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.
This chart depicts historical precipitation and temperature reconstruction from northern China.
Overlaid on the chart by 'C3' are significant Chinese events from the past, along with identification of major solar states (minimums and maximums).
The scientists who compiled the precipitation/temperature records and produced the reconstructions had summarized that solar influence was climatically significant for China due to the affect on annual monsoons.
Using Wikipedia, major war/violence/political events were identified and then added to the chart (color bars).
To the more than casual viewer, it would certainly appear that a cooler climate regime has a higher association with extreme organized violence than a warmer period.
The chart's green curve indicates that those periods with less precipitation (i.e. droughts) are more common when cooler temps prevail - more arid conditions, with less food production make people (and societies) rather restless.
The unequivocal and indisputable climate research clearly demonstrates that climate change is constant; and when combined with historical accounts and anecdotal evidence, warmer climates tend to favor prosperity and peace outcomes while cooler periods provide more of the opposite.
Note: 'C3' originally wrote about this research in 2011. There was a recent article at Ice Age Now (and a YouTube video) using another 'C3' chart with significant Chinese events being overlaid on the Greenland ice core temp reconstructions (that prompted our doing the same for the above northern China chart).

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.
As the U.S. East Coast continues to dig out from another major blizzard, it is a reminder that natural climate forces and patterns have eviscerated the predictions made by by government climate "experts." Their predictions of warmer winters and less snow have not only been incorrect, they have been flat-out spectacularly wrong.
While ignorance is bliss for many, it is still is no excuse for the elites of politics and media to continue to spread falsehoods about CO2 causing warming winters.
As the above NOAA graphs clearly document, the strong cooling trend for the winter months of December (19 years), January (21 years) and February (20 years) across the U.S. northeast is indisputable.
Let's be clear about this: there is no identifiable group of climate-doomsday experts within government-funded circles who predicted twenty years ago that CO2 would cause this cooling trend outcome.
And precipitation trends over the same time periods in the Northeast? Well, depending on the month, take your pick, up or down. For any given winter month, one year of cold temperatures could produce a wet or a dry month.
It would appear that winter weather is not that predictable from year to year; and obviously, nor are climate conditions some 10, 20 30 or 50 years into the future.
Those who have relied on the CO2-induced AGW climate hypothesis have continuously been proven wrong. Yet, the CO2 cult faithful still hold climate doomsday predictions as gospel, regardless of the empirical science.
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:
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.
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.
Additional modern temperature charts.
Note: Trends of the past are not reliable predictors of future.
Very, very not likely, as it turns out.
As the adjacent chart shows, the reported 2014 HadCRUT4 (HC4) global temperature with its estimated error bars (±0.1°C) may have been the warmest, and then again.....there are 15 prior years that may have been warmer when considering all the error bar implications.
To add another consideration to the analysis, why should one blindly accept that the margin of error is only ±0.1°C?
Maybe it's time for both the policymakers and public to recognize that the margin of error should be at least ±0.2°C for global temperatures, as reported by the major climate agencies.
As a numerous experts are discovering, and clearly documenting, the major climate research agencies have been practicing a wholesale change (i.e. adjusting, manipulating, fabricating, etc.) of the reported empirical measurements. The result? The recent global surface temperature datasets are now much warmer than originally reported.
And it is not difficult for the non-government climate science experts to identify locations across the globe where temperatures have been "adjusted" up well past the supposed margin error upside of +0.1°C.
This means that the commonly used margin of error as currently applied does not take into consideration the plethora of recent questionable manipulations to make the world "warmer." Put another way: the margin of error does not account for the identified 'scientist-caused' global warming.
Case in point.
During early 2014, the MetOffice replaced the world's gold-standard HadCRUT3 (HC3) global temp dataset with their new HC4. When one applies the more probable ±0.2°C error range to the cooler HC3 dataset, the result is that there are actual years during the decade of the 1970's that would have matched the 2014 HC3 reported temp; and multiple years of the 80's that would have exceeded.
Conclusion: From a variety of measurement tools, it is known that the world has warmed overall since the 1970s. It is now indisputable that the MetOffice/NASA/NOAA surface temperature datasets have "mysteriously" and significantly diverged from the satellite temperature measurements that they so well matched in the past. It is also well established that the surface datasets are constantly being adjusted upward on a frequent basis. Because of these questionable adjustments, the commonly used margin of error is most likely too narrow. In order to compensate for these human endeavors to enhance the "global warming" storyline, the margin of error range applied by policymakers should at least be doubled, if not more.
This is not brain surgery. This is not rocket science. This is not nuclear physics.
This is climate science fact versus climate science fiction (i.e. computer model simulations).
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.
Article source for above climate model predictions.
Ocean expert Bob Tisdale's recent article delineated the various warming trends of the key ocean basins.
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.
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.
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.
Note: Source for Canadian hottest temperatures - just some more of those inconvenient climate stubborn facts.
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.
Note: NASA/GISS dataset used for Excel chart.
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.
Note: Excel used with this dataset to calculate then plot year averages.
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.]
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.
Per the Real Science climate site, this NOAA chart shows why the 'hottest-evah' did not happen in 2014.
Simply, well over half of the U.S. experienced cooler temperatures than normal.
And the warmer temperatures out west were more likely the result of an El Nino brewing than due to human CO2 emissions.
As this map suggests, CO2-caused "global" warming is highly suspect since normal regional weather/climate oscillations easily overwhelm its impact.
And as the satellites report, global warming over the last 18 years is not what one would call 'robust.'
#tcot #gop #agw
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.
Source for U.S. temperature regional temperature trends.
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.
Double bonus if that expert also predicted this.

