is best done with the IPCC's gold-standard, the UK's HadCRUT4 monthly dataset, which stretches back to 1850.)
The charts above provide the identification of these extreme, outlier temperature swings. (The May 2014 HC4 dataset contains 1,973 monthly observations from which 1,853 moving 10-year absolute change calculations can be derived.)
As is evident from the empirical data, the vast majority of extreme temperature swings (both warming and cooling) occur prior to 1960. Also, the charts' purple linear trend lines indicate that the extremes are shrinking (getting smaller, if you prefer) over time.
Conclusion: Human CO2 emissions have not caused the predicted abrupt, accelerating and unequivocal global warming during the modern era, as all of the above scientific evidence attests. In addition, the lack of extreme climate change disasters and shrinking temperature swings, in relation to the past, actually indicate there may be an inverse relationship with growing CO2 emissions and atmospheric levels.
Now that would truly be mind-boggling, and help explain why "consensus" scientists are so befuddled and at a loss. Of course, stranger things have happened, such as the recent admission by consensus establishment science that they have been horribly wrong (for three decades, yikes!) about dietary cholesterol and saturated fat causing heart disease.
However, with all the above stated, this does not mean that climate change is not happening; that human activities have no influence on weather and climate; nor that global warming won't occur in the near future.

Are humans turning Earth into another Venus, an inhabitable planet with temperatures hotter than your Weber grill on the 4th of July? Well...when the empirical dots are connected the scary Venus fate for Earth goes poof....
(click on chart to enlarge)
In a previous post, empirical observations documented the lack of both short-term and long-term warming of the atmosphere.
Another approach to assessing the atmosphere's temperature change is to examine the 10-year changes in the lower troposphere. The graph on the left plots such changes.
Using a satellite dataset that contains 426 monthly temperature measurements, 306 moving 10-year changes can be calculated. This graph plots those 306 data-points (the proverbial 'dots'), plus the cumulative growth in CO2 levels over the same period.
Visually, it is obvious the 10-year temperature changes were dominated by increasing values up till the early 2000's. After that, the 10-year changes decreased consistently, turning from positive to negative. The graph depicts the global atmosphere actually cooling over recent time.
The long increase in 10-year temperature change, and then its subsequent decrease, is confirmed by both the 3-year simple average curve (aqua) and the fitted trend curve (6th order polynomial).
The pale green curve (another fitted trend curve, 6th order) represents the unabated, relentless cumulative growth of atmospheric CO2 levels.
Conclusion: Earth is not turning into Venus. The experts' predictions that human CO2 emissions would turn Earth's atmosphere into a simmering Venus lookalike, resulting in "boiling" oceans, is now substantiated as a crackpot, global warming bogosity - pure anti-science alarmism that was promulgated by establishment science.
Does the above mean that Earth's atmosphere will never warm again? Nope, it will indeed continue to have phases of warming and cooling just as it did in the past, sans Venus conditions, though.....because that is what climates do, just naturally.