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!
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.
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).
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.

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.
Note: UK CET monthly temperature dataset can be downloaded from here. CET provides absolute temperatures and these can be converted to anomalies using a 1901-2000 baseline averages that can be readily calculated. The 1901-2000 baseline was chosen since previous article about US temps used that baseline. Plots, averages and trends produced by Excel.

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.
Note: US temperature dataset can be downloaded from here. NOAA/NCDC reports absolute temperatures and these can be converted to anomalies using the 1901-2000 baseline averages that NOAA provides.
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! Go here to learn how.
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.

Well...er...be happy, unless the long-term global temperature deceleration continues into a miserable and dangerous global cooling situation...as the GISS (NASA) empirical evidence indicates, CO2-caused "catastrophic" global warming is an absolute non-issue..... (click on below chart to enlarge)
Yes, one gets the above two charts, revealing interesting, empirical climate science truths, such as:
1. The chart on the left (for periods ending Sept. 1999) reveals an acceleration of global warming trends, while the CO2 growth trends (see black dotted curve) across periods were fairly stable.
2. The chart on the right (for periods ending Sept. 2014) reveals a deceleration of global temperature change that over the 'last 10 years' reached a very slight global cooling status; yet, as can be seen, the CO2 growth trend was accelerating, reaching a rate robustly greater than those periods ending in 1999.
3. Other than a single datapoint (blue column), all the long-term temperature trends for the left chart exhibit warming greater than 1.5 degrees per century; in contrast, the majority of trends (blue columns) for the right chart are below 1.5 degree per century, despite faster CO2 growth and the associated higher atmospheric CO2 levels.
4. Rapid, dangerous, scary, undeniable, indisputable, irreversible, accelerating and catastrophic global warming claims made by various politicians, scientists, bureaucrats, celebrities and "journalists" are unequivocal lies. Long-term global temperature trends below 2 degrees (and going lower) are clearly the opposite of those widely-used, deceptive descriptors.
5. If it was not obvious before, CO2 is not a global "control knob" nor some type of "planet thermostat" - CO2 does not have much, if any, influence on temperature trends.
6. Confirming what climate skeptics (often called "deniers" for denigration purposes) have been stating for the last several decades, the climate changes constantly, primarily from natural forces. As a result, global temperature trends change frequently, exhibiting both cooling and warming modes across time spans.
We call it 'natural' climate change and ancient and historical climate records are replete with it. It happens often and, my goodness, it can be really extreme.
Now some caveats. The charts display a wide variety of temperature trends - they are not predictions for the future. They represent a snapshot in time and can change quickly.
One cannot conclude from the right chart that global temperatures will continue to decelerate into a glacial freezer. That would be exactly the same mistake that the climate "experts" made with the chart on the left - concluding that the temperature trends would just keep accelerating until hellish warmth would end-civilization-as-we-know-it.
And, these two charts cannot be used to claim that humans have no influence on global temperatures. Besides emissions of greenhouse gases, humans are constantly changing their environment which does have an impact (e.g. turning a corn field into an asphalt parking lot or massive deforestation in the world's major tropical rainforests or laying down a carpet of black soot on ice sheets).
Putting aside any further caveats, as an added bonus, the charts can be used to identify climate-liars. These are personalities and organizations that would never publish temperature charts as seen here. Instead, they resort to visual or verbal representations that today, or this month, or this year was the 'warmest' ever. This is not only the worst kind of cherry-picking, it is also incredibly lame.
Since the Little Ice Age (LIA), the world has been warming. It will continue to do so. Thus, we are going to keep experiencing warm(er) and warm(est) events - it's a no-brainer due to natural warming rebound. It will only stop happening when the world enters another mini ice age or worse. Those are the stubborn facts, which essentially makes CO2's trivial influence irrelevant.
When one hears the 'warmest' or 'warmer' refrains, that is when it becomes apparent one is in the company of a climate deception-meister.
Finally, let's all hope the global temperature deceleration shown on the right-most chart stops before it gets really ugly.
Note: Temperature dataset and CO2 dataset used to produce Excel charts and 2nd order fitted trend of the trends. Excel's slope function was used to caluclate each period's trend, then multipled by 1200 to produce a per century trend. Hey, don't know how to chart in Excel?

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.
By year 2050, how much warmer will it be?
As the climate "experts" and $billion$ computer models have proven decisively, they are completely clueless when it comes to predicting future global temperatures.
Fifteen years ago, this graph's red curve, representing temperature trends, was tracking right along with the CO2 grey curve - such that, as of the end of September 1999, the 10-year temp trend was on a 2050AD warming pace of +1.1ºC.
But as the adjacent chart now reveals, by end of September 2014, that previous +1.1ºC trend has changed to a -0.03ºC cooling trend despite the continuous acceleration of atmospheric CO2 levels. A powerful testament to the overwhelming significance of natural climate change that far exceeds the influence of of a trace gas such as CO2.
And remember, not a single IPCC or NASA/GISS "expert" predicted this outcome - just the opposite in fact.
As the graph's red plot depicts, global warming trends have been on a deceleration path for an extended period, indicating a strong likelihood that global warming by 2050 will be nowhere close to he current official predictions.
Did we mention 'pussy cat' warming yet?
Obviously, the "settled" science of slam-dunk global warming is in shambles. And natural climate change made it so, much to the chagrin of those elites pushing "consensus" anthropogenic dogma.
Without doubt, in the scheme of urgent, priority issues facing the nation - global warming ain't one of them, which the American public already knows and reflects.
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.
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:
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.
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).

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.
Additional temperature and climate charts.
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).
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.
To do so, one needs the following:
1. A global temperature dataset
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.
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.
But it hasn't happened - ooops!
Note: Atmosphere datasets (RSS & UAH); Global datasets (HadCRUT4 & NASA/GISS); Ocean dataset (HadSST3)
All politicians, bureaucrats and scientists are prone to ludicrous exaggerations, lame mistruths and outright lies as techniques to frighten and push the general public towards accepting an agenda...and leftists, socialists, marxists, progressives and liberals are really exceptional talents in this art of public deception...some very recent climate-liar examples:
"Climate change is the most consequential, urgent, sweeping collection of challenges we face" (Hillary Clinton)..."confronting climate change” is “a duty or responsibility laid down in scriptures" (John Kerry)...“Climate change is so much more consequential than ISIS ever was" (Leading Democrat consultant)...“we are not very far” from the point where climate change should be declared an international public health emergency" (UN's Christiana Figueres).....
Any political success that is achieved by deceit, hyperbole and hysteria always requires a sacrifice of the empirical evidence and unbiased science.
Yet it is scientific facts and methodologies that ultimately win...it follows that the public can only be mislead for so long.
Despite the extremist hyperbole and doomsday-cult scenario hysteria, the science of climate change is rather mundane, from a long-term view: it gets cold and, OMG!, then it gets hot, with some periods of in-between. Climate change is constantly in play; and humans can no more stop its chaotic version of ebbs and flows, let alone ever controlling a single cloud, thunderstorm, hurricane or tornado.
This chart, from the science journal New Scientist, is a prime exhibit of real-world scientific evidence that reveals how inconsequential today's climate change is compared to all previous climate change.
From the chart, it is clear that extreme climate change is a constant; there have been much higher and lower temperatures in the past; modern climate temperatures are not excessive in the least; and, the purported human-induced, "dangerous" modern temperature warming is only a fraction of past natural increases.
We say purported, because our existence is taking place during a global cooling phase (look at chart closely and note the pale blue areas) which is rather long-in-the-tooth, and at some point would normally rebound to warmer temperatures, just naturally. Indeed, the entire warming since the Little Ice Age is likely to be predominantly a natural response to the prior millenniums of extended cooling.
As the chart's inset clarifies, the modern warming since the end of 1949 has been very modest, being completely within the bounds of previous ancient and geological warmings that have been identified by empirical science.
And the "tipping point" warming has become even more modest during the 21st century:
Note: Added the red and blue lines to above New Science chart. The added lines represent the HadCRUT4 global 60-month average temperatures at December 1855, December 1949 and July 2014.
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.
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.
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..."
Update: Go To Top 40 Reason List
In attempts to solve this science mystery, climate scientists have developed multiple hypotheses to explain this phenomenon.
Yep, their explanations are now up to 30...okay, maybe it's 29, plus one the climate alarmistas are currently testing on mainstream journalists.
Well, so much for 97% consensus of climate science, eh?
To the left, the current 'hiatus' hypothesis list is summarized.
Original top ten list here.
Note: #28 and #29 on list mention names of WUWT contributors (lame inside joke for WUWT regular readers).
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.....

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".)
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...)
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.

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.
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 debating speculating 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.
Additional modern and regional temperature charts.

As the above paragraph suggests, it's easy to throw out rhetorical bombast in response to over-the-top CAGW doomsday B.S. - especially if the bombast is directed at wealthy elites' galactically-sized hypocrisy and crony-capitalist climate change endeavors.
By now, per the recent polling of Americans (here and here), you'd guess that the GWNs would finally forsake the rhetorical excesses as being a spectacular failed public relations campaign, but apparently not, if the NY Daily News is any indication.
Putting the bombast aside, let's continue with the analysis of those inconvenient global warming and climate change facts.
Recently, 'C3' published a few articles about the actual temperature change experienced across the globe. The key word is 'change.'
When specific temperature 'change' is examined, does it exhibit characteristics deserving of the establishment elites' commonly used fear-mongering qualifiers? Those are qualifiers meant to scare purposefully, such as: accelerating, abrupt, unequivocal, irreversible, rapid, dangerous, indisputable, irrefutable, incontrovertible and etc. Or, as in the case of the wordy wordsmith elites at the NY Daily News, "while the planet burns."
The above chart on the left (Fig. A) is from this 'C3' article, which examines the 6-month absolute temperature changes derived from the state-of-the-art satellite measurement technology. Clearly, the empirical 6-month temperature changes since 1979 do not exhibit characteristics equal to the fear-monger qualifiers, let alone the hysterical, anti-science bullshît of "planet burning."
But wait.....what if the planet really was burning, per the elites' propaganda? What would accelerating, dangerous and unequivocal temperature change look like?
Well, that would be the fabricated 6-month change chart on the right (Fig. B). Using the same time period since 1979, the temperature changes plotted represent the simulated monthly temperature anomalies increasing every single month by just a tiny amount. As a result, the 6-month temperature change curve becomes a fevered-planet exponential.
That's the face of frightening global warming - an exponential precursor to the figurative "burning planet." But the real world intrudes as Fig. A is not that precursor - NOT EVEN CLOSE.
(Tip: If the actual climate temperatures ever produced a similar exponential 6-month, or a 36-month, a 60-month, a 120-month or a 180-month temperature change chart as Fig. B, then it's time for all good skeptics to move their petro-dollar funded haciendas to tropical Antarctica.)
Now, obviously, the two above charts look entirely different. And if the climate is producing accelerating, abrupt, unequivocal, irreversible, rapid, dangerous, indisputable, irrefutable and incontrovertible global warming (i.e. "planet burning") then the 6-month change chart on the right would be reality.
But the chart on the right is not reality - the chart on the left is, which presents a fairly constant up/down of temperature change, essentially negating opposing extremes. That's how the natural climate works in regards to both short-term and long-term temperature changes.
BTW, speaking of lack of extremes...to reinforce what climate reality truly is, depending on your preferred temperature dataset, there has been a non-extreme, slight global cooling trend, from a minimum of 9+ years to 17+ years . This is not some hidden science artifact that only the climate guru-clerics know about. This has been widely discussed in peer-reviewed journals and blogs for the last few years.
Despite the overwhelming empirical evidence, the establishment's elites and mainstream media continue to publish "burning planet" falsehoods. Being completely divorced from the known climate science facts has (thank goodness) seriously undercut their credibility and trustworthiness.
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.
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.
Note: UK's HadCRUT4 2014 satellite dataset used in Excel to calculate 10-year absolute (i.e. arithmetic difference) temperature changes and linear trends for above charts. 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.
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.
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.

It has been predicted by the climate "experts" that human CO2 emissions would cause the world's atmosphere to warm dangerously, producing catastrophic, world-ending climate disasters.
Some 30+ years later, the advanced satellites circling the globe, 24/7, provide the empirical evidence that the "expert" predictions were of no substance, nor merit.
The adjoining graph is a plot of short-term temperature changes since 1979, along with the cumulative growth of atmospheric CO2 levels. Specifically, the 6-month temperature changes show little, if any, impact from the continuous growth of the atmospheric trace gas, CO2. [Clarification: chart's temperature plot is a moving, full 6-month temperature difference calculated from global RSS monthly anomalies, currently 426 anomalies in dataset]
In fact, the overall trend (aqua line) of 6-month changes is actually negative - an indication that abrupt, accelerating dangerous global warming of the atmosphere is non-existent. [Clarification: Aqua line is a linear trend produced by Excel]
Now, that is the short-term. What about the long-term?
A recent study by a group of pro-catastrophic global warming scientists1 determined that the human CO2 warming influence on atmosphere temperatures would be obvious over 17-years of satellite measurements. These are the scientists who claim we have experienced catastrophic global warming, with world climate disasters being imminent.
And what has happened, over this long-term span specified by these scientists?
Over the last 204 months (that's 17 years through June 2014), the atmosphere temperatures have actually exhibited a global cooling trend, not warming. The per century trend is only a -0.36°C. Despite this small number, it still represents a cooling trend, opposite of consensus predictions.
Whether short or long-term, the state-of-the-art empirical satellite evidence is not only obvious, it is both climate and statistically significant: CO2 emissions have not had a significant influence (warming or cooling) on atmospheric temperatures. For objective science, this means that the CO2-centric anthropogenic global warming hypothesis is essentially invalidated, as it is currently understood.

Regarding claims of "irreversible" and "accelerating" global warming, the scientific empirical evidence (analysis of monthly measurements) comparisons is indisputable: over the last 15+ years, global warming has gone AWOL, which the climate "experts" are mystified about.
Ergo, modern global warming has been in a non-accelerating state, a status reversal taking place since the late 1990's.
Here and here, the scientific evidence from NOAA, when analyzed from a 5-year climate change viewpoint, clearly shows that both modern U.S. and world-wide warming are not "unprecedented" when compared to earlier 20th century periods.
Moving on to a different perspective, the adjacent chart documents that modern atmospheric CO2 levels growth was approximately 6 times greater than during that of the pre-1950 period.
Yet, this immense growth of modern emissions barely produced an uptick in 10-year global warming averages, when compared to a similar time span for the pre-1950s. This is the undeniable result of an analysis of the UK's HadCRUT4 global climate record dataset.
The difference between the two period's 10-year average increase was a trivial +0.1°C - that's well within the range of what natural climate variation could explain. If HadCRUT3 datapoints were used instead, the difference shrinks to +0.05°C.
These differences are meaningless; of no material, meaningful climate consequence; and, totally undeserving of the label "unprecedented."

Recently, the White House released their U.S. climate assessment report that was shockingly deceptive - contrary to NOAA's own empirical climate evidence that is widely available.
Many of the mainstream press outlets, acting as this administration's propaganda instruments, reported the deceptions as is, even sometimes enhanced with their own climate-doomsday embellishments.
The major deception of the climate report is the falsehood that accelerating U.S. and global warming is taking place due to human CO2 emissions.
It is important to note that the science journals, and even some mainstream media outlets, are actually reporting the facts that the globe's predicted, unequivocal warming has stalled for over 15+ years.
This is also true for the continental U.S. temperatures during the 21st century, though, with an obvious difference. As the adjacent chart reveals, the U.S. temperatures exhibit an actual cooling trend - actually opposite of the rapid, dangerous, "scorching" climate that the White House and some propagandists liars journalists report.
Based on moving 5-year averages of U.S. monthly temperature anomalies, America's continental climate is currently cooling at a minus 1.2°F per century rate.
It's just another case of 'those stubborn facts' being mighty inconvenient.

Actual climate science and empirical evidence has long been the enemy of the green/left/Democrat consortium being funded by Obama's crony-donor billionaire friends. A classic example of their littering the editing floor with scientific truth can be found in this recent Mother Jones article.
The top/left 'image #1' comes straight from the 'MJ' article and it immediately sets off one's B.S. detector.
Vast portions of the U.S. have just made it through a brutal winter and a cold, wet spring, yet Mother Jones is talking global warming "scorching"? In fact, after 30 years of gigantic CO2 emissions, the first four months of 2014 temperatures in the U.S. were, on average, -0.26 degree lower than those of January, February, March and April during 1984.
Yep, 30 years later the U.S. was cooler - as pseudo-journalist Chris Mooney would say: "It's about our scarcely recognizable present"
In determining where this Mother Jones pile of B.S. was leading, a closer scrutiny of the 'image #1' reveals that it is a temperature map for the last 22 years.
Whoa, 22 years!? WTF?
Honestly, what objective, impartial person interested in the empirical-based science would pick a 22-year snapshot as the sole climate representation of the U.S. with no other context? What major publication would publish such a temperature map without at least also showing what has happened to U.S temperatures since 1996?
Can you quickly say "amazingly, ludicrous, cherry-picking misinformation" three times in a row? It's safe to say Chris Mooney and Mother Jones can.
So, what would cause those brainy "elites," who suffer from an obvious CGWDS affliction, to basically misrepresent the climate as it is being experienced today, but instead focus on a specific 22-year period? Why not present the readers with multiple-period maps and graphs that provides a contextual full picture of reality?
Well, image #2 (top/right) provides the ready answer to their ludicrous cherry-picking deception.
Turns out that the 22-year period ending March 2014 had the highest per century rate of U.S. warming when analyzing multiple time periods. Yet, as the American public is well aware, the previous U.S. warming trend that generated that unique 22-year peak has since morphed into a cooling phase since 1996 - ahem...now look at all those negative blue bars in image #2 starting with the last 18 years.
Adding even more proof that the U.S. is not suffering from "scorching" global warming deception, images #3 and #4 reveal NOAA's climate reality for 1992 (22 years ago) and 2014, respectively.
How about that! NOAA, the principal U.S. climate research agency, reports that the U.S. recently experienced an actual cooler climate than that of 1992 (22 years ago).
Gee, why would Chris Mooney and Mother Jones leave important empirical evidence context like this out of their "scorching" article? Hmmm...makes one wonder if they purposefully want their readers to think they are liars; or maybe they think the readers of 'MJ' are just incredibly gullible and/or common sense stupid. Who knows?
Oh...and those "Seven Scary Facts About The Global Left & Greens":
1. they start with the initial bullshÎt;
2. then they sprinkle some more bullshÎt here and there and everywhere;
3. they advance their agenda by rapidly accelerating the bullshÎt spreading with over-the-top hyperbole;
4. they then deny their bullshÎttÎng when all the scary predictions fail;
5. then they claim they were misunderstood and really did not mean their previous bullshÎt to be literal;
6. they then introduce multiple new theories as to why some new bullshÎt should be believed, ignoring the fact all their previous bullshÎt was completely wrong;
and #7, hey, they finally state that you're a racist, Gaia-hating, homophobic, paid-by-the-Koch-brothers denier if you no longer believe all of their anti-science, doomsday bullshÎt.
Climate reality and actual evidence-based science has completely eviscerated the global warming claims of the IPCC's "scientists" and those in the "consensus" choir.
Recent climate change predictions produced by the latest bleeding-edge computer models have proven to be spectacularly wrong.
Longer-term proof that the IPCC (and its climate-doomsday religion acolytes) is provided by the original "expert" predictions that were first published back in 1990. That proof is clearly obvious from the accompanying chart.
Simply stated: the IPCC predicted that if human emissions of CO2 kept growing in a business-as-usual (BAU) manner, the world would experience a high likelihood of global warming acceleration - to a per century rate of 2.8°C.
Instead, as the chart depicts, global warming since 1990 has achieved only a 1.4°C per century rate, per the global-wide 24/7 measurements of satellites. Yet the BAU growth of human emission tonnes actually accelerated to a 13.2% annual rate for the 10 years ending 2013. Those are the stubborn facts that are indisputable, unequivocal and irrefutable.
This cataclysmic failure of orthodoxy, green religion-based, climate-science-doomsday predictions is now being referred to as one of science's biggest mysteries - a confirmation of 99.9% proof one could surmise, and the public reportedly agrees with.
And let's not forget the proof that the doomsday climate scientists are confirming their own spectacular prediction failures with the recent plethora of excuses.
